How do you get your husband to get help for him self?

He might have diabetes as well - get him checked out, or buy a blood sugar check device from your pharmacy and do it yourself, it's easy enough - just a prick on the end of a finger, squeeze a droplet of blood onto a test strip, place in the machine and get a reading. If it's in double figures he needs to get treatment and change his eating habits - cut out anything with sugar in it for a start. Left untreated he could be on the way to amputation.
