What are the risks associated with a blood pressure of 86/46. How does low blood pressure affect the body. When does low blood pressure become an emergency. What are the symptoms of hypotension. How is low blood pressure diagnosed and treated.

Understanding Blood Pressure Readings: What Do the Numbers Mean?

Blood pressure is a crucial indicator of cardiovascular health, measured as two numbers: systolic and diastolic pressure. The reading 86/46 represents a blood pressure that is significantly lower than the normal range. But what exactly do these numbers signify?

• Systolic pressure (86): The force exerted on artery walls when the heart contracts
• Diastolic pressure (46): The pressure in the arteries when the heart is at rest between beats

A normal blood pressure typically falls between 90/60 mm Hg and 120/80 mm Hg. Any reading below 90/60 mm Hg is considered low blood pressure or hypotension. With a reading of 86/46, both the systolic and diastolic pressures are below the threshold for hypotension, indicating a potentially concerning situation.

The Implications of 86/46 Blood Pressure: When to Be Concerned

A blood pressure reading of 86/46 is significantly lower than what is considered normal. While some individuals may naturally have lower blood pressure without experiencing symptoms, for many, this level can be problematic. What are the potential consequences of such low blood pressure?

• Inadequate blood flow to vital organs
• Dizziness and fainting
• Fatigue and weakness
• Blurred vision
• Nausea
• Confusion

If you consistently have blood pressure readings around 86/46 and experience any of these symptoms, it’s crucial to consult a healthcare professional. They can determine the underlying cause and recommend appropriate treatment.

Common Causes of Low Blood Pressure

Understanding the potential causes of low blood pressure is essential for proper diagnosis and treatment. What factors can lead to a blood pressure as low as 86/46?

1. Dehydration
2. Blood loss
3. Certain medications (e.g., diuretics, beta-blockers)
4. Endocrine disorders (e.g., hypothyroidism, Addison’s disease)
5. Heart problems
6. Pregnancy
7. Severe allergic reactions (anaphylaxis)
8. Nutritional deficiencies

Identifying the underlying cause is crucial for effective treatment. A healthcare provider can conduct a thorough evaluation to determine the root of the problem and develop an appropriate treatment plan.

Types of Hypotension: Understanding Different Forms of Low Blood Pressure

Low blood pressure can manifest in various forms, each with its own characteristics and triggers. What are the main types of hypotension?

1. Orthostatic Hypotension

This type occurs when blood pressure drops suddenly upon standing up from a sitting or lying position. It’s common in older adults but can affect anyone who has been inactive for an extended period.

2. Postprandial Hypotension

Some individuals, particularly older adults, experience a drop in blood pressure after eating. This is due to blood flow being redirected to the digestive system.

3. Neurally Mediated Hypotension

This condition primarily affects children and young adults after standing for prolonged periods. It’s believed to be caused by miscommunication between the heart and brain.

4. Severe Hypotension

This dangerous form of low blood pressure can occur due to sudden blood loss, severe infections, or allergic reactions. It requires immediate medical attention.

Recognizing the Symptoms of Low Blood Pressure

Identifying the symptoms of low blood pressure is crucial for prompt intervention. What signs should you watch out for if you suspect your blood pressure might be as low as 86/46?

• Dizziness or lightheadedness
• Fainting (syncope)
• Blurred vision
• Nausea
• Fatigue
• Lack of concentration
• Cold, clammy skin
• Rapid, shallow breathing
• Depression

If you experience these symptoms, especially if they occur suddenly or frequently, it’s important to seek medical attention. A healthcare provider can assess your condition and determine if your symptoms are related to low blood pressure.

Diagnosing Low Blood Pressure: What to Expect

If you consistently have blood pressure readings around 86/46 or experience symptoms of hypotension, your healthcare provider will likely perform a series of tests to diagnose the condition and identify its underlying cause. What does the diagnostic process for low blood pressure typically involve?

