In terms of diet, within 8 to 12 hours after the onset of the disease, patients can eat liquid food, including rice porridge, eggs, batter and fine dried noodles. If the diarrhea is serious or sweats a lot, the patient should also drink more sugar water to supplement the lack of water, vitamins and electrolytes in the body. During the improvement period of gastroenteritis, patients can eat some liquid and semi liquid foods that are easy to digest and rich in nutrition, such as thin wonton skin and steamed chicken cake.

During the recovery period of gastroenteritis, special attention should be paid to diet control. In terms of diet, we should eat light and warm food, and avoid eating fat meat, fried food, raw cold and hard food too early, as well as fiber rich food such as celery, soybean sprouts, leeks, garlic sprouts, etc.
