Farting and diarrhea can be caused by improper diet, bacterial imbalance, gastrointestinal inflammation and other reasons. 1. Improper diet: when the patient’s diet is not proper, the symptoms of farting and diarrhea can occur. If the patient consumes too much cold drinks, unfresh food, spicy and stimulating food, it will cause the patient’s intestinal gas production to increase, the secretion of digestive juices to increase, and the symptoms of farting and diarrhea will occur. 2. Bacterial imbalance: When the intestinal flora of the patient is imbalanced, the food in the intestines can not be decomposed normally, resulting in abnormal fermentation of food residues, producing a large amount of gas, stimulating the gastrointestinal mucosa, causing the patient to experience the symptoms of farts and diarrhea. 3. Gastrointestinal inflammation: when the patient’s diet is unclean and causes acute or chronic gastrointestinal inflammation, foreign pathogens invade the intestinal mucosa, resulting in damage to the mucosa, resulting in diarrhea and gas production abnormalities, causing the patient to experience the symptoms of farting and diarrhea. When the patient appeared farts and diarrhea symptoms, it is best to go to the hospital for examination and treatment to avoid adverse consequences.
