Rectal bleeding is a symptom of many different conditions, including hemorrhoids, anal fissures, inflammatory bowel disease (IBD), colorectal cancer, and others. The color of the blood can indicate where in the gastrointestinal system the bleeding is coming from. For example, fresh, bright red blood can show the bleeding is coming from lower in the bowel, nearer to the back passage, which may be a sign of hemorrhoids or fissures. Some of the common causes of rectal bleeding include:

• Hemorrhoids: Swollen blood vessels in and around the rectum that can bleed when you have a bowel movement.

• Anal fissure: A small tear in the lining of the anal canal that can cause sudden onset of rectal bleeding.

• Inflammatory bowel disease (IBD): A group of conditions that cause inflammation in the digestive tract, including ulcerative colitis and Crohns disease.

• Colorectal cancer: Cancer that starts in the colon or rectum.

• Hard stools: Constipation and straining to poop can cause rectal bleeding. When you strain, you can cause conditions like hemorrhoids or anal fissures, which may bleed. Very hard stools may tear the skin inside your anus, causing bleeding.

It is important to see a healthcare provider to determine the cause of rectal bleeding. Some causes, like hemorrhoids, may not need treatment. But others, like colorectal cancer, need urgent care. If rectal bleeding is accompanied by other symptoms such as abdominal pain, diarrhea, or weight loss, it is important to seek medical attention immediately.
