My dad is constantly feeling hot from waist up, is this normal?

My 69-year old dad is constantly feeling hot from waist up. In the morning, his body temperature is normal then it gradually rises. He cannot sleep well at night because of that body heat. He said he feels like he's having a fever but he doesn't. His doctor said that it may be menopause because during this stage you will experience hot flashes. But what he's experiencing is different, he said. So is this a symptom for menopause or a different thing? Is it normal?

I've never heard of menopause in a guy.  I know sometimes they can have abnormally high estrogen levels, giving something called gynecomastia.  I definitely would seek a second opinion for your dad on this one from perhaps an internal medicine physician.  If he also is getting red on his trunk, have you ever heard of mast cell activation disorder?  There is a test for it that should be done in conjunction with having the symptoms.
