Anal cramping gastrointestinal dysfunction usually occurs when the intestines are normal but function abnormally, causing the intestines to not be able to pass stool and absorb water well. It is usually treated with dietary changes, probiotics, and medications to promote gastric motility. 1. Dietary changes: Increase the patient’s fluid and fiber intake. Eat a light diet and avoid spicy and irritating foods that stimulate the stomach and intestines. Drink more water and avoid high-fat diet. 2. Take probiotics: regulate the bacterial flora in the stomach and intestines, so that the bacterial flora to return to normal, but also reduce the visceral hypersensitivity and inflammatory response, which is very helpful in regulating gastrointestinal function. 3. Promote gastric power: insufficient gastrointestinal power leads to gastrointestinal contents not being able to be discharged, resulting in anal distension. You can take domperidone, mosapride and other drugs under the guidance of a doctor to promote intestinal peristalsis and reduce symptoms. If the symptoms are not relieved after lifestyle modification, you should consult a doctor in time to clarify the cause of the disease and carry out treatment under the guidance of the doctor.
