Exhausted horse syndrome

Sa？etak Exhausted horse syndrome is a multi- systemic disorder in sport horses subjected to long term physical activity, especially during hot weather conditions. Increased physical activity can lead to dehydration, hypovolemia, electrolyte loss, acid-base imbalance, depletion of energy reserves and hyperthermia. The clinical presentation depends on the severity and speed of onset of fatigue, and on the individual tolerance of the horse to exercise intensity. Diagnosis is based on the anamnesis, clinical signs and laboratory findings. In severe cases, the diagnosis is easily established, whilst early recognition in mild cases is difficult due to the subtlety of clinical signs and lack of objective clinical and diagnostic criteria. The treatment goal is comprised of three main approaches: decreasing body temperature, replacing fluids and electrolytes, and restoring circulating blood volume. Prognosis is good in mild cases, while in severe cases, presentation is questionable due to possible complications, with the possibility of a lethal outcome. Prevention of exhausted horse syndrome is possible by choosing the appropriate horse breed for the sport, maintaining horse health through regular veterinary inspection, gradually increasing training intensity, and avoiding demanding conditioning training lasting several days in a row. The rider’s evaluation of horse health through the competition is of great importance
