How to prevent the causes and hazards of low blood pressure

Low blood pressure may be caused by dehydration, malnutrition, medication side effects, heart disease, and endocrine disorders. Long term low blood pressure may lead to dizziness, fatigue, and even shock. Preventive measures include increasing water intake, adjusting dietary structure, moderate exercise, regularly monitoring blood pressure, and avoiding sudden changes in body position.

1. Dehydration:

Insufficient body fluids can directly reduce blood volume, leading to a decrease in blood pressure. High temperature environment, intense exercise, or failure to replenish water in a timely manner after diarrhea and vomiting are common causes. It is recommended to drink 1.5-2 liters of water daily and supplement with electrolyte containing drinks after exercise. If there are signs of dehydration such as thirst or reduced urine output, it is necessary to immediately replenish fluids.

2. Malnutrition:

Long term lack of protein, vitamin B12, and iron can affect hematopoietic function and cause anemia induced hypotension. Daily intake of lean meat, animal liver, and dark green vegetables should be ensured, and vegetarians should supplement with soy products and nuts. Eating pig liver or chicken blood 3-4 times a week can effectively prevent malnutrition induced hypotension.

3. Drug effects:

Antihypertensive drugs, diuretics, and antidepressants may excessively lower blood pressure. During the use of these medications, blood pressure should be measured in the morning and evening every day. If the systolic blood pressure remains below 90mmHg, a doctor should be consulted to adjust the dosage. When elderly people use combination therapy, they should pay more attention to drug interactions to avoid multiple medications causing a sudden drop in blood pressure.

4. Heart disease:

Abnormal pumping function of the heart, such as bradycardia and myocardial infarction, can cause hypotension. These patients often have symptoms of chest tightness and palpitations, which need to be diagnosed through electrocardiogram and cardiac ultrasound. At the same time as treating the primary disease, elastic socks can be worn to promote venous return, and raising the head of the bed 15-20 centimeters during sleep can improve morning hypotension.

5. Endocrine disorders:

Hypothyroidism or adrenal insufficiency can affect blood pressure regulation. These patients often exhibit characteristic symptoms such as fear of cold and dry skin, and require hormone replacement therapy to control their condition. Regularly check thyroid function and cortisol levels, and keep warm in winter to reduce symptom onset.

To prevent hypotension, it is necessary to establish a healthy lifestyle, and daily salt intake can be appropriately increased to 6-8 grams, but hypertensive patients should be cautious. Recommend aerobic exercises such as brisk walking and swimming to avoid getting up suddenly after prolonged sitting. The temperature of the shower water should not be too high, and the time should be controlled within 15 minutes. Carry dark chocolate or nuts with you as emergency food. If there are signs of shock such as blurred vision or cold sweat, you should immediately lie down and seek medical attention. Pregnant women and elderly people are advised to use a home blood pressure monitor to establish a blood pressure diary to help doctors assess changes in their condition.
