What are the causes of elevated alanine aminotransferase (ALT)?

There are several reasons for elevated alanine aminotransferase (ALT) levels, which can be summarized as follows: 1. Unhealthy lifestyle habits: Long-term alcohol consumption, staying up late, smoking, and other unhealthy habits may damage liver function, leading to elevated ALT levels. 2. Disease-related factors: - Liver diseases, such as viral hepatitis and cirrhosis, can damage liver cells and result in increased ALT levels. - Biliary tract diseases, such as cholecystitis and gallstones, may also cause elevated ALT levels. - Heart conditions, such as acute myocardial infarction, can lead to increased ALT due to damage to heart muscle cells. - Other factors, including certain medications, pregnancy, and kidney diseases, may also contribute to elevated ALT levels.
