- Inflammatory Bowel Disease (IBD): Conditions like Crohn’s disease or ulcerative colitis that cause inflammation in the digestive tract.
- Peptic Ulcers: Sores in the lining of the stomach or small intestine.
- Colorectal Cancer: Tumors in the colon or rectum can cause bleeding.
- Gastrointestinal Infections: Infections causing inflammation and bleeding.
- Polyps: Non-cancerous growths in the colon or rectum that can bleed.
Risk Factors
- Age: Risk increases with age, especially for conditions like colorectal cancer.
- Family History: A family history of gastrointestinal diseases or cancer.

Complications
