Low Blood Pressure

Overview

Low blood pressure is a condition in which the force of the blood pushing against the artery walls is too low. It's also known as hypotension. Blood pressure is measured in millimeters of mercury (mm Hg). In general, low blood pressure is a reading lower than 90/60 mm Hg.

Low blood pressure is a common condition that affects millions of people worldwide. It can be caused by various factors, including medical conditions, medications, and lifestyle habits. While low blood pressure might cause no symptoms that you notice, it can also lead to dizziness and fainting. In severe cases, low blood pressure can be life-threatening.

Types of Low Blood Pressure

There are several types of low blood pressure:

1. Orthostatic hypotension: This type of low blood pressure occurs when a person stands up suddenly.
2. Neurocardiogenic hypotension: This type of low blood pressure occurs when the nerves that control the heart and blood vessels are damaged.
3. Hypovolemic hypotension: This type of low blood pressure occurs when there is a sudden loss of blood or fluid.
4. Cardiogenic hypotension: This type of low blood pressure occurs when the heart is not pumping enough blood.

Causes of Low Blood Pressure

The causes of low blood pressure can vary depending on the type of hypotension:

1. Medical conditions: Certain medical conditions such as diabetes, kidney disease, and thyroid disease can cause low blood pressure.
2. Medications: Certain medications such as diuretics, beta-blockers, and calcium channel blockers can cause low blood pressure.
3. Lifestyle habits: Lack of physical activity, dehydration, and poor diet can contribute to low blood pressure.
4. Pregnancy: Pregnancy can cause low blood pressure due to changes in the circulatory system.

The following factors may increase the risk of developing low blood pressure:

1. Age: Older adults are more likely to develop low blood pressure due to age-related changes in the circulatory system.
2. Gender: Women are more likely to develop low blood pressure due to hormonal changes during pregnancy and menopause.
3. Family history: Having a family history of low blood pressure may increase the risk of developing the condition.
