So, what are the typical clinical symptoms of proctitis? Since the rectum is close to the anus, the symptoms mainly include diarrhea, abdominal pain, and bloating. Some patients experience alternating constipation and diarrhea. Generally, stools may contain mucus or blood, and there is often a burning sensation in the anus during bowel movements. Additionally, the irritation from rectal secretions can lead to eczema and itching around the anus. Diagnosing proctitis is relatively easier compared to pan-colitis. Diagnosis is usually made through proctoscopy or sigmoidoscopy, and sometimes confirmatory diagnosis requires these biopsies.
