Common Liver Diseases
The liver is one of the most important organs in the human body. It performs more than 500 essential functions, including filtering toxins, producing bile for digestion, storing nutrients, regulating blood sugar levels, and supporting the immune system. Because of its vital role, keeping your liver healthy is essential for overall well-being.
Unfortunately, liver diseases are becoming increasingly common due to unhealthy lifestyles, viral infections, obesity, excessive alcohol consumption, and certain medical conditions. Many liver diseases develop silently without obvious symptoms, making early detection and prevention extremely important.
In this article, we’ll discuss the 10 most common liver diseases, their causes, symptoms, treatment options, and practical prevention tips to help protect your liver.
