Low Hematocrit Reasons: Understanding Hemoglobin Tests and Abnormal Levels
What are the typical ranges for hemoglobin levels. How do age and gender affect hemoglobin levels. What causes low hemoglobin levels. What are the symptoms of anemia. How is a hemoglobin test performed.
Understanding Hemoglobin and Its Importance
Hemoglobin (Hgb) is a crucial protein produced by bone marrow and stored in red blood cells. Its primary function is to transport oxygen from the lungs to various parts of the body through arteries. Additionally, hemoglobin plays a vital role in carrying carbon dioxide (CO2) from body tissues back to the lungs through veins. This protein is responsible for giving red blood cells their characteristic red color.
Abnormal hemoglobin levels, whether high or low, can lead to various symptoms, including fatigue, dizziness, and shortness of breath. Healthcare providers often recommend hemoglobin tests to diagnose underlying conditions when patients experience these symptoms.
The Hemoglobin Test Procedure
A hemoglobin test involves analyzing a blood sample to determine hemoglobin levels. The process typically includes:
- Drawing blood from a vein, usually in the arm’s crease
- Alternatively, a finger prick may be used for smaller samples
- Collecting the blood in a tube for laboratory analysis
The procedure is generally quick, lasting less than a minute, though some individuals may experience brief discomfort during the needle insertion. Those sensitive to blood draws should inform their healthcare provider and consider bringing a companion for support.
Reasons for Ordering a Hemoglobin Test
Healthcare providers may order a hemoglobin test for various reasons, often as part of a complete blood count (CBC). Some common scenarios include:
- Family history of blood disorders (e.g., sickle cell anemia)
- Presence of an infection
- Suspected iron deficiency in the diet
- Significant blood loss due to surgery or injury
- Pregnancy
- Medical conditions that may affect hemoglobin levels
While fasting is not typically required for a hemoglobin test, patients should consult their healthcare provider about any necessary preparations, especially if additional blood chemistry tests are planned simultaneously.
Normal Hemoglobin Levels and Factors Affecting Them
Hemoglobin levels can vary based on several factors, primarily age and gender. Understanding these variations is crucial for accurate interpretation of test results.
Typical Hemoglobin Ranges
Generally, normal hemoglobin levels are as follows:
- For men: Above 13 g/dL
- For non-pregnant women: Above 12 g/dL
It’s important to note that these thresholds may vary depending on specific conditions and laboratory reference ranges. Healthcare providers should always consider individual circumstances when interpreting results.
Age and Gender Considerations
Hemoglobin levels can fluctuate significantly in children, especially infants under six months old. As individuals age, their hemoglobin levels tend to stabilize within the adult ranges mentioned above. Gender also plays a role, with men typically having higher hemoglobin levels than women due to the influence of testosterone on red blood cell production.
Low Hemoglobin Levels and Anemia
Low hemoglobin levels are often associated with anemia, a condition characterized by an insufficient number of red blood cells in the body. Anemia can manifest in various ways, and its symptoms may include:
- Extreme fatigue
- Pale skin
- Shortness of breath
- Irregular or rapid heartbeat
- Chest pain
- Cold hands and feet
- Headaches
- Difficulty with physical activities
It’s crucial to understand that while fatigue is a common symptom of anemia, it is not a cause of low hemoglobin. The fatigue experienced in anemia results from decreased oxygen delivery to vital organs and muscles due to the reduced hemoglobin levels.
