Patients with gastroenteritis need to pay special attention to their diet, especially avoiding spicy, greasy, and irritating foods. They should also avoid strong tea and coffee, as these are necessary to abstain from. It is advisable to consume more bland or easily digestible foods, such as noodles, egg custard, and rice soup. Under strict dietary control, if symptoms do not improve, medication may be necessary. Common medications include those that suppress gastric acid secretion and protect the gastric mucosa, as well as antibiotics. (Please use medication under the guidance of a doctor.)
