Contribution to Postprandial Hyperglycemia and Effect on Initial Splanchnic Glucose Clearance of Hepatic Glucose Cycling in Glucose-Intolerant or NIDDM Patients

The results indicate that postprandial hyperglycemia in diabetic and glucose-intolerant patients is not due to enhanced hepatic glucose cycling or a lack of uptake of ingested glucose by the splanchnic bed but rather to excessive release of glucose byThe liver coupled with a failure of extrahepatic tissues to appropriately increase glucose disposal.
