Enteritis is generally caused by viral or bacterial infections, which can lead to an imbalance in intestinal flora, causing symptoms such as nausea, vomiting, and diarrhea. Therefore, special attention should be paid to diet. It is important to avoid raw and cold foods, as well as irritating foods. Do not consume spoiled or deteriorated foods, and avoid drinking contaminated water. Fruits should not be eaten raw; they must be thoroughly washed. It is also best to develop the good habit of washing hands before meals and after using the toilet, and to enhance the cleanliness of the surrounding environment and personal hygiene.
