Low Blood Pressure Treatment in Delhi, India

Low blood pressure (BP), medically referred to as hypotension, occurs when an individual's blood pressure falls below the normal range. While high blood pressure receives significant attention, it's crucial to understand that low BP can also impact one's health.

It can happen either as a condition on its own or as a symptom of a wide range of conditions. It may not cause symptoms. But when it does, you may need medical attention. Normal blood pressure ranges between 90/60 mm Hg and 120/80 mm Hg.

Types of Hypotension

1. Absolute hypotension

Your resting blood pressure is below 90/60 mm of mercury (mm Hg).

2. Orthostatic hypotension (Postural hypotension)

Your blood pressure stays low for longer than three minutes after you stand up from a sitting position. (It’s normal for your blood pressure to drop briefly when you change positions, but not for that long.) The drop must be 20 mm Hg or more for your systolic (top) pressure and 10 mm Hg or more for your diastolic (bottom) pressure.

How Common is Low Blood Pressure?

Because low blood pressure is common without any symptoms, it’s impossible to know how many people it affects. However, orthostatic hypotension seems to be more and more common as you get older. An estimated 5% of people have it at age 50, while that figure climbs to more than 30% in people over 70.

Who Does Low Blood Pressure Affect?

Hypotension can affect people of any age and background, depending on why it happens. However, it’s more likely to cause symptoms in people over 50 (especially orthostatic hypotension). It can also happen (with no symptoms) to people who are very physically active, which is more common in younger people.

Low Blood Pressure Causes

Understanding the underlying causes of low blood pressure is crucial for effective management. It's important to note that hypotension can be a symptom of an underlying medical condition or a result of various external factors.

Several medical conditions can contribute to low blood pressure. These include:

• Dehydration: Dehydration is one of the most common causes of temporary low blood pressure. When the body lacks sufficient fluids, blood volume decreases, leading to a drop in blood pressure. Dehydration can be a result of inadequate fluid intake, excessive sweating, vomiting or diarrhoea.
• Heart problems: Cardiac issues, such as bradycardia (slow heart rate), heart valve problems and heart failure, can lead to low blood pressure. In these cases, the heart may not pump blood effectively, causing a decrease in blood pressure.
• Neurological disorders: Conditions such as Parkinson's disease and multiple system atrophy can interfere with the autonomic nervous system's control over blood pressure.
• Pregnancy: Blood pressure tends to decrease during the early stages of pregnancy but typically returns to normal as the pregnancy progresses.

• Medications: Certain medications can lower blood pressure as a side effect. Common culprits include diuretics (water pills), alpha-blockers, beta-blockers, and some antidepressants.

• Diet: A diet that is too low in salt (sodium) may contribute to hypotension, as sodium helps regulate blood volume and pressure. It's important to strike a balance; excessive salt intake can lead to high blood pressure.
• Posture changes: For individuals prone to orthostatic hypotension, adopting careful posture changes can be helpful. This includes standing up slowly from a seated or lying position to allow the body time to adjust to changes in blood pressure.

Low Blood Pressure Symptoms

Low blood pressure symptoms include:

• Dizziness or feeling lightheaded
• Fainting or passing out (syncope)
• Nausea or vomiting
• Distorted or blurred vision
• Fast, shallow breathing
• Fatigue or weakness
• Feeling tired, sluggish or lethargic
• Confusion or trouble concentrating
• Agitation or other unusual changes in behavior (a person not acting like themselves)

For people with symptoms, the effects depend on why hypotension is happening, how fast it develops and what caused it. Slow decreases in blood pressure happen normally, so hypotension becomes more common as people get older. Fast decreases in blood pressure can mean certain parts of your body aren’t getting enough blood flow. That can have effects that are unpleasant, disruptive or even dangerous.

These symptoms can vary among different age groups. In older adults, it often presents as dizziness, weakness and unsteadiness, increasing the risk of falls. Younger individuals may experience symptoms like fatigue and fainting during sudden posture changes. While the symptoms of hypotension can differ across age groups, monitoring and addressing the condition are crucial for maintaining overall health and well-being.

