Low blood pressure, also known as hypotension, is a condition in which a person’s blood pressure readings are lower than normal. Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps it around the body. Blood pressure is measured in millimeters of mercury (mmHg) and is expressed as two numbers, systolic pressure and diastolic pressure.
A normal blood pressure reading is around 120/80 mmHg. Blood pressure readings lower than 90/60 mmHg are considered low. However, it is important to note that low blood pressure can be normal for some people, particularly athletes and younger individuals. In these cases, low blood pressure is not a cause for concern.
Symptoms of Low Blood Pressure
Many people with low blood pressure do not experience any symptoms. However, some people may experience the following symptoms:
- Dizziness or lightheadedness
- Blurred vision
- Lack of concentration
Causes of Low Blood Pressure
Low blood pressure can be caused by a number of factors, including:
- Heart problems, such as a heart attack or heart failure
- Endocrine problems, such as diabetes or an underactive thyroid (hypothyroidism)
- Severe infections
- Blood loss
- Certain medications, such as diuretics, beta blockers, and some antidepressants
Treatment of Low Blood Pressure
Treatment for low blood pressure depends on the underlying cause. In many cases, no treatment is necessary as the condition improves on its own. However, if low blood pressure is causing symptoms, treatment may include:
- Drinking more fluids, especially water
- Eating a diet rich in salt
- Wearing compression stockings
- Taking medications to raise blood pressure, such as fludrocortisone
- Treating any underlying medical conditions
It is important to speak to a doctor if you are experiencing symptoms of low blood pressure. The doctor can determine the underlying cause and provide the appropriate treatment to alleviate symptoms and improve overall health.
