Acute gastroenteritis attacks are very painful for patients, mainly pain and diarrhea. Self-treatment is not recommended, and prompt medical attention must be sought, and symptoms can be relieved by rehydration, anti-infection, correction of acidosis, and correction of electrolyte disorders during emergency or digestive outpatient visits. The recovery period can follow the daily personal experience of health care, such as eating fewer meals and a lighter diet with low protein, easily digestible, fine and soft foods that do not increase the gastrointestinal burden. There is a term in clinical Chinese medicine called food regain, after acute gastroenteritis has improved, suddenly too much intake of food, or too much intake of food that is not easy to digest, the condition will recur, called food regain, so the diet must be taken under the guidance of a professional doctor. After acute gastroenteritis gets better, you should pay attention to rest, rest is a necessary treatment. Chronic gastroenteritis can be treated for the cause and mechanism of the disease. In chronic gastritis or acute gastritis, patients with a history of previous episodes are recommended to perform relevant examinations, such as gastroscopy, to determine whether there are problems with the stomach and intestines.