Causes of Low Hemoglobin Levels
Various factors can contribute to low hemoglobin levels, affecting either the body’s ability to produce red blood cells or the number of red blood cells in circulation. Some common causes include:
Nutritional Deficiencies
- Iron deficiency: Inadequate iron intake can hinder bone marrow’s ability to produce hemoglobin
- Folate or vitamin B-12 deficiency: These nutrients are essential for red blood cell production
Blood Loss
- Severe blood loss from surgery or major injuries
- Internal bleeding from conditions such as stomach ulcers or gastrointestinal cancers
- Heavy menstrual bleeding
Medical Conditions
- Sickle cell anemia: A genetic disorder affecting the shape and function of red blood cells
- Hypothyroidism: Reduced thyroid hormone production can impact red blood cell formation
- Splenomegaly: An enlarged spleen can trap and destroy red blood cells
- Bone marrow disorders: Conditions like leukemia can interfere with red blood cell production
- Chronic kidney disease: Impaired kidney function can lead to reduced erythropoietin production, a hormone crucial for red blood cell formation
Other Factors
- Frequent blood donation
- Alcohol misuse
- Chronic diseases affecting red blood cell production or lifespan
Diagnosing and Treating Low Hemoglobin Levels
When low hemoglobin levels are suspected or detected, healthcare providers typically follow a systematic approach to diagnosis and treatment:
Diagnostic Process
- Review of medical history and symptoms
- Physical examination
- Blood tests, including complete blood count (CBC) and iron studies
- Additional tests as needed, such as bone marrow biopsy or genetic testing
Treatment Options
Treatment for low hemoglobin levels depends on the underlying cause and may include:
- Iron supplementation for iron-deficiency anemia
- Vitamin B12 or folate supplements for deficiency-related anemia
- Medications to stimulate red blood cell production
- Blood transfusions for severe cases
- Treatment of underlying conditions (e.g., addressing chronic kidney disease or hypothyroidism)
- Dietary changes to increase iron and nutrient intake
Preventing Low Hemoglobin Levels
While not all causes of low hemoglobin can be prevented, certain lifestyle choices and preventive measures can help maintain healthy levels:
Dietary Considerations
- Consume iron-rich foods such as lean meats, leafy greens, and fortified cereals
- Include vitamin C-rich foods to enhance iron absorption
- Ensure adequate intake of folate and vitamin B12 through diet or supplements
Lifestyle Factors
- Avoid excessive alcohol consumption
- Manage chronic conditions effectively
- Adhere to recommended intervals between blood donations
Regular Health Check-ups
Routine medical check-ups and blood tests can help detect and address potential hemoglobin issues early, preventing more severe complications.
The Impact of Hemoglobin Levels on Overall Health
Hemoglobin plays a crucial role in overall health and well-being. Maintaining optimal hemoglobin levels is essential for:
- Ensuring adequate oxygen supply to tissues and organs
- Supporting energy production and physical performance
- Maintaining cognitive function and mental clarity
- Supporting immune system function
- Promoting healthy skin, hair, and nail growth
Understanding the significance of hemoglobin and regularly monitoring its levels can contribute significantly to maintaining good health and preventing various complications associated with abnormal hemoglobin levels.
Hemoglobin Testing in Special Populations
Certain groups may require more frequent or specialized hemoglobin testing due to their unique health considerations:
Pregnant Women
Pregnancy increases the body’s demand for iron and other nutrients essential for hemoglobin production. Regular hemoglobin testing during prenatal check-ups helps monitor maternal health and ensure proper fetal development.
Athletes
Endurance athletes, in particular, may undergo regular hemoglobin testing to optimize their performance and detect any exercise-induced anemia. Some athletes may even attempt to artificially increase their hemoglobin levels, a practice known as blood doping, which is both dangerous and prohibited in competitive sports.
Individuals with Chronic Diseases
People with conditions such as diabetes, heart disease, or kidney disease may require more frequent hemoglobin testing as part of their ongoing health management. These conditions can impact hemoglobin levels and overall blood health.
Older Adults
As people age, the risk of developing anemia increases due to various factors, including nutritional deficiencies, chronic diseases, and medications. Regular hemoglobin testing in older adults can help detect and address age-related anemia promptly.
By understanding the importance of hemoglobin and its impact on various aspects of health, individuals can take proactive steps to maintain optimal levels and seek appropriate medical care when necessary. Regular check-ups, a balanced diet, and a healthy lifestyle all contribute to maintaining proper hemoglobin levels and overall well-being.
What Could Cause Low or High Levels
The typical range for Hgb varies by age, sex, and whether you are pregnant. High or low results may occur with certain health conditions, including anemia, internal bleeding, and diseases affecting the heart, lungs, or kidneys.
What is the Hgb test?
The hemoglobin (Hgb) test measures how much hemoglobin your red blood cells contain.
Hgb is a protein produced by your bone marrow that’s stored in red blood cells. It helps red blood cells transport oxygen from your lungs to your body through your arteries.
It also transports carbon dioxide (CO2) from around your body back to your lungs through your veins. Hgb is what makes red blood cells look red.
Abnormally high or low Hgb can cause symptoms like exhaustion, dizziness, or shortness of breath. Your doctor may suggest an Hgb test if you’re experiencing these symptoms. You may have an underlying condition that needs to be diagnosed.
Learn why you may need an Hgb test, what the typical ranges are for Hgb, and what can cause abnormal Hgb levels.
The Hgb test uses a sample of your blood to determine hemoglobin levels.
