Colonoscopy Prep

Preparing for Your Colonoscopy: What to Expect

Once you’ve scheduled your colonoscopy, the next step is to prepare your bowels for the procedure. Proper preparation is crucial to ensure a successful screening. If your colon isn’t thoroughly cleaned, your healthcare provider may have difficulty examining it.

Preparation begins about a week before your appointment. You may need to adjust your diet and medications 
based on your provider's instructions. Typically, the process includes:

  • Medication Changes: You will be instructed to stop or adjust medications up to 7 days before your procedure if you are taking certain medications such as blood thinners, weight loss medications, and diabetic medications. For a complete list, see the medication table below. If you are taking any of these medications and have not received instructions, please call our office at (971)254-9884.
  • Diet Changes: Start with a low-fiber diet two to three days before the procedure. On the day before, switch to a clear liquid diet
  • Bowel Prep: The afternoon or evening prior to your colonoscopy, you’ll take a prescribed laxative solution to cleanse your colon. The specific timing and instructions will depend on your preparation formula and the  time of your procedure. 

Your healthcare provider will give you detailed, personalized instructions to guide you through the process. Following these steps carefully will help ensure your colonoscopy goes smoothly.