1. Blood pressure measurements: Taken at different times and in different positions (lying down, sitting, standing)
2. Medical history review: Discussion of symptoms, medications, and lifestyle factors
3. Physical examination: To check for signs of dehydration, heart problems, or neurological issues
4. Blood tests: To check for anemia, blood sugar levels, and hormone imbalances
5. Electrocardiogram (ECG): To assess heart rhythm and function
6. Echocardiogram: To evaluate heart structure and function
7. Stress test: To observe blood pressure changes during physical activity
8. Tilt table test: To diagnose orthostatic hypotension

These diagnostic procedures help healthcare providers determine the severity of your condition and develop an appropriate treatment plan tailored to your specific needs.

Treatment Options for Low Blood Pressure

Managing low blood pressure often involves a combination of lifestyle changes and medical interventions. What are the primary treatment options for individuals with blood pressure as low as 86/46?

Lifestyle Modifications

• Increasing fluid and salt intake
• Wearing compression stockings
• Avoiding sudden position changes
• Eating smaller, more frequent meals
• Limiting alcohol consumption
• Exercising regularly

Medications

In some cases, medications may be prescribed to raise blood pressure. These may include:

• Fludrocortisone: To increase blood volume
• Midodrine: To tighten blood vessels and raise blood pressure
• Droxidopa: For neurogenic orthostatic hypotension

It’s important to note that treatment should always be supervised by a healthcare professional, as raising blood pressure too much can lead to other health complications.

When Low Blood Pressure Becomes an Emergency

While a blood pressure of 86/46 is concerning, it may not always constitute an emergency. However, there are situations where low blood pressure can become life-threatening. When should you seek immediate medical attention for low blood pressure?

• Severe chest pain
• Shortness of breath
• Sudden, severe headache
• Confusion or disorientation
• Seizures
• Prolonged loss of consciousness
• Signs of shock (cold, clammy skin, weak pulse, rapid breathing)

If you or someone around you experiences these symptoms, especially if accompanied by a blood pressure reading as low as 86/46, call emergency services immediately. Prompt medical intervention can be life-saving in such situations.

Preventing Low Blood Pressure: Strategies for Maintaining Healthy Blood Pressure

While some causes of low blood pressure are beyond our control, there are steps we can take to help maintain healthy blood pressure levels. What strategies can help prevent blood pressure from dropping to dangerous levels like 86/46?

1. Stay hydrated: Drink plenty of water throughout the day, especially in hot weather or during physical activity.
2. Eat a balanced diet: Ensure adequate intake of vitamins and minerals, particularly B12 and folic acid.
3. Limit alcohol consumption: Alcohol can lead to dehydration and lower blood pressure.
4. Exercise regularly: Physical activity helps improve circulation and heart health.
5. Manage stress: Practice relaxation techniques like meditation or deep breathing exercises.
6. Stand up slowly: Take your time when changing positions to avoid sudden drops in blood pressure.
7. Wear compression stockings: These can help improve blood flow in the legs.
8. Monitor your medications: Some medications can cause low blood pressure as a side effect. Discuss any concerns with your healthcare provider.

By implementing these strategies, you can help maintain a healthy blood pressure and reduce the risk of it dropping to concerning levels like 86/46.

Long-term Outlook for Individuals with Chronic Low Blood Pressure

For some individuals, a blood pressure of 86/46 may be a chronic condition. What is the long-term prognosis for people with persistently low blood pressure?

The outlook for individuals with chronic low blood pressure largely depends on the underlying cause and the presence of symptoms. For many people, low blood pressure doesn’t cause significant problems and may not require treatment. However, for those who experience symptoms or have an underlying health condition causing the low blood pressure, ongoing management may be necessary.

Potential Long-term Effects

• Increased risk of falls, especially in older adults
• Cognitive impairment due to reduced blood flow to the brain
• Cardiovascular complications
• Kidney problems

Regular medical check-ups and adherence to treatment plans are crucial for managing chronic low blood pressure and preventing potential complications. With proper care and management, many individuals with chronically low blood pressure can lead normal, healthy lives.

