I have been working out hardcore for the last 8 mths and recently stopped working out due to the fact that i am now underweight (5'5 105lbs)and I dont want to lose anymore (am trying to gain some at the moment) I have sucessfully lost 25 lbs but I really only needed to lose 10-15. I have been having these weird feelings sort of like low blood sugar i guess, like if i dont have something sweet i will feel a little angry then when i eat something sugary i feel better, or sometimes when i eat carb rich foods like potatoes or rice i will feel super energized almost like a drunken feeling afterward and it like i just ate but i am still hungry. My grandfather has type 1 diabetes , so i am worried, plus i read being underweight can cause type 1 diabetes. should i test my own blood sugar and if so when should i do it. I dont like this feeling i get and i just want it to go away, should i stay away from carbs completely? I have also tried the low carb thing when i was dieting but i just seemed to be to tired to do anything, i hope this is not diabetes, please help!!!!
