Prevalence of and risk factors for hypoglycemic symptoms after gastric bypass and sleeve gastrectomy.

Objective: To determine the prevalence of and risk factors for postprandial hypoglycemic symptoms among bariatric surgery patients.

Methods: A questionnaire including the Edinburgh hypoglycemia scale was mailed to patients who underwent either Roux-en-Y gastric bypass (RYGB) or vertical sleeve gastrectomy (VSG) at a single center. Based on the questionnaire, the patients were categorized as having high or low suspicion for post surgical, postprandial hypoglycemic symptoms.