To take a sample, your healthcare professional extracts blood from a vein by pricking your finger or inserting a needle with an attached tube into the crease of your arm. The sample is then stored in the tube to be analyzed later at a lab.
The needle may cause brief discomfort, but the insertion usually lasts less than a minute. If you’re sensitive to getting blood drawn or the sight of blood, have someone come with you and let your provider know.
The Hgb test may be ordered as part of a complete blood count (CBC) test. A CBC test also measures other important components of your blood, such as white blood cells and platelets. Abnormal levels of any of these cells can indicate underlying conditions or blood disorders.
Here are a few other reasons your doctor may order an Hgb test:
- You have parents or other family members who have blood disorders, such as sickle cell anemia.
- You have an infection.
- You don’t have enough iron in your diet.
- You’ve lost a lot of blood after surgery or a traumatic injury.
- You’re pregnant.
- You have a medical condition that can affect your Hgb levels.
You don’t need to fast for the Hgb test specifically. You may need to fast — avoiding food or liquids with calories for about 12 hours — if your doctor plans to test the chemistry of your blood at the same time. You should drink plenty of water, however.
Your age and gender both affect your Hgb levels. Typical healthy Hgb levels are as follows:
For men, Hgb levels below 13 g/dL are considered low. For women, Hgb levels below 12 g/dL are considered low if not pregnant.
This threshold may change with certain conditions. It can also vary depending on the lab, so be sure to check your lab’s reference range. For children these levels may also vary due to age, especially in infants under 6 months old.
Low Hgb is also known as anemia, which means that you don’t have enough red blood cells in your body.
With anemia, a blood test will also show that you have a low red blood cell count and may have low hematocrit, the volume of red blood cells to other components in your blood.
Anemia can have many causes, so symptoms vary widely. Common anemia symptoms can include:
- exhaustion
- skin paleness
- shortness of breath
- abnormal or rapid heartbeat
- pain in your chest
- cold, swollen hands or feet
- headache
- trouble with physical activity
While exhaustion or fatigue isn’t a cause of low hemoglobin, it can be a symptom. A lower than normal amount of hemoglobin can result in decreased oxygen delivery to vital organs and muscles, resulting in fatigue or a lack of energy.
Low Hgb levels can be caused by any condition that affects your body’s ability to create red blood cells or conditions that lower red blood cells in your bloodstream.
Possible causes of low Hgb include:
- lack of iron in your diet, which makes it harder for your bone marrow to produce Hgb
- lack of folate or vitamin B-12, which can lead to your body producing fewer red blood cells than are needed
- severe blood loss after surgery or a major injury
- internal bleeding from stomach ulcers, stomach or colon cancer, or internal injuries
- sickle cell anemia, a genetic condition that causes red blood cells to be abnormally sickle-shaped and able to carry less Hgb
- hypothyroidism, which means that the thyroid gland doesn’t produce enough thyroid hormones
- splenomegaly, or an enlarged spleen from infection, liver conditions, or cancer
- bone marrow conditions, such as leukemia, that prevent your bone marrow from producing enough red blood cells
- chronic kidney disease, in which your kidneys don’t function properly (resulting in a deficiency of erythropoietin, a hormone that stimulates red blood cell production in your bone marrow)
Other causes can include:
- donating blood too often
- heavy bleeding during your period
- alcohol misuse
- chronic health problems such as autoimmune diseases or cancer
High Hgb is known as polycythemia. This means you have too many red blood cells.
Polycythemia vera is a cancer of the blood in which your bone marrow overproduces red blood cells.
With polycythemia, a blood test also shows that you have a high red blood cell count and high hematocrit.
Common symptoms of high Hgb levels include:
- itchiness
- headache
- dizziness
- getting easily bruised or bleeding
- sweating more than usual
- painful joint swelling
- abnormal weight loss
- a yellow tint to the eyes and skin (jaundice)
- feeling exhausted
- a purple or reddish tint to the skin
High Hgb may result from your body needing to store more Hgb in red blood cells due to your environment, a condition that affects your heart or lung function, or lifestyle choices.
Possible causes of high Hgb levels include:
- living at high altitudes where there’s not as much oxygen in the air, such as in the mountains
- smoking tobacco products, including cigarettes or cigars
- chronic obstructive pulmonary disease (COPD), a condition that inflames the lungs and blocks air from getting into your lungs
- heart or lung diseases that affect your ability to breathe, your lungs’ ability to pass oxygen into your bloodstream, or your heart’s ability to pump normally
- taking erythropoietin unnecessarily, such as to enhance high-level physical performance
Other causes include:
- being severely dehydrated
- heart failure
- cancer of the liver or kidneys
Your doctor may recommend a Hgb test if you have symptoms of abnormal Hgb levels or if you’re pregnant.
