There are no drugs out to help Celiacs with digestion or weight gain. The
only thing that helps a celiac to improve is to MAINTAIN A STRICT
GLUTEN-FREE DIET. If you are still losing weight, you must be ingesting
gluten SOMEWHERE. I would advise you to go over your diet; perhaps you are
ingesting something that you do not realize has gluten in it. That could
be dangerous!!
