Not to discount disease, as that should always be ruled out first, but I've noticed my geckos fluctuate in weight over time. Most of them dropped 7-10 grams over the winter, have gained some of it back, but not all. All are active, healthy & eating. I think it can be quite normal for them to fluctuate a bit, especially upon stressors, like a trip in the mail & a new home. But, certainly get a fecal done.