Special Considerations: Low Blood Pressure in Specific Populations

While a blood pressure of 86/46 is generally considered low for most adults, there are certain populations where the implications may differ. How does low blood pressure affect different groups?

Elderly Individuals

Older adults are more susceptible to orthostatic hypotension and may experience more severe symptoms from low blood pressure. They’re also at higher risk for falls and injuries related to sudden drops in blood pressure.

Pregnant Women

Blood pressure often decreases during pregnancy, especially in the first and second trimesters. While mild decreases are normal, severe hypotension can be dangerous for both mother and baby.

Athletes

Highly trained athletes often have lower resting blood pressure due to their efficient cardiovascular systems. For them, a reading of 86/46 might not be as concerning if they’re asymptomatic.

Individuals with Chronic Illnesses

People with conditions like Parkinson’s disease, diabetes, or heart problems may be more prone to low blood pressure and its complications. They require careful monitoring and management.

Understanding these population-specific considerations is crucial for healthcare providers in diagnosing and treating low blood pressure effectively.

The Role of Technology in Monitoring and Managing Low Blood Pressure

In today’s digital age, technology plays an increasingly important role in health management. How can technology assist individuals with blood pressure concerns, especially those dealing with readings as low as 86/46?

Home Blood Pressure Monitors

Digital blood pressure monitors allow for regular at-home monitoring, helping individuals track their blood pressure over time and detect any concerning trends.

Smartphone Apps

Various apps can help track blood pressure readings, medication schedules, and symptoms. Some even provide personalized advice based on the data entered.

Wearable Devices

Smartwatches and fitness trackers with blood pressure monitoring capabilities offer continuous monitoring and can alert users to sudden drops in blood pressure.

Telemedicine Platforms

These allow for remote consultations with healthcare providers, making it easier for individuals with chronic low blood pressure to receive regular check-ups and adjustments to their treatment plans.

While these technological tools can be valuable aids in managing low blood pressure, it’s important to remember that they should be used in conjunction with, not as a replacement for, professional medical care.

Coping Strategies for Living with Chronic Low Blood Pressure

Living with chronic low blood pressure, especially when it’s as low as 86/46, can be challenging. What strategies can help individuals cope with the day-to-day realities of this condition?

1. Educate yourself: Understanding your condition can help you manage it more effectively and reduce anxiety.
2. Plan your activities: Schedule more demanding tasks for times when your blood pressure is typically higher.
3. Prepare for symptoms: Keep a snack and water handy in case you feel faint or dizzy.
4. Communicate with others: Inform family, friends, and colleagues about your condition so they can offer support when needed.
5. Join support groups: Connecting with others who have similar experiences can provide emotional support and practical tips.
6. Practice stress management: Techniques like mindfulness and deep breathing can help manage stress, which can exacerbate symptoms.
7. Maintain a healthy lifestyle: Regular exercise, a balanced diet, and adequate sleep can help stabilize blood pressure.
8. Be prepared for emergencies: Wear a medical alert bracelet and keep emergency contact information readily available.

By implementing these coping strategies, individuals with chronic low blood pressure can improve their quality of life and manage their condition more effectively.

Future Directions in Low Blood Pressure Research and Treatment

As medical science advances, new insights and treatments for low blood pressure continue to emerge. What are some of the promising areas of research that could benefit individuals dealing with blood pressure as low as 86/46?

Novel Medications

Researchers are exploring new drugs that can raise blood pressure more effectively and with fewer side effects than current options.

Non-invasive Treatments

Studies are underway on non-pharmacological interventions, such as electrical stimulation techniques, to manage low blood pressure.

Artificial Intelligence in Diagnosis

AI-powered diagnostic tools are being developed to more accurately predict and diagnose various forms of hypotension.

Microbiome Research

Emerging evidence suggests a link between gut health and blood pressure regulation, opening up new avenues for treatment.

These advancements offer hope for improved management and treatment options for individuals dealing with chronic low blood pressure in the future.

When is Low Blood Pressure An Emergency?

