Hyperlipidemia is a disease that many people encounter nowadays. Many people don’t pay much attention to it at first, but this disease may cause some other diseases if they don’t pay attention to it, mainly because it can damage liver function, cause high blood pressure, lead to coronary heart disease and endanger coronary arteries. As the saying goes, everything happens for a reason, and the formation of hyperlipidemia must be due to some reasons. Primary causes are related to the environment and family genetics. Secondary is caused by diabetes, hypothyroidism, obesity, pancreatic disorders, etc. A proper diet and lifestyle are important for the prevention of hyperlipidemia. For patients with hereditary predisposition to hyperlipidemia, medication does not significantly improve the condition, and the main way to improve it is by adjusting the diet structure. Try not to eat or eat less cholesterol-containing foods, such as animal offal, brains, bone marrow, fish roe, shellfish, squid, eel, etc. It is important to eat a lot of fibrous vegetables and fruits, which contain a lot of plant sterols that can inhibit cholesterol absorption and play an anti-atherosclerotic role. Drinking alcohol in moderation or in small amounts can also lower cholesterol, 45 ml of white wine or 90 ml of dry red or 188 ml of beer daily. For patients who already have hyperlipidemia, on the one hand, they should control their diet and on the other hand, they should do moderate exercises such as jogging. Through exercise, the lipase activity in fat increases and blood lipids decrease accordingly. Some patients have normal blood lipids but have hypertension, diabetes and coronary heart disease, which also require diet control, active exercise and drug treatment under the guidance of doctors.
