Blood in stool, also known as rectal bleeding, is a common medical condition that affects millions of people worldwide. It can be a cause of concern for many, and understanding the underlying causes is crucial for proper diagnosis and treatment. In this article, we will explore the various causes of blood in stool, its symptoms, and the necessary steps to take if you experience rectal bleeding.
Rectal bleeding can be a symptom of an underlying condition, and it is essential to seek medical attention if you notice blood in your stool. The color and consistency of the blood can provide valuable information about the possible cause of the bleeding. For instance, bright red blood may indicate that the bleeding is coming from the lower gastrointestinal tract, while dark red or black blood may suggest that the bleeding is coming from the upper gastrointestinal tract.

- Inflammatory bowel disease (IBD): Conditions such as Crohn's disease and ulcerative colitis can cause inflammation and bleeding in the digestive tract.
- Infections: Bacterial, viral, or parasitic infections can cause rectal bleeding.
- Cancer: Colorectal cancer can cause rectal bleeding, especially in people over 50 years old.