The earlier you notice the symptoms of abnormal Hgb levels and have the cause diagnosed, the more likely you are to have successful treatment.
See your doctor if you’re experiencing any symptoms of high or low Hgb. If you have a family history of blood disorders or conditions that can affect bone marrow or red blood cell production, you’ll likely need regular Hgb tests along with a CBC to monitor how these health problems may be affecting your blood cells.

Justification
Hemoglobin (Hb) and hematocrit (Hct) are the most commonly used tests to screen for iron deficiency anemia. Measurements of Hb and Hct reflect the amount of functional iron in the body. Changes in Hb concentration and Hct occur at the late stages of iron deficiency. While neither Hb nor Hct test are direct measures of iron status and do not distinguish among different types of anemia, these tests are useful indicators of iron deficiency anemia.
Iron deficiency is by far the most common cause of anemia in children and women of childbearing age. It may be caused by a diet low in iron, insufficient assimilation of iron from the diet, increased iron requirements due to growth or pregnancy, or blood loss. Anemia can impair energy metabolism, temperature regulation, immune function, and work performance. Anemia during pregnancy may increase the risk of prematurity, poor maternal weight gain, low birth weight, and infant mortality. In infants and children, even mild anemia may delay mental and motor development. The risk increases with the duration and severity of anemia, and early damages are unlikely to be reversed through later therapy.

Clarification
Basis for blood work assessment: For pregnant women being assessed for iron deficiency anemia, blood work must be evaluated using trimester values established by CDC. Thus, the blood test result for a pregnant woman would be assessed based on the trimester in which her blood work was taken.
Definition of Trimester: CDC defines a trimester as a term of three months in the prenatal gestation period with the specific trimesters defined as follows in weeks:
- First Trimester: 0-13 weeks
- Second Trimester: 14-26 weeks
- Third Trimester: 27-40 weeks
Further, CDC begins the calculation of weeks starting the first day of the last menstrual period. If that date is not available, CDC estimates that date from the estimated date of confinement (EDC). This definition is used in interpreting CDC’s Prenatal Nutrition Surveillance System data, comprised primarily of data on pregnant women participating in the WIC Program.

Find out what red blood cell values are considered normal, how they change with age, and what low and high values can mean. Useful information for the health of your blood.
Blood not only nourishes the body, but also transports all the necessary elements. Erythrocytes are red blood cells that transport oxygen. They are the main component of the blood and their normal content is necessary for the normal functioning of the body. However, red blood cell count can change for various reasons, including the age of the individual.
Erythrocyte norms have their own characteristics for different age groups. In children, for example, the number of red blood cells depends on age, while in adults it may vary depending on gender. The need to know the normal level of erythrocytes in the blood by age is important for the diagnosis and treatment of diseases associated with a violation of the content of blood cells.
In this article, we will look at the main reasons for the increase and decrease in the number of red blood cells in the blood, and provide information on how to maintain their normal level.
What are red blood cells?
Red blood cells are blood cells that carry out the function of transporting oxygen from the lungs to the tissues of the body and removing carbon dioxide back to the lungs for exhalation.
RBCs are oval or round discs without a nucleus. They contain hemoglobin, a protein compound with iron, which is responsible for the transfer of oxygen and carbon dioxide.
Typically, erythrocytes have a size of about 7-8 microns, and their number in 1 µl of blood is estimated by Kuhn’s method – erythrocyte index (EI), which can be normal, increased or decreased depending on the patient’s age and other factors.
The norm of red blood cells in the blood of an adult
Red blood cells are red blood cells that carry oxygen throughout the body. The normal number of red blood cells in an adult’s blood is 4.0 to 5.5 million cells/µl in women and 4.5 to 6.0 million cells/µl in men.
An elevated red blood cell count may indicate polycythemia, leading to nodular disease, tumors, and vascular complications. An increase in the level of red blood cells may be associated with smoking, hypoxia and erythroprotein.
To confirm the change in the level of red blood cells in the blood, you must consult a doctor and undergo the necessary tests, such as blood tests for hemoglobin, iron, folic acid and vitamin B12.
