My son was diagnosed with celiac disease 2 years ago at age 15. He was 5' tall and 70 Ibs. His symptoms disappeared as soon as he went on a gluten free diet. He grew 3" and gained 20 Ibs in just 5 months. He is almost 17 now and is 5'8" tall, but he is still 90 Ibs. Also, his joint pains are back. He has been complaining of joint pain all over his body for the past couple of weeks. He has been on a gluten free diet, and I know he hasn't been cheating since he is very concerned about his weight and height. We have made an appointment with a GI again. Has anyone been having problems with joint pain and weight after going on a gluten free diet?
