Liver health and Alanine aminotransferase levels

The topic provides useful context on the rising burden of non-communicable liver diseases and public health challenges, which can be used to support answers on health sector issues, though it lacks the specificity of a government policy or report.

Notes

  • Liver diseases cause approximately two million deaths globally per year according to the WHO.
  • Viral hepatitis resulted in 1.3 million deaths in 2022, with 254 million chronic hepatitis B and 50 million chronic hepatitis C cases.
  • Metabolic dysfunction-associated steatotic liver disease (MASLD) is a rising burden linked to obesity and diabetes.
  • Alanine aminotransferase (ALT), or serum glutamic-pyruvic transaminase (SGPT), is an enzyme primarily found in liver cells.
  • ALT leaks into the bloodstream when liver cells are damaged or inflamed, serving as an early marker of injury.
  • ALT is also present in smaller amounts in muscles and the heart, meaning elevated levels do not exclusively indicate liver disease.
  • Normal ALT levels do not exclude significant liver disease, as levels can remain normal in MASLD or return to normal in advanced cirrhosis due to cell loss.
  • Risk factors for liver injury include obesity, diabetes, thyroid disorders, high cholesterol, viral hepatitis, long-term medication, alcohol consumption, and sedentary lifestyles.
  • Management of metabolic liver disease centers on lifestyle modifications: weight maintenance, reduced alcohol intake, dietary changes, and increased physical activity.
