The old man is older. Now his condition is caused by changes in blood quality and blood environment. The contents of sugars, lipids, cholesterol, low density lipoprotein and other substances in blood increase, leading to metabolic imbalance. At this time, the blood will be very thick, high blood sugar will form diabetes, and the viscous flow of blood will be relatively slow, leading to an increase in blood pressure. Over time, it is easy to form atherosclerosis on the tubular artery of the heart. This is coronary heart disease. There are many precautions in diet:

You can eat more rice, porridge, noodles, milk, vegetable oil, vegetables, fruits, light tea and so on. And avoid spicy food, such as smoking, baking, frying, etc. Be sure to drink more boiled water, there are many details in life. What you need to pay attention to is to get up in the morning and lie down for about 5 minutes before getting up. Your mood should be stable, not angry and excited.

I wish the old man a speedy recovery. If we pay attention to diet and control the development of the disease in practice, I suggest that it is better to use some Chinese medicines in moderation for overall conditioning.
