Raised liver function refers to elevated levels of certain enzymes in the blood, indicating potential liver damage or inflammation. These enzymes, such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST), are released into the bloodstream when liver cells are injured.
Liver function tests (LFTs) measure the levels of various enzymes and proteins produced by the liver. Elevated levels of ALT and AST suggest liver cell damage, while high levels of alkaline phosphatase (ALP) and gamma-glutamyl transferase (GGT) may indicate bile duct obstruction or liver disease.
The most common causes of raised liver function include:
Many people believe that only heavy alcohol use or severe infections can raise liver function. However, even mild liver damage from over-the-counter medications or minor viral infections can cause elevated enzyme levels., some people assume that raised liver function always indicates a serious condition, but it can also result from temporary factors like intense exercise or certain foods.
If liver function tests show consistently elevated levels, it is important to consult a healthcare provider. Early detection and treatment of underlying conditions can prevent further liver damage. Lifestyle changes, such as reducing alcohol intake, maintaining a healthy weight, and avoiding harmful substances, can also improve liver health.
