How to Manage Exertional Rhabdomyolysis (Monday Morning Disease) in Horses.

Exertional Rhabdomyolysis, commonly known as "Monday Morning Disease" in horses, is a condition characterized by the breakdown of muscle tissue due to overexertion. This often occurs in horses undergoing strenuous exercise after a period of inactivity, such as over the weekend, hence the name. I can also be attributed to a situation where the plane nutrition of nutrition of the horse is way above the work or exercise that the horse engages in. The pathogenesis of this condition involves the rapid breakdown of muscle fibers, releasing myoglobin into the bloodstream, which can lead to kidney damage if not promptly treated.

Clinical signs of exertional rhabdomyolysis in horses may include stiffness, reluctance to move, muscle pain or swelling, and dark urine due to the presence of myoglobin. It is important for horse owners and trainers to be aware of these signs and seek veterinary assistance immediately if they suspect their horse is suffering from this condition.

Prevention of exertional rhabdomyolysis in horses involves proper conditioning and training protocols, including gradual increases in intensity and duration of exercise to avoid sudden strain on the muscles. Adequate warm-up and cool-down periods, regular turnout, and a balanced diet rich in electrolytes and antioxidants can also help support muscle health and prevent episodes of rhabdomyolysis.

Treatment for exertional rhabdomyolysis in horses may include rest, anti-inflammatory medications, and intravenous fluids to support kidney function and flush out myoglobin from the bloodstream. In more severe cases, hospitalization and intensive care may be required to monitor and manage complications such as acute kidney injury.

In conclusion, exertional rhabdomyolysis can be a serious and potentially life-threatening condition in horses, but with proper management and preventive measures, it can be effectively controlled. Horse owners and trainers should be vigilant in monitoring their horses for signs of muscle injury and take proactive steps to prevent and address exertional rhabdomyolysis to ensure the health and well-being of their equine companions.
