Before Colonoscopy Screening: Bowel Prep and Clear Liquid Diet Instructions
Summary
A colonoscopy is a routine exam that helps doctors check the health of your large intestine. To ensure accurate results, you'll need to prepare by following a specific diet and using a laxative solution. This guide will walk you through each step so you can feel ready and confident before your procedure.
What Is This & Why It Matters
A colonoscopy is a medical test that allows your doctor to see inside your large intestine. It helps in detecting any problems like polyps or signs of cancer early on. Preparing for this test involves cleaning out your bowel, which means you'll need to follow a clear liquid diet and take a special laxative. This preparation ensures that your doctor can get a clear view during the exam.
What You Should Do
- Start your clear liquid diet 24 hours before the procedure. This includes water, broth, apple juice, and gelatin.
- Drink plenty of fluids to stay hydrated. Aim for at least 8-10 glasses of clear liquids.
- Begin the laxative solution as directed on the packet the evening before your colonoscopy.
- Stop eating or drinking anything after midnight before the procedure (NPO status).
- Arrange for someone to drive you home after the procedure because sedation will be used.
- Remove any dentures, jewelry, or piercings before arriving at the clinic.
- Wear comfortable clothing on the day of your procedure.
- Return to the clinic at the scheduled time on the morning of your colonoscopy.
What You Should NOT Do
- Do not eat any solid foods 24 hours before your procedure.
- Avoid drinks with red or purple coloring, as they can affect test results.
- Do not drink alcohol while preparing for your colonoscopy.
- Refrain from taking any aspirin or blood thinners unless instructed by your doctor.
- Avoid wearing lotions or perfumes on the day of your procedure.
