Core Tip

Core tip: There is a need to improve patients’ experience with bowel preparation process in order to optimize both colonoscopy uptake. Polyethelene glycol (PEG) is the most widely used laxative but many patients do not readily tolerate it because of its taste. We evaluated whether beverage intake preference pattern can be a useful guide for predicting tolerability of bowel preparation laxative in multiple public taste tests. Our study suggested that no demographic or lifestyle factors predicted bowel preparation taste preference for PEG-based preparations. We recommend that patients should taste PEG formulation before flavoring it to assist them in choosing a more tolerable pattern of ingestion.
