What Causes High ALT Levels in Pets and How to Manage It?


Dear VetBabble: What Causes Elevated ALT in Pets and How Can I Address It?

One of our concerned pet owners asked about the causes of elevated ALT (Alanine Aminotransferase) in their dog, who had been discharged from the hospital after an almost week-long stay. The dog’s ALT levels went from 2200 to around 500, and the vets could not find the cause after extensive testing. Liver cancer, tick diseases, and heart-related issues were ruled out. The pet owner seeks to know more about elevated ALT and possible causes for the condition, as this can be a significant concern for pet owners dealing with liver indicators in their dogs or cats.

Understanding Elevated ALT and Its Significance

ALT is one of the most important liver indicators in dogs and cats. It can also be elevated when there is significant damage to the muscle. In general, ALT is considered a fairly sensitive marker for some type of liver damage. There are several other markers for liver disease, so only knowing about the elevations in ALT may be misleading. If ALT is the only marker elevated, this usually indicates an inflammatory or infectious disease causing harm to the hepatic system.

Finding the Root Cause of Elevated ALT Levels

Identifying the cause of elevated ALT levels in pets can be a complex process that involves various tests and examinations. Since many different factors can contribute to elevated ALT, pinpointing a specific cause can sometimes be challenging for veterinarians.

Some possible causes of elevated ALT levels in pets include infections, toxins, medications, inflammation, trauma, and congenital defects. To gain more insight into your pet’s ALT levels and overall health, we recommend discussing all laboratory testing and diagnostic imaging with your veterinarian. You can also refer to our article on Guide to Kidney Disease in Dogs for additional information on related health issues in pets.

Maintaining Your Pet’s Liver Health

To ensure your pet’s liver remains healthy, regular check-ups and bloodwork are essential. Bloodwork helps identify any potential issues and allows for early intervention, potentially preventing severe health complications. Our article Why is Bloodwork for Dogs and Cats Important? provides valuable insights into the significance of bloodwork in maintaining your pet’s overall well-being.

In addition to routine bloodwork, it’s crucial to keep an eye on your pet’s behavior, appetite, and energy levels, as these can be indicators of potential health concerns. If you notice any changes in your pet’s demeanor or if they’re displaying symptoms such as vomiting, diarrhea, jaundice, or increased thirst, it’s important to consult your veterinarian immediately.

By staying informed about your pet’s health and maintaining open communication with your veterinarian, you can help ensure your beloved companion remains healthy and happy for years to come. Remember, we are here to provide support and answer any questions you may have about your pet’s wellbeing.
