In small bowel erosion, most symptoms are often pain in the periumbilical region, mostly paroxysmal, often characterized by localized cramping. This pain lasts for an hour or two hours, and most of it is relieved, and the pain is accompanied by bowel movements. The treatment of small intestinal erosion is to give drugs that regulate intestinal function and improve intestinal flora, such as Bifidobacterium complex acidic bacteria capsules, pivirimium bromide tablets, lactulose oral solution or to give symptomatic treatment with Chinese medicines, such as Puyuan and stomach capsules and pellets for gastric pain. Small intestinal lesions are relatively rare and are diagnosed clearly only by capsule endoscopy or small intestinal microscopy. Therefore, this type of celiac disease does not require too much worry, and most of them can be clinically cured after 2-3 weeks of systematic and comprehensive treatment, after which attention to diet and rest and relaxation is required.
