The tip of the nose is very hard, which may be arteriosclerosis. This is a disease with damaged arteries. The main causes of arteriosclerosis are fat, high blood pressure and smoking.

Pay attention to prevention from life.

In the prevention and treatment of arteriosclerosis, we should pay attention to the following aspects:

(1) Blood pressure and urine test: Diabetes and hypertension can promote arteriosclerosis, so it is necessary to measure blood pressure and urine test regularly and pay attention to prevention. When you have diabetes and high blood pressure, you must have a thorough treatment. As long as blood pressure is lowered by antihypertensive drugs, cerebrovascular injury and myocardial infarction can be controlled.

(2) Diet: Atherosclerosis is closely related to fat. Cholesterol and neutral fat in blood should be detected regularly. Pay attention to control the amount of fat, such as egg yolk, liver, shrimp, crab and other high cholesterol content, should eat less; Chicken and fish are suitable for meat; Replacing animal oil with vegetable oil can play a certain role in controlling cholesterol. Fat should be controlled below 30% of total calories. In addition, obesity has adverse effects on arteriosclerosis and diabetes. Also control the intake of carbohydrates (rice, flour, etc. ) and sugar, and pay attention to salt intake. Although a small amount of drinking is harmless, you should not overeat. Smoking can induce angina pectoris and myocardial infarction, so you should quit smoking.

(3) Daily life: Overwork and excessive mental stress can damage blood vessels and promote the development of arteriosclerosis, which is also the direct cause of angina pectoris, myocardial infarction and cerebrovascular accident.

(4) Exercise: Appropriate exercise can reduce serum cholesterol, but once it is excessive, it will cause adverse reactions, so appropriate exercise should be carried out according to age and physical condition.
