It is a characteristic of irritable bowel syndrome to have abdominal pain or diarrhea easily after eating spicy food. Generally, spicy food has a direct damaging effect on the intestinal mucosa, which can damage the intestinal mucosa, causing edema, congestion and even erosion, and this often leads to an increase in the osmotic pressure of the intestinal mucosa, causing an increase in diarrhea symptoms. For some cases of chronic enteritis, intestinal dysfunction, and digestive malfunction, diarrhea can also occur if the food is stimulated. For ulcerative colitis or inflammatory bowel disease, may not tolerate spicy food, can also appear diarrhea characteristics. Therefore, it is best to improve the routine stool examination and, if necessary, the colonoscopy to further assist in the diagnosis and treatment of diarrhea that can easily occur with frequent consumption of spicy foods. You can give appropriate symptomatic treatment with glutathione tablets, pivetonium bromide tablets and bifidobacterium capsules.
