Rectal bleeding can be an alarming symptom, whether you notice a few drops of blood on the toilet paper or more significant bleeding after a bowel movement. While not every case indicates something serious, it’s important not to ignore it.
Understanding the potential causes of rectal bleeding and knowing when to seek professional colorectal care can make all the difference for your health and peace of mind.
Common Causes of Rectal Bleeding
Rectal bleeding can originate from several areas in the lower digestive tract, and its cause can range from mild irritation to more serious medical conditions. Some of the most common causes include:
1. Hemorrhoids
Hemorrhoids—swollen veins in the rectum or anus—are the most common cause of rectal bleeding. They may result from chronic constipation, straining during bowel movements, pregnancy, or prolonged sitting. Bleeding from hemorrhoids is typically bright red and may be seen on toilet paper or in the toilet bowl.
2. Anal Fissures
An anal fissure is a small tear in the lining of the anus, often caused by passing a hard stool. The pain can be sharp during bowel movements, and the bleeding is usually minimal but noticeable. Fissures often heal on their own with stool softeners, increased fiber intake, and good hydration, but persistent pain should be evaluated by a specialist.
3. Inflammatory Bowel Disease (IBD)
Conditions such as Crohn’s disease and ulcerative colitis can cause inflammation and ulceration of the intestinal lining, leading to rectal bleeding. People with IBD may also experience abdominal pain, diarrhea, and fatigue. Managing IBD often requires long-term medical treatment under the care of a colorectal specialist.
4. Polyps and Colorectal Cancer
Polyps are growths that form in the lining of the colon or rectum. While most are benign, some can develop into colorectal cancer if left untreated. Early colorectal cancer may cause rectal bleeding without other symptoms, which is why regular screenings—especially after age 45—are essential for prevention and early detection.
5. Gastrointestinal Infections
Certain infections caused by bacteria, viruses, or parasites can irritate the intestinal lining and cause inflammation, diarrhea, and bleeding. These infections are often resolved with proper hydration and rest, but persistent symptoms should be evaluated to rule out more serious issues.
6. Diverticular Disease
Diverticulosis occurs when small pouches form in the colon wall. When these pouches become inflamed or infected, a condition called diverticulitis, rectal bleeding can occur. This type of bleeding can sometimes be heavy and may require immediate medical attention.
When Should You Worry About Rectal Bleeding?
Even though rectal bleeding is common, it should never be dismissed, especially if:
- The bleeding is recurrent or heavy
- You experience pain, fatigue, or unintentional weight loss
- You notice changes in bowel habits, such as persistent constipation or diarrhea
- The blood appears dark or mixed with stool (which may suggest bleeding higher in the digestive tract)
In these cases, it’s important to schedule a visit with a colorectal specialist as soon as possible. Early diagnosis can rule out serious conditions and ensure you get the right treatment quickly.
