Symptoms of excessive stomach acid and indigestion usually indicate insufficient gastric motility and hypersecretion of stomach acid. Many gastrointestinal diseases may present these symptoms, so it is advisable to first check with a gastroscopy and a test for Helicobacter pylori. Treatment should be targeted based on the results of the tests. At the same time, it is important to develop good living habits, ensure proper balance between work and rest, and have meals at regular times and in controlled amounts, or eat smaller, more frequent meals. Try to avoid extreme hunger or overeating, and excessive eating and drinking, while also quitting smoking and alcohol. The principle for diet is to consume light and easily digestible food, and to avoid raw, greasy, spicy, and irritating foods.
