Since I was young, I've had sensitive blood sugar. About once a month I'll suddenly become very hungry, with horrible headaches and dizziness, and have to stop everything and eat and drink slowly until I can sit up again. This is just my norm. I can't skip a meal without getting very sick. (Throwing up, shakiness, fatigue) Do you show symptoms of type 1 diabetes suddenly or gradually? I've had some minor health problems for a few months, and I feel like something is wrong.
