What causes rectal bleeding in adults

What Causes Rectal Bleeding In Adults?

There are many potential causes of rectal bleeding. Some of the most common include:

Anal Fissures:

An anal fissure is a small tear in the lining of the anus or anal canal. This tear can cause bleeding, pain, and itching. Anal fissures are often caused by constipation or passing large, hard stools.


Hemorrhoids are swollen blood vessels that develop in or around the anus and rectum. They can be internal hemorrhoids, which are found inside the rectum, or external hemorrhoids, which are found under the skin around the anus. Both types of hemorrhoids can bleed. External hemorrhoids can also cause pain, itching, and irritation.


Infections of the anus or rectum can cause rectal bleeding. These infections include anal fistulas, anal warts, perianal abscesses, sexually transmitted infections (STIs), and viral hepatitis.

Inflammatory Bowel Disease (IBD):

IBD is a condition that causes inflammation of the digestive tract. The two most common types of IBD are Crohn’s disease and ulcerative colitis. Both conditions can cause rectal bleeding.


Rectal cancer is a type of cancer that starts in the lining of the rectum (the last section of the large intestine). Rectal cancer is relatively rare in adults under age 50 but becomes more common with age. Other types of cancer that can cause rectal bleeding include colon cancer and anal cancer.

Treatment for Rectal Bleeding

Treatment for rectal bleeding depends on its underlying cause. Anal fissures often heal on their own with home care measures such as soaking in a warm bath several times per day and using over-the-counter pain relievers like ibuprofen or acetaminophen to relieve pain.

Hemorrhoids typically improve with home treatment measures such as increased fiber intake, stool softeners, over-the-counter pain relievers ,and topical creams or ointments.

Infections may be treated with antibiotics if they are caused by bacteria; otherwise they will usually go away on their own.

IBD may require medication to control inflammation as well as dietary changes; some people may also need surgery.

Rectal cancer will require surgery to remove the cancerous tissue; radiation therapy or chemotherapy may also be necessary depending on how advanced the cancer is.
