Understanding Microcytic Anemia: A Comprehensive Overview

Microcytic anemia is a condition characterized by the presence of smaller-than-normal red blood cells in lower-than-normal quantities. This condition can stem from various underlying causes, primarily related to the body’s inability to produce sufficient hemoglobin. Hemoglobin, a crucial component of blood, is responsible for transporting oxygen to tissues and giving red blood cells their distinctive red color.

The term “microcytic” refers to the diminished size of the red blood cells, while “anemia” indicates a reduced number of properly functioning red blood cells in the body. This combination results in a decreased capacity for oxygen delivery to tissues, leading to various symptoms and health complications.

Key Characteristics of Microcytic Anemia

• Smaller red blood cells (microcytes)
• Reduced number of red blood cells
• Decreased hemoglobin production
• Impaired oxygen transport

Common Causes and Risk Factors for Microcytic Anemia

While iron deficiency is the most prevalent cause of microcytic anemia, several other conditions can lead to this type of anemia. Understanding these causes is crucial for proper diagnosis and treatment.

Iron Deficiency Anemia

Iron deficiency anemia occurs when the body lacks sufficient iron to produce adequate hemoglobin. This deficiency can result from various factors:

• Inadequate dietary iron intake
• Impaired iron absorption due to conditions like celiac disease or Helicobacter pylori infection
• Chronic blood loss (e.g., heavy menstrual periods, gastrointestinal bleeding)
• Increased iron demands during pregnancy

Thalassemia

Thalassemia is an inherited blood disorder characterized by abnormal hemoglobin production. This genetic condition can lead to microcytic anemia due to mutations in the genes responsible for hemoglobin synthesis.

Sideroblastic Anemia

Sideroblastic anemia can be either congenital (inherited) or acquired. In this condition, the body is unable to effectively incorporate iron into hemoglobin, resulting in iron accumulation within red blood cells. Congenital sideroblastic anemia typically presents as microcytic and hypochromic.

Anemia of Chronic Disease

Certain chronic conditions can interfere with normal red blood cell function and iron utilization, potentially leading to microcytic anemia. These conditions include:

• Infectious diseases (e.g., tuberculosis, HIV/AIDS)
• Inflammatory disorders (e.g., rheumatoid arthritis, Crohn’s disease)
• Kidney disease
• Cancer

Recognizing the Symptoms of Microcytic Anemia

Microcytic anemia often develops gradually, and symptoms may not be noticeable in the early stages. As the condition progresses and the shortage of normal red blood cells begins to affect tissue oxygenation, various symptoms may emerge.

Common Symptoms

• Fatigue and weakness
• Decreased stamina
• Shortness of breath, especially during physical exertion
• Dizziness or lightheadedness
• Pale skin
• Rapid heartbeat
• Cold hands and feet
• Chest pain

Are these symptoms always indicative of microcytic anemia? While these symptoms are common in microcytic anemia, they can also be associated with other conditions. It’s essential to consult a healthcare professional for proper diagnosis if you experience persistent symptoms lasting more than two weeks or if you encounter severe dizziness or shortness of breath.

Diagnosing Microcytic Anemia: Tests and Procedures

Accurate diagnosis of microcytic anemia involves a combination of clinical evaluation, patient history, and laboratory tests. Healthcare providers employ various diagnostic tools to identify the underlying cause and determine the most appropriate treatment approach.

Complete Blood Count (CBC)

A CBC is typically the first test ordered when anemia is suspected. This test provides information about the number, size, and characteristics of blood cells, including:

• Red blood cell count
• Hemoglobin levels
• Hematocrit (percentage of blood volume occupied by red blood cells)
• Mean corpuscular volume (MCV) – indicating the average size of red blood cells

Iron Studies

To assess iron status and identify iron deficiency anemia, the following tests may be performed:

• Serum iron
• Ferritin
• Total iron-binding capacity (TIBC)
• Transferrin saturation

Hemoglobin Electrophoresis

This test helps diagnose thalassemia by separating different types of hemoglobin and identifying abnormal variants.

Bone Marrow Examination

In some cases, a bone marrow biopsy may be necessary to diagnose conditions like sideroblastic anemia or to rule out other blood disorders.

Treatment Approaches for Microcytic Anemia

The treatment of microcytic anemia primarily focuses on addressing the underlying cause. The approach varies depending on the specific type of anemia and its severity.

Iron Supplementation

For iron deficiency anemia, oral iron supplements are typically the first-line treatment. These supplements can help replenish iron stores and improve hemoglobin production. In some cases, intravenous iron may be necessary for faster results or in patients who cannot tolerate oral supplements.

