I used to have hypoglycemia, but overcame it with fasting. At least I am pretty sure that that is what did it. I don't think I just "grew out of it" so to speak.
You could talk to a doctor that understands the benefits of fasting and ask them what they think.
I don't know if my way is really the way. I didn't do anything special. Just a lot of little fasts leading up to bigger ones.
