What is Rectal Bleeding?

Rectal bleeding refers to blood passing through the rectum or anus. It can vary in color, amount, and frequency. The presence of blood can be alarming and may indicate a range of conditions, from minor to serious. The color and type of bleeding can offer clues about the source of the problem:

 

Bright Red Blood: Often indicates bleeding from the lower part of the digestive tract, such as hemorrhoids or anal fissures.

Dark Red or Maroon Blood: May suggest bleeding from higher up in the colon or rectum.

Black, Tarry Stool: Typically indicates bleeding from the upper digestive tract, such as the stomach or small intestine.

Common Causes of Rectal Bleeding

Several conditions can cause rectal bleeding. Understanding these causes can help you identify potential issues and seek appropriate treatment. Here are some common causes:

 

1. Hemorrhoids

Hemorrhoids are swollen blood vessels in the rectal area that can cause bleeding during bowel movements. They can be internal (inside the rectum) or external (under the skin around the anus). Symptoms may include itching, pain, and bright red blood on toilet paper or stool.

 

2. Anal Fissures

Anal fissures are small tears in the lining of the anus that can cause bleeding and significant pain during and after bowel movements. They are often caused by passing large or hard stools.

 

3. Diverticulosis and Diverticulitis

Diverticulosis occurs when small pouches (diverticula) form in the colon wall. If these pouches become inflamed or infected (diverticulitis), they can cause rectal bleeding and abdominal pain.

 

4. Inflammatory Bowel Disease (IBD)

Inflammatory bowel diseases, such as Crohn’s disease and ulcerative colitis, can lead to rectal bleeding. These conditions cause inflammation and ulcers in the digestive tract, resulting in symptoms like bleeding, diarrhea, and abdominal pain.

 

5. Colorectal Polyps and Cancer

Colorectal polyps are growths on the lining of the colon or rectum that can sometimes bleed. While many polyps are benign, some can develop into colorectal cancer, which can also cause rectal bleeding.

 

6. Peptic Ulcers

Peptic ulcers are sores that develop on the lining of the stomach, small intestine, or esophagus. They can cause bleeding in the upper digestive tract, leading to black, tarry stools.

 

7. Gastrointestinal Infections

Certain infections can cause inflammation and bleeding in the GI tract. These may be caused by bacteria, viruses, or parasites.

 

Diagnostic Procedures for Rectal Bleeding

If you experience rectal bleeding, it’s essential to consult a gastroenterologist to determine the underlying cause. At Manhattan Gastroenterology, we use a variety of diagnostic tools to evaluate and diagnose the issue:

 

1. Medical History and Physical Examination

Your gastroenterologist will start by taking a detailed medical history and performing a physical examination. This helps identify potential causes based on your symptoms, lifestyle, and any relevant medical conditions.

 

2. Colonoscopy

A colonoscopy is a procedure in which a flexible tube with a camera (colonoscope) is inserted through the rectum to examine the colon and rectum. It allows for the direct visualization of the digestive tract and the removal of polyps or biopsy samples if needed. Colonoscopy is a crucial diagnostic tool for evaluating rectal bleeding and assessing conditions like colorectal cancer.

 

3. Endoscopy

An endoscopy involves using a flexible tube with a camera (endoscope) to examine the upper digestive tract, including the esophagus, stomach, and duodenum. This procedure is useful for diagnosing conditions like peptic ulcers and gastrointestinal bleeding.

 

4. Imaging Studies

Imaging studies, such as CT scans or MRI, may be used to visualize the gastrointestinal tract and identify abnormalities that may be causing rectal bleeding.

 

5. Stool Tests

Stool tests can help identify the presence of blood, infections, or other abnormalities in the digestive tract. These tests are often used in conjunction with other diagnostic procedures.
