Most people have constitutional hypotension, which is common in thin people and may have a family history of hypotension. Blood pressure may suddenly drop due to neurodegenerative diseases such as Parkinson's disease and autonomic nervous dysfunction, endocrine diseases such as hypothyroidism and adrenocortical hypofunction, cardiovascular diseases such as aortic stenosis, contractile pericarditis and heart failure, and chronic malnutrition diseases such as functional dyspepsia and severe diabetes. In addition, the use of some drugs can also cause hypotension. Drugs that usually act on the nervous system, such as excessive antihypertensive drugs or depression treatment and mental disorders, will affect the neuromodulation function and cause hypotension.
The elderly should prevent postural hypotension, avoid crouching at ordinary times, and move slowly and don't worry when standing. Don't let the water overheat when taking a bath. Eat more vegetables at ordinary times, avoid forced defecation, don't hold your breath, don't lift heavy objects, and don't increase the pressure on your chest and abdomen. People with low blood pressure and frequent ischemic symptoms can appropriately increase their intake of salt and water, increase their plasma volume and maintain their blood pressure level. However, excessive salt intake will increase the risk of cardiovascular disease, so it is necessary to accept the doctor's evaluation, weigh the pros and cons, and then apply it. Keeping regular exercise can enhance physical fitness, promote cardiopulmonary function and improve blood supply.
Those who cannot effectively improve their symptoms through the above methods should receive timely treatment and use drugs to raise blood pressure under the guidance of doctors. Conclusion If ischemic symptoms don't appear frequently, it is not dangerous to have constitutional hypotension. But be careful of the sudden drop in blood pressure. Because it is probably a symptom of a disease, we should find the cause and treat it actively.
