Indigestion is one of the common symptoms of upper gastrointestinal diseases, which can be functional or organic, such as functional dyspepsia, gastroptosis, chronic gastritis, peptic ulcer, gastrointestinal tumors, drug-induced gastric diseases, etc. As for how to manage digestive disorders related to stomach diseases, it is primarily necessary to identify the cause. It is generally advocated to conduct upper gastrointestinal radiography, gastroscopy, and Helicobacter pylori testing, and to adopt targeted treatments based on the test results, such as eradicating Helicobacter pylori, enhancing gastric motility, protecting the gastric mucosa, and so on. At the same time, it is important to develop good dietary and living habits, balance work and rest, quit smoking and drinking, eat on a regular schedule or eat smaller, more frequent meals, and try to avoid overeating or binge eating, as well as excessive consumption of raw, greasy, or spicy and irritating foods.
