Post-bariatric surgery patients, particularly those undergoing Roux-en-Y gastric bypass (RYGB) or biliopancreatic diversion (BPD), are at high risk for postprandial hyperinsulinemic hypoglycemia (PHG) due to accelerated carbohydrate delivery to the small intestine, which triggers excessive GLP-1 secretion and subsequent insulin hypersecretion.

If you have had gastric bypass surgery, be aware that eating simple sugars can cause a dangerous drop in blood sugar 2-3 hours later. This is caused by your body overproducing insulin in response to fast-absorbing carbs. Manage this by strictly limiting simple sugars and focusing on complex carbohydrates and fiber to slow absorption.
