Gestational diabetes often does not show any symptoms even when doing a glucose tolerance test during pregnancy. However, high gestational diabetes index can cause very serious effects for both mother and fetus.

Oral glucose tolerance test to diagnose diabetes will measure blood glucose index at 3 times: when fasting overnight, 1 hour and 2 hours after drinking sugar water solution.

Normally, the amount of glucose will be at a certain level enough to maintain metabolism in the body, but sometimes the glucose increases abnormally, indicating a medical condition such as diabetes. The blood sugar test index will help specifically assess the amount of sugar in the body as well as support the diagnosis of problems that the body has.
