                                Approximately 1 in 4 colonoscopies result in a suboptimal prep, which can hinder accurate visualization of the colon lining and lead to repeat procedures. A successful prep relies heavily on a low-fiber diet in the days leading up to the procedure, and this includes careful consideration of foods like a ham sandwich.
