Hypotension refers to the situation that the blood pressure of adults is lower than 90/60 mmHg for a long time, and the common ones are constitutional hypotension and postural hypotension. The former is mainly found in women with weak constitution and mental workers. The general symptoms are not obvious. In severe cases, symptoms such as precordial fatigue, dizziness, forgetfulness and depression may occur. Postural hypotension, also known as orthostatic hypotension, often occurs when you lie down, squat down and suddenly stand up or stand for a long time. At this time, transient ischemic symptoms such as dizziness will appear. To prevent and treat debilitating hypotension, we should avoid partial eclipse, mix meat and vegetables, and take food containing protein, iron, folic acid and vitamin B 12. Strengthening exercise can regulate blood pressure. Patients with postural hypotension should move slowly when standing up from lying position and squatting position. In addition, postural hypotension can also be caused by many diseases or drugs, such as spinal cord diseases, endocrine dysfunction, chronic malnutrition or improper and excessive use of antihypertensive drugs. So go to the hospital to find out the cause and then carry out targeted treatment. No matter what kind of patients with low blood pressure, they can eat more salty food, because salt will raise blood pressure. Drinking more water and exercising more every day can increase blood volume, and you can also eat longan, jujube, red beans and so on. It can not only increase nutrition, but also help correct hypotension. It is generally considered that the blood pressure of upper limbs is lower than12/8kpa (90/60mmhg) as hypotension. Because of low blood pressure, slow and weak blood circulation and ischemia of distal capillaries, the transport of oxygen and nutrients to tissues and cells is affected, and carbon dioxide and metabolic wastes are taken away. After a long time, the function of the body is greatly reduced. According to its etiology, it can be generally divided into three categories: (1) Postural hypotension: that is, standing upright suddenly or standing for a long time from a lying position, and the systolic blood pressure drops by more than 2.67kPa, which often appears after getting up in the morning, with black eyes and dizziness, and is more common in men aged 40-70, who are weak in bed after a long illness or take antihypertensive drugs with vein dilating function. (2) Symptomatic hypotension: caused by certain diseases or drugs, such as syringomyelia, severe mitral or aortic stenosis, chronic malnutrition, taking antihypertensive drugs, etc. (3) Constitutional hypotension: It is generally considered to be related to emaciation, which is more common in women aged 20-40. Most of them have a family genetic history, some are asymptomatic, others have symptoms such as fatigue, forgetfulness, dizziness, headache, palpitation, even syncope, or precordial compression. Many patients are accompanied by headache, dizziness, chest tightness, shortness of breath, listlessness, inattention, shallow sleep, poor appetite, swollen feet and other symptoms. These performances are more prominent when the air and humidity are high in summer. This disease is more common in people and women with weak constitution. But some people have no obvious abnormal feeling. Traditional Chinese medicine believes that hypotension is caused by Yang Qi disharmony of spleen and kidney, and the treatment pays attention to warming spleen and kidney and increasing Yang Qi. Prevention and treatment of hypotension Clinically, some patients who complain of dizziness always ask themselves whether they are anemic, but their hemoglobin is normal, and their blood pressure is lower than 90/60 mmHg (lower than 100/ 60mmHg for people over 65 years old), which should be hypotension. Hypotension and anemia cannot be equated. It is not caused by too little blood volume, but is related to blood viscosity, vascular aging and insufficient vascular elasticity. Traditional Chinese medicine does not have the name' hypotension', and most of them belong to the category of' dizziness',' fatigue' and' fainting'. Traditional Chinese medicine believes that this disease is more common in patients with spleen and stomach weakness; Mental workers; Or vulnerable elderly patients with heart disease. It is believed that it is mostly caused by deficiency of qi and yang, deficiency of yin and blood or deficiency of both qi and yin. Qi deficiency and yang deficiency, heart pulse agitation and weakness, qi disorder, poor yang clearing, and heart pulse dystrophy; Deficiency of yin and blood and blood vessels also lead to heart and brain dystrophy, or dizziness or even fainting due to kidney-yang deficiency and brain marrow emptiness; Deficiency of both qi and yin, imbalance of yin and yang, low viscera function, dizziness, tinnitus, chills, backache and leg weakness, anorexia, fatigue, hypotension and other clinical symptoms. The best answer is that the brachial artery blood pressure in adults is lower than 12/8 kPa, which means hypotension. Hypotension can be divided into acute and chronic: 1. Acute hypotension refers to a sudden and obvious drop in blood pressure from a normal level or a high level, mainly manifested as syncope and shock. 