A common problem among horses is chronic inflammatory disease that can cause weight loss. These horses are the ones that continue to eat normally and are on a good quality ration but still lose weight. Chronic inflammatory disease can affect any body system and cause weight loss. One of the most common causes of chronic inflammatory disease is intestinal parasites and although you may be deworming your horse routinely, your horse can develop a larval intestinal infection that does not respond to regular dewormers. Some of these horses require a special deworming program to kill these larval parasites.
Horses with chronic lameness will lose weight. This is common in older horses with arthritis, but I also see this in many horses that may be slightly lame from a previous case of founder. Actually, any horse that is experiencing chronic pain will also lose weight. Disease of many different organ systems can cause weight loss. Heart failure, especially if related to infection of the heart valves, can cause weight loss and a cardiac ultrasound exam is required for diagnosis of this condition. Some horses also have chronic inflammation in their lungs called heaves that leads to difficulty breathing and these horses also commonly lose weight. In older horses with weight loss, neoplastic disease or cancer is a major concern. Cancer that affects the liver, intestinal tract, or lungs are the most common areas involved in horses. If you have a horse that is losing weight but is otherwise normal, contact your equine veterinarian.
