POSTPRANDIAL BLOOD-GLUCOSE AND ITS RELATION TO DIABETIC GASTROPARESIS- A COMPARISON OF 2 METHODS

Delayed gastric emptying is known as an important organic cause for br ittle diabetes. We proposed the interval from the start of a meal to t he rise in blood glucose, defined as blood glucose latency (T BG) as a n index for gastric emptying and a non-invasive test for diabetic gast ropathy. In order to validate this test we compared it in 22 type 1 di abetic patients with an established scintigraphic method for the measu rement of gastric half-emptying time (T1/2) and found the following co rrelation: T BG = 4.4 + 0.162 x T1/2; r 0.79, P < 0.001. We therefore suggest measuring the blood glucose latency as a simple non-invasive s creening method.
