I keep having what i believe are hypo's. I feel very shaky and weak, sweating palms, heart rate speeds up, confused, and like i am going to collapse. Usually if i have a sugary drink or a chocolate bar i start to feel a little bit better after 10 minutes or so. But recently this is not working so well. I have had 2 blood tests in the past that have shown i am not diabetic and am currently awaiting the results of a 3rd blood test. I am morbidly obese. Is it possible to still be diabetic even if fasting blood tests are saying i am not? Are there other tests that can be done? Please help.
