The Effect of GLP-1 on Glucose Uptake in the Brain and Heart in Healthy Men

Summary

Type 2 diabetes mellitus, T2D is a disease characterized by an immense growing prevalence world wide with an increased risk of myocardial infarction and stroke. GLP-1 has convincing effects on the high glucose levels in type 2 diabetic patients and is well tolerated. New animal studies indicate a protective effect of GLP-1 in the brain and the heart. The mechanism behind this is yet not known. The study hypothesis is that GLP-1 will stimulate glucose-uptake in the brain and heart independent of insulin and thereby exert its protective effects.