Dietary Modifications

Increasing dietary iron intake can be beneficial for preventing and managing iron deficiency anemia. Iron-rich foods include:

• Lean red meat
• Poultry
• Fish
• Beans and lentils
• Dark leafy greens
• Iron-fortified cereals

Treating Underlying Conditions

For microcytic anemia caused by chronic diseases or infections, treating the underlying condition is crucial. This may involve medications, lifestyle changes, or other interventions specific to the causative disorder.

Blood Transfusions

In severe cases of anemia or when rapid improvement is necessary, blood transfusions may be recommended to quickly increase red blood cell count and hemoglobin levels.

Chelation Therapy

For conditions like thalassemia, where iron overload can occur, chelation therapy may be used to remove excess iron from the body.

Preventing Microcytic Anemia: Strategies for Optimal Health

While not all types of microcytic anemia can be prevented, certain lifestyle choices and preventive measures can reduce the risk of developing iron deficiency anemia, the most common form of microcytic anemia.

Balanced Diet

Consuming a diet rich in iron and other essential nutrients is crucial for preventing iron deficiency anemia. Include a variety of iron sources in your meals, such as lean meats, legumes, and fortified grains.

Vitamin C Intake

Vitamin C enhances iron absorption from plant-based sources. Combine iron-rich foods with vitamin C-rich foods like citrus fruits, berries, and bell peppers to maximize iron absorption.

Regular Health Check-ups

Routine blood tests can help detect anemia early, allowing for prompt intervention and treatment.

Managing Chronic Conditions

If you have a chronic condition that increases your risk of anemia, work closely with your healthcare provider to manage the condition effectively and monitor your blood cell counts regularly.

Living with Microcytic Anemia: Coping Strategies and Lifestyle Adjustments

Managing microcytic anemia often requires ongoing care and lifestyle modifications. Implementing certain strategies can help individuals cope with the condition and improve their quality of life.

Energy Conservation

Fatigue is a common symptom of microcytic anemia. Prioritize activities, take frequent rest breaks, and pace yourself throughout the day to conserve energy.

Exercise

While it may seem counterintuitive, regular, moderate exercise can help improve energy levels and overall well-being. Consult with your healthcare provider to determine an appropriate exercise regimen.

Stress Management

Chronic stress can exacerbate anemia symptoms. Incorporate stress-reduction techniques such as meditation, deep breathing exercises, or yoga into your daily routine.

Sleep Hygiene

Prioritize getting adequate, quality sleep to help manage fatigue and support overall health. Establish a consistent sleep schedule and create a relaxing bedtime routine.

Medication Adherence

If prescribed iron supplements or other medications, take them as directed by your healthcare provider. Consistency is key in managing microcytic anemia effectively.

Microcytic Anemia in Special Populations: Considerations and Challenges

Certain groups may be at higher risk for developing microcytic anemia or may face unique challenges in managing the condition. Understanding these special considerations is crucial for effective prevention and treatment.

Pregnant Women

Pregnancy increases the demand for iron, making pregnant women more susceptible to iron deficiency anemia. Regular prenatal check-ups and iron supplementation are often recommended to prevent and manage anemia during pregnancy.

Children and Adolescents

Rapid growth during childhood and adolescence increases iron requirements. Ensuring adequate iron intake through diet or supplements is essential for proper growth and development.

Vegetarians and Vegans

Plant-based diets may be lower in bioavailable iron. Vegetarians and vegans should pay special attention to their iron intake and consider iron supplementation if necessary.

Athletes

Intense physical activity can increase iron loss through sweat and may lead to a higher risk of iron deficiency. Athletes should monitor their iron status and consult with a sports nutritionist for appropriate dietary recommendations.

Elderly Individuals

Older adults may be at increased risk of microcytic anemia due to chronic conditions, medications, or dietary insufficiencies. Regular health screenings and attention to nutrition are important for this population.

In conclusion, microcytic anemia is a complex condition with various causes and manifestations. By understanding its symptoms, causes, and treatment options, individuals can work with their healthcare providers to manage the condition effectively and maintain optimal health. Regular check-ups, a balanced diet, and adherence to prescribed treatments are key components in addressing microcytic anemia and improving overall well-being.

Microcytic anemia means that you have smaller red blood cells than typical — and fewer of them. It can result from an iron deficiency or a health condition.

Microcytic anemia definition

Microcytosis is a term used to describe red blood cells that are smaller than normal. Anemia is when you have low numbers of properly functioning red blood cells in your body.

