I've been feeling very shaky/weak/lightheaded every time I'm hungry. It's becoming more of a problem lately, and more or less resolved when I eat something with carbs (might be improved with a sugary snack but I find my body respond better to carbs than just sugar). Could this mean that I'm diabetic/prediabetic? I have no known history of diabetes on either side of my family nor am I overweight (165cm/ 50.5kgs). However, I do crave sweets often and have always consumed sugary foods as a child.
