Yes that is a reliable source for info.
Not sure I've ever heard of cloudy eye issue being related to / cleared up from a de-wormer, so not sure on that aspect but I suppose there always is the possibility of our pets having worms.
Regardless of whether the weight loss, blood test results & other symptoms are from worms or IBD or something else it would be a good idea if you could discuss the whole scenario with your vet to get his/her recommendations on where to go from here.
