He eats A LOT, but he doesn't gain any weight...His weight just stays the same. He told me that he doesn't get full, that he can keep eating and won't really know when to stop. He isn't overweight at all. He is 6 foot 1 and he weighs 185 pounds.
He seems overly tired. Last night he slept for 11 hours...
He also seems thirstier than most people. He drinks about 10 bottles of water a day...

Is it possible that he has type 2 diabetes??He said he doesn't want to go to the doctor because theres nothing wrong with him...
