Negative diabetes test

Have you cut down on your usual amount of food intake?

You mentioned that you were fatigued. The acetone smell may be because you are not eating enough and is a sign that you are not producing enough glucose to breakdown for energy. The body starts breaking down fatty tissue for energy instead. This kind of starvation can occur even in a person who does not have diabetes.

Your test results indicate that you are not diabetic so you could try not missing meals and to consume more energy producing foods such as carbohydrates.

It is possible to have a normal fasting blood sugar but have a raised blood sugar after meals. This is called Impaired Glucose Tolerance (IGT). The standard test for IGT is a 2 hour glucose tolerance test (OGTT). Most GPs won't order it if you have a normal fasting result.

What you need to do is get a meter and monitor your early morning (ie fasting) levels, as well as 5 minutes before meals and 2 hours after the start of a meal. If your post meal numbers are high (over 7.8 at +2 hours) you almost certainly have a problem. I'd also be concerned if you were going into the 7s regularly. If this is the case, go back to your GP with your meter readings and see about further testing. You may be prediabetic even with a normal fasting blood sugar.

If all your readings are normal, however, you can then accept that you are in the clear.
