So, what are the common clinical symptoms of proctitis? Since the rectum is close to the anus, the symptoms are primarily manifested as diarrhea, abdominal pain, and bloating. Some patients experience alternating constipation and diarrhea. Generally, there is often mucus or blood in the stool, and there is usually a burning sensation in the anus during bowel movements. Additionally, due to the irritation from rectal secretions, eczema and itching around the anus can occur. Diagnosing proctitis is relatively easier compared to diagnosing pancolitis. Diagnosis is usually made through sigmoidoscopy or colonoscopy, and sometimes biopsies are needed for confirmation.
