Some patients have symptoms such as abdominal distension, nausea and vomiting after operation. The initial diet structure is mainly light and digestible food, supplemented by appropriate activities, and the digestive system will gradually recover. Family members can use hot towels or hot water bottles to hot compress the small abdomen to promote spontaneous urination; Use kaisailu to help defecate.

Limiting fat in postoperative food, especially saturated fatty acids from animal foods, is the first principle. We should also pay attention to replenish enough protein. Foods that contain high protein and conform to the principle of low fat include skim dairy products, bean products, some birds and fish. Semi-liquid food (porridge, soup, lotus root starch, etc. ) is suitable as the main energy source. Prevent nutritional deficiency caused by drugs. Some diuretics have a great influence on the electrolyte balance of potassium, sodium, magnesium and calcium. Anticoagulant drugs can damage gastrointestinal mucosa, reduce absorption and increase the loss of iron, calcium and vitamins. Therefore, vitamin C, vitamin K, vitamin E, folic acid and iron should be supplemented after coronary artery surgery. If you are using insulin for primary diabetes, you may need to supplement B vitamins and potassium which can promote energy metabolism. Water-soluble dietary fiber is also suitable for patients after coronary artery surgery, which can prevent gastrointestinal dysfunction caused by surgical stress and constipation. Reasonable application of health food can regulate blood lipid, lower blood pressure, control blood sugar and ensure the long-term effect of surgery [5].
