When I was younger I was not that heavy. I was in the Navy so I had to stay in my weight limits. I developed Chrones Desease and with that one of the medications for Chrones is Predisone which is a steriod. Each time I had a flare up (when your intestense get inflamed) I had to be on Predisone. Well over the year that made me gain to 300 pounds. You might ask, "isn't there any other medication they could of given you?" and the answer would be, I've tried but I am allergic to most all of them. Anyway, a few years back I developed a heart infection which is another story and had to get a heart valve replaced. So not I have chrones and a heart valve replacement and you can see how 300 pounds for this 5"7" male could be. I got down to 240 pounds pre-op which I think is good now can't wait for my first fill to stop the hunger. By the way, I am also allegic to the anti-biotic they gave me during surgery and develop a rash all over my body and guess what they gave me, you guessed it Predisone.
