After heart bypass surgery, balanced and comprehensive nutrition is appropriate, such as eating some fresh fruits and vegetables, for example, apples, broccoli and so on, and also need to eat some foods rich in high quality protein, for example, eggs, milk, fish, soybean products, etc. These foods can not only give the body a lot of nutrients, but also increase blood circulation and metabolism. These foods can not only give the body a lot of nutrients, but also increase the body’s blood circulation and metabolism, which is conducive to the recovery of the disease. However, there are also dietary taboos. You should not eat foods that are high in fat, high in cholesterol, and spicy and stimulating, such as fatty meats, french fries, fried chicken, and chili peppers, etc. These foods not only cause certain stimulation to the body, but also elevate blood lipids, leading to atherosclerosis and the formation of plaque, which results in narrowing of the blood vessels, triggering a lack of blood supply that may lead to recurrence of the disease and so on. Therefore, after the operation, we should strictly follow the doctor’s instructions to take medication on time, go to the hospital for regular checkups, and develop good living habits, pay more attention to rest, and communicate with the doctor in time if any adverse symptoms occur.
