Enteroscopy is proctitis, but I do not know what causes

There are many causes of proctitis. At present, mechanical injury or intestinal inflammation stimulation is more common. It is more common in patients with long-term constipation, dysentery and ulcerative colitis. Patients need to do further examination to clarify the specific cause, take anti-inflammatory drugs according to doctor's advice, pay attention to light diet during the period, and try to keep defecation unobstructed.
