During an office visit, the team will update your medical and surgical history and medications. If possible, bring an updated list of medications, medical conditions, and a copy of your most recent colonoscopy. If you have never had a colonoscopy, the surgeon will determine whether one is needed. Before the visit, try to jot down a timeline of your symptoms and what you have tried so far to for treatment. This will be very helpful for your colorectal surgeon.
