Recently, frequent diarrhea is related to gastrointestinal dysfunction, weakness of the spleen and stomach, improper eating habits, etc. Being in a bad mood for a long time will lead to plant nerve dysfunction, and the plant nervous system has a controlling role on the gastrointestinal system, so it will induce gastrointestinal dysfunction, and the peristalsis of the intestines of such patients will be hyperactive, and the absorption of nutrients in the intestines will be affected, and the performance of diarrhea will occur. This can lead to diarrhea. People with a weak spleen and stomach whose gastrointestinal function is not particularly well developed may experience diarrhea as a result of overeating or when the abdomen is attacked by cold, which may lead to increased gastrointestinal burden, ischemia and lack of oxygen to the gastrointestinal mucosa. Eating foods that are difficult to digest, or eating irritating foods such as chili peppers or cold drinks, will cause the gastrointestinal mucosa to be in a state of stress and the peristaltic speed will be hyperactive, which will also induce diarrhea.
