Hypoglycemia and Glucagon Response in CF

The goal of this clinical trial is to investigate the etiopathogenesis of isolated hypoglycemia and hypoglycemia with abnormal glucose tolerance in children with Cystic Fibrosis (CF) and to evaluate the role of glucagon and pancreatic insufficiency on hypoglycemia in CF. The main questions it aims to answer are: 1. Do isolated hypoglycemia and hypoglycemia with abnormal glucose tolerance have different etiopathogenesis? 2. What is the role of pancreatic insufficiency in these two conditions? Participants were asked to perform 3-h OGTT and to take blood samples. Researchers compared with healthy peers to see if there is isolated hypoglycemia in OGTT and how is the glucagon response to OGTT in healthy peers.