The norm of red blood cells in children
Red blood cells are red blood cells that carry oxygen throughout the body. In children, as in adults, the rate of red blood cells in the blood can vary depending on age and gender. In healthy children, normal values of red blood cells are usually higher than in adults.
Here are some examples of normal RBC values in children:
- Babies under 2 weeks old: 4.1-6.1 million/µl
- Babies 2 weeks to 1 month: 4.3-6.0 million/µl
- Children 1 month to 2 months: 4.0-5.5 million/µL
- Children 2 to 6 months: 3.6-5.5 million/µL
- Children 6 months to 1 year: 3.5- 5.5 ppm/µl
- Children 1-5 years old: 3.5-5.0 ppm/µl
- Children 5-12 years old: 4.0-5.0 ppm/µl
- Children 12 to 16 years: 4.5-5.5 million/mcL
An increased number of red blood cells in children may indicate diseases such as polycythemia and vitamin B12 deficiency. On the other hand, a reduced red blood cell count can mean anemia, which can be caused by causes such as lack of iron in the body or genetic diseases such as thrombocytopenia.
It is important to understand that red blood cell counts in children may vary depending on the laboratory and measurement methods used. Therefore, if your child is found to be abnormal, discuss the test results with your doctor for a more accurate diagnosis and treatment.
Causes of an increase in the level of red blood cells in the blood
Red blood cells are the main components of blood that carry oxygen to the body. An excessive number of red blood cells in the blood is called polycythemia, which may indicate certain medical conditions.
- Hypoxia – oxygen starvation of the body – can lead to an increase in the level of red blood cells, as the body tries to compensate for the lack of oxygen.
- Physical stress, including mountain running or smoking, can increase the number of red blood cells.
- Hereditary factors, including a genetic positive reaction to altitude, may cause elevated red blood cells.
- Familiarity with Altai cuisine draws people to iron-rich fish, meat and shellfish, so elevated iron levels in the blood can also lead to an increase in red blood cells.
There are several other conditions that can cause high red blood cells and it is important to get the right treatment to prevent complications.
Causes of low red blood cells
Low red blood cells can be caused by several causes, including:
- Blood loss . Prolonged bleeding can lead to a decrease in the number of red blood cells in the blood.
- Iron deficiency . Lack of iron in the body can lead to the development of anemia, a condition characterized by low levels of hemoglobin in the blood.
- Bone marrow pathologies . Disorders in the bone marrow can lead to a decrease in the number of red blood cells, since this is the site of the formation of new blood cells.
- Vitamin deficiency . A lack of certain vitamins, such as vitamin B12 and folic acid, can lead to low levels of red blood cells.
- Genetic disorders . Hereditary diseases such as thrombocytopenia and Diamond-Blackford syndrome can lead to low levels of red blood cells.
With a low level of red blood cells, symptoms may occur, such as weakness, fatigue, pallor of the skin and mucous membranes. It is necessary to consult a doctor to find out the cause and prescribe treatment.
Symptoms of high red blood cells
A high level of red blood cells, or polycythemia, can lead to a variety of symptoms and complications. One of the most common symptoms is headache, which usually occurs in the morning and may worsen with exercise or low oxygen pressure.
An increased red blood cell count can also lead to decreased appetite, nervousness and irritability, as well as a feeling of thirst and dry mouth. In some cases, pallor of the skin and mucous membranes, as well as visual or hearing impairment, may develop.
It is important to note that some people with polycythemia may not experience any symptoms, especially in the earlier stages of the disease. Therefore, it is important to undergo regular examinations and monitor changes in the level of red blood cells in the blood.
Symptoms of low red blood cells
A decrease in the number of red blood cells, or anemia, can present with various symptoms, depending on the degree and cause of the deficiency.
One of the most common symptoms is constant fatigue and weakness that occurs with any physical activity or even at rest.
Paleness of the skin, mucous membranes and nails is also a common symptom, caused by a lack of oxygen transported by red blood cells.
More severe cases of anemia may also present with dyspnea, palpitations, dizziness, and loss of consciousness.
In addition, a lack of red blood cells can lead to changes in taste, visual distortion and even depressive states.
It is important to note that the symptoms of anemia can vary in degree and depend on many factors, including the cause, age and health of the patient.
Diagnosis of the level of erythrocytes in the blood
To determine the level of erythrocytes in the blood, it is necessary to pass a general blood test. The results of the analysis can be expressed in different units of measurement, depending on the laboratory where the analysis is performed.
