There are ways to repair the intestinal mucosa, such as dietary adjustments, medication and so on. 1. Dietary adjustments: Eat light, easy-to-digest food in daily life, keep regular diet, avoid overeating, avoid spicy and irritating food, cold food, avoid coffee, strong tea, alcohol, etc., to reduce the burden on the gastrointestinal tract. 2. Drug therapy: mainly use drugs that can play a protective role for the intestinal mucosa, such as teprenone capsules and so on. When the intestinal mucosal damage is more serious, diarrhea and other symptoms can be used to stop diarrhea with montelukast, which can generate a protective layer of mucosa in the intestinal tract and promote the recovery of intestinal function; probiotics can also be used, such as bifidobacteria, Bacillus licheniformis, etc.. Patients who need intestinal mucosal repair are advised to go to the hospital if they cannot be relieved by dietary adjustments.
