Many pets will have elevated liver enzymes at some point in their lives and may not show any outward symptoms. Often the only way elevated liver enzymes are diagnosed is during a routine laboratory test and/or physical exam. The liver is the main filtering system for the body and performs many functions. For example, the liver is involved in the metabolism of fats, protein and carbohydrates, production of bile which aids in digestion, synthesis of glycogen (related to blood sugar regulation), protein synthesis and of course filtering toxins. If your pet is diagnosed with elevated liver enzymes, there is a lot you can do to be proactive and help improve your pet's liver function.
