My 12 year old boy just got his yearly check up. He got an excellent report after a very thorough work up. He has HCM but it’s mild and hasn’t progressed in years. He’s got a clean bill of health but he’s lost weight slowly over the years . He’s still at a healthy size at 9 lbs but he looks skinny to me. The dry food I was giving him for years was making him puke. Thinking that was the cause of the weight loss, I give him only wet food now. Science Diet. He takes a low dose of benezepril and plavix. Any weight gain suggestions?
