The healing time of proctitis can not be generalized, it needs to be considered according to the cause of the patient’s disease, condition, medication and other circumstances, and it usually takes 2~3 weeks. Proctitis can be categorized into ulcerative proctitis, infectious proctitis (including sexually transmitted diseases and intestinal infectious diseases), radiation proctitis, and allergic proctitis according to the cause. According to different causes, the time of medication is different, and the prognosis time is also different. 1. Ulcerative proctitis: it is a chronic non-specific inflammatory disease of the rectum and colon whose etiology is not yet clear. In mild cases, the symptoms can be relieved with medication and usually recover in about 2 weeks; in severe cases, the prognosis is poorer and easy to recur, and surgery can be performed according to the doctor’s recommendation to improve the prognosis. 2. Infectious proctitis: anti-infective treatment should be carried out against the pathogenic bacteria. If the symptoms are mild, eliminating the triggering factors, timely use of medication can be cured in 2~3 weeks; if it turns into chronic inflammation, the symptoms recur, it is difficult to cure. 3. Radioactive proctitis: refers to the proctitis disease that occurs after radiation therapy.
