World Liver Day is observed worldwide every April 19, having been established in 2010 by the European Association for the Study of the Liver (EASL). The day aims to highlight the importance of liver health and educate the public about preventive measures to maintain it. The liver performs up to 500 essential functions, and when it malfunctions, it can lead to various diseases, including hepatitis, fatty liver disease, cirrhosis, and liver cancer. EASL collaborates with organizations such as the American Association for the Study of Liver Diseases and the Asian Pacific Association for the Study of the Liver to address the growing burden of liver disease. Preventive measures emphasized on this day include reducing alcohol consumption, quitting smoking, and maintaining a healthy diet.
