A colonoscopy is recommended once every 3 to 6 months for celiac proctitis, depending on the specific case. Celiac proctitis is an inflammatory disease that occurs in the rectal area and refers to the presence of erosions at the mucous membranes of the intestines, which is caused by an abnormal immune response of genetically susceptible individuals to their own normal intestinal flora, and the increased permeability and decreased barrier function of the intestinal mucosa is an important pathogenetic factor. If the patient’s condition is severe, with frequent symptoms such as abdominal pain, mucus stools, and bleeding, he or she can have a repeat colonoscopy in about 3 months to observe the recovery of the disease, and treat the disease according to the results of the examination. If the disease is under control and the symptoms are not particularly obvious, you can also extend the time of review, and it is recommended to do the review once in 6 months. The review time is different for different degrees of celiac proctitis and should be conducted in strict compliance with the doctor’s instructions.