A functional circulatory system is essential to your overall health and wellbeing.

More than 100,000 times a day, your heart pumps blood through a closed system of arteries, veins, and other blood vessels to the organs, tissues, and cells that make up your entire body.

Your blood picks up and distributes oxygen, nutrients, hormones, and other elements as it travels.

It also absorbs waste products and helps your body eliminate them. 

Blood pressure is a measurement that tells doctors how intensely your blood exerts force on the walls of your veins as your heart pumps blood through your circulatory system.

When you visit a healthcare provider, they record your blood pressure as two measurements: systolic blood pressure, the first number, and diastolic blood pressure, the second number. 

Systolic blood pressure is the amount of pressure in the arteries that your heart creates when it pumps and fills the arteries with blood.

Diastolic blood pressure is the amount of pressure in your veins when your heart is at rest.

Once doctors have both numbers, they can determine whether you have normal blood pressure, low blood pressure (hypotension), or high blood pressure (hypertension).

Blood pressure can change as you move through your day, but it can put you at risk for other serious health complications if it is chronically or excessively low or high.

Chronic low blood pressure can mean that your heart, lungs, brain, and other vital organs don’t receive enough blood to function correctly. 

If you have low blood pressure but don’t experience symptoms, your condition is not severe.

That said, for some people, low blood pressure can lead to feelings of dizziness, weakness, nausea, pale skin, vision changes, and other symptoms.

When someone experiences a sudden drop in blood pressure or has very low blood pressure, they may experience more severe symptoms like shock, low heart rate, shallow breathing, and clammy skin.  

In rare cases, low blood pressure can become a medical emergency.

If you are experiencing mental confusion, blue or pale skin, loss of consciousness, difficulty breathing, low pulse, or other severe symptoms, call 9-1-1 or go to your nearest emergency room for immediate medical attention. 

What is Low Blood Pressure (Hypotension)?

Blood pressure is the measurement that tells doctors about the force of blood in your circulatory system.

Your blood pressure reading is expressed as two numbers.

The first number, your systolic pressure, indicates how much pressure your heart creates when it beats, and your veins are full of blood.

The second number, your diastolic pressure, is the amount of pressure in your veins when your heart is at rest. 

Blood pressure can change throughout the day, depending on the person, physical activity, the stress they experience, and other factors. 

For most people, blood pressure levels remain within what doctors consider a “normal” range: 90/60 mm Hg and 120/80 mm Hg.

Anything higher than 120/80 mm Hg is elevated or high blood pressure (hypertension).

Anything lower than 90/60 mm Hg is low blood pressure (hypotension).

Four major types of low blood pressure are delineated based on the causes of low blood pressure, symptoms, and other factors. They include: 

• Orthostatic hypotension or postural hypotension: People with this condition experience a sudden drop in blood pressure when they stand up too quickly. It’s common in older adults but can affect younger people who have been sitting or squatting for a long time.

• Postprandial hypotension: People (mostly older adults) with this condition have a drop in blood pressure after they eat. It most commonly affects people with Parkinson’s disease and related disorders.

• Neurally mediated hypotension: Children and young adults experience this condition after standing for a long time. 

• Severe hypotension: People with this condition experience symptoms after a sudden and significant loss of blood, heart attack, infection, or allergic reaction.

Symptoms

Some people with chronic low blood pressure readings do not experience any symptoms.

In those cases, the condition may not require any treatment.

For others, however, low blood pressure can lead to severe symptoms or indicate an underlying problem.

Milder symptoms of low blood pressure include:

• Back pain 
• Blurry vision
• Confusion or difficulty concentrating.
• Dizziness
• Drowsiness
• Faded vision
• Feeling faint or lightheaded
• Headache
• Rapid or jumpy heartbeats

When blood pressure gets very low, very fast, your heart, brain, and other organs may not get the blood they need to function correctly, and you can go into shock.

