IKH is a common, but not fully understood, condition in children, and in some the condition may persist in adulthood. In the present study we seek to evaluate the postprandial metabolism in adult subjects diagnosed with IKH through a clinical study including:~two test days, where the subjects completes a) an oral glucose tolerance test (OGTT) and b) a miced meal test (MMT). Before, during and after ingestion of the OGTT/MMT, blood samples will be frequently drawn for the evaluation of plasma glucose, hormones, amino acids and more. During both tests, the subjects will recieve a continuous infusion of primed glucose tracer to further evaluate the glucose metabolism.~a 14-day period where the subjects will lead the usual lives, wearing a continuous glucose monitor (CGM). This will enable us to evaluate long-term differences in plasma glucose levels in IKH.
The project will evaluate 1) the postprandial metabolism and 2) continuous glucose levels in subjects diagnosed with Idiopathic Ketotic Hypoglycemia (IKH)) and healthy control subjects.
