People who are addicted to smoking should stop smoking immediately if they have gastroenteritis. Even if an ordinary smoker has gastroenteritis, he should smoke less or not smoke. The main reason is that the harmful substances produced by smoking can cause vasoconstriction in the stomach, affecting the blood supply to the cells of the stomach wall and reducing the resistance of the gastric mucosa to induce gastric disease. Drinking alcohol can also damage the gastric mucosa and promote the absorption of carcinogenic substances. Cigarette packets have the words “smoking is harmful to health” written on them, so it is better not to smoke whether you have gastroenteritis or other diseases. In addition to reducing smoking, patients with gastroenteritis should also pay attention to: 1. control the amount of milk intake to avoid bloating. 2. 2, prohibit deep-fried cooking and thick condiments. 3, forbidden to eat gas-producing, indigestible or stimulating food. 4, food containing crude fiber and fruits and vegetables should be eaten as little as possible. In terms of treatment, good results should be obtained on the basis of improving the quality of life, avoiding adverse stimuli, adjusting diet and strengthening physical exercise, together with some medication. Some herbal preparations can also be taken to nourish and protect the stomach.
