The Glucose Tolerance Curve indicates our risk for Type 2 Diabetes

The Glucose Tolerance Curve indicates our risk for Type 2 Diabetes

The Glucose Tolerance Curve tells us how are cells are responding to glucose, as well as our risk of getting insulin resistance or developing Pre-Diabetes or Type 2 Diabetes. In most cases, this test is done to pregnant women to check if they have Gestational Diabetes. Diagnoses will be made depending on the following results.

Normal Glucose Tolerance: A person is considered to have a normal glucose insulin response, when all of their blood glucose levels lie below 200 mg/dl during the first 2 hours and their glycemia levels are lower than 140 mg/dl 2 hours after having ingested the glucose solution.

Abnormal Glucose Tolerance: A person is considered to have an abnormal glucose insulin response, i.e. they are glucose intolerant, when their fasting blood glucose levels are greater than 100 mg/dl and less than 115 mg/dl, but their blood sugar level is between 140 mg/dl and 199 mg/dL 2 hours after ingesting the glucose solution. In this case, the person may have insulin resistance or pre-diabetes and in either case, a Diabetes diagnosis could still be prevented.

Diabetes: It is considered that a person has diabetes when their fasting glucose level is higher than 126 mg/dl and their glycemia levels 2 hours after ingesting the glucose solution are greater than 200 mg/dl.

Gestational Diabetes: A woman has Gestational Diabetes when her blood glucose level is 180 mg/dl or more, one hour after ingesting the glucose solution, 155mg/dl or more after 2 hours and 140 mg/dl or more after 3 hours.

We need to remember that whichever the results shown in the Glucose Tolerance Curve are, cell insulin sensitivity can be recovered, by making them less insulin resistant or glucose intolerant. The more sensitivity to insulin signals our cells recover, the lower the risk of them becoming glucose intolerant is. This will also lower our risk of developing Pre-Diabetes, Type 2 Diabetes and Gestational Diabetes in women.

Other recommendations on the Glucose Tolerance Curve


The Glucose Curve Tolerance is a very important test because it indicates how your insulin reacts to glucose intake to determine your cell’s sensitivity degree to insulin signaling and how it metabolizes glucose to use it as fuel, and it won’t remain at high levels in the bloodstream. The Glucose Tolerance Curve will tell us if we have a normal or abnormal glucose tolerance and will also help diagnose whether a person has Type 2 Diabetes.

Reducing the risk factors and detecting the problem before Type 2 Diabetes appears is a key factor so we can have a better quality of life. Therefore it’s very important for us to make all the necessary lifestyle changes so we can reduce our risk factors; Additionally we should also request glucose and Hemoglobin A1c tests at least once a year and get a Glucose Tolerance test if we suspect we’re at high risk.

Being well informed about the risk factors for developing Diabetes and acting immediately, taking all necessary steps to reduce or avoid it, will help us prevent a Diabetes diagnosis.

In Diabetes Up to Date you’ll find all the information you need so you can prevent or delay a Type 2 Diabetes diagnosis, which will allow you to enjoy a healthier, productive and happy life.
