Definition & Meaning of "heaves"

What is "heaves"?

Heaves, also known as recurrent airway obstruction (RAO), is a common respiratory condition that affects horses, particularly those kept in stables with poor ventilation or exposed to dusty environments. It is characterized by difficulty in breathing and coughing, especially during exercise or when exposed to allergens like dust or mold. Heaves is often caused by permanent inflammation of the airways, leading to the narrowing of the small air passages in the lungs. Treatment usually involves minimizing exposure to irritants, providing good ventilation, and managing symptoms with medications. Proper stable management and environmental control are essential for managing heaves and improving the horse's quality of life.
