Intussusception causes diarrhea. In such cases, the intussusception itself indicates an intestinal blockage. Patients with the obstruction will experience significant pain, vomiting, bloating, and closure. The anus will stop discharging gas or stool. If diarrhea occurs at this time, it is not caused by the intussusception. If the intussusception cannot be resolved, the diarrhea will improve in the short term. Of course, we must address the main issue of intussusception, and the diarrhea can be temporarily disregarded. We only need to perform air enema reduction and mainly resolve the intestinal obstruction and intussusception through surgical treatment. Diarrhea, because it is treated with IV fluids and some intestinal anti-inflammatory medications, will naturally subside.
