What could signal liver problems in a horse?

Yellow gums can indicate liver problems in a horse, as they are a sign of jaundice, which occurs when there is a buildup of bilirubin in the bloodstream due to liver dysfunction. When the liver is not functioning properly, it struggles to process and eliminate bilirubin, leading to a yellowish discoloration of mucous membranes, including the gums. This symptom is a direct reflection of liver health and is often used by veterinarians as a key indicator when assessing a horse’s liver function.

The other symptoms, while they may suggest health issues, are not as specific to liver problems. A dry coat might indicate inadequate grooming, dehydration, or nutritional deficiencies rather than a direct link to liver function. Foul breath, while it can be symptomatic of various health issues, is not specific to liver problems and may also relate to dental issues or gastrointestinal problems. Low energy levels can indicate a range of health concerns from anemia to chronic disease and are not uniquely indicative of liver dysfunction. Thus, yellow gums serve as a more precise and significant signal of potential liver issues in horses.
