Bowel Prep Instructions/Checklist for Colonoscopy


Our Gastroenterology Clinic in Fort Walton Beach provides colonoscopy screenings as a preventive measure to reduce your risk of colon cancer. A colonoscopy screening is a procedure for individuals who are not experiencing any pain or symptoms, and is helpful in the diagnosis or evaluation of various GI disorders, including colon cancer. During the colonoscopy, your gastroenterologist can both identify and remove precancerous polyps.

Patients with a family history of colon cancer/colon polyps should schedule a screening colonoscopy at age 40. If you have no family history of colon cancer, you should schedule a screening colonoscopy at age 45. If you are experiencing any gastrointestinal symptoms, you should contact your primary care physician immediately.

The White-Wilson gastroenterologists perform routine colonoscopy screenings at the Emerald Coast Surgery Center. A screening colonoscopy is an outpatient procedure, and patients can expect to be home that day.
