What usually happens next

It's usually confirmed by repeating it or adding an HbA1c, then rechecked about once a year.

In the Diabetes Prevention Program, people with prediabetes who lost about 7% of their weight and walked about 150 minutes a week cut their chance of developing diabetes by 58% over about 3 years.

What a high fasting glucose usually means, and its common causes

When a fasting glucose can read wrong

A fasting glucose only reads true after at least 8 hours without food or caloric drinks. Eating, a recent illness, steroid medicine, a hard workout the day before or a short night can push it up; a sample that sat for hours before it was spun can read lower, because the blood cells keep using the sugar.
