Atherosklerose bei Vögeln
Also known as: Arterienverkalkung
Die Atherosklerose ist eine degenerative Gefäßerkrankung, die bei älteren Ziervögeln häufig auftritt und bei der Fettablagerungen die großen Blutgefäße verengen und versteifen. Sie steht im Zusammenhang mit fettreicher Samenernährung, Übergewicht und Bewegungsmangel. Die Erkrankung kann plötzlichen Tod, Schwäche, Kollaps oder neurologische Symptome verursachen und wird häufig erst bei der Obduktion entdeckt.

Overview
Atherosclerosis is a common cardiovascular disease of older psittacines, in which fat and other material accumulate in the walls of major arteries, narrowing and hardening them. Parrots such as African greys and Amazons are frequently affected.
Causes
High-fat, seed-based diets, obesity, inactivity, and chronic reproductive hormone exposure contribute to the buildup. Age increases risk.
Signs
Many birds show no signs until sudden death. Others have weakness, fainting, exercise intolerance, labored breathing, or neurological signs such as limb weakness.
Diagnosis
Diagnosis is challenging in life; imaging, blood lipid measurement, and assessment of risk factors help, while definitive diagnosis is often at necropsy.
Treatment & Management
Management focuses on weight loss, a lower-fat balanced diet, exercise, and sometimes medications that affect blood lipids or support the heart.
Prevention
Feed a balanced low-fat diet rather than seeds, encourage activity, maintain healthy body weight, and limit chronic hormonal stimulation.