In microcytic anemias, your body has fewer red blood cells than normal. The red blood cells it does have are also too small. Several different types of anemias can be described as microcytic.

Microcytic anemias are caused by conditions that prevent your body from producing enough hemoglobin. Hemoglobin is a component of your blood. It helps transport oxygen to your tissues and gives your red blood cells their red color.

Iron deficiency causes most microcytic anemias. Your body needs iron to produce hemoglobin. But other conditions can cause microcytic anemias, too. To treat a microcytic anemia, your doctor will first diagnose the underlying cause.

You may not notice any symptoms of microcytic anemia at first. Symptoms often appear at an advanced stage when the lack of normal red blood cells is affecting your tissues.

Common symptoms of microcytic anemias include:

• fatigue, weakness, and tiredness
• loss of stamina
• shortness of breath
• dizziness
• pale skin

If you experience any of these symptoms and they don’t resolve within two weeks, make an appointment to see your doctor.

You should make an appointment to see your doctor as soon as possible if you experience severe dizziness or shortness of breath.

Microcytic anemias can be further described according to the amount of hemoglobin in the red blood cells. They can be either hypochromic, normochromic, or hyperchromic:

1. Hypochromic microcytic anemias

Hypochromic means that the red blood cells have less hemoglobin than normal. Low levels of hemoglobin in your red blood cells leads to appear paler in color. In microcytic hypochromic anemia, your body has low levels of red blood cells that are both smaller and paler than normal.

Most microcytic anemias are hypochromic. Hypochromic microcytic anemias include:

Iron deficiency anemia: The most common cause of microcytic anemia is an iron deficiency in the blood. Iron deficiency anemia can be caused by:

• inadequate iron intake, usually as a result of your diet
• being unable to absorb iron due to conditions like celiac disease or Helicobacter pylori infection
• chronic blood loss due to frequent or heavy periods in women or by gastrointestinal (GI) bleeds from upper GI ulcers or inflammatory bowel disease
• pregnancy

Thalassemia: Thalassemia is a type of anemia that’s caused by an inherited abnormality. It involves mutations in the genes needed for normal hemoglobin production.

Sideroblastic anemia: Sideroblastic anemia can be inherited due to gene mutations (congenital). It can also be caused by a condition acquired later in life that impedes your body’s ability to integrate iron into one of the components needed to make hemoglobin. This results in a buildup of iron in your red blood cells.

Congenital sideroblastic anemia is usually microcytic and hypochromic.

2. Normochromic microcytic anemias

Normochromic means that your red blood cells have a normal amount of hemoglobin, and the hue of red is not too pale or deep in color. An example of a normochromic microcytic anemia is:

Anemia of inflammation and chronic disease: Anemia due to these conditions is usually normochromic and normocytic (red blood cells are normal in size). Normochromic microcytic anemia may be seen in people with:

• infectious diseases, such as tuberculosis, HIV/AIDS, or endocarditis
• inflammatory diseases, such as rheumatoid arthritis, Crohn’s disease, or diabetes mellitus
• kidney disease
• cancer

These conditions can prevent red blood cells from functioning normally. This can lead to decreased iron absorption or utilization.

3. Hyperchromic microcytic anemias

Hyperchromic means that the red blood cells have more hemoglobin than normal. High levels of hemoglobin in your red blood cells makes them a deeper hue of red than normal.

Congenital spherocytic anemia: Hyperchromic microcytic anemias are rare. They may be caused by a genetic condition known as congenital spherocytic anemia. This is also called hereditary spherocytosis.

In this disorder, the membrane of your red blood cells doesn’t form correctly. This causes them to be rigid and improperly spherical shaped. They are sent to be broken down and die in the spleen because they don’t travel in the blood cells properly.

4. Other causes of microcytic anemia

Other causes of microcytic anemia include:

• lead toxicity
• copper deficiency
• zinc excess, which causes copper deficiency
• alcohol use
• drug use

Microcytic anemias are often first spotted after your doctor has ordered a blood test known as a complete blood count (CBC) for another reason. If your CBC indicates that you have anemia, your doctor will order another test known as a peripheral blood smear.

This test can help spot early microcytic or macrocytic changes to your red blood cells. Hypochromia, normochromia, or hyperchromia can also be seen with the peripheral blood smear test.

Your primary care doctor may refer you to a hematologist. A hematologist is a specialist who works with blood disorders. They may be able to best diagnose and treat the specific type of microcytic anemia and identify its underlying cause.

