Colon Polyps (What You Should Know)

Colon polyps are growths that form on the lining of the colon or rectum. While most polyps are harmless, some can develop into colorectal cancer over time. Understanding what colon polyps are, how they're detected, and what you can do to prevent them is crucial for maintaining your gastrointestinal health.

What Are Colon Polyps?

Colon polyps are clumps of cells that form on the lining of the colon. They vary in size and shape, ranging from small, flat lesions to larger, mushroom-like growths. There are several types of colon polyps, with the most common being:

Adenomatous polyps (adenomas): These are the most common type and have the potential to become cancerous over time.

Hyperplastic polyps: Generally small and often considered low risk for developing into cancer.

Inflammatory polyps: Often seen in people with inflammatory bowel disease and typically non-cancerous.

Who Is at Risk?

• Age: Polyps are more common in people over 50.
• Family history: A family history of colon polyps or colorectal cancer increases your risk.
• Lifestyle factors: Diets high in fat, low in fiber, lack of exercise, smoking, and excessive alcohol use contribute to the development of polyps. Red and processed meats may increase the risk of polyps as well.
• Personal history: Having polyps in the past or a history of inflammatory bowel disease also increases risk.

Symptoms of Colon Polyps

Most colon polyps do not cause symptoms, so regular screening is essential. However, larger polyps may cause:

• Rectal bleeding: Blood in your stool or rectal bleeding can signify polyps.
• Change in stool color: Dark or red streaks in the stool may indicate bleeding.
• Change in bowel habits: Constipation, diarrhea, or a change in the frequency of bowel movements lasting more than a week.
• Abdominal pain: Large polyps can obstruct part of the bowel, leading to pain or cramping.

How Are Colon Polyps Detected?

Screening for colon polyps is crucial because they can be present without symptoms. The most effective screening tests include:

• Colonoscopy: A flexible camera is inserted into the rectum to examine the entire colon. If polyps are found, they can be removed during the procedure.
• Sigmoidoscopy: This procedure is like a colonoscopy but only examines the lower part of the colon. 

Preventing Colon Polyps

While it’s not always possible to prevent colon polyps, certain lifestyle changes can reduce your risk:

• Eat a healthy diet: Focus on fruits, vegetables, and whole grains while limiting red meat and processed foods. We offer nutrition counseling from specialized GI-trained dietitians. 
• Exercise regularly: Aim for at least 30 minutes of physical activity most days of the week.
• Don’t smoke or drink excessively: Both smoking and heavy alcohol use are associated with an increased risk of polyps.
• Maintain a healthy weight: Obesity is a risk factor for colon polyps and colorectal cancer.

If you are someone who has had polyps detected, regular surveillance colonoscopy at set intervals is often recommended for future follow up.
