Dietary, Medication, and Endoscopic Interventions for Post-Bariatric Hypoglycemia

Post-bariatric hypoglycemia (PBH) is a complication of upper gastrointestinal surgery that causes recurrent episodes of low blood sugar after eating and can substantially impair quality of life. Currently, there are no approved therapies specifically indicated for PBH. The purpose of this study is to better understand the physiological mechanisms underlying PBH and to evaluate three therapeutic approaches that may reduce hypoglycemia: dietary modification, treatment with a GLP-1 receptor agonist or dual GIP/GLP-1 receptor agonist, and transoral outlet reduction (TORe). Participants will undergo detailed metabolic testing, including continuous glucose monitoring, mixed meal tolerance testing, and gastric emptying scintigraphy, to determine how these interventions affect gastric emptying, glucose regulation, insulin secretion, gut hormone responses, and hypoglycemia.

Pasireotide s.c. in Patients With Post-Bariatric Hypoglycaemia

The Total duration of trial participation for each participant with post-bariatric hypoglycemia will be a maximum of 59 weeks, with the following duration of trial periods * 19 weeks for the Core Phase. It is composed of: * a Screening period: a maximum of 3 weeks * a Run-in period (no treatment): 4 weeks * a Blinded Treatment Phase: 12 weeks * 36 weeks Extension Phase = an open-label Treatment period * 4 weeks for the safety follow-up period (without any treatment).

Role of Nutrient Transit in Hyperinsulinemic Hypoglycemia

Severe hypoglycemia (low blood sugar)after gastric bypass surgery is an increasingly recognized condition, characterized by symptoms of hypoglycemia after eating and inappropriately elevated insulin concentrations that occur at the time of hypoglycemia. Severe hypoglycemia can be dangerous and debilitating and can also impact cognitive function. At the moment no medical therapies have been developed for this disorder. Determining why some but not other patients develop this condition would allow for improved prediction, prevention, and treatment approaches. The purpose of the study is to understand the physiological changes observed in those patients who undergo gastric bypass and develop symptomatic hypoglycemia.
