The average adult's blood pressure is lower than 12/8 kPa (90/60mmHg) for a long time. People with low blood pressure are prone to syncope and shock. Hypotension is common in chronic wasting diseases, malnutrition, cardiovascular diseases, digestive tract inflammation, ulcers and so on. , and more common in young women.
The clinical symptoms caused by hypotension mainly include headache, dizziness, chest tightness and asthma, fatigue, inattention, insomnia, loss of appetite, chills in limbs, and slow pulse. Once the body position changes, it often turns black and dizzy.
For patients with long-term hypotension, the doctor's health care prescription is:
1, find a doctor in time to determine the cause of hypotension;
2, increase diet nutrition, eat more food that warms spleen and kidney;
3. Eating more salt properly can raise blood pressure and improve symptoms such as dizziness, lethargy and fatigue. But the salt intake should not be too high;
4, often eat ginger, can promote digestion, strengthen the stomach, lower blood pressure. Jiang Mo can be sprinkled in vegetable soup, or you can use Jiang Mo to soak in water instead of tea;
5. Eat less foods such as melon, watermelon, celery, hawthorn, bitter gourd, mung bean, garlic, kelp, onion, sunflower seeds and so on.

Generally speaking, when the systolic blood pressure is lower than 90mmHg and the diastolic blood pressure is lower than 60mmHg, it is called hypotension. According to statistics, the incidence of hypotension is about 4%, which can be as high as 10% in the elderly population. The hypotension we usually discuss refers to chronic hypotension. When blood pressure suddenly drops from normal or high level to obviously lower than the normal range, it is called acute hypotension, which can be manifested as syncope and shock. Chronic hypotension refers to a state in which blood pressure continues to drop. According to its clinical incidence, it can be generally divided into: constitutional hypotension, postural hypotension, secondary hypotension and so on.
Clinical manifestations: patients with mild symptoms may have no symptoms, or mild symptoms may include dizziness, headache, loss of appetite, fatigue, pale face, memory loss, indigestion, motion sickness and so on. Severe symptoms include: dizziness in upright position, chills in limbs, palpitation, breath holding, and even fainting, which requires long-term bed rest.
First, be alert: patients with hypotension suddenly fall to the ground and die!
Postural hypotension can be divided into sudden and secondary. Sudden onset is mostly due to autonomic nervous dysfunction, which causes erectile arteriole contraction dysfunction. The main manifestations are low blood pressure when standing upright, accompanied by unstable standing, blurred vision, dizziness, weakness, incontinence and so on. In severe cases, syncope may occur. Sometimes it can cause severe postural hypotension (that is, orthostatic collapse), which makes patients suddenly lose consciousness and cause irreversible shock and sudden death.
Second, be careful: patients with low blood pressure are prone to fracture when they faint!
Postural hypotension is one of the common problems of the elderly, which often occurs in the process of lying flat to sitting up or standing up. Because of posture change, brain blood flow is insufficient, and dizziness occurs for a short time. If you don't pay attention, it's easy to fall in a dizzy moment, leading to fracture or even paralysis. Postural hypotension is not seriously fatal or directly dangerous, but the biggest potential danger is that if the elderly get up too fast to go to the toilet at night, they will feel dizzy and fall down, which may cause serious problems such as fractures and head injuries. The danger is unpredictable.
Third, be careful: low blood pressure pregnant women faint and cause miscarriage!
With the popularization of hypertension knowledge, more and more middle-aged and elderly people pay attention to the treatment of hypertension. But for low blood pressure, it is generally negligent. Female patients know that with the increase of age, blood pressure will rise slowly, which is prone to hypertension. Hypotension directly leads to the development disorder of pregnant women, abnormal embryo development, destroying the growth law of prenatal babies, a small amount of vaginal bleeding, the embryo itself has problems, and the fluctuation of hormone levels in the body leads to abortion.
Fourth, tip: low blood pressure is no less harmful than high blood pressure!
Is this low blood pressure also pathogenic? In fact, we should not only pay attention to hypertension, but also prevent hypotension. Hypotension may also lead to insufficient blood supply to the heart and brain, which is no less harmful than hypertension.
Pathological hypotension (hypotension) is often accompanied by general weakness, dizziness, fatigue, sweating, palpitation and other symptoms. In addition to the decrease of arterial blood pressure, the above symptoms are more obvious when standing for a long time or changing from lying position (or sitting position or squatting position) to standing position, and even syncope occurs. Hypotension is divided into acute hypotension and chronic hypotension. Acute hypotension is more common in all kinds of shock and acute cardiovascular diseases. Chronic hypotension may have a genetic tendency, or it may be secondary to some nervous system diseases, cardiovascular diseases, chronic malnutrition, endocrine dysfunction, the recovery period of infectious diseases, the use of some antihypertensive drugs, etc., often accompanied by corresponding discomfort and abnormal examination. For young women, it is not morbid to have lower than normal arterial blood pressure without any conscious symptoms.
