Also known as: Hematochezia
Rectal bleeding is the passage of blood from the anus, seen on toilet paper, in the bowl, or mixed with stool. While often caused by hemorrhoids, it always warrants evaluation.
Rectal bleeding is common and causes significant anxiety. Bright red blood typically indicates a lower GI source (rectum, anus, colon), while dark or black blood suggests an upper GI source.
Hemorrhoids are the most common cause of minor rectal bleeding, especially in adults who strain with bowel movements. Anal fissures cause bleeding with pain during defecation.
While most rectal bleeding is benign, it should always be evaluated — particularly in those over 40 or with risk factors for colorectal cancer.
There are several possible reasons you may be experiencing Rectal Bleeding. Here are the most common ones.
Swollen rectal blood vessels that bleed with straining. Usually bright red, painless bleeding.
Small tear in the anal lining causing bright red bleeding with sharp pain during bowel movements.
Small pouches in the colon wall that can bleed suddenly and painlessly, sometimes significantly.
Growths on the colon lining that may bleed intermittently. Some types can become cancerous.
These approaches may help manage rectal bleeding at home. Always consult a healthcare provider if symptoms persist or worsen.
Fiber softens stool and reduces straining, helping hemorrhoids and fissures heal.
Sitting in warm water for 10-15 minutes soothes hemorrhoids and fissures.
Drinking enough water keeps stool soft and prevents straining.
Digital rectal exam, anoscopy, colonoscopy for those over 40 or with risk factors, and stool tests.
Seek immediate care if bleeding is heavy, accompanied by dizziness or fainting, if stool is black or tarry, or if bleeding is new in someone over 40.
Steps you can take to reduce the likelihood of experiencing rectal bleeding.
Eat a high-fiber diet
Stay well hydrated
Avoid straining during bowel movements
