Hi Matt. I just wanted to respond so that you wouldn't feel as though nobody was listening! I can't offer you much help with your questions. I have a 9 year old daughter with salt losing CAH but she's never had a weight problem. I hope you don't get discouraged by the lack of response so far. Some times it takes awhile to get an answer... but one always comes. I'm sure you're a welcome addition to this board as there are many moms here with CAH sons. I'm sure they'd love the opportunity to ask questions of a male adult who's experienced some of the issues their sons will be facing. Good luck. Hope to see your name popping up here more often.
