This information will help you get ready for your colonoscopy using polyethylene glycol (MiraLAX ® / Trilyte ® / Golyte ® or Nulyte ®)
A colonoscopy is a test that lets your doctor see inside your colon (large intestine). Your doctor will use a colonoscope (flexible tube with a camera on the end) to see the inside of your colon on a video monitor. During your procedure, your doctor can:
Remove a small sample of tissue (biopsy) for testing
Remove a polyp (growth of tissue)
Take photos of the inside of your colon
Before your procedure, you must follow these instructions carefully. You will need to do a bowel preparation to empty your colon before your procedure. It’s very important that your colon is empty for your colonoscopy. If there’s stool (poop) inside your colon, your doctor may not be able to see polyps or other problems inside your colon and you may have to repeat the procedure. If you have any questions, contact your doctor’s office.
