If this happens, it is recommended to check the stool routine. If the stool routine is normal, it is mostly caused by poor digestion, so you should pay attention to your diet, eat light and easy to digest, forbid spicy, stimulating and greasy food, forbid smoking and alcohol, and develop good habits, which can relieve the symptoms. You can properly eat intestinal probiotics, such as Clostridium typhimurium, Dictyostelium subtilis or compound Lactobacillus acidophilus, etc., which also have an improvement on the intestinal function. If the stool routine is abnormal and infected, further colonoscopy is recommended to clarify whether there is a combination of chronic colitis or inflammatory bowel disease. If there is a combination of inflammatory bowel disease, it is recommended to take salicylic acid inhibitors or mesalazine preparations to relieve the symptoms.
