I always sweat a lot when I wake up in the morning. This morning I took a shower and when I got out I was very hot, flushed, sweaty, and weak. My hands were cold . The morning sweats have been present for years. I had my wife take my blood sugar , it was 140 (I had had black coffee, but nothing to eat). I am 56, 6 ft tall and weigh 265. Any thoughts about what could be going on with me?
