Alanine aminotransferase (ALT) elevation often raises concerns. It is an important indicator of liver health and is usually detected during physical examinations. High ALT levels may suggest inflammation or damage to the liver, but there is no need to panic excessively as there are many reasons for this condition. Firstly, the most common cause is hepatitis, whether viral hepatitis (such as hepatitis B and C) or other types, which can all lead to increased ALT levels. This occurs because damaged hepatocytes release more ALT into the bloodstream. In addition, fatty liver disease is also a common cause, especially among obese individuals or those who consume alcohol for a prolonged period. The accumulation of fat in hepatocytes causes damage to them, leading to elevated ALT levels. The impact of medications cannot be overlooked. Some drugs have potential toxicity to the liver, such as certain antibiotics and cholesterol-lowering medications. Long-term use of these drugs may increase liver burden and cause ALT elevation. Therefore, regular monitoring of liver function during medication use is a good choice. Lifestyle also plays an important role. Excessive alcohol consumption, chronic sleep deprivation, and unhealthy eating habits all put pressure on the liver and increase ALT levels. The fast pace of modern life has led many people to neglect healthy lifestyles, causing their livers to become overloaded. Lastly, certain chronic diseases may also cause elevated ALT levels, such as diabetes and thyroid disorders. These diseases may indirectly lead to liver dysfunction by affecting metabolism or the immune system. Therefore, if elevated ALT levels are detected, it is recommended to seek medical attention promptly for detailed examinations to rule out potential health issues. Maintaining a healthy lifestyle and undergoing regular physical examinations are key to preserving liver health. Through balanced diets, moderate exercise, and good sleep habits, the risk of elevated ALT levels can be effectively reduced.
