What is generally the cause of submucosal bulging in the rectum?
Submucosal protrusion of the rectum can be caused by hemorrhoids, rectitis, rectal polyps, and other conditions.
Hemorrhoids: Prolonged sitting or improper diet may lead to abnormal bowel movements, affecting intestinal motility, causing fecal accumulation, compressing the rectum, and affecting local blood circulation, which may result in hemorrhoids, causing submucosal protrusion of the rectum or hematochezia.
Rectitis: Mainly caused by infectious factors or autoimmune factors, due to local inflammation, it often causes mucosal inflammation. In severe cases, it can involve the submucosa, muscular layer, and surrounding tissues of the rectum, causing local tissue protrusion, abdominal pain or bloating, urgency of defecation, fecal incontinence, and other symptoms.
Rectal polyps: Mainly refer to protruded lesions on the surface of the rectal mucosa. When the condition is severe, ulceration on the surface of the polyps may involve the submucosal tissue, often causing bloody stool and mucous stool.
In addition to the above conditions, it may also be caused by malignant tumors of the rectum. If abnormal bowel movements persist, it is recommended to seek medical attention as soon as possible.
