Glucose tolerance is the body's glucose tolerance. 2 hours postprandial blood glucose, more than normal 7.8mmol / L, it has still not reached 11.1mmol / L of diabetes diagnostic criteria (or elevated fasting glucose, diabetes does not meet the diagnostic criteria, namely fasting blood glucose in between 6.2 ~ 7.0) that impaired glucose tolerance (or impaired fasting glucose). This situation can be said to be a normal state over to the diabetes, which some people although it is not diabetes, but the future risk of type 2 diabetes is very high, it can be said that the reserve army of diabetes. According to the study reported that 5-8% this year patients will develop into type 2 diabetes. In addition patients with cardiovascular disease, such as myocardial infarction, angina is also greatly increased the danger.

Human blood sugar levels throughout the day with food, activities, etc. There are fluctuations in general at the time of fasting blood glucose level is more constant. In vivo secretion of insulin and blood glucose number is closely related to increased blood sugar, increase insulin secretion; blood sugar dropped, reducing insulin secretion. The number of insulin secretion, with the body's physiological needs automatically, so that the body glucose levels are maintained within the normal range. This shows that the human body to glucose tolerance have a strong ability, known as the human body normal glucose tolerance. Clinical use of oral or intravenous methods, to a certain amount of glucose to help check the situation in patients with impaired glucose tolerance, saying it was a glucose tolerance test.

When oral or intravenous injection of a certain amount of glucose and diabetic patients (or the disease) of islet β-cell secretion of insulin to deal with the ability of glucose, has shown that as normal as quickly and effectively, and in two hours after OGTT, blood glucose over 7.8 mmol / L (140 mg / dL) or more, increased blood glucose, abnormal glucose tolerance curve, this state is called impaired glucose tolerance.

The reduction of impaired glucose tolerance, diabetes does not mean that there is a certain scope. However, impaired glucose tolerance, and diabetes-prone than normal, which should be highly vigilant.
