Many avian diseases affect not only the bird’s whole body, but also cause heart and blood vessel disorders in birds of any age, including young birds. These bird disorders are usually due to infections or old age. Just like humans in old age, some birds commonly suffer from heart and blood vessel disorders.
If the heart and blood vessel disorders are due to old age, symptoms may include, difficulty walking and flying (or other movements), difficulty breathing, and a shortness of breath.
If the heart and blood vessel disorders are due to an infection, symptoms usually include, general lethargy, diarrhea and appetite loss.
Some infections that can cause heart and blood vessel disorders are polyomavirus and Pacheco’s disease, both of which are rapid and result in early death of the bird. And while some of the viruses can be deadly, protozoan parasites do not always cause a disease in the affected bird, unless triggered by stress or other illnesses.
Heart and blood vessel disorders caused by viral, bacterial or parasitic infections are generally diagnosed through blood tests.
