Blood in stool, also known as rectal bleeding, refers to the presence of visible or non-visible blood in the stool. This can be a sign of a number of different conditions, ranging from relatively minor issues to more serious medical problems.
There are many potential causes of blood in stool, including hemorrhoids, anal fissures, diverticulitis, inflammatory bowel disease (IBD), colon polyps, and colorectal cancer. Infections, such as bacterial or parasitic infections, can also cause rectal bleeding.
The appearance of blood in stool can vary depending on the underlying cause. For example, bright red blood in the stool typically indicates bleeding in the lower digestive tract, while dark, tarry stools may be a sign of bleeding higher up in the digestive system.
If you notice blood in your stool or experience any other concerning symptoms, such as abdominal pain, changes in bowel habits, or unexplained weight loss, it is important to speak with a healthcare provider for evaluation and appropriate treatment. Depending on the underlying cause, treatment may involve medications, lifestyle changes, or surgery.