If the red blood cell count is low, additional diagnostics may be ordered, such as testing for iron deficiency anemia or aplastic anemia. In some cases, a bone marrow exam may be ordered to determine the cause of the low red blood cell count.
- Iron deficiency anemia is a disease in which the body does not get enough iron. This causes a violation of the formation of hemoglobin and, as a result, a decrease in the level of red blood cells in the blood.
- Aplastic anemia is a disease in which the bone marrow does not produce enough blood-forming cells. This can be caused by both genetic factors and exposure to certain drugs or radiation.
In the case of elevated red blood cells, additional diagnostics can be performed, such as examination for obesity, obstructive sleep apnea or cardiovascular disease. In some cases, artificial circulation may be prescribed to reduce the number of red blood cells in the blood. 912 / l
Treatment of elevated red blood cells
Basic treatment principles
blood tests may indicate the presence of serious diseases, such as acute or chronic obstructive pulmonary disease , bronchial asthma, erythremia and others. Treatment should be aimed at eliminating the underlying disease and reducing the level of red blood cells in the blood.
In case of respiratory diseases, it is necessary to carry out complex treatment, including drug therapy, daily routine, diet and maintaining an optimal level of oxygen in the blood.
Diet with high red blood cells
If you have high red blood cells, it is recommended to avoid foods that increase the level of iron in the blood: red meat, fried foods, chicken eggs, pomegranates and tomatoes. It is recommended to increase the consumption of foods rich in vitamins C and E, such as citrus fruits, strawberries, dried apricots, apricots and nuts, which help improve metabolic processes in the body and reduce the level of red blood cells.
Regular medical check-ups
Regular medical check-ups are an important part of treating high red blood cells. With an increase in the level of erythrocytes in the blood, it is necessary to consult a doctor in a timely manner and conduct regular studies in order to evaluate the effectiveness of treatment and adjust the treatment course depending on changes in the level of erythrocytes.
Treatment for low red blood cells
Causes of low red blood cells
A low level of red blood cells can be caused by various reasons, such as: impaired blood formation, impaired absorption of nutrients, blood loss, chronic diseases, genetic disorders.
Treatment for low red blood cells
The course of treatment for low red blood cells depends on the cause of the condition. To increase the number of red blood cells, preparations containing iron, vitamins and minerals are prescribed. In some cases, a blood transfusion may be required, in which the patient is transfused with donor blood.
Health and nutrition should be taken care of to prevent low red blood cells. Regular consumption of foods rich in iron, vitamins and minerals will help maintain a normal level of red blood cells.
- Taking preparations containing iron, vitamins and minerals
- Blood transfusion
- Maintaining a healthy lifestyle and proper nutrition this state.
Foods rich in iron: Foods rich in vitamins and minerals:
meat chickpeas beets buckwheat 90 210
fruit vegetables nuts red pepper Prevention changes in the level of erythrocytes in the blood
One of the main methods for preventing an increase in the level of erythrocytes in the blood is to maintain a healthy lifestyle. It is necessary to monitor nutrition, drink enough water, lead an active lifestyle and avoid smoking and drinking alcohol.
It is also important to have regular medical examinations and blood tests, especially for people with an increased risk of developing erythrocytosis – these are people with diseases of the cardiovascular system, miners and high-altitude workers, people with kidney diseases and hormonal disorders.
In addition, with a low level of red blood cells in the blood, it is recommended to increase the intake of food containing iron, vitamin B12 and folic acid. It can be meat, fish, eggs, green vegetables, fruits and nuts. It is also necessary to avoid significant blood loss and avoid stressful situations that can cause a change in the level of red blood cells in the blood.
- Summary: maintain a healthy lifestyle, get regular medical check-ups and blood tests, eat foods rich in iron, vitamin B12 and folic acid, avoid significant blood loss and stressful situations.

Q&A:
What are normal RBC counts for babies?
In the blood of newborns and infants, the normal number of red blood cells is between 3.9up to 5.9 million per microlitre.
What can cause a low level of red blood cells?
A low red blood cell count can be caused by a variety of causes such as iron deficiency, chronic disease, blood loss, anemia and genetic disorders.
What processes in the body lead to an increase in the number of red blood cells?
Elevated RBC values can be caused by both physiological processes such as high-altitude hypoxia and pathological conditions such as polycythemia, hypoxia, kidney disease, leukemia and other diseases.
Can diet affect the level of red blood cells?
Yes, diet can affect the level of red blood cells. Insufficient intake of iron, vitamin B12, or folic acid can lead to anemia and a low red blood cell count.
