Can you have hypoglycemia without having diabetes , i have all the symptoms which then get better when i eat?

Yes, but uncommon: The symptoms of hypoglycemia are the same as many other things. There are hypoglycemic conditions, but they are actually uncommon, although there are people who will try to convince you otherwise. Talk to your doctor. You can also buy (fairly cheap) a glucometer at your local pharmacy and check your blood glu when you think it is low. Make sure you calibrate and follow instructions.