Once a doctor has diagnosed you with microcytic anemia, they will run tests to determine the cause of the condition. They may run blood tests to check for celiac disease. They may test your blood and stool for H. pylori bacterial infection.

Your doctor might ask you about other symptoms you’ve experienced if they suspect that chronic blood loss is the cause of your microcytic anemia. They may refer you to a gastroenterologist if you have stomach or other abdominal pain. A gastroenterologist might run imaging tests to look for different conditions. These tests include:

• abdominal ultrasound
• upper GI endoscopy (EGD)
• CT scan of the abdomen

For women with pelvic pain and heavy periods, a gynecologist may look for uterine fibroids or other conditions that could cause heavier flows.

Treatment for microcytic anemia focuses on treating the underlying cause of the condition.

Your doctor may recommend that you take iron and vitamin C supplements. The iron will help treat the anemia while the vitamin C will help increase your body’s ability to absorb the iron.

Your doctor will focus on diagnosing and treating the cause of the blood loss if acute or chronic blood loss is causing or contributing to microcytic anemia. Women with iron deficiency from severe periods may be prescribed hormonal therapy, such as birth control pills.

In cases of microcytic anemia so severe that you’re at risk for complications like cardiac failure, you may need to get a blood transfusion of donor red blood cells. This can increase the number of healthy red blood cells that your organs need.

Treatment can be relatively straightforward if simple nutrient deficiencies are the cause of microcytic anemia. As long as the underlying cause of the anemia can be treated, the anemia itself can be treated and even cured.

In very severe cases, untreated microcytic anemia can become dangerous. It can cause tissue hypoxia. This is when the tissue is deprived of oxygen. It can cause complications including:

• low blood pressure, also called hypotension
• coronary artery problems
• pulmonary problems
• shock

These complications are more common in older adults who already have pulmonary or cardiovascular diseases.

The best way to prevent microcytic anemia is to get enough iron in your diet. Increasing your vitamin C intake can also help your body absorb more iron.

You can also consider taking a daily iron supplement. These are often recommended if you already have anemia. You should always talk to your doctor before you start taking any supplements.

You can also try to get more nutrients through your food.

Foods rich in iron include:

• red meat like beef
• poultry
• dark leafy greens
• beans
• dried fruits like raisins and apricots

Foods rich in vitamin C include:

• citrus fruits, especially oranges and grapefruits
• kale
• red peppers
• Brussels sprouts
• strawberries
• broccoli

A blood test is one of the most common diagnostic methods that provides information about the state of the patient’s body. A blood test includes the study of parameters such as the number of leukocytes, red blood cells, hemoglobin and ESR.

Leukocytes are white blood cells that perform a protective function in the body. The number of white blood cells in the blood can vary depending on various factors such as infection, inflammation, stress, and others. Therefore, the analysis of the level of leukocytes helps to assess the presence of inflammatory processes and infections in the body.

Erythrocytes are red blood cells that contain hemoglobin. Hemoglobin, in turn, allows the blood to transport oxygen and carbon dioxide. A change in the number of red blood cells may indicate various blood diseases, for example, the manifestation of anemia.

ESR (erythrocyte sedimentation rate) is an indicator that displays how quickly red blood cells settle in the blood plasma. A change in the erythrocyte sedimentation rate may indicate the presence of inflammatory, infectious or other diseases.

Hemoglobin is a protein found in red blood cells. It transfers oxygen in the body and protects against oxygen starvation. Analysis of hemoglobin levels allows you to assess the presence or absence of various diseases, such as anemia or other pathological conditions.

Blood test: indicators and value

Leukocytes

The level of leukocytes in the blood is an important indicator of human health. Leukocytes are white blood cells that are responsible for protecting the body from infection and disease. The normal level of white blood cells in the blood ranges from 4 to 10 thousand per microliter. An elevated level of white blood cells may indicate the presence of an infectious disease in the body, and a low level may indicate an immunodeficiency state.

Red blood cells and hemoglobin

Red blood cells are red blood cells that carry oxygen through the bloodstream. The normal level of red blood cells in the blood is 4.5 to 5.5 million per microliter in men and 4 to 5 million per microliter in women. Hemoglobin is a protein found in red blood cells that binds oxygen and carbon dioxide. The normal hemoglobin level in men is 130 to 160 grams per liter, and in women it is 120 to 140 grams per liter. Low levels of red blood cells and hemoglobin can indicate iron deficiency anemia, injury, blood loss, and elevated levels of hemoglobin can indicate respiratory diseases and other diseases.

