AI Overview
A colonoscopy is a standard, minimally invasive procedure used to examine the lining of your large intestine (colon and rectum) to screen for cancer, investigate symptoms, or remove precancerous polyps. The procedure itself takes only 15 to 30 minutes, and because of the sedation used, it is typically painless. [1, 2, 3, 4, 5]
Before the Procedure
- Dietary Changes: You will need to switch to a low-fiber diet a few days before. The day before, you will be restricted to a clear liquid diet (water, broth, black coffee, apple juice).
- Bowel Prep: The evening before (and possibly the morning of), you will consume a special prescription laxative solution. This "prep" cleans out your colon so the doctor can clearly see the lining. Medication Review: Inform your doctor about any medications or supplements you take, particularly blood thinners or diabetes medication, as these may need to be adjusted.
During the Procedure
- Arrival & Setup: You will change into a hospital gown, and a nurse will start an IV to administer sedative or anesthesia medications.
- The Process: You will lie on your side while the doctor inserts a long, thin, flexible tube (the colonoscope) into your rectum. The tube contains a tiny camera and pumps a small amount of air to inflate the colon for visibility.
- Action Taken: If the doctor spots polyps or abnormal tissue, they will usually remove them or take small biopsy samples right then and there. [1, 2, 3, 4, 5, 6]
Recovery & Aftercare
- Waking Up: You will spend about 30 to 60 minutes in a recovery room as the sedative wears off. You may feel a little bloated or have mild cramping from the air used during the exam.
- Transportation: Because of the lingering effects of the anesthesia, you must have a friend or family member drive you home. You cannot drive or operate machinery for 24 hours.