Patients that have gone into shock may experience: 

• Clammy, blue, cold skin
• Rapid, shallow breathing 
• Sluggishness, sleepiness, or confusion
• Weak pulse or rapid pulse

Shock is a medical emergency and, in severe cases, can be fatal.

If you or someone you know has low blood pressure and is experiencing symptoms of shock, call 9-1-1 or go to the nearest emergency room immediately.

Causes

Patients can have or develop low blood pressure for many reasons.

Some people have naturally lower blood pressure than others.

As long as they don’t experience symptoms, doctors consider them healthy.

Specific health issues can cause low blood pressure for some patients.

The most common causes include:

• Adrenal insufficiency
• Age-associated blood pressure regulation decline
• Alcoholism
• A history of heart attack, heart failure, arrhythmias, or other heart problems
• Diabetes
• Heat exhaustion or heat stroke
• Hypothyroidism
• Lack of fluids (dehydration) 
• Liver disease
• Low blood sugar
• Nerve damage 
• Nutritional deficiencies like a lack of iron (anemia), folic acid, and vitamin B12
• Parathyroid disease
• Parkinson’s disease
• Pregnancy
• Severe allergic reactions (anaphylaxis)
• Severe blood loss from traumatic injury or internal bleeding 
• Severe infections (septicemia)

Some prescription medications, over-the-counter treatment options, and street drugs can also put patients at greater risk of developing low blood pressure. For example:

• Alpha-blockers and other high blood pressure medications
• Beta-blockers and other heart medications
• Erectile dysfunction medications 
• High blood pressure medications 
• Narcotics
• Tricyclic antidepressants 

When Hypotension is an Emergency

For most people, hypotension, or low blood pressure, is a condition that patients can manage with lifestyle changes and medicine.

However, in extreme cases, a patient with low blood pressure may develop severe symptoms that require immediate medical attention.

Underlying Conditions

Sometimes, low blood pressure can indicate the presence of severe conditions that are dangerous or even life-threatening.

For example, patients experiencing a heart attack or heart failure can develop low blood pressure, as can people with severe infections.

A severe allergic reaction or anaphylactic shock is one of the causes of low blood pressure.

Those who experience a loss of significant blood volume due to traumatic injury, burn, or internal bleeding can also develop symptoms of low blood pressure as a result.

If you are experiencing chest pain, rapid or shallow breathing, loss of consciousness, or seeing a blue tinge on your skin, these could be signs that you need immediate medical attention.

Call 9-1-1 or go to your nearest emergency room.

Sudden drops

Even when it’s small, a sudden drop in blood pressure can be a serious health problem.

If blood pressure drops sharply, the brain doesn’t receive enough blood to function correctly.

Even a drop of 20 mm Hg within a few minutes can cause dizziness, lightheadedness, and other uncomfortable symptoms. 

Risks of low blood pressure 

Patients can experience dizziness, fainting, and falls, a dangerous complication for older adults.

In serious cases, severe drops in blood pressure can decrease the blood flow to the heart and brain so much that they damage the organ’s ability to function.

Severe hypotension has been linked to stroke, shock, and cardiovascular issues.

When to Go to the ER

Low blood pressure can be a serious, even life-threatening condition.

If you or someone you know is experiencing extreme symptoms, call 9-1-1 or go to your nearest emergency room for treatment right away. 

Emergency symptoms may include: 

• Cold, clammy, or sweaty skin 
• A bluish tint to the skin 
• Chest pain
• Rapid breathing 
• Shallow breathing 
• Vision changes 
• Confusion 
• Loss of consciousness

If you experience symptoms after taking medication or have been diagnosed with low blood pressure and are experiencing an increased frequency in even mild symptoms, call your doctor to discuss your condition and next steps.

How to Treat Hypotension

If you have low blood pressure that doesn’t cause symptoms or only occasionally causes mild lightheadedness, you may not need to treat your condition.

If you have more significant symptoms, your doctor might suggest several lifestyle and medication changes for you to use to regulate your blood pressure better and improve your overall health and wellbeing.

