A mild case of thumps often goes away on its own after rest, rehydration, and replenishment of electrolytes. More severe cases – or situations where the horse is exhausted and dehydrated – need immediate veterinary intervention. With substantial fluid and electrolyte loss, a veterinarian may need to quickly administer a balanced electrolyte solution through a stomach tube or even intravenous (IV) catheter. Blood work may be needed to measure hydration status as well as electrolyte and pH balance and determine the underlying cause of thumps.
