Her symptoms could be due to any number of things:
* intestinal parasites (worms)
* endocrine disease (Cushings, thyroid, Addisons, etc)
* liver, kidney or other organ failure/disease
* cancer
* etc......

Her symptoms sound serious and I think you need to have her examined by your veterinarian. Weeks of weight loss and diarrhea is not good. Even if the vet finds that it is just old age there are medications she can be given to help her walk better and be more comfortable.
