Chronic gastritis is caused by many factors, including various medications, irritating foods, gallbladder adenomas, environmental conditions, and personal factors, among others. Therefore, while we treat the symptoms, post-treatment maintenance of the stomach is crucial. Diet plays a significant role here. It is important to avoid particularly irritating foods, including items that are too cold, too hot, too cool, too spicy, or too acidic. Raw foods and those that are difficult to digest should also be avoided. It's beneficial to eat slowly and chew thoroughly; avoid overeating or eating too hastily. Thus, it's essential to eat regularly and in proper amounts. Some fruits, like apples, can be consumed, although they should be limited in the early stages of gastritis if there is excessive stomach acid. However, intense beverages like strong tea and coffee, and spicy foods such as chili peppers, should be avoided.
