What is the cause of low blood pressure

Hypotension refers to blood pressure below the normal range, typically with systolic blood pressure below 90mmHg or diastolic blood pressure below 60mmHg. The causes of hypotension include genetic, environmental, physiological, traumatic, and pathological factors. For low blood pressure, it can be improved by adjusting lifestyle, medication treatment, and dietary adjustments.

1. Genetic factors: Hypotension may be related to familial inheritance. If there is a history of low blood pressure in the family, the individual's risk of developing low blood pressure will increase. It is recommended to regularly monitor blood pressure and conduct health management under the guidance of a doctor.

2. Environmental factors: Long term exposure to high temperatures, high altitudes, or low oxygen environments may lead to a decrease in blood pressure. It is recommended to avoid prolonged exposure to extreme environments, replenish water and electrolytes appropriately, and maintain body balance.

3. Physiological factors: People who are older, underweight, or physically weak are more likely to experience low blood pressure. Elderly people are prone to orthostatic hypotension due to decreased vascular elasticity and weakened ability to regulate blood pressure. It is recommended to enhance physical fitness through moderate exercise, such as walking, yoga, etc., while avoiding sudden changes in posture.

4. Trauma: Severe trauma or excessive blood loss may lead to acute hypotension or even shock. At this point, it is necessary to seek medical attention immediately, replenish fluids and blood, and perform surgical treatment if necessary, such as blood transfusion, hemostasis, etc.

5. Pathological factors: Certain diseases such as hypothyroidism, adrenal insufficiency, heart disease, or severe infections may cause hypotension. Treating the underlying disease is key, for example, hypothyroidism can be improved by taking thyroid hormone drugs, and heart disease patients need to use antihypertensive or cardiotonic drugs according to their condition. Dietary regulation can also help improve low blood pressure. Suggest increasing salt intake and consuming salted vegetables, nuts, etc. in moderation; Drink plenty of water to keep your body hydrated; Consuming foods rich in iron and vitamin B12, such as red meat, eggs, and green leafy vegetables, to improve low blood pressure caused by anemia. The causes of hypotension are complex and diverse, and targeted treatment is needed according to the specific situation. Regular physical examinations, monitoring of blood pressure changes, and timely adjustment of lifestyle and dietary habits are important measures for preventing and managing low blood pressure. If symptoms such as dizziness and fatigue occur, seek medical attention promptly, identify the cause, and receive professional treatment.
