My friend is a 63 year old male, is not physically active, he s 5 6 and weighs 190. He works from home, and sleeps all the time. He falls asleep at his desk, he will sleep at night until four in the morning, gets up to go the bathroom a lot, and is only up a few hours when he s asleep again. He won t go to the doctor but I am very scared for him. His memory is not as good as it use to be as he is making many mistakes like leaving the groceries in the car when he comes home after going to pick up some things from the store. Could this be diabetes?
