Because of the high morbidity, mortality, disability, recurrence and complications of stroke, the medical community has ranked it as one of the three major diseases threatening human health, along with coronary heart disease and cancer. The main causes of stroke are as follows: hypertension (25%): hypertension is the cause, stroke is the consequence, and blood pressure is directly proportional to the morbidity and mortality of stroke. High blood pressure increases the tension of blood vessels, which means that the blood vessels are “tense”, and over time, the elastic fibers of the vessel wall will break, causing damage to the vessel wall and making it easy for lipid substances in the blood to penetrate into the lining of the vessel wall. On the basis of lesions in the cerebral arteries, when the patient’s blood pressure suddenly rises, it is easy to cause a stroke. Diabetes mellitus (15%): Diabetes mellitus is one of the predisposing factors for stroke disease. Insufficient insulin causes glucose to be converted into fat and the storage of glucose is reduced, and a large amount of fat is broken down into triglycerides and free fatty acids, especially cholesterol increases more significantly, thus causing hyperlipidemia and accelerating atherosclerosis in diabetic patients, which is a noteworthy problem. In general, diabetic patients are often associated with both microangiopathy and atherosclerosis. Hyperlipidemia (20%): Blood lipids are an important substance in the body and have many very important functions, but they should not exceed a certain range. If there is too much blood lipid, it tends to cause “thickening” and deposition on the walls of blood vessels, gradually forming small plaques. These “plaques” increase in size, gradually blocking the blood vessels, slowing down the blood flow and in severe cases interrupting the blood flow. This situation occurs in the brain, there will be ischemic stroke. Obesity (10%): obese body, clinical observation found that obese people compared with the general population, the chance of stroke is 40% higher. Why are fat people prone to stroke? Experts say that this is related to the endocrine and metabolic dysfunction of obese people, the increase of cholesterol and triglycerides in the blood, and the decrease of high-density lipoprotein. In addition, fat people are often accompanied by diabetes, hypertension, coronary heart disease and other diseases, which are risk factors for stroke. Smoking (5%): tobacco contains a large amount of nicotine, nicotine can make a person’s weight loss, appetite, but at the same time there is insulin resistance and cortisol increase, these are factors that lead to increased blood sugar and blood pressure, the final formation of the above causes lead to stroke. The “blood” of the twelve days, people are often emotional, most likely to cause a sudden increase in blood pressure, lipids and other indicators, is very easy to lead to the occurrence of acute stroke, need to strictly prevent and control. And in the event of a stroke, go to a regular hospital for emergency treatment in a timely manner.