2. Chronic hypotension can be divided into two types: physical hypotension and postural hypotension. The former is common in weak constitution, more women, and has a family genetic tendency. Most of them have no conscious symptoms. Their hypotension was only found by accident in physical examination, which has no important clinical significance. Some patients have dizziness, headache, even syncope, palpitation and other neurosis-like symptoms, usually caused by some chronic diseases or malnutrition; The latter is a sudden change from supine position to upright position, or hypotension occurs when standing for a long time, which can cause syncope in severe cases. The typical symptom is that blood pressure drops when standing upright, but there is no sweating. The pathogenesis may be the dysfunction of autonomic nervous system, which leads to the dysfunction of arteriole contraction when standing upright. It can be seen that anemia and hypotension are two different diseases, and there is no causal relationship in clinic. Diet conditioning is one of the effective measures to treat hypotension. Dietotherapy can gradually improve the physical quality of patients, improve cardiovascular function, increase myocardial contractility, increase cardiac output, improve arterial wall tension, make blood pressure gradually rise and stabilize at a normal level, and eliminate various discomfort symptoms caused by hypotension. The dietary choices of patients with hypotension include the following points: 1, eating dizziness and vegetarian food, reasonably matching diet, ensuring the intake of comprehensive and sufficient nutrients, and gradually making the physique from delicate to strong. 2. If anemia is accompanied by low red blood cells and insufficient hemoglobin, you should eat more foods rich in "hematopoietic raw materials" such as protein, iron, copper, folic acid, vitamin B 12 and vitamin C, such as pig liver, egg yolk, lean meat, barreled milk, fish and shrimp, shellfish, soybeans, tofu, brown sugar and fresh vegetables and fruits. 3, lotus seeds, longan, jujube, mulberry and other fruits, with the effect of nourishing the heart and enriching the blood, strengthening the spleen and nourishing the brain, can be eaten often. 4. Eat more foods and condiments that can stimulate appetite, such as ginger, onion, vinegar, soy sauce, sugar, pepper, beer, wine, etc. Contrary to hypertension, this disease should choose an appropriate diet with high sodium and cholesterol. Sodium chloride (that is, salt) needs to be ingested12 ~15g every day. Eat brain, liver, eggs, cream, fish eggs, pig bones and other foods. Rich in cholesterol, it is beneficial to increase blood cholesterol concentration, increase arterial tension and raise blood pressure. 6, often eat ginger, can promote digestion, stomach, lower blood pressure. Jiang Mo can be sprinkled in vegetable soup, or Jiang Mo can be soaked in water instead of tea. 7, eat less melon, watermelon, celery, hawthorn, bitter gourd, mung bean, garlic, kelp, onion, sunflower seeds and other foods with antihypertensive effect. Dietotherapy method 1, black-bone chicken 1 (about 1500g). Wash the chicken, remove the hair, perform laparotomy, put 60g of angelica head, 50g of astragalus root, 50g of brown sugar 150g and 50g of rice wine into the chicken belly, then sew the chicken belly tightly, steam it in a pot, and eat meat and soup once every half month for two months. 2. 15 red dates, 150g millet, washed? 1 chicken, cut into pieces, stir-fry over high fire, add seasoning, cook until 80% cooked, add red dates and chestnuts and stew cooked food. 3. 1 crucian carp, 60 grams of glutinous rice. Wash the fish (without scaling) and cook it with glutinous rice into porridge. Use twice a week for two months. 4. Tender hen 1 hen, astragalus membranaceus 30g, fresh gastrodia elata 100g (dried product 15g). Wash the chicken, blanch it in boiling water and rinse it with cold water. Slice Gastrodia elata and Astragalus membranaceus into chicken belly. Put the chicken in a casserole, add appropriate amount of onion ginger, salt, wine, dried tangerine peel 15g, and appropriate amount of water, simmer until the chicken is cooked, and add 2g pepper to serve. 5, 20 grams of red dates, Adenophora adenophora 15 grams, raw and cooked land 10 grams, add appropriate amount of water, steam in a stew for 3 hours, add appropriate amount of honey, eat twice a day, take 15 days. According to research, garlic, onions, shallots and so on. It has the function of smoothing blood and preventing thrombosis. Thrombosis is caused by platelet aggregation. Under normal circumstances, platelet aggregation factor (TXA2) and physiologically active substance (PG 12) in human body maintain a perfect balance. But once you reach old age, you will lose this balance, and the production of PG 12 will be inhibited, which will easily lead to thrombosis. The researchers investigated the ability of onion vegetables to inhibit platelet aggregation and found that there are three new substances in garlic, which have strong effects. Many active substances were also found in onion, among which indomethacin and aspirin, one of the more representative anti-inflammatory drugs, had a strong inhibitory effect on platelet aggregation. This active substance is the kind of substance that stings people's eyes and nose when we cut garlic and onions. In addition, spinach, peppers, tomatoes, melons and other vegetables, fruits and some condiments also contain this active substance. Suggestions on the conditioning of nutritional products: ■3 times dosage: B vitamin royal jelly ■2 times dosage: vitamin C spirulina tablets ■ 1 time dosage: compound vitamin iron folic acid tablet protein powder: enhance the immunity of the body and enhance the hematopoietic function of the body. Restore the elasticity of the blood vessel wall. Vitamin c: promote the absorption and utilization of iron in the body and promote the utilization of folic acid.
