Blood Disorder in Horses

ADVERTISEMENT

Hyperlipemia

 

Hyperlipemia is a blood disorder that occurs in overweight horses, as well as some donkeys. Horses with this condition have an abnormally high amount of fat in their blood. And although it only affects a small percentage of the world's equine population, Hyperlipemia is a very serious disorder that has a high rate of mortality among those affected. For this reason, it is important to know the symptoms of this condition, so that you may seek immediate veterinary care for your horse if it is suspected of having Hyperlipemia.

 

Symptoms

 

  • Lethargy
  • Slowness
  • Loss of appetite
  • Liver failure
  • Severe weight loss, which occurs in a short period of time
  • Abnormal behavior
  • Nervousness (i.e., head pressing, circling, wandering, unaware of familiar surroundings)

 

Causes

 

Horses that are extremely overweight are those most at risk for hyperlipemia, especially those that undergo a quick change in diet or is starved. As a coping mechanism, the horse’s body uses its fat reserves to feed itself. The resulting increase in blood's fat levels cause the liver to work excessively and begin the process of liver failure.

 

In addition, other types of stress may make the horse more prone to the condition. Horses that have a high resistance to insulin, for some reason or another, are also at risk for hyperlipemia.

 

Diagnosis

 

Hyperlipemia is a very rare condition, but it is not difficult to diagnose. Upon seeing a veterinarian, he or she may order a medical history on the horse and take a blood sample. A positive diagnosis of hyperlipemia will show excessive levels of fat in the blood's plasma.
