Causes of Dry Stools and Rectal Bleeding

The main causes of dry stool and rectal bleeding include the following aspects: 1. Hemorrhoids: Long-term constipation or difficulty in defecation may lead to the formation of hemorrhoids. Hemorrhoids can rupture and bleed during bowel movements, manifesting as dry stool mixed with bright red blood. 2. Anal Fissure: Excessively dry stool may injure the skin around the anus during defecation, resulting in an anal fissure, which can cause bleeding and pain. 3. Gastrointestinal Bleeding: Although dry stool itself does not directly cause gastrointestinal bleeding, certain gastrointestinal diseases (such as ulcers, polyps, tumors, etc.) may simultaneously cause both dry stool and rectal bleeding. These conditions require professional medical examinations for diagnosis. 4. Unhealthy Lifestyle Habits: Insufficient water intake, lack of dietary fiber, and prolonged sitting may all contribute to dry stool and subsequently increase the risk of rectal bleeding. If such symptoms occur, prompt medical consultation is necessary to determine the underlying cause and receive appropriate treatment. Additionally, maintaining healthy lifestyle and dietary habits is an important measure for the prevention of such symptoms.
