Rectal Bleeding: Know the Signs and Causes

Rectal bleeding can be an alarming symptom, and it is something no one should ignore or feel embarrassed to discuss. At South Island Gastroenterology Associates in Lawrence, NY, Dr. Steven Kadish and Dr. Jonathan Zinberg encourage patients to bring up any signs of bleeding, no matter how minor they may seem. Often, rectal bleeding is caused by treatable conditions, but it can also signal something more serious that deserves timely evaluation.

What Rectal Bleeding Looks Like

Rectal bleeding can appear in a few different ways. Some people notice bright red blood on toilet tissue after wiping, while others may see blood mixed with stool or even experience darker, tarry stools that indicate bleeding higher up in the digestive tract. It is important to note how the bleeding looks, how often it occurs, and whether it is accompanied by other symptoms such as pain, changes in bowel habits, or fatigue. These details help your gastroenterologist determine the cause.

Common Causes of Rectal Bleeding

Rectal bleeding has many possible sources, and most are not life-threatening. Still, an accurate diagnosis requires a medical evaluation. Common causes include:

Hemorrhoids: Swollen veins in the rectum or anus are the most frequent cause of bright red bleeding. They can be internal or external and are often linked to straining, constipation, or prolonged sitting.

Anal fissures: Small tears in the lining of the anus can cause sharp pain and bleeding during bowel movements. These often result from passing hard stools or chronic constipation.

Diverticulosis: Small pouches in the colon wall can sometimes bleed or become inflamed, leading to noticeable bleeding or abdominal discomfort.

Inflammatory bowel disease: Conditions such as ulcerative colitis and Crohn’s disease can inflame the intestinal lining, leading to bleeding, pain, and diarrhea.

Polyps or colorectal cancer: In some cases, bleeding may result from growths in the colon or rectum. Polyps can be benign, but some may develop into cancer. Regular screening colonoscopies are key to early detection and prevention.

When to See a Gastroenterologist

Even if rectal bleeding seems mild or occasional, it is always worth having it checked, especially if you notice persistent changes in bowel habits, abdominal pain, or unexplained weight loss. Dr. Kadish and Dr. Zinberg use advanced diagnostic tools at the Lawrence, NY, office, including colonoscopy and flexible sigmoidoscopy, to determine the cause of bleeding and recommend appropriate treatment. Early evaluation not only offers peace of mind but can also prevent complications from untreated gastrointestinal conditions.
