The main symptoms of chronic gastritis include upper abdominal pain, belching, acid reflux, nausea, vomiting, etc. It can be definitively diagnosed through a gastroscopy, which may reveal edema, hyperemia, and erosion of the gastric mucosa, thereby confirming the diagnosis of chronic gastritis. Once diagnosed, targeted and standardized treatment should be administered. Moreover, dietary habits must be carefully managed. Smoking and drinking alcohol should be avoided, as well as consuming spicy, fried, barbecued, and greasy foods. Fruit intake should also be controlled; for instance, only half a peach per day is advisable to avoid overconsumption. Overeating can exacerbate the burden on the gastrointestinal tract, making chronic gastritis more likely to recur. Additionally, one should not consume fruit taken directly from the refrigerator as such cold foods are strictly discouraged.