Lifestyle changes

There are a few changes you can make to reduce the signs and symptoms of low blood pressure. They include: 

• Eating more salt: Increasing dietary sodium may help raise your blood pressure and keep it more regulated. 

• Drinking water: Increasing your intake of fluids can increase the blood you have in your body and help raise your blood pressure.

• Avoiding alcoholic beverages: Alcohol lowers blood pressure and should be avoided by patients who struggle with symptoms. 

• Eating small meals: Enjoying smaller meals more frequently can help you avoid the extreme eating-associated changes in blood pressure that can occur with heavier meals.

• Wearing compression socks or elastic abdominal binders: Compression socks and abdominal binders are designed to maintain blood flow and reduce swelling, which can help address the root cause of postural hypotension.

• Move slowly: Changing posture positions quickly can lead to drops in blood pressure. Avoid sitting or standing up too suddenly.

Medication changes

If you have made lifestyle changes and still experience symptoms related to low blood pressure, talk to your doctor about medication changes you can make to regulate your circulatory system better. 

Medications that can help address low blood pressure include: 

• Fludrocortisone (Florinef)
• Midodrine (Orvaten)

If you have been prescribed a medication that puts you at risk for low blood pressure, or if you experience symptoms like lightheadedness or feeling faint after taking a medication, talk to your doctor about switching to a treatment option that you can better tolerate.

What Causes It and When It’s Dangerous

• Low blood pressure is defined by a blood pressure reading of 90/60 mm Hg or lower.
• Low blood pressure with no symptoms is rarely a cause for concern. 
• If you also experience dizziness, shortness of breath, or fainting, seek medical attention. 

Blood pressure is a measure of the force of blood moving through your artery walls. When that force is too low, your vital organs may not be getting the right amount of blood flow they need to function. 

Here’s what you need to know about what might cause low blood pressure and when it is considered an emergency.

What low blood pressure means

Hypotension is the medical term for low blood pressure, which is typically defined by a blood pressure reading of 90/60 mm Hg or lower. For reference, a normal blood pressure range is around 100/60 mm Hg to 120/80 mm Hg. 

Low blood pressure with no symptoms is rarely a cause for concern, says Nicole Weinberg, MD, a cardiologist at Providence Saint John’s Health Center. In fact, some people have chronic low blood pressure, but feel fine, and do not need to be treated. 

However, if low blood pressure is combined with symptoms of dizziness, fainting, shortness of breath, or lightheadedness, it could be a sign that you need medical attention.

What causes low blood pressure

The exact cause of low blood pressure is not always clear, Weinberg says, but some common causes include: 

• Side effects from over-the-counter or prescription medications, including drugs used to treat high blood pressure, like diuretics, as well as tricyclic antidepressants and erectile dysfunction drugs
• Pregnancy (often in the first 24 weeks), due to hormonal changes and expansion of the circulatory system 
• Other hormone changes, including issues with the hormone-producing glands in the endocrine system 
• Dehydration, heat exhaustion, or heat stroke

In addition, postural or orthostatic hypotension can occur when you quickly rise from a sitting or lying down position, causing a sudden drop in blood pressure and feelings of lightheadedness. This can last for just a few minutes or it can be more severe and cause fainting. 

In fact, Parkinson’s disease can impair the body’s ability to automatically adjust blood pressure when changing positions, resulting in bouts of orthostatic hypotension. About one in five people with Parkinson’s are affected by orthostatic hypotension. 

Weinberg says orthostatic hypotension usually isn’t a medical emergency unless it persists and you consistently feel lightheaded when you stand.

For someone experiencing an isolated episode of hypotension, Weinberg advises lying down, eating a salty snack, and drinking water — since fluids increase blood volume and can help get your blood pressure back to normal. 

When low blood pressure is an emergency 

If you frequently experience symptoms of low blood pressure, such as dizziness or fainting spells, you should consult a doctor. While low blood pressure, itself, usually isn’t fatal, there are serious medical situations where it is considered an emergency, and you should go to the hospital.  

