Glucose tolerance tests: What exactly do they involve?
Oral glucose tolerance tests (OGTT) are used to measure how well the body can process a larger amount of sugar. If the blood sugar measured in the test is above a certain level, this could be a sign that sugar is not being absorbed enough by the body’s cells. Diabetes or gestational diabetes might be at the root of this problem.
In gestational diabetes, blood sugar levels are often higher due to changes in the metabolism during pregnancy – but they usually come back down again after the child is born.
