What is Colonoscopy?

A colonoscopy is a medical procedure that allows doctors to view the inside of the large intestine (colon) and rectum. Using a thin, flexible tube with a small camera, your GI specialist can carefully examine these areas for any signs of abnormal growth or conditions. 

What Problems Can Colonoscopy Detect?

A colonoscopy can help detect a variety of digestive health issues, such as: 

  • Polyps: Small growths or polyps that can develop into colorectal cancer if untreated. 
  • Colorectal Cancer: Early detection of colon cancer is critical for successful treatment. 
  • Ulcers and Inflammation: Indicates conditions like ulcerative colitis or Crohn’s disease. 
  • Diverticulosis: Small pouches in the colon wall that can lead to complications. 

Regular colonoscopy screenings are an effective tool in identifying these issues before symptoms even start. 

When is Colonoscopy Used?

Your doctor may recommend a colonoscopy if you: 

  • Are 45 or older for routine colorectal cancer screening. 
  • Have a family history of colorectal cancer or polyps. 
  • Are experiencing digestive symptoms like blood in your stool, abdominal pain, or unexplained weight loss. 

Colonoscopy can be both a preventive and diagnostic procedure, helping to protect your health proactively. 

How to Prepare for Colonoscopy

Preparing for a colonoscopy involves following a special diet and cleansing your bowel. Here’s a quick guide: 

Pre-Colonoscopy Diet

Your doctor may ask you to follow a clear liquid diet the day before the procedure.

Bowel Prep

You will likely take a prescribed laxative to ensure the colon is completely empty.

How is Colonoscopy Performed?

You’ll be given sedation to help you relax.

The doctor will guide a colonoscope into your rectum and through the large intestine, allowing for a thorough examination.

If polyps or abnormal tissue are found, they may be removed or sampled for further testing.

The procedure is safe and typically completed in about 30-60 minutes. 

How Long Does It Take to Recover from Colonoscopy?

Most patients recover quickly from a colonoscopy. After the procedure: 

  • You may spend some time in a recovery area as the sedation wears off. 
  • You may experience mild cramping or gas but can resume regular activities the next day. 
  • Plan to have someone drive you home due to the sedation. 

Complete colonoscopy recovery is usually swift, allowing you to get back to your routine soon. 

What Are the Risks Associated with Colonoscopy?

While colonoscopy is generally safe, it does carry some risks, including: 

  • Bleeding: Rarely, some bleeding may occur, especially if a biopsy was performed. 
  • Perforation: A very rare risk where the colon may be punctured. 
  • Reactions to Sedation: These are uncommon but can happen. 

Our GI specialists take every precaution to ensure your safety and comfort.