What Are the Possible Signs of Low Blood Pressure?

Your healthcare provider may observe these signs of low blood pressure:

• A heart rate that’s too slow or too fast.
• A skin color that looks lighter than it usually does.
• Cool kneecaps.
• Low cardiac output (how much blood your heart pumps).
• Low urine (pee) output.

Low Blood Pressure Diagnosis And Tests

How is Low Blood Pressure Diagnosed?

Hypotension itself is easy to diagnose. Taking your blood pressure is all you need to do. But figuring out why you have hypotension is another story. If you have symptoms, a healthcare provider will likely use a variety of tests to figure out why it’s happening and if there’s any danger to you because of it.

What Tests Will Be Done to Diagnose Low Blood Pressure?

Your provider may recommend the following tests:

• Lab testing to exclude : Diabetes, Vitamin deficiencies, Thyroid or hormone problems, Low iron levels (anemia).
• Imaging: If providers suspect a heart or lung problem is behind your hypotension, they’ll likely use imaging tests to see if they’re right. These tests include ECG, Exercise stress testing, Echocardiaogram, Tilt Table Test ( to help diagnose orthostatic hypotension)

Low Blood Pressure Treatment

The treatment and management of low blood pressure depend on its underlying cause, severity, and the presence of symptoms. Treatment goals typically include alleviating symptoms, addressing the root cause, and preventing complications.

Increase salt intake

Increasing dietary salt (sodium) intake can help raise blood pressure, particularly in cases where salt depletion is a contributing factor. However, it's essential to consult with a healthcare provider before significantly altering salt intake, as excessive sodium consumption can lead to other health problems, such as high blood pressure.

Stay hydrated

Maintaining proper hydration is crucial for preventing and managing low blood pressure. Individuals should aim to drink an adequate amount of fluids throughout the day, especially if they're in a hot climate or engaging in physical activity.

Regular exercise

Engaging in regular physical activity can help improve cardiovascular health and contribute to better blood pressure control. Aerobic exercises like brisk walking, swimming and cycling are excellent choices. However, individuals with severe hypotension should consult their healthcare provider before starting a new exercise regimen.

Elevate the head of the bed

For individuals prone to orthostatic hypotension, raising the head of the bed by a few inches can reduce the likelihood of symptoms upon waking.

Medications

In cases where lifestyle changes alone are insufficient to manage low blood pressure, healthcare providers may prescribe medications to raise blood pressure. The choice of medication depends on the underlying cause and the individual's specific needs. Some common classes of medications used to treat hypotension include Fludrocortisone, Midodrine

Regular monitoring

Individuals with low blood pressure should monitor their blood pressure regularly, especially if they are on medication. This can help track any changes and ensure that blood pressure remains stable.

Recognising triggers

Identifying and avoiding triggers that worsen low blood pressure is essential. For example, individuals prone to orthostatic hypotension should take care when changing positions, rising slowly from a seated or lying position to prevent sudden drops in blood pressure.

Low Blood Pressure Complications and Risks

Low blood pressure, if left unmanaged, can lead to various complications and risks, affecting overall health and well-being.

• Falls and fall related injuries: One of the primary risks associated with hypotension, especially in older adults, is an increased likelihood of falls and injuries. Sudden drops in blood pressure can result in loss of balance and falls, which may lead to fractures or other injuries.
  • Falls and fall-related injuries: These are the biggest risks with hypotension because it can cause dizziness and fainting. Falls can lead to broken bones, concussions and other serious or even life-threatening injuries. If you have hypotension, preventing falls should be one of your biggest priorities.
  • Shock: When your blood pressure is low, that can affect your organs by reducing the amount of blood they get. That can cause organ damage or even shock (where your body starts to shut down because of limited blood flow and oxygen).
• Heart problems or stroke: Low blood pressure can cause your heart to try to compensate by pumping faster or harder. Over time, that can cause permanent heart damage and even heart failure. It can also cause problems like deep vein thrombosis (DVT) and stroke because blood isn’t flowing like it should, causing clots to form.
• Fainting spells : Pregnant women may experience hypotension, particularly in the early stages of pregnancy, due to hormonal changes and the expansion of blood vessels, which can result in symptoms like lightheadedness and fainting. While typically not life-threatening, fainting can be dangerous if it occurs in situations where injury may result, such as while driving.
• Cognitive impairment : Severe hypotension can impair brain function, leading to cognitive issues such as confusion and difficulty concentrating. These symptoms can significantly affect daily life and overall quality of life.