ESR

ESR (erythrocyte sedimentation rate) is an indicator that characterizes the rate of erythrocyte sedimentation in a flask over a certain period of time. The normal level of ESR in women is from 2 to 15 mm/hour, and in men – from 1 to 10 mm/hour. Elevated levels of ESR may indicate the presence of inflammatory processes and infections in the body.

Leukocytes: role in blood tests

Leukocytes are white blood cells that protect the body from infections and diseases. Their amount in the blood characterizes the patient’s immune system and may indicate the presence of a disease.

A blood test for leukocytes includes determining their total number and percentage of different types of leukocytes. The total white blood cell count may vary depending on various factors such as physical exertion, stress, infections, etc.

• Neutrophils are the most numerous type of leukocyte responsible for fighting bacterial infections.
• Lymphocytes are the main cells of the immune system responsible for defense against viruses and other pathogens.
• Monocytes are phagocytic cells capable of removing dead and damaged cells from the blood.

Changes in white blood cell count can indicate inflammation, infections, allergies, or even cancer. If anomalies are detected as a result of the analysis, it is recommended to consult a doctor for consultation and additional examinations.

Red blood cells: functions and significance in the blood test

Red blood cells, also known as red blood cells, play a key role in the functioning of the body. They contain hemoglobin, a protein component that is responsible for transporting oxygen from the lungs to the tissues. Red blood cells also play an important role in removing carbon dioxide from tissues and transporting it back to the lungs for excretion from the body.

Red blood cells are usually measured in millions of cells per microliter of blood (µl). The normal level for men is 4.3 to 5.7 million/mcL, for women it is 3.8 to 5.1 million/mcL. A low red blood cell count can indicate various conditions, such as anemia, blood loss or blood loss, as well as the presence of certain diseases, including leukemia and leukemia.

1. Causes of an increase in the level of erythrocytes:
2. Physical activity;
3. Lack of oxygen in the body;
4. Possible diseases such as lung or cardiovascular diseases;
5. Certain hereditary diseases;

• Causes of low red blood cells:
• Anemia;
• Loss of blood or blood loss;
• Certain diseases such as leukemia, leukemia and diseases of the bone marrow;
• Metabolic disorders;

Monitoring the level of red blood cells as a result of a blood test is an extremely important indicator of the health of the body. It allows you to identify the presence of anomalies and diseases, as well as to determine their degree and nature of development. With an increase or decrease in the level of red blood cells, you should consult a specialist and undergo additional studies to determine the causes and prescribe the correct treatment.

ESR

The erythrocyte sedimentation rate (ESR) is a measure that measures the rate of erythrocyte sedimentation in a test tube. This indicator is an important element in the general blood test.

ESR may be elevated in patients with infectious diseases, autoimmune diseases, cancer, and other inflammatory diseases.

• Normal ESR level in men: from 0 to 15 mm/hour.
• Normal ESR in women: 0 to 20 mm/h.

ESR norm, mm/h Women Men

At elevated levels of ESR, it is necessary to conduct additional studies and find out the reason for this increase.

Hemoglobin

Hemoglobin is a protein component of red blood cells (erythrocytes) that is responsible for transporting oxygen from the lungs to tissues and back. Hemoglobin is composed of four subunits, each containing a heme group that binds oxygen and transports it through the blood. Hemoglobin is measured in grams per deciliter of blood (g/dL) and gives an indication of the amount of oxygen the blood can carry.

The normal level of hemoglobin depends on the age and sex of the person. In healthy men, hemoglobin levels range from 13.5 to 17.5 g/dL, and in healthy women, from 12.0 to 15.5 g/dL.

Low hemoglobin (anemia) can occur due to a variety of reasons, including iron deficiency, vitamin B12 deficiency, folic acid deficiency, blood loss, genetic disorders and other diseases. Symptoms of anemia can include lethargy, weakness, dizziness, palpitations, and shortness of breath.

• To maintain a normal level of hemoglobin in the blood, it is necessary: ​​
• – Eat foods rich in iron, such as red meat, animal organs, legumes, green vegetables and dried fruits.
• – Drink enough fluids to reduce the viscosity of the blood and facilitate its circulation.
• – Avoid smoking and excessive alcohol consumption, which can reduce the amount of oxygen available in the blood.

High hemoglobin level , also known as erythrocytosis, may be associated with smoking, altitude, polycythemia (increasing numbers of red blood cells), and other medical conditions.

Hemoglobin (g/dL) Interpretation

Normal values ​​

The blood test includes several parameters that help determine the overall health of the body. The normative values ​​for each parameter usually differ depending on age, gender and other factors.