Why do athletes have an increased number of red blood cells?
In athletes, an increased number of red blood cells may be caused by the body’s adaptation to high stress, as well as an increase in the production of erythropoietin, a hormone that stimulates the production of red blood cells in the body.
What complications can occur with prolonged high red blood cells?
Elevated red blood cells can lead to complications such as increased risk of thrombosis, high blood pressure, increased risk of heart and vascular disease, increased blood viscosity, and reduced blood oxygen potential.
Anemia
Anemia is a pathological condition caused by a decrease in the number of red blood cells and / or a decrease in the concentration of hemoglobin in the red blood cells themselves.
Erythrocytes (red blood cells, RBCs) are the largest population of blood cells. Red blood cells contain hemoglobin (Hb), which in the lungs attaches oxygen molecules and delivers them to tissues. In the opposite direction – from the tissues to the lungs – hemoglobin carries carbon dioxide molecules. In other words, hemoglobin provides the process of respiration. The erythrocyte has the shape of a disc, concave on both sides. Such a device significantly increases the surface area on which gas exchange occurs. Erythrocytes are small in size, which allows them to pass through the narrowest blood vessels (capillaries, arterioles, venules). One erythrocyte lives on average up to 120 days.
Low hemoglobin is one of the criteria that you need to pay attention to not only when diagnosing anemia itself, but also to assess their severity. A decrease in the amount of hemoglobin in erythrocytes occurs when there is insufficient supply of iron during the maturation of cells in the red bone marrow.
There are several classifications of anemia depending on the causes, on the mechanisms of development of anemia and on the severity of changes in blood parameters. They are necessary for the doctor to understand what the current condition is connected with. This helps to choose the best tactics for further examination, to conduct a differential diagnosis and prescribe an effective treatment.
Anemia is diagnosed and treated by general practitioners, general practitioners, and family doctors. In the case of a severe or malignant course of the disease, the intervention of a hematologist may be required, as well as a more detailed and specialized examination.
There are many reasons for the development of anemia. Anemia is often a complication of an underlying chronic disease.
Iron deficiency anemia develops either when there is insufficient intake of iron in the body, or when the body has an increased need for iron.
Both factors are often present to varying degrees.
The causes of insufficient iron intake can be diseases of the gastrointestinal tract, in which the processes of digestion and absorption of food are disturbed. The use of foods containing low amounts of iron or iron in a form that is difficult to digest (only a plant-based diet). Some foods (alcohol, milk, coffee) or drugs (antibacterials, antacids) interfere with the absorption of iron from food.
The body’s need for iron (“iron consumption”) increases significantly in children during periods of active growth, in women during pregnancy and lactation.
Anemia often complicates the course of diseases accompanied by prolonged blood loss (especially against the background of malabsorption of food):
- peptic ulcer of the stomach and duodenum;
- inflammatory bowel disease;
- uterine fibroids, endometriosis;
- malignant neoplasms;
- blood clotting disorders;
- helminthic infestations.
The human body cannot synthesize iron! We get iron only from food. What matters is not only the amount of iron in foods, but also its availability for absorption by the body. Animal products (beef, lamb, liver) contain heme iron. It is absorbed by the body most effectively. Plant foods (vegetables, fruits, cereals) contain non-heme iron. The human body does not absorb non-heme iron well.
The main reason for the development of iron deficiency anemia, according to experts from the World Health Organization (WHO), is an unhealthy (unbalanced) diet. If you do not eat meat products, then you must remember that iron is absorbed much worse from vegetable products. Plan your diet wisely to prevent iron deficiency.
Improve iron absorption: - citrus fruits,
- wild rose,
- apples,
- sour berries,
- pumpkin,
- greenery,
- various types of cabbage.
Impair iron absorption: - milk and dairy products,
- tea,
- coffee,
- sesame,
- persimmon,
- alcohol,
- cocoa,
- chocolate,
- antibacterial and antacid drugs.
Another type of anemia is a disease caused by vitamin B12 deficiency.
B12 deficiency anemia develops due to a lack of cyanocobalamin.
Deficiency can be caused by:
- Insufficient intake of vitamin B12 from food (strict vegetarianism), since cyanocobalamin is found only in meat products, milk, eggs, fish and seafood.
- Violation of the secretion of the stomach “intrinsic factor Castle”;
- Malabsorption of vitamin B12 in the small intestine;
- Competitive consumption of vitamin B12;
- Increased consumption of vitamin B12;
- Decreased vitamin B12 stores;
- Violation of vitamin B12 transport;
- Absence of transcobalamin or the appearance of antibodies to it.
