Bleeding from the rectum can be scary. You may wonder, “What does this mean?” You are not alone. Many adults worry when they see blood in their stool. In Houston and beyond, GastroDoxs aims to give clear, friendly advice about this common concern. In this guide, we’ll explain:
We’ll also share insights from Dr. Bharat Pothuri, a respected gastroenterologist, and point you to trusted resources. Let’s get started.

Why does blood appear? The color and amount help show the source:
Dr. Bharat Pothuri explains, “Bleeding from the anus can seem urgent. In most cases, it’s due to minor issues like hemorrhoids or an anal fissure. But sometimes, it signals more serious conditions. Early evaluation is key to peace of mind.”
Many causes of rectal bleeding are not life-threatening. Here are the most common reasons for rectal bleeding during a bowel movement:

The question “what causes rectal bleeding in adults” deserves a clear answer. Let’s break down causes by category:
“A careful history and exam help us sort benign from serious causes,” says Dr. Bharat Pothuri. “Screening colonoscopy in Houston clinics can catch polyps before they turn into cancer.”
The short answer: No. Most rectal bleeding does not indicate cancer. However, it’s a warning sign that you should not ignore.
Why? Because early colorectal cancer can bleed even before you notice other symptoms.
Key tip: If you’re over 45 (or 40 with risk factors), get regular screenings. The American Cancer Society recommends that adults at average risk start screening at 45.