Leukocytes

The normal level of leukocytes in the blood varies from 4,000 to 10,000 per cubic millimeter. This indicator displays the number of white blood cells that protect the body from infections and diseases. It can increase with inflammation and infectious diseases.

Red blood cells

The level of red blood cells, or red blood cells, also varies with age and sex. Typically, the level of red blood cells in the blood ranges from 4 to 6 million per cubic micrometer in men and from 3.5 to 5.5 million per cubic micrometer in women. This parameter displays the ability of blood to carry oxygen from the lungs to tissues and organs.

ESR

Erythrocyte sedimentation rate, or ESR, is an indicator of inflammation and disease in the body. The normal level of ESR in women is from 0 to 20 mm / h, in men – from 0 to 15 mm / h. However, ESR levels may be elevated in a number of conditions, including infections, autoimmune diseases, and cancers.

Hemoglobin

The hemoglobin level reflects the amount of oxygen carried by the blood. The normal hemoglobin level in men is 13.5 to 17.5 g/dl and in women it is 12.0 to 15.5 g/dl. This setting can be changed for various diseases including anemia, cardiovascular disease and various blood disorders.

How is the blood test for leukocytes, erythrocytes, soy and hemoglobin?

Blood draw

Blood test for leukocytes, erythrocytes, soy and hemoglobin is carried out after taking blood from a vein. For this, a special needle is used, which is used to puncture the skin in the area of ​​\u200b\u200bthe elbow.

After the needle enters the vein, blood with a sterile syringe tube is collected in several samples: each sample is reserved for a certain type of research.

Preparation for analysis

It is recommended to abstain from food for 8-12 hours before testing for leukocytes, erythrocytes, soy and hemoglobin. For the accuracy of the result, it is also important not to smoke or exercise for several hours before taking blood.

It is also important to inform the lab analyzer of all medications you are taking, as some of them may skew the blood test results.

Analysis processing

Blood collected for analysis is sent to a special laboratory. They conduct various studies, which may include counting leukocytes and erythrocytes, measuring hemoglobin and soy.

WBC, RBC, ESR and hemoglobin results are usually available within a few days.

When should I take a blood test for leukocytes, erythrocytes, soy and hemoglobin?

The need for a blood test is due to several factors, including:

• preventive medical examinations;
• onset of disease symptoms;
• disease control;
• confirmation of diagnosis;
• prescribing drugs and monitoring their effectiveness;
• assessment of the functioning of the organism.

A blood test for leukocytes, erythrocytes, ESR and hemoglobin may be ordered by a doctor as part of a preventive medical examination, which is recommended annually. Also, an analysis can be prescribed if the patient has certain symptoms of the disease, such as fever, headache, weakness, anemia, bleeding, and others.

Blood tests for leukocytes, erythrocytes, ESR and hemoglobin are necessary for certain types of medical interventions, such as surgery, childbirth and others. When prescribing drugs, it is also necessary to monitor their effectiveness and observe the correct dosage.

Influence of diet on blood test results

Blood test is an important way to monitor the condition of the body. Leukocytes, erythrocytes, soy and hemoglobin – all these indicators reflect the main functions of the blood. However, few people know that nutrition can also affect them.

However, there are certain foods that can improve blood test results. For example, eating iron-rich foods in moderation can help restore hemoglobin levels. At the same time, an excess of such products can also adversely affect the condition of the blood.

• Recommendations:
• When changing the diet, be sure to pay attention to the blood test results.
• You should not strive for too strict diets, which can lead to a deficiency of useful elements in the body.
• You can include iron-rich foods in your diet by simply controlling their amount.

Interpreting blood test results

Leukocytes

White blood cells (leukocytes) are an important part of the immune system that can protect the body from infections and other diseases. An elevated white blood cell count may indicate an infection or inflammation in the body. A decrease in the level of leukocytes may indicate a decrease in immunity or problems in the bone marrow.

Red blood cells

Red blood cells (erythrocytes) carry oxygen throughout the body. A low red blood cell count can indicate anemia, which can be caused by a variety of causes, including iron deficiency anemia, vitamin deficiencies, and other medical conditions. High red blood cell levels may indicate cardiovascular problems such as polycythemia and hypoxia.

ESR

Erythrocyte sedimentation rate (ESR) is an indicator that reflects the rate of red blood cell sedimentation in the blood. This indicator can be increased in diseases such as rheumatoid arthritis, inflammatory bowel disease and others. However, elevated ESR may also be related to age and other normal factors.

