Can Heaves Kill A Horse?

Can heaves kill a horse? This is a question that many horse owners may ask themselves when their beloved equine companion is diagnosed with this respiratory condition. Heaves, also known as recurrent airway obstruction, is a chronic respiratory disease that can severely impact a horse’s quality of life. While it may not directly cause death, untreated or poorly managed heaves can lead to complications and secondary issues that can be life-threatening for the horse.

Heaves is characterized by inflammation and constriction of the airways, leading to difficulty breathing, coughing, wheezing, and increased respiratory effort. If left uncontrolled, heaves can result in decreased lung function and compromised oxygen exchange, which can put immense strain on a horse’s cardiovascular system. As the disease progresses, horses may experience weight loss, decreased energy, and overall decline in health.

One of the significant risks associated with severe cases of heaves is the development of respiratory infections, such as pneumonia. The compromised respiratory system makes horses more susceptible to bacterial and viral infections, which can be life-threatening if not promptly diagnosed and treated.

Another potential complication of heaves is the development of pleuropneumonia, an infection that affects the lungs and the lining of the chest cavity. The accumulation of pus and fluids in the chest can cause severe respiratory distress and, in some cases, can be fatal if not addressed promptly with appropriate veterinary care.
