Is colonoscopy painful?

In order to ensure you are both comfortable and safe during the procedure we use MAC anesthesia administered by board certified anesthesiologist. Additionally, we use carbon dioxide (or CO2) instead of air to inflate your colon at our Somerset Ambulatory Surgical Center.

  • During colonoscopy, either CO2 or air is used to inflate the colon so that Dr. Sinha can visualize your colon thoroughly and navigate her scope. 

  • Many patients experience pain or discomfort after colonoscopy as a result of inflated gas retained in the colon. 

  • Using CO2 instead of air reduces the amount of gas retained, resulting in less pain and discomfort for you, less embarrassing gas, and improved satisfaction.
