Glucose Intolerance

Glucose intolerance is an umbrella term for conditions where blood glucose levels are higher than normal but not yet at the level of type 2 diabetes. These conditions include:

Impaired fasting glucose
Impaired glucose tolerance
Pre-diabetes
Borderline type 2 diabetes

What is glucose intolerance?

Impaired fasting glucose — a fasting blood glucose level of above 6.0 mmol/L
Impaired glucose tolerance — a blood glucose level of over 7.8 mmol/L two hours after consuming 75g of glucose

Glucose intolerance includes anyone with either impaired fasting glucose (IFG) or impaired glucose tolerance (IGT).

Tests

Tests performed to diagnose glucose intolerance include:

Fasting blood plasma glucose test in a laboratory
Oral glucose tolerance test

Symptoms of glucose intolerance

The symptoms are similar to type 2 diabetes — however, you may not feel any symptoms at all. Possible symptoms include:

Increased thirst
Dry mouth
Tiredness
Blurred vision
Frequent urination

Treatment for glucose intolerance

Lifestyle changes are recommended to prevent progression to type 2 diabetes, including healthy eating, regular physical activity, and weight loss where appropriate.
