Flexible Sigmoidoscopy Preparation Instructions

This bowel preparation requires a little organization but is an extremely important part of flexible sigmoidoscopy to ensure you have the highest quality exam. Bowel preparation starts days prior to your procedure, as you need to stop taking certain medications or supplements. If you do not follow these directions, your flexible sigmoidoscopy may be cancelled.

Sometimes, procedures result in a cost to the patient. You may check with your insurance company to determine if you will have a cost.
