Frankly speaking, Celiac’s disease is not diagnosable except when you basically stop eating gluten and your body responds to that.  It’s not highly scientific, but it works.  This being said, Celiac’s disease interestingly enough causes both weight gain and weight loss.  It causes weight loss, because you are always throwing up, you are always having greater problems in general, and it’s just not fun.  But at the same time Celiac’s disease actually causes quite a bit of swelling and water retention in the body, which naturally results in weight gain.  So after just a week of following a gluten free diet, many will find that they have actually lost weight, because the swelling alone goes down.  I know, it sounds too good to be true.  But if you have Celiac’s disease, it is that simple in some cases.  It takes that week so often because your body still has to flush out all the gluten you have previously ingested.  This being said, it doesn’t actually require any medication.  Now if I had Celiac’s disease, I would just be in trouble, because I’m too undisciplined to figure out all the little idiosyncracies of it.  But that’s why so many who have it are amazing.  Well granted you would be forced to be more disciplined, because the results of not being disciplined are a big deal to say the least.  But this being said, Celiac’s disease is a big deal.
