How to Know If Your Rectal Bleeding Is Serious

Discovering blood after a bowel movement can feel alarming. You may wonder: “Is this normal?” or “Should I panic?” At Gastrodoxs.com, we believe everyone deserves clear, friendly guidance. In this post, Dr. Bharat Pothuri, a Houston gastroenterologist, walks you through the key signs that rectal bleeding might be serious—and when it’s OK to stay calm.
“I tell my patients at the Texas Medical Center that not all bleeding is an emergency,” says Dr. Pothuri. “But prompt attention can prevent complications.”

In this guide, you’ll learn:

Section 1: Understanding Rectal Bleeding

What is rectal bleeding?

Rectal bleeding means any blood that passes from your anus. You may notice:

Why it happens

Blood appears when tiny vessels in your lower digestive tract break or swell. Common sites include the rectum, anus, or the end of your colon.

Section 2: Common (Usually Mild) Causes

1. Hemorrhoids

2. Anal fissures

Dr. Pothuri notes, “In many Houston clinics, these benign causes account for over half of cases.”

When to worry about blood in stool?

“If you see more than a teaspoon of blood, or if it continues for two days,” says Dr. Pothuri, “it’s time to call your doctor.”

Frequently Asked Questions

1. What if I see just a little blood on toilet paper?

Small streaks often come from hemorrhoids or anal fissures. Watch for changes and follow at-home care.

2. Can constipation cause rectal bleeding?

Yes. Straining hard stools can tear delicate tissues. A fiber-rich diet helps prevent this.

3. When should I worry about blood in stool?

If bleeding recurs for more than two days, or if you pass more than a teaspoon of blood, see your doctor.

4. I have painless bright red blood in stool. Do I need a colonoscopy?

Your doctor may recommend a colonoscopy to rule out serious causes, especially if you’re over 45.

5. Can medication cause rectal bleeding?

Blood thinners (like warfarin) may increase bleeding risk. Always talk to your prescriber.

6. How is internal hemorrhoid bleeding treated?

Mild cases improve with lifestyle changes. Severe ones may need rubber band ligation or other office treatments.

7. Is black, tarry stool an emergency?

Yes. Dark stool often means the bleed is higher up in your GI tract. Seek care immediately.

8. Are children at risk for rectal bleeding?

Children can get fissures or infections. Always have pediatric bleeding checked by a doctor.

9. Where can I find a trusted Houston gastroenterologist?

Look for board-certified specialists at Texas Medical Center or Houston Methodist hospitals.
