8. What Happens During an Endoscopy

Preparation for an endoscopy depends on the body part that the doctor is going to examine. For example, for a colonoscopy, the patient will have to clear their bowels. Sometimes, the doctor prescribes antibiotics before the procedure to lower infection risk or stops some medications in the days before the exam. An endoscopy takes between 15 and 45 minutes and is an outpatient procedure in most cases.
