Elevated alanine aminotransferase (ALT) levels are usually caused by chronic hepatitis B infection. However, high ALT levels are not necessarily due to disease; they may also result from physiological factors, such as irregular lifestyle habits or prolonged alcohol consumption. Patients need further examinations to determine the exact underlying cause.
