A colonoscopy is a medical exam that allows doctors to view the inner lining of your large intestine. Doctors recommend this procedure to screen for colon cancer or to find the cause of unexplained abdominal pain. You must follow strict preparation steps before you have the exam. Preparation cleans out your colon, and this clear view helps your doctor spot any problems.
Understanding Colonoscopies
During a colonoscopy, a doctor inserts a thin tube into your rectum to inspect your colon. The tube features a tiny camera, and this device sends video images to a monitor. You will receive medication to help you relax during the entire exam. Most patients sleep through the process because the sedative works quickly.
The exam typically takes about thirty minutes to complete from start to finish. The doctor looks for polyps, and they will remove any abnormal growths during the colonoscopy. Because these growths can become cancerous, removing them protects your long-term health. You will wake up in a recovery room shortly after the test ends.
Explaining Preparation
A bowel prep kit is a prescribed laxative that empties your digestive tract completely. You will mix the medication with water, and you will drink the liquid at certain intervals. The doctor will prescribe a kit based on your personal medical history.
There are a few common types of prep kits available:
- Liquid solutions that you drink in large volumes.
- Powder packets that you mix with flavored beverages.
- Pill-based prep kits that require drinking plenty of water.
These options clear your bowels, and this helps the doctor to have a better view of the colon during your procedure. Your physician can advise you on which option works for your body.
Adjusting Diet
You need to change your diet a few days before your appointment date. Doctors tell patients to eat low-fiber foods, and this change reduces the amount of solid waste you will need to pass during your preparation. You should avoid nuts, seeds, and raw vegetables because they digest very slowly. You can drink regular water alongside your modified meals.
Low-fiber food choices include:
- white bread
- eggs
- chicken
- fish
- white pasta
- tofu
- smooth peanut butter
When the day before the procedure arrives, you must switch to a clear liquid diet. Colored foods can block the camera’s view or cause confusion about the test results, so you should only consume fluids that are transparent. Approved clear liquids include apple juice, chicken broth, and sports drinks. You cannot drink anything red or purple since these colors mimic blood.
Managing Expectations
Many patients still experience bowel movements on the morning of their scheduled procedure. Your body might continue to pass liquid, and if it is yellow and mostly clear, your prep worked correctly. If you pass solid waste, you must call your doctor right away for guidance. You might need to reschedule the exam if your colon is not clean.
