My son is 17 and has lost almost 60 pounds and now has difficulty when he eats. He can take 1 or 2 bites then has to stop because he get nausea....He also has really bad anxiety. We are working with his doctor on this issue. Could they be related?? I think his rapid weight loss has to do with this eating thing. This has only been happening for about a year now...it takes him a long time to eat. Any suggestions?
