Re: 14 year old. Help as dr. doesn't seem concerned
Maglib: I'll try to answer some of the diabetes issues. First, he's 14 and in puberty. Insulin is a hormone also. Do you know what ketones are? They're the body using fat for fuel instead of carbs. They can be dangerous to a diabetic and if they're high they need to be flushed out by drink a lot of water or getting insulin to get rid of them. You don't want kidney damage. Ketones can be fatal if you end up in diabetic ketoacidosis. His 106 BG seems fine. His sugars might be higher being a teen. You never know what they eat and how long it takes to metabolize.
The exercise is good to keep the sugars down. Exercise is a natural insulin.
I wouldn't be concerned about diabetes for him. If he was in the 150-500 range then yes. At this age I'd be more concerned for T1 diabetes since it's becoming an epidemic. You can get T1 up into your 30's. It's an autoimmune disorder, just like celiac and lupus. I'm sure you know the signs of highs and lows. If you see him peeing and drinking a lot then check his sugar for highs. If he's high, get him to the hospital.
