Lower rectum bleeding refers to the presence of blood in the stool, on toilet paper, or in the toilet bowl, originating from the lower part of the rectum or anus. Understanding the causes, symptoms, diagnostic methods, treatments, and prevention strategies can help manage this condition effectively. This guide provides detailed information in simple language to enhance your understanding and help you take appropriate actions.
Anatomy of the Lower Rectum
Structure
The lower rectum is the final section of the large intestine, connecting the sigmoid colon to the anus. It plays a crucial role in storing and expelling stool during bowel movements. The rectum is approximately 12 centimeters long and is surrounded by muscles that help control defecation.
Blood Supply
The blood supply to the lower rectum comes primarily from the superior rectal artery (a branch of the inferior mesenteric artery), the middle rectal artery (from the internal iliac artery), and the inferior rectal artery (from the internal pudendal artery). These arteries ensure adequate blood flow to the rectal tissues.
Nerve Supply
The rectum receives nerve signals from the autonomic nervous system, which controls involuntary functions, and the somatic nervous system, which manages voluntary actions. This dual nerve supply allows for the coordination of bowel movements and the sensation of rectal fullness or discomfort.
Types of Lower Rectum Bleeding
Lower rectum bleeding can be classified based on its source and appearance:
- Internal Hemorrhoids: Swollen blood vessels inside the rectum that may bleed during bowel movements.
