Gw mau tau Glucose tolerance testing (GTT) dari Kerintangan insulin. Jelasin dalam bahasa melayu

During a glucose tolerance test, which may be used to diagnose diabetes mellitus, a fasting patient takes a 75 gram oral dose of glucose. Blood glucose levels are then measured over the following 2 hours.

Interpretation is based on WHO guidelines. After 2 hours a Glycemia less than 7.8 mmol/L (140 mg/dl) is considered normal, a glycemia of between 7.8 to 11.0 mmol/dl (140 to 197 mg/dl) is considered as Impaired Glucose Tolerance (IGT)  and a glycemia of greater than or equal to 11.1 mmol/dl (200 mg/dl) is considered Diabetes Mellitus.

An OGTT can be normal or mildly abnormal in simple insulin resistance. Often, there are raised glucose levels in the early measurements, reflecting the loss of a postprandial (after the meal) peak in insulin production. Extension of the testing (for several more hours) may reveal a hypoglycemic "dip," which is a result of an overshoot in insulin production after the failure of the physiologic postprandial insulin response.