Low Blood Pressure Prevention

• Avoid prolonged standing: If someone is prone to orthostatic hypotension, avoid prolonged periods of standing, especially in one position. Take breaks and change their position to prevent symptoms.
• Wear compression stockings: Compression stockings or socks can help improve blood circulation in the legs and reduce the risk of orthostatic hypotension. Consult the healthcare provider for guidance on selecting and using compression garments.
• Dietary recommendations: A well-balanced diet rich in nutrients is essential for overall health and blood pressure regulation. While reducing salt intake can be helpful for some, it's important not to eliminate salt entirely, as it plays a crucial role in maintaining blood volume and pressure. Focus on a diet that includes:
• Fruits and vegetables: These provide essential vitamins and minerals that support cardiovascular health.
• Whole grains: Opt for whole grains like brown rice, whole wheat bread and oats, which offer fibre and nutrients.
• Lean proteins: Incorporate lean protein sources like poultry, fish and legumes into your diet.
• Healthy fats: Include sources of healthy fats such as avocados, nuts and olive oil.
• Moderate salt: Use salt in moderation to avoid excessive sodium intake.
• Adequate fluids: Drink enough water and fluids to stay well-hydrated.
• Exercise and its impact on blood pressure: Regular exercise, such as aerobic activities like brisk walking or cycling, can have a positive impact on blood pressure by helping to lower it over time. This is often attributed to exercise's ability to improve cardiovascular health, increase blood vessel flexibility and promote weight management, all of which contribute to better blood pressure control.

When to Consult a Healthcare Professional

Understanding when to seek medical advice for low blood pressure is essential for timely diagnosis and appropriate management. While mild episodes of hypotension may not always require medical intervention, certain signs and situations warrant prompt attention from a healthcare professional.

• Persistent symptoms: If someone experiences persistent symptoms of low blood pressure, such as dizziness, lightheadedness, fainting, fatigue or blurred vision, it's crucial to consult a healthcare provider. These symptoms may indicate an underlying issue that requires evaluation and treatment.
• Severe symptoms: Severe symptoms of low blood pressure, including sudden and significant drops in blood pressure, loss of consciousness or chest pain, require immediate medical attention. These symptoms may be indicative of a medical emergency.
• Frequent fainting spells: Frequent syncope episodes should be evaluated by a healthcare provider to determine the underlying cause and develop an appropriate management plan.
• Changes in medication: If someone is taking medications that can lower blood pressure, such as diuretics or antihypertensive drugs, and notice significant changes in the blood pressure readings or experience new symptoms, they must contact a healthcare provider. Adjustments to the medication regimen may be necessary.
• Underlying health conditions: Individuals with underlying medical conditions known to affect blood pressure, such as heart problems, diabetes or hormonal disorders, should regularly consult with their healthcare provider to monitor blood pressure and manage their condition effectively.
• Pregnancy: Pregnant women experiencing low blood pressure should consult their obstetrician or healthcare provider for guidance. While some blood pressure changes are normal during pregnancy, it's essential to ensure that blood pressure remains within a safe range for both the mother and the baby.
• Elderly individuals: Older adults are more susceptible to low blood pressure, and any significant changes in blood pressure readings or symptoms should be promptly evaluated by a healthcare provider. Falls and injuries resulting from hypotension can be particularly concerning for this age group.
• Routine check-ups: Even if one does not experience symptoms of low blood pressure, it's advisable to schedule routine check-ups with their healthcare provider. Regular monitoring can help detect and manage any potential blood pressure issues before they become problematic.