“The likelihood of dying from low blood pressure is low unless it is related to another disease process,” Weinberg says.

For example, a blood infection, or sepsis, can result in low blood pressure. Sepsis occurs when the chemicals released by the body to fight an infection trigger widespread inflammation, resulting in blood clotting that reduces blood flow to vital organs, such as your heart, kidneys, and brain. This can progress to septic shock and very low blood pressure, which may be fatal, and should be treated immediately. 

Low blood pressure can also be affiliated with Addison’s disease — a disorder in which the adrenal glands do not produce enough cortisol, a hormone that helps your body respond to stress. Lack of cortisol production can cause addisonian crisis, which is characterized by low blood pressure and can be fatal without proper treatment.  

The treatment for low blood pressure varies depending on the cause. In severe cases, someone might need intravenous therapy (IV) to deliver fluids into the veins and raise blood pressure. In critical situations, such as septic shock, doctors may use drug therapies either orally or through an IV to quickly raise blood pressure. 

Insider’s takeaway

Low blood pressure, or hypotension, is often not a cause for concern. However, if it accompanies symptoms like fainting, shortness of breath, lightheadedness, or dizziness, you may need medical attention.

Some common causes of low blood pressure include pregnancy, hormonal changes, dehydration, and medication side effects. 

Low blood pressure alone is not considered fatal, but there are some conditions where it’s an emergency. Low blood pressure caused by Sepsis or Addison’s disease calls for immediate medical treatment.

Low blood pressure – Hypotension, how to increase blood pressure? – Health World

What is low blood pressure?

Normal blood pressure ranges from 90/60 to 120/80 mmHg. If the pressure readings are less than 90/60, the pressure is considered low. This condition is called hypotension.

Each person has his own normal (working) pressure, so hypotension is usually called pressure, which is 20% lower than the working one. Many (most often thin women) live with hypotension for years and feel great. Doctors believe that these people are lucky – they are less likely to suffer from cardiovascular diseases.

Symptoms of low blood pressure

• Headache in the temples, sometimes headache in the back of the head or in the forehead is the most common symptom of low blood pressure. This symptom is directly related to circulatory disorders of the cerebral vessels.
• Dizziness, both sudden and after a sudden change in body position, especially in the morning, are also characteristic symptoms of low blood pressure. Usually dizziness is accompanied by darkening of the eyes, noise in the head, sometimes even fainting. Therefore, people with low blood pressure are not recommended to get out of bed abruptly.
• Feeling of weakness, fatigue, inactivity. Such people get tired very quickly, this is especially acute at the end of the working day – attention and memory decrease, the person becomes absent-minded, irritable, and he has mood swings. It is very difficult for them to be in the same position for a long time, for example, standing in line or washing dishes.
• Hypotension is often accompanied by vegetative disorders – sweating of the palms and feet, violations of thermoregulation – a decrease in temperature to 35.8 – 36 C, sometimes there may be a feeling of incomplete inspiration or shortness of breath during physical exertion.

What to do with low pressure?

If your blood pressure is consistently low but you feel good, there is no need to do anything. If you are concerned about nausea, dizziness or fainting, you need to consult a general practitioner in St. Petersburg.
The frequent occurrence of low blood pressure symptoms may indicate the presence of various diseases. In order to identify the cause, doctors conduct various examinations: ultrasound of the heart, blood vessels, ECG, FGDS. The therapist can refer to narrow specialists: a cardiac surgeon, a gastroenterologist, an endocrinologist, a neurologist. It is important to find out the true cause, because the method of treatment depends on the diagnosis.

General recommendations for hypotension:

• Drink plenty of fluids and salt. In summer, a person quickly loses water and minerals.
• Drink coffee, tea or cocoa. Drinks with caffeine give a good effect, though short-term.
• Avoid stuffiness, extreme stress or fright.
• Maintain a good mood.
• Perform simple exercises that are useful for hypotension: sit in a cross-legged position, clench and unclench your fists, work with a manual expander.

What to do if there is a sudden drop in pressure?

