Hypoglycemia isn't diabetes, but I guess since it deals with blood glucose, it explains why your'e asking here.

I'd suggest going to a forum like the american diabetes association (www.Diabetes.Org) or diabetes life (dlife.Com -- see support), as your question has been posed on those sites many times.

A quick answer: hypoglycemia is caused by too much insulin ,or insulinoma.
He needs to have his insulin levels tested by an endocrinologist; specifically, the pro-insulin.

Low blood glucose (hypoglycemia) is not a normal thing. If he has it frequently, it means he must continue to eat, which will cause weight gain. Using a fast-acting glucose (such as smarties candies) -- something that has dextrose listed as the first ingrediant -- will help to raise blood glucose fast.

You made no mention as to if your bf has type 1 diabetes and is on insulin. If he is on insulin, I strongly urge you to go to a dlife forum to discuss this with a larger audience, who is very experienced in hypoglycemic issues :).

Again, this is not a "very normal" thing.

Hey,

i would also check out health site guide, Healthsiteguide.Com. Its this healthcare web portal I have been using, and so far, it's been really helpful for getting information. There is a link on the homepage that says "healthcare information fast" and if you click it, it takes you to a page with medical encyclopedias. Or, if you want to go straight to info on diabetes, go to the "health concerns" drop-down menu on the left of the frontpage. If you click on diabetes, it will take you to a page of health websites, all of which have been pre-searched for diabetes. So if you click on any of the sites, you will go straight to their diabetes page. Give it a try and tell me if its helpful. Best of luck.
