Rectal Bleeding

Rectal Bleeding Explained

Rectal bleeding is any blood that appears from the anus, whether you see it on the toilet paper, in the water, or streaked on the stool. Sometimes the blood is bright red; other times it may look darker or mixed into the stool.

Common causes include hemorrhoids, small tears in the skin (anal fissures), inflammation, diverticular disease, polyps, or, less often, colorectal cancer. Even though many causes are benign, it is always worth talking about bleeding with a digestive specialist so we can determine what’s going on and whether you need further testing.

Symptoms

Rectal bleeding can appear in different ways, from a few streaks of bright red blood on the tissue to darker blood mixed with stool. Some people notice itching, pain with bowel movements, or changes in bowel habits along with the bleeding.

Symptoms include:
Bright red blood on the toilet paper after wiping
Red blood dripping into the toilet bowl
Streaks of blood on the outside of the stool
Darker or maroon-colored stool
Mucus or irritation around the anus
Rectal pain or burning with bowel movements
A feeling of fullness or a lump at the anus (possible hemorrhoid or prolapse)
Change in bowel habits (new constipation or diarrhea)
Unintentional weight loss or fatigue along with bleeding

When to call

Call our office promptly if rectal bleeding lasts more than a day or two, keeps coming back, or starts new at age 40+. Contact us sooner if you have a family history of colon polyps/cancer, bleeding with bowel changes, abdominal pain, or weight loss, or signs of anemia like unusual fatigue or weakness.

Call 911 or go to the nearest emergency room for heavy rectal bleeding, large clots, or black tarry stools. Seek emergency care if you feel dizzy, faint, or have a racing heartbeat, if you develop severe/worsening abdominal pain, or if bleeding occurs with fever, chills, or you feel very unwell.

Evaluation & Tests
Management & Treatment

We start by asking detailed questions about how the bleeding looks, how often it happens, and what other symptoms you have, such as pain, weight loss, or changes in bowel habits. A physical exam may include looking at the anal area and a gentle rectal exam.

Depending on your age, risk factors, and symptoms, we may recommend tests such as a colonoscopy to look at the entire colon and rectum, or in some cases a flexible sigmoidoscopy, CT scan, or lab work to check for iron deficiency anemia. The goal is to identify the source of bleeding, rule out polyps or cancer, and select the right treatment plan.

Review of your bleeding pattern, bowel habits, and family history
Gentle rectal exam to look for hemorrhoids or fissures
Lab work to check blood counts and iron levels if bleeding is ongoing
Colonoscopy to evaluate the full colon and rectum when indicated
Other imaging or tests based on your symptoms and risk factors

Management focuses on treating the underlying cause, whether benign (hemorrhoids) or more serious (IBD, polyps, cancer). Even when bleeding is mild, persistent or unexplained bleeding usually requires evaluation.

Increasing fiber and fluids to reduce straining and constipation
Topical creams, suppositories, or sitz baths for hemorrhoids and fissures
Treating infections or inflammatory bowel disease when present
Removing polyps during colonoscopy when appropriate
Coordinating with surgeons or cancer specialists if a serious cause is found
Follow-up colonoscopy or clinic visits to monitor your condition
