I have had type 1 diabetes for about 6 1/2 years. I fall into a rare group that is late onset type 1. They used to call Type 1 juvenile diabetes, as the average age on onset is something like 12 years old.

I take insulin daily and monitor my blood sugar through a continuous glucose monitor similar to what you described. If your neighbors son has nerve and blood vessel damage from unmanaged high blood sugars, it is not reversible. This is how diabetics go blind and lose their feet, among other lovely outcomes. Sounds like he has a pretty bleak future ahead of him.