First, you need to take a supine position. If there is no way to lie down, you must definitely sit down and tilt your head as low as possible, between your knees. This position will ensure the flow of the required amount of blood to the brain and well-being will immediately improve.

Secondly, you should immediately drink a glass of water or, best of all, strong sweet tea. When fainting, you can revive him with a bottle of essential oils or ammonia. It is necessary to bring the bottle to the nose and lightly smear the whiskey. These measures will help in the shortest possible time to normalize blood pressure and bring a person back to normal.

Consequences of low blood pressure

• In children and adolescents, hypotension often occurs due to rapid growth, a malfunction occurs in the autonomic nervous system.

Blood pressure is one of the most important indicators of health, depending mainly on vascular tone and the volume of circulating blood. Everyone knows about the dangers of high blood pressure. What do doctors say about low?

The normal level of pressure at any age is less than 140/90 mm Hg. Art. An increase in blood pressure above 140/90 mm Hg. Art. called arterial hypertension, or hypertension. This condition is dangerous for the development of strokes, heart attacks and other cardiovascular complications, requires treatment and medical supervision even if you do not feel it. What can be said about low blood pressure?

Hypotension (lower than 90/60 blood pressure) is usually not a health hazard. Constantly lowered blood pressure numbers often occur in young girls of a fragile physique, but this, as a rule, does not affect the quality of life.

Permanent hypotension in good health does not require treatment. But, if the pressure dropped sharply and this led to fainting or caused a pre-fainting state, medical assistance and additional examination may be required.

Particular attention should be paid to lowering blood pressure in the following situations:

Orthostatic hypotension is a loss of consciousness with a sharp change in body position from horizontal to vertical, for example, when getting up from a bed. Because of this, the volume of circulating blood is redistributed and the blood supply to the brain is temporarily reduced. Often this condition occurs in pregnant women due to changes in the circulatory system and a shift in the center of gravity. Therefore, during pregnancy, it is important to avoid sudden movements and carefully get out of the car or get up from the chair.

Taking drugs to lower blood pressure. The goal of antihypertensive therapy is to achieve a sustained reduction in blood pressure below 140/90 mmHg. st, but without episodes of a sharp decline. Inappropriate dosage of the drug can cause hypotension – this leads to weakness, fatigue during exercise and dizziness. In this case, it is necessary to conduct daily monitoring of blood pressure and adjust therapy.

Fainting is a short-term loss of consciousness due to impaired blood supply to the brain. For a complete loss of consciousness, a sudden cessation of cerebral blood flow for 6–8 seconds is sufficient.

Types of fainting:

• reflex, from fear, pain, heat or stuffiness;
• orthostatic, with a sharp transition to a vertical position;
• cardiogenic, in diseases of the heart or blood vessels, as well as due to cardiac arrhythmias.

After a sudden loss of consciousness, especially if this is a repeated case, you need to seek medical help. You may need to consult a therapist, cardiologist, neurologist. In addition, it is important to undergo examinations: Holter monitoring, record an ECG and conduct an MRI of the brain. And also examine the level of sugar, iron and thyroid hormones.

Prevention of a sharp drop in blood pressure

Avoid situations that provoke a decrease in pressure (do not get out of bed abruptly, try to avoid stuffy and hot rooms, as well as stress).

A quick intake of cold water can also prevent orthostatic hypotension (fainting with a sudden change in body position).

Simple exercises such as crossing the legs, clenching the hand into a fist can help to quickly and effectively increase blood pressure and prevent fainting.

Tilt training—regular training that mimics getting up from a prone position in young people with recurrent syncope can significantly reduce the incidence of hypotensive conditions.

First aid for fainting

With a sharp drop in blood pressure, you need to lie down, raise your legs higher and open a window to increase oxygen access and, if possible, drink water.

To maintain a normal level of blood pressure at any age, the following are important: constant physical activity, sufficient fluid intake and a balanced diet. It is important to remember that normal pressure numbers are less than 140/90 mmHg Art.
