Hey, A few months ago I went on a extremley limiting diet... During this time I experienced severe dehydration, dry mouth, nausea, and lightheadedness. Once I started to go back on a more normal diet, the symptoms resided. However, during the past few days I ve started to experience more of the dehyrdation. To make matters worse, I have not slept in the past two days because of schoolwork.... Now I feel extreme dehydration, nausea, and lightheadedness again... My question is... Do I have diabetes, or are my poor habits causing diabetes-like symptoms? If I continue this pattern, could I develop diabetes, and, if I make better choices can I reverse the diabetes? Thank you!