Symptoms of anemia:
- Paleness of the skin, cracks, “bites” in the corners of the mouth
- Brittle nails, thinning and striation of nails
- Hair loss, brittleness, structure disorder
- Increased fatigue, decreased performance
- Palpitations, dizziness, shortness of breath accompany even slight physical activity
Iron deficiency anemia is characteristic
- Taste perversion: addiction to inedible foods – raw meat, frozen semi-finished products; desire to eat inedible substances – chalk, earth, ice, clay.
- Perversion of the sense of smell: addiction to unpleasant odors, e.g. gasoline, acetone, paint, etc.
What tests can be done for those who suspect anemia? The most accessible and simplest is a complete blood count
- Complete blood count (without leukocyte formula and without ESR), venous blood.
If the analysis reveals changes in the number of erythrocytes, hemoglobin, hematocrit, erythrocyte indices (MCV, MCH, MCHC, RDW), then it is necessary to consult a doctor to prescribe further examination and treatment.
For reference:
Hematocrit (Ht) is an indicator that characterizes the number of cells per unit volume of whole blood. The value of hematocrit depends on the number and shape of red blood cells. A decrease in hematocrit also characterizes a decrease in the content of red blood cells in the blood.
MCV ( mean corpuscular volume) In the presence of long-term iron deficiency, maturing red blood cells become small, microcytes appear in the blood, and the MCV decreases. If there is a deficiency of vitamins B12 and B9maturing cells become large, macrocytes appear in the blood, and this indicator increases. Both conditions negatively affect the main function of red blood cells – the transport of oxygen and carbon dioxide. In the case of macrocytic anemia, their ability to pass through small-diameter vessels is reduced, and their life span is reduced.
MCH ( mean corpuscular hemoglobin) – the average content of hemoglobin in the erythrocyte, reflects the same processes as the previous MCV indicator. With a prolonged iron deficiency, erythrocytes enter the bloodstream, which, in the process of growth and maturation, lacked this microelement, and they become not only small, but also insufficiently saturated with hemoglobin. MCH begins to decrease, a state of hypochromia develops. Erythrocytes become pale, their functioning worsens. Previously, to assess the state of hemoglobin saturation of erythrocytes, a color indicator was calculated, MCH is its modern, more accurate analogue and allows differentiating anemia into normochromic, hypochromic and hyperchromic. In case of deficiency of vitamins B12 and B9the reverse situation occurs. Maturing erythrocytes are supersaturated with hemoglobin, this indicator begins to increase, a state of hyperchromia develops. Together, these two indicators will help the doctor only on the basis of the results of a general blood test to suggest the nature of anemia.
MCHC mean corpuscular hemoglobin Reflects the concentration of hemoglobin in the erythrocyte. It decreases with iron deficiency hypochromic anemia and diseases accompanied by impaired hemoglobin synthesis at any stage. Increases with hyperchromic B12 and B9deficiency anemia.
red blood cell distribution width This indicator depends on the average volume of the erythrocyte, therefore, with an increase or decrease in MCV, its increase is observed, which indicates in favor of the fact that there are cells of different volumes in the blood, for example, macrocytes and normocytes, or microcytes and normocytes.
For a comprehensive examination, when the cause of anemia is unknown, you can use the program Biochemical diagnosis of anemia, which includes parameters reflecting the metabolism and stock of iron in the body, the supply of vitamin B9(folic acid) and vitamin B12 (cyanocobalamin), as well as erythropoietin, a hormone that triggers erythropoiesis (the maturation of new red blood cells).
- Transferrin – carries out extracellular transport of iron to all cells of the human body.
- Soluble transferrin receptors (sTfR). One of the important diagnostic criteria, on the basis of which a true iron deficiency can be established. The entry of iron into the cell occurs after the interaction of the “iron-transferrin” complex with specific proteins – receptors on the cell membrane. The concentration of transferrin receptors depends on two factors – the amount of iron deposited in ferritin and the proliferative activity of the cell. The amount of soluble transferrin receptors is a sensitive indicator of both erythropoiesis activity and iron deficiency. With anemia that has developed as a complication of chronic diseases, this indicator does not change (remains normal). This helps to establish the underlying cause of the anemia.
- Ferritin (Ferritin) – a deposited form of iron, reflecting its total supply in the body. A decrease in the concentration of ferritin in the blood is a marker of iron deficiency states.
