Every year on April 19th, the world observes World Liver Day to raise awareness about liver health and the silent threats posed by liver diseases. The liver is one of the most vital organs in the human body, yet it’s often taken for granted. By understanding liver function, recognizing risk factors, and adopting preventive care, we can take simple steps toward a healthier future.
Why Is Liver Health Important?
The liver performs over 500 essential functions, including aiding digestion, storing nutrients, detoxifying harmful substances, regulating metabolism, and supporting the immune system. Without a healthy liver, the body cannot function properly.
While the liver has a unique ability to regenerate, it can only withstand so much damage. Poor lifestyle choices, infections, or harmful habits can lead to liver diseases, which are often silent but can be life-threatening.
