Sorry to hear you're going hypo - no fun at all. I think it could be down to the gh - growth hormone (somatropin) - . I used to get the same problem taking even 4iu / day. It seems counterintuitive to think that GH could cause hypoglycemia, since it's secreted in response to low blood sugar levels. But if you're healthy and you take high doses (i.e. non-clinical doses) or GH (or IGF-1), you'll often get a period of hypoglycemia, followed by hyperglycemia. The main reason for this is that GH causes an impairment of glucose tolerance and insulin sensitivity, so your cells don't respond to insulin. Insulin resistance itself causes feelings of hypoglycemia. But this isn't actually diabetes. However, the longer it goes on, the more insulin is released from the pancreas to counter the downgrading of the receptors which normally respond to insulin on the cells. So, you definitely have to get on top of it a.s.a.p.
If you start to experience excessive urination, thirst, and appetite, you should take action. I had to come off GH, and switch to low grain, no sugar foods; increase cardio. Also, I steered clear of orals, because when you come off these, you often have increased cortisol levels, and this in itself causes glucose intolerance. Obviously, depending on your weight, this alone could be the cause of you going hypo, because the heavier you are, the greater your chances of developing glucose intolerance.
Hope it all works out!
