Proventricular Dilatation Disease - PDD

By

Definition: Proventricular Dilatation Disease, or PDD, is a disease that can affect any parrot or hookbill.

The symptoms of PDD include a change in droppings, weight loss, vomiting, and a swollen, hard crop.

It is still not known how PDD is transmitted, and as of now there is no treatment or cure. PDD is known to be a fatal disease, although some birds are able to live with PDD for many months or even years. If you suspect that your bird may have PDD, you should consult an avian veterinarian as soon as possible.
Also Known As: Macaw Wasting Syndrome, Parrot Wasting Syndrome
Examples:
Judy's Eclectus was diagnosed with PDD when she noticed that he had begun to lose weight.
