The stomach feels especially heavy considering that it is related to irregular diet, gastric secretion dysfunction, gastrointestinal diseases and other reasons. 1. Irregular diet: for example, frequent overeating, long-term high-fat and high-protein diets, eating too fast and too quickly will result in food that is difficult to mix adequately with digestive juices, resulting in indigestion and flatulence of the stomach and intestines. When consuming too much gas-producing food (e.g. groundnuts) at one time, a large amount of gas will be produced during the decomposition of these foods, leading to flatulence. It can also be characterized by a particularly heavy feeling in the stomach. 2. Gastric secretion dysfunction: When the number of cells that secrete digestive enzymes and gastric acid decreases, the secretion of digestive enzymes and gastric acid also decreases, which will reflexively inhibit the contraction and peristalsis of the stomach muscles, resulting in gastric dyskinesia. The symptoms of gastric dyskinesia are manifested in the stomach feeling particularly heavy. 3. Gastrointestinal diseases: such as peptic ulcer, gastritis, intestinal obstruction and other diseases, can lead to gastrointestinal digestive function is reduced, so that its ability to digest food significantly weakened, resulting in the gathering of gas, manifested as flatulence, the feeling of heaviness in the stomach. The stomach feels particularly heavy, it is recommended to chew and swallow slowly when eating, not to overeat, eat less spicy and stimulating food, and should eat a light diet. If the symptoms are serious, it is recommended to go to the hospital for examination to clarify the cause of the disease and facilitate symptomatic treatment.
