Atherosclerosis In Pet Birds: The Silent Killer

Atherosclerosis is a condition marked by the buildup of fatty deposits in the arteries, which reduces blood flow. It is a debilitating condition that is common in older birds and is often associated with sudden clinical deterioration. Birds, particularly companion psittacine species, seem to be more vulnerable to atherosclerosis than any other mammals aside from humans. The most frequent sign of this condition is sudden death, but other clinical symptoms may include difficulty in breathing, lethargy, neurological issues, weakness and death. Accumulations of lipids, cholesterol, inflammatory cells, and cellular debris inside the arterial media and intima are the components of atherosclerotic lesions. Treatment should focus on identifying and addressing underlying causes and contributing factors, as well as managing complications like systemic hypertension or congestive heart failure. A comprehensive treatment approach that consists of both medical and non-medical strategies is recommended.
