Low Blood Pressure (Hypotension): Symptoms, Causes & Remedies

Blood pressure under 90/60 mm/Hg is referred to as hypotension or low blood pressure. It frequently has no symptoms in affected individuals. However, they are typically uncomfortable or unpleasant when lightheadedness, dizziness, and other symptoms appear. In some circumstances, hypotension can be harmful; prompt diagnosis and treatment are crucial.

In some instances, natural remedies can boost low blood pressure and reduce some of the symptoms. However, in some situations, therapy and medication may be required as an intervention to elevate blood pressure to a healthy level.

Types

Hypotension can occur in different forms depending on the cause and how it affects blood pressure levels. The main types include:

• Absolute Hypotension: Your resting blood pressure is less than 90/60 millimeters of mercury (millimeters of mercury).
• Orthostatic Hypotension: Three minutes after getting out of a sitting position, you experience orthostatic hypotension, which is a dip in blood pressure. Your systolic (top) pressure must decrease by at least 20 mmHg, and your diastolic (bottom) pressure must drop by at least 10 mmHg. Postural hypotension is another name for this since it occurs when a person’s posture shifts.

What Distinguishes Hypotension from Hypertension?

Hypertension, also known as high blood pressure, happens when the blood consistently exerts excessive force against the artery walls. It may result in severe health problems like heart disease, stroke, and kidney damage, typically showing no clear symptoms, which is why it’s often called the “silent killer.”

Hypotension, or low blood pressure, is when readings fall below 90/60 mm Hg. A sudden drop can cause dizziness or fainting, and extreme drops may lead to life-threatening conditions like shock. Though less common than hypertension, hypotension can still pose significant health risks if it reduces blood flow to vital organs.

Symptoms

Symptoms of low blood pressure (hypotension) include:

• Blurred eyesight
• Unsteadiness or faintness
• Fatigue
• Difficulty focusing
• Nausea

An unexpected drop in blood pressure, especially when symptoms are present, can signal an underlying health condition in some individuals. It can be harmful when blood pressure suddenly drops. Even a slight change in blood pressure, for example, from 110 mm Hg to 90 mm Hg, can lead to dizziness and fainting. Significant drops in blood pressure, such as those triggered by severe bleeding, major infections, or allergic reactions, can be life-threatening.

A dangerously low drop in blood pressure can trigger a medical emergency called shock. Shock symptoms include:

• Confusion, particularly in the elderly
• Clammy, frigid skin
• Decrease in skin color (pallor)

Causes

Many different factors can cause hypotension.

• Orthostatic hypotension occurs when you get up too rapidly, and your body cannot make up for it by increasing the blood supply to your brain.
• Disorders of the central nervous system: Parkinson’s disease, for example, can alter how your neurological system regulates your blood pressure. Given that their digestive systems consume more blood when processing food, people with these illnesses who have hypotension may experience the symptoms of low blood pressure after eating.
• Low blood volume: Low blood pressure can result from extensive bleeding after an injury. Low blood volume can also be a result of dehydration.
• Lung and heart problems: Hypotension can occur when your heart beats too quickly or too slowly, or if your lungs aren’t functioning properly.
• Medicines on prescription: Medication for high blood pressure, heart failure, erectile dysfunction, neurological issues, depression, and other conditions can cause hypotension.
• Extreme temperatures: Hypotension can be impacted by extreme temperatures and aggravate its consequences.

Conditions That May Result in Low Blood Pressure

The following medical problems can result in low blood pressure:

• Pregnancy: Pregnancy-related changes can cause blood vessels to expand rapidly. The changes might lower blood pressure. Low blood pressure is typical early in pregnancy (the first 24 weeks), and low blood pressure is typical. After giving birth, blood pressure typically recovers to pre-pregnancy levels.
• Conditions of the heart and heart valves: A heart attack, heart failure, valve disorders, or an unusually slow heartbeat (bradycardia) can all lead to low blood pressure.
• Illnesses relating to hormones (endocrine disorders): Conditions affecting the adrenal or parathyroid glands, like Addison’s disease, can cause a drop in blood pressure. In addition, hypoglycemia, diabetes, and other conditions can drop blood pressure.
• Dehydration: The body’s blood volume reduces when there is insufficient water. Blood pressure may decline as a result of this. Dehydration is a risk factor for fever, vomiting, severe diarrhoea, the use of diuretics, and vigorous activity.
• Loss of blood: Significant blood loss from an injury or internal bleeding reduces blood volume, leading to a sudden drop in blood pressure.
• A serious infection (septicemia): When an infection spreads into the bloodstream, it can cause septic shock—a dangerous and potentially fatal drop in blood pressure.
• Severe allergic response (anaphylaxis): One of the key symptoms of a severe allergic reaction is a sudden and substantial drop in blood pressure.
• Nutritional deficiency in the diet: Deficiencies in iron, folate, and vitamin B-12 can hinder red blood cell production, leading to anemia and a drop in blood pressure.

Natural & Home Remedies

Most people cannot recognise that they have low blood pressure. However, if you have common blood pressure symptoms, you can try the following home remedies for hypotension.

• Increase your salt intake
• Drink more water
• Sit cross-legged
• Tulsi Leaves
• Almond Milk
• Drink beetroot and carrot juice
• Increase vitamin intake
• Coffee
