Whenever I eat, without fail, within one hour, my face looks VERY gaunt and skull like. Shrink wrapped. My eyes sink way in as well as my cheeks. I look like I'm ready to die, but I feel fine. Within five or so more hours I start to return to normal. Why is this? It's usually worse with sugary items.

Are you diabetic? Are you drinking fluids?

I don't know if I am diabetic. Could that be the cause? It runs in my family. What are the symptoms?
