What to Eat 2 Days Before Colonoscopy: Probably Whatever You Want
Most people assume colonoscopy prep means days of dietary misery. The research tells a different story. For generally healthy, average-risk outpatients using a modern split-dose bowel prep, prospective data show no association between what you eat 2 to 3 days before the procedure and how clean your bowel ends up being. That means the restrictive eating many people dread can usually be compressed into a single day, not two or three. Several randomized trials and meta-analyses back this up: extending a low-residue or low-fiber diet beyond one day before the colonoscopy does not improve prep quality. It just makes the whole process harder to follow.
