How Long Does a Colonoscopy Take?
The actual colonoscopy procedure typically lasts between 20 to 60 minutes, depending on various factors such as the presence of polyps, the complexity of the colon's structure, or whether any biopsies are taken. However, patients should plan for the entire visit, including preparation, the procedure itself, and recovery time, to take about two to three hours. The process begins with the administration of sedatives or anesthesia, which can take some time to take effect. Once the patient is sedated, the doctor inserts a colonoscope a flexible tube with a camera into the rectum to carefully examine the colon.
After the procedure is completed, the patient will need to rest and recover from the sedation for about 30 to 60 minutes in a recovery room. During this time, vital signs are monitored to ensure the patient's stability before discharge. Most patients are able to go home the same day, though they will need someone to drive them due to the lingering effects of the sedative. The overall experience, from check-in to leaving the facility, often takes several hours, but the time spent during the actual exam is relatively brief.
