Diagnosis Path: Medical history review to understand symptoms and possible causes Physical examination, including a rectal exam Endoscopic procedures such as sigmoidoscopy or colonoscopy to visually inspect the rectum and obtain tissue biopsies Laboratory tests including stool analysis to detect infection or inflammation markers Imaging studies if necessary to assess the extent of inflammation or rule out other issues

Treatment Protocols: Anti-inflammatory medications like aminosalicylates (e.g., mesalamine) Topical therapies such as suppositories or enemas containing corticosteroids or other anti-inflammatory agents Immunosuppressive drugs in more severe cases to control immune response Managing dietary and lifestyle factors, including avoiding irritants and maintaining a balanced diet Addressing constipation or diarrhea with appropriate remedies Regular monitoring and follow-up to assess disease activity and adjust treatments as needed
