Colonic Polyps

Colonic polyps are growths on the inner lining of the colon (large intestine) or rectum. They are usually small, non-cancerous (benign), and can be found in people of all ages. However, they are more common in people over 50 years old.

Types of Colonic Polyps

There are several types of colonic polyps, including:

• Hyperplastic polyps: These are the most common type and are usually small and non-cancerous.
• Adenomatous polyps (adenomas): These are the second most common type and have a higher risk of becoming cancerous over time.
• Sessile serrated polyps: These are less common but have a higher risk of becoming cancerous than hyperplastic polyps.
• Inflammatory polyps: These occur in people with inflammatory bowel disease, such as ulcerative colitis or Crohn's disease.

Causes and Risk Factors

The exact cause of colonic polyps is not known, but several factors can increase the risk of developing them, including:

• Age: Polyps are more common in people over 50 years old.
• Family history: Having a family history of colon cancer or polyps increases the risk.
• Diet: A diet high in fat and low in fiber may increase the risk.
• Lack of physical activity: A sedentary lifestyle can increase the risk.
• Smoking: Smoking can increase the risk of developing polyps.

Symptoms

Most colonic polyps do not cause symptoms, but some people may experience:

• Blood in the stool or black stools
• Diarrhea or constipation
• Abdominal pain or cramping
• Fatigue or weakness due to anemia from bleeding polyps

Diagnosis and Treatment

Colonic polyps are usually diagnosed through:

• Colonoscopy: A procedure where a flexible tube with a camera is inserted into the colon to visualize the inner lining.
• Sigmoidoscopy: A procedure similar to colonoscopy, but only examines the lower part of the colon and rectum.
• Virtual colonoscopy (CT colonography): A non-invasive test that uses CT scans to visualize the colon.

Treatment for colonic polyps usually involves:

• Removal of the polyp during a colonoscopy or sigmoidoscopy
• Surgical removal of the affected part of the colon (colectomy): In rare cases where the polyp is large or cancerous.

Prevention

To reduce the risk of developing colonic polyps, it is recommended to:

• Eat a healthy diet high in fiber and low in fat
• Exercise regularly
• Avoid smoking
• Get regular colon cancer screenings starting at age 50 (or earlier if there is a family history)
