Colonoscopy 

A colonoscopy is a medical procedure that allows your doctor to examine the inner lining of your colon (large intestine). During the procedure, a flexible tube with a small camera, called a colonoscope, is gently inserted through the rectum to check for any signs of conditions like colorectal cancer, polyps, or inflammation. This test is key for early detection of issues that can affect your digestive health. According to the American Cancer Society, the most effective way to reduce your risk of colorectal cancer is to get screened routinely, starting at age 45. If you have a family history of polyps or colon cancer, your doctor may recommend earlier screening. Make sure to consult with your physician to determine if you’re eligible for early screening.

What are the Benefits of a Colonoscopy?

A colonoscopy offers several important benefits: 

  • Early Detection: Colonoscopy can detect colon cancer early, which makes it easier to treat and offers a higher chance of recovery. 
  • Polyp Detection and Removal: A colonoscopy can screen for colon cancer and treat colon polyps. Since most colon cancers begin as harmless polyps, they can be removed during the procedure, preventing them from becoming cancerous. 
  • Peace of Mind: A clean colonoscopy result means you’re in good digestive health, giving you reassurance for years to come. 

What are the Risks of a Colonoscopy?

Though colonoscopies are very safe, like any procedure, there are some risks to be aware of: 

  • Bleeding: Rarely, bleeding may occur, especially if polyps are removed. However, significant bleeding, which might require a blood transfusion or hospitalization, is very uncommon. 
  • Perforation: There is a small chance of a tear in the colon lining. 
  • Discomfort: You may feel bloated or experience mild cramping after the procedure, but these symptoms typically go away quickly. 

Your doctor at GI Partners of Illinois will discuss all possible risks with you and take steps to ensure your safety throughout the procedure. It is very important that you contact your doctor’s office immediately if symptoms arise after the procedure, such as worsening abdominal pain, bleeding, or fever. 

Like any other test, a colonoscopy is not perfect. There is a small and accepted risk that abnormalities, including polyps and cancers, can be missed at the time of the exam. It is important to continue to follow up with your doctor at GI Partners of Illinois as instructed and inform them of any new or persistent symptoms. 

What Should I Expect During a Colonoscopy?

  • Before the Procedure: You will be given instructions on how to prepare your bowel, which usually involves taking a special laxative the day before. You may also be asked to avoid certain foods. 
  • During the Procedure: You will receive a mild sedative to help you relax. The doctor will gently insert the colonoscope, which will allow them to see the inside of your colon on a screen. Depending on the findings of the exam, several things can be done at the time of the procedure, including biopsies, the removal of polyps, and the control of bleeding. 
  • After the Procedure: You’ll spend some time in recovery as the sedative wears off. It’s common to feel a little bloated or gassy, but this will pass soon. Most people can go home the same day and return to normal activities within 24 hours. 

What are the Alternatives to a Colonoscopy?

There are a few alternative screening methods to colonoscopy, though they may not be as thorough: 

  • Stool Tests: These can detect hidden blood or abnormal DNA in your stool, which may indicate cancer. 
  • Virtual Colonoscopy: A non-invasive scan of the colon, but if abnormalities are found, a traditional colonoscopy is still needed. 
  • Flexible Sigmoidoscopy: This checks only the lower part of the colon but doesn’t provide as complete a picture as a colonoscopy. 

Your doctor at GI Partners of Illinois can help you choose the right screening method based on your health needs.
