My little brother who is 15 turning 16 in november , and who is overweight (290 lbs), the doctor said with his height (5'11) he should be 210.
He tested his blood glucose once with my dad's glucose testing kit (Dad's a diabetic) after fasting for 8 hours and staying up all night until 7am, his glucose came out at 6.1 mmol on one finger and 6.4 mmol on another finger...Isn't that in the range of having pre-diabetes?
Anyway the thing that confuses me is, he tested himself again a month later, and after fasting for 12 hours (and actually sleeping through the night, and not staying up all night), his blood glucose was at 5.5 mmol which i read on the internet is normal.
So my question is, is he a prediabetic or not?
And I read the fasting should be between 8-12 hours, how can this be an accurate amount of time if the glucose level differs so much between the 8-12 hours....
He has recently went to the doctor and got a routine blood test, and the doctor said everything came back normal.
Also: He is currently working out regularely and has lost 10 pounds
