Hypertension means that the systolic blood pressure is lower than 12 kPa and the diastolic blood pressure is lower than 6.7 kPa. Common ones are dizziness, listlessness, cold stomach, tepid limbs, decreased resistance, and easy to catch a cold. Hypotension is generally divided into three types: primary, secondary and temporary. Blood pressure is determined by myocardial contractility, blood volume, vascular tension and resistance. Therefore, diet and medicated diet for treating hypotension should focus on these three aspects. First of all, the diet should be scientifically and reasonably matched, with both meat and vegetables, combined with appropriate physical exercise, to make the thin body stronger and improve the functions of the brain and cardiovascular system. You should eat more dried and fresh fruits such as lotus seeds, longan, jujube, mulberry, red beans and peanuts. These foods can not only enhance the function of blood vessels, but also improve the function of regulating blood pressure in the brain nerve center and significantly correct hypotension. Secondly, anemia patients should eat more lean meat, egg yolk, pork liver, fish and shrimp, shellfish, milk, bean products, spinach, tomatoes, oranges, grapes and other foods with blood-enriching effects. You should also eat some foods rich in cholesterol. The increase of cholesterol in blood will promote the tension of blood vessels and raise blood pressure. Third, patients with low blood pressure can also drink low-alcohol wine, such as beer and wine. Wine can promote gastrointestinal peristalsis and increase appetite. Low-alcohol wine can also increase high-density lipoprotein in the blood, which is also good for raising blood pressure. Hypoglycemia is a syndrome caused by various reasons that blood sugar suddenly drops below 2.8 mmol/L (50 mg/dl), which leads to excessive excitement of sympathetic nerve and brain dysfunction. Blood sugar drops rapidly, and patients often have symptoms such as hunger, nausea, vomiting, fatigue, weakness, nervousness, anxiety, palpitation, cold sweat, pale face, high blood pressure, and trembling hands and feet. When blood sugar drops further, patients may appear trance, lethargy, convulsion and coma; Long-term severe hypoglycemia can cause brain damage, such as coma for more than 6 hours, which can cause irreparable brain damage and lead to death. The most common cause of hypoglycemia is excessive or improper use of insulin and sulfonylureas by diabetic patients. Elderly diabetic patients are prone to hypoglycemia before lunch or dinner even if their condition is stable and untreated. For the prevention of hypoglycemia, first of all, eat within 30 minutes after insulin injection, and supplement a small amount of diet in time when the activity increases. Don't forget to eat on time when you go out to work, and patients who take sulfonylureas should also add meals in time; Secondly, patients injected with mixed insulin should pay special attention to eating dinner on time and eating staple food or eggs and dried tofu before going to bed; Third, take some sweets and biscuits with you to prevent hypoglycemia. Acute hypoglycemia: 1, patients with mild reaction and conscious mind, take 25-50g of white sugar or brown sugar, take it with warm boiled water or drink other sugary drinks; Those who are slightly heavier eat 25 grams of steamed bread, bread or biscuits, or 1-2 fruit. The general reaction will disappear after 10 minutes. 2, hypoglycemia reaction is heavier, and the mind is not very clear. White sugar or brown sugar can be put into the patient's mouth to melt and swallow; Or make syrup and feed it slowly. If you are still awake after taking sugar 10 minutes, you should be sent to a nearby hospital for emergency treatment immediately. 3. For coma patients with hypoglycemia, 40 ml of 50% glucose should be injected intravenously immediately to take oxygen, which will take effect soon, or glucagon 1 mg, 15 minutes later. After waking up, the patient must be given sugar water to prevent the next reactive hypoglycemia. When hypoglycemia occurs, it should be handled correctly in time. The only energy source of the human brain is glucose, so hypoglycemia has the greatest impact on the body. If not treated in time, it will lead to irreversible damage to brain tissue and even death in a short time. What is particularly worrying is that when diabetic patients have hypoglycemia reaction, patients and their families often don't know what happened, but blindly let patients take hypoglycemic drugs according to their experience, which is counterproductive and makes their condition worse. So, how to find hypoglycemia in time and make correct treatment? Generally speaking, the typical symptoms of hypoglycemia are sweating, pallor, fatigue, blackening and other symptoms. Once the above situation is found, the correct treatment is: if possible, the blood sugar value should be measured in time to diagnose hypoglycemia; (1) If it is only mild hypoglycemia and the patient is conscious, he can eat a few sweets, biscuits or drink half a cup of sugar water, which can quickly correct hypoglycemia. Generally, the symptoms of hypoglycemia will disappear after ten minutes. After eating the above foods, you can eat some rice or steamed bread, dried tofu and other foods appropriately to prevent the recurrence of hypoglycemia; (2) If the above methods still have no effect or the patient is unconscious, he should be sent to the hospital for emergency treatment immediately, and bring the hypoglycemic drugs that the patient usually takes, so that the doctor can understand the condition. (3) Patients with severe hypoglycemia should not be fed food and should be taken to the hospital immediately. Blood sugar was measured immediately after being sent to the hospital, and 20 mg of 50% glucose was injected intravenously. After the symptoms are relieved and awake, glucose can be injected intravenously to prevent the recurrence of hypoglycemia. In particular, some patients with hypoglycemia caused by oral hypoglycemic drugs may still be comatose again after treatment, which requires close observation for four or five days. I wish you a speedy recovery.
