    Abstract:
    AIMS: This study aimed to determine how insufficiently suppressed endogenous glucose production vs. reduced peripheral glucose uptake contribute to postprandial hyperglycaemia in type 2 diabetes (T2D). METHODS: Eight men with T2D (age: 52+/-7 years; BMI: 26.6+/-2.3 kg/m(2); fasting glycaemia: 7.1+/-1.5 mmol/L) were compared with eight non-diabetic controls (age: 51+/-5 years; BMI: 24.6+/-2.9 kg/m(2); fasting glycaemia: 4.9+/-0.4 mmol/L). Their glucose turnover rates and hepatic glucose cycles were measured by monitoring [2H7]glucose infusion, with m+7 and m+6 enrichment, 3 h before and 4 h after the ingestion of [6,6-2H2]-labelled glucose, while maintaining glycaemia at 10 mmol/L using the pancreatic clamp technique. RESULTS: Of the 700 mg/kg oral glucose load, 71% appeared in the systemic circulation of the T2D patients vs. 63% in the controls (NS). Endogenous glucose production and hepatic glucose cycles did not differ from normal either before or after oral glucose ingestion, while peripheral glucose uptake was reduced by 40% in the T2D group both before (P<0.01) and after (P<0.05) ingestion of oral glucose. CONCLUSION: When T2D patients were compared with non-diabetic subjects with similarly controlled levels of hyperglycaemia after oral glucose ingestion, they essentially differed only in peripheral glucose uptake, whereas endogenous glucose production was apparently unaltered.
