Why blood comes with excreta?

Blood in stool (rectal bleeding) is often a sign of a problem in the digestive tract, such as hemorrhoids, anal fissures, diverticular disease, or inflammatory bowel disease. In some cases, blood in stool can be a sign of a more serious condition, such as colon cancer or rectal cancer.

Hemorrhoids are swollen veins in the anus or rectum. They can cause painless bleeding, especially after a bowel movement.

Anal fissures are small tears in the skin around the anus. They can also cause painless bleeding, especially after a bowel movement.

Diverticular disease is a condition in which small pouches form in the colon. These pouches can become infected or inflamed, leading to bleeding.

Inflammatory bowel disease (IBD) is a group of conditions that cause inflammation of the digestive tract. Crohn's disease and ulcerative colitis are two types of IBD that can cause bleeding.

Colon cancer and rectal cancer are two types of cancer that can cause bleeding. Colon cancer usually occurs in adults over the age of 50, while rectal cancer can occur at any age.

If you notice blood in your stool, it is important to see a doctor to determine the cause. The doctor may recommend tests such as a colonoscopy or sigmoidoscopy to evaluate the digestive tract and identify the source of the bleeding.
