Hypoglycemia is an increasingly recognized complication of Roux-en-Y gastric bypass (RYGB)
that is poorly understood and difficult to treat. Investigators hypothesize that after RYGB
some patients have incomplete carbohydrate absorption in the small intestine which leads to
inconsistent glucose levels and hypoglycemia during oral consumption of a meal. Investigators
further hypothesize that pancreatic enzyme supplementation with (Creon) during meals and
snacks will improve carbohydrate absorption and lead to more stable glucose levels in
patients with post-RYGB hypoglycemia.
