Tummy ache after meal and pooping can usually be caused by intestinal smooth muscle spasm, irritable bowel syndrome and gastrointestinal dysfunction. Patients need to go to the hospital in time to identify the specific causes, and then to carry out symptomatic treatment. Common causes and treatment 1, intestinal smooth muscle spasm: When the intestine is subject to inflammation, cold, diet and other external stimuli, it can lead to smooth muscle spasm, causing violent peristalsis of the intestine, which leads to abdominal pain, strong bowel movements and other symptoms. And when the feces in the intestine is expelled from the body, the abdominal pain can usually be effectively relieved because the pressure in the intestinal cavity is reduced. Therefore, to avoid spasm of the intestinal smooth muscle, patients need to maintain a regular routine, not to eat an unclean diet, and to maintain a relaxed mood. If the symptoms are serious, you need to seek medical treatment in time; 2, irritable bowel syndrome: when eating or emotional tension, can accelerate intestinal peristalsis, resulting in abdominal pain and accompanied by diarrhea and other symptoms. Usually the pain in the lower abdomen is the main focus, the attacks are often irregular, and can be relieved after exhaustion or defecation. It is usually treated by removing the causative factors and enabling the patient to develop good lifestyle habits, as well as relieving anxiety. If necessary, you can follow medical advice to use Alverine, Pivetonium bromide, montelukast and other drugs; 3, gastrointestinal dysfunction: mainly due to intestinal flora disorders, which in turn affects the abnormal intestinal function. Usually, probiotics can be used under the guidance of professional doctors to promote the return of normal intestinal flora, and in serious cases, domperidone, trimethoprim, loperamide and other drugs can be used for treatment. Patients need to pay attention to abdominal warmth, avoid getting cold, develop good dietary habits, try to choose light, easy-to-digest food, such as rice porridge, egg custard, etc., avoid overeating, violent mood swings, etc., so as not to aggravate the symptoms of discomfort.