Hemoglobin

Hemoglobin is the protein component of red blood cells that is responsible for transporting oxygen in the body. Low hemoglobin levels can indicate anemia and other conditions. A high level of hemoglobin can indicate problems with the cardiovascular system, such as polycythemia, chronic obstructive pulmonary disease, and others.

Additional tests

Urinalysis

If there are abnormalities in the blood counts of leukocytes, erythrocytes, ESR and hemoglobin, it is necessary to conduct an additional study – urinalysis. This analysis allows you to detect the presence of infectious processes in the urinary tract, determine the level of proteins and glucose in the urine, and also detect the presence of blood, which may indicate the presence of diseases of the kidneys and bladder.

Biochemical blood test

Additionally, a biochemical blood test is performed, which allows you to determine the level of hormones, proteins, lipids, carbohydrates, minerals, etc. As a result of this analysis, you can detect the presence of diseases of the liver, kidneys, diabetes, metabolic disorders, etc.

Bone marrow biopsy

If leukemia or other blood disorders are suspected, a bone marrow biopsy is performed. During the study, a small sample of bone marrow tissue is taken, which is examined for the presence of malignant cells and other abnormalities.

• Additional examinations provide a complete picture of the state of health.
• Some diseases can only be identified with additional tests.
• After receiving the results of tests and studies, the doctor prescribes the correct treatment and recommendations for the patient.

What is microcytic anemia?

Microcytic anemia is a condition in which smaller red blood cells circulate in the blood than in a healthy person.
human Source:
Anemia. Saraeva N.O. Educational
allowance for students. Irkutsk State Medical University of the Federal Agency for
health care and social development. 2009. pp.70-78. Small red blood cells contain
less hemoglobin, which means they carry a small amount of oxygen. Against this background, oxygen
tissue starvation – hypoxia, which causes the symptoms of microcytic anemia. The disease is congenital
and acquired, the tactics of treatment depend on the cause.

Varieties

All microcytic anemia due to development are classified into two large groups – congenital and acquired. Congenital microcytic anemias include:

• alpha thalassemia;
• beta thalassemia;
• sideroblastic anemia.

Acquired forms:

• iron-deficient;
• sideropenic;
• anemia of chronic disease.

All varieties of anemia are characterized by a decrease in the volume of erythrocytes, a change in their shape.

The classification includes three degrees of disease severity:

• mild – hemoglobin 90-110 g/l;
• medium – hemoglobin 70-90 g/l;
• severe – hemoglobin less than 70 g / l.

Causes of development

Thalassemias are congenital forms of microcytic anemia in which hemoglobin synthesis is disturbed. There are alpha and beta forms of the disease. The most common in Africa, South Asia, the countries of the Mediterranean region. The cause of thalassemia is mutations in the genes responsible for the synthesis of hemoglobin Source:
Molecular basis of hereditary microcytic anemia due to defects in iron absorption or heme synthesis. Iolascon A, De Falco L, Beaumont S. Hematology. 2009. pp. 395-408.

Genetic mutations also cause sideroblastic anemia. At the same time, the bone marrow uses an insufficient amount of iron for the synthesis of hemoglobin, even if its reserves in the body are not depleted. A small amount of red blood cells and hemoglobin enters the blood – such anemia is called microcytic hypochromic anemia.

Causes of acquired microcytic anemias:

• malnutrition, in which an insufficient amount of iron enters the body;
• accelerated consumption of iron during inflammation, infections;
• deficiency of vitamins B6 and C;
• poisoning with salts of heavy metals;
• long-term use of hemotoxic drugs;
• chronic blood loss;
• myelodysplastic syndrome;
• renal and hepatic insufficiency.

Clinical picture

The symptoms of congenital microcytic anemia are similar, and their severity depends on the characteristics of the genetic mutation, the ratio of normal and defective hemoglobin. In patients with minor genetic abnormalities, anemia is asymptomatic. Violations in all the genes responsible for the synthesis of hemoglobin lead to intrauterine death of the fetus, since the blood is not at all able to carry oxygen.

Clinical picture of thalassemia in early childhood:

• moon face;
• saddle bridge;
• tower skull;
• large upper jaw;
• enlargement of the liver and spleen.

Against the background of thalassemia, lesions of the liver, spleen and heart develop. Patients are at high risk of infectious diseases.

Anemia syndrome is characteristic of all types of microcytosis:

• chronic fatigue;
• pale and dry skin;
• hair loss, brittleness and deformity of nails;
• attacks of vertigo;
• episodes of loss of consciousness.

