The handling of glucose and insulin response before and after weight loss with jejuno-ileal bypass: a preliminary report.

摘要: Glucose and insulin response were studied in morbidly obese patients before after jejuno-ileal bypass. Postbypass studies performed weight loss greater than 30% (9-48 mon). Six-hour oral glucose tolerance tests on 33 bypass 13 of these Thirteen had preoperative intravenous performed, 11 postbypass performed. Plasma insulins drawn concomitantly. Before bypass, fasting blood sugars elevated both intolerance hyperinsulinemia found the tests. After test curves flat (malabsorption effect), while revealed nonsignificant changes but plasma returned toward normal (p 0.05). The massively reverted from Thus does not appear to be a primary etiological factor obesity.
