Hepatic Lipidosis and Atherosclerosis

What is it?
Fatty liver disease (hepatic lipidosis) and atherosclerosis (hardening of the arteries) are common in parrots fed high-fat seed diets with little exercise. Amazons, cockatiels, and African greys are at higher risk.
What signs should I watch for?
Signs to watch for include obesity; overgrown beak or nails; lethargy, breathing difficulty; and weakness or sudden collapse.
How is it diagnosed and treated?
Diagnosis uses blood work, X-rays, and other imaging. Treatment focuses on gradual diet change, weight loss, liver support, and more activity.
Can it be prevented, and what's the outlook?
Prevention is a formulated diet with vegetables, limited seeds and nuts, and daily exercise.
