Do you often feel tired and lethargic? Do you perhaps also have pain in your upper right abdomen, and does your skin or eyes appear somewhat yellowish? Then your liver could be the culprit. Its the largest internal organ in your body and performs vital functions: The liver detoxifies you and breaks down foreign substances and toxins. It produces proteins and regulates metabolism. It produces bile to digest fats. It activates and breaks down hormones. There are important liver enzyme levels, an increase of which can serve as an indicator of liver damage. These include: GPT (glutamate pyruvate transaminase, also known as alanine aminotransferase, ALT), which indicates the amount of this enzyme produced in the liver. GGT (gamma-glutamyltransferase), an enzyme involved in amino acid metabolism, which is predominantly found in the liver and can provide clues about liver disease. A liver function test can help detect liver problems early and take appropriate action, which is why testing is beneficial for everyone. Nevertheless, there are groups of people for whom testing is particularly recommended, including: people with existing liver disease, alcohol consumers, overweight individuals, people taking certain medications, diabetics, and people with a family history of liver disease.