Clinical sideroblastic anemia consists of the actual anemic syndrome and signs of iron accumulation in the tissues:

• enlargement of the liver and spleen;
• gradual formation of cirrhosis of the liver;
• heart enlargement;
• arrhythmias, the formation of heart failure;
• high risk of male and female infertility.

Iron deficiency anemia is acquired in nature, occurs due to low intake of iron in the body, its rapid consumption or malabsorption in the intestine. Specific manifestations of IDA:

• abnormal taste preferences;
• impaired sense of smell;
• goosebumps.

Anemia of chronic diseases is a symptom that occurs with infections, autoimmune and oncological pathologies, kidney damage. At the beginning of development, anemia has a normocytic character, that is, red blood cells in the blood of normal size and shape. Gradually, there is a violation of iron metabolism, and anemia becomes microcytic. Symptoms consist of manifestations of an anemic syndrome and signs of the underlying disease. Specific manifestations:

• weight loss;
• prolonged subfebrile condition;
• pain syndrome.

Examination for microcytic anemia is aimed at finding the cause of the disease, determining the severity of anemia, and assessing the prognosis. Diagnostics includes the following tests and studies:

• general clinical blood tests;
• determination of the amount of iron in blood serum;
• study of ferritin reserves;
• ultrasound examination of the abdominal organs, kidneys;
• bone marrow puncture followed by histological examination Source:
  Anemic syndrome: differential diagnosis and treatment. Budnikova N.V., Arkhipova S.L., Kalinina N.Yu. Textbook for students studying in the specialty “Medicine”. 2013. p.74.

Patients with suspected congenital origin of anemia should consult a hematologist, geneticist.

Laboratory signs of all types of microcytic anemia are similar:

• decrease in hemoglobin less than 115 g/l;
• decrease in color index less than 0.85;
• microcytosis – reduction in the size of erythrocytes;
• young forms of erythrocytes in peripheral blood;
• increased serum iron, ferritin;
• myeloid hyperplasia on bone marrow examination.

Treatment strategy

Treatment of microcytic anemia depends on its form. General principles of treatment:

• influence on the cause of the disease;
• correction of blood parameters;
• symptomatic treatment.

Mild, asymptomatic thalassemia does not require treatment. With clinically expressed forms, only pathogenetic and symptomatic treatment is possible, which begins already from the birth of a child:

• erythrocyte mass transfusion;
• administration of chelating agents to bind excess iron Source:
  Microcytosis/Microcytic anemia. Kamashella K., Brugnara K.N. 2022.;
• taking glucocorticoids in hemolytic crisis;
• taking folic acid and vitamin B12;
• removal of the spleen with its rapid growth.

Treatment of acquired sideroblastic anemia:

• influence on the cause – treatment of the underlying disease, withdrawal of medications taken, exclusion of harmful factors at work;
• administration of chelating agents to bind excess iron;
• taking vitamin B6;
• taking folic acid;
• treatment with hepatoprotectors, antioxidants, cardiac agents.

Treatment of iron-deficiency anemia includes:

• nutrition correction with the inclusion in the diet of products that provide replenishment of iron reserves;
• treatment of gastrointestinal diseases that impair iron absorption;
• detection and elimination of sources of chronic bleeding – hemorrhoids, anal fissure, intestinal inflammation;
• replenishment of iron deficiency by taking iron-containing preparations;
• taking folic acid, vitamin C.

The treatment of anemia of chronic disease is to treat the underlying pathology that caused the anemia. With a pronounced decrease in hemoglobin, iron and folic acid preparations are indicated.

The prognosis for mild forms of thalassemia is favorable. In severe forms with severe symptoms, patients rarely survive even to a young age. Prevention of thalassemia consists in carefully planning pregnancy or refusing to have children in couples where one or both partners are carriers of defective genes. Source:
Microcytic hypochromic anemia. Chaudhry H.S., Casarla M.R. Stat Pearls Publishing. 2022..

The prognosis for congenital sideroblastic anemia is uncertain. In a severe course of the disease, multiple organ failure is quickly formed, patients die. Acquired forms of sideroblastic anemia have a more favorable prognosis and are easier to treat. Prevention is possible only in relation to acquired forms, it consists in maintaining a healthy lifestyle, timely treatment of diseases provoking anemia.

The prognosis for iron deficiency anemia is favorable in most cases. Adequate correction of nutrition and course intake of iron preparations lead to complete recovery. Prevention of IDA consists in a balanced diet, timely detection and treatment of diseases of the digestive system.

The prognosis for anemia of chronic disease depends on the causative pathology. Anemia itself poses less of a threat to health than the underlying disease.
