It may be hypoxia or low blood sugar, it may be high blood pressure, or high blood lipids, or it may be caused by heart disease, in daily life, we must pay attention to frequent visits to the hospital for physical examination, often monitor blood sugar, blood lipids, blood pressure diet, eat more nutritious food, exercise more.

Inadequate blood supply to the brain. Cerebral insufficiency is a decrease in blood flow to the brain. Some patients will suddenly feel dizzy, spinning, afraid to open their eyes, nausea and vomiting, and know in their hearts that they can move their limbs, but they dare not move.

Some patients were sweaty and pale, describing themselves as having a "feeling of dying." These symptoms can last for seconds, minutes, or hours before resolving on their own. Some have seizures several times a day or once every few days.

After the doctor's examination, if the blood pressure is not high, there is no heart disease, and there are no other abnormalities of the nervous system, the diagnosis is insufficient blood supply to the brain. If you don't want to go to the hospital, first of all, you should strengthen physical exercise, exercise is an effective way to enhance blood circulation throughout the body and improve cerebral insufficiency, such as walking, jogging, tai chi, etc. Secondly, a lot of hyperlipidemia is:"Eat"out, and therefore targetedly"Eat", high blood lipids are also expected to come down.

When hyperlipidemia is in the primary stage, that is to say, cardiovascular and cerebrovascular diseases such as hypertension and heart disease have not been found, especially young people and menopausal women, it is completely possible to adjust blood lipids by changing lifestyle and dietary conditioning, such as controlling the intake of high-fat and high-calorie foods, eating more whole grains, vegetables and fruits, quitting smoking and limiting alcohol, and insisting on exercise. (1) Reduce fat intake. Eat less animal fats, such as lard, pork, butter, sheep, cow, duck, goose, etc.

This kind of food has too much saturated fatty acids, fat is easy to be deposited on the blood vessel wall, increasing the viscosity of the blood, saturated fatty acids can promote cholesterol absorption and liver cholesterol synthesis, so that the serum cholesterol level increases. If too much is consumed, triglycerides can rise, accelerate blood clotting, and promote thrombosis. (2) Limit cholesterol intake.

Avoid foods high in cholesterol, such as organ meats, egg yolks, fish roe, squid, etc.

Many people have this experience: after squatting for a long time and then standing up suddenly, they will feel dizzy and dark. The main reason for this phenomenon is temporary anemia in the brain.

When a person is squatting, the waist and legs are twisted and turned, and the blood cannot flow up and down. If you stand up suddenly at this time, the blood will flow down quickly, resulting in local ischemia in the upper body, but the brain and eyes have particularly strict requirements for oxygen and nutrients, and they must not be slackened. If you are already weak, the situation is more serious.

However, don't panic when this happens, and you don't have to go to the hospital. If the blood supply to the head is insufficient, the heart will immediately work hard to pump blood up, and it will not take long for the body to return to normal. Of course, when standing up, don't move too hard, try as slowly as possible, so that the blood does not flow too violently, and the blood supply to the heart can keep up, and this phenomenon will not occur.
