R16.0: Hepatomegaly, not elsewhere classified

Your liver is enlarged.

The liver is an important organ on the top right of the abdomen. Nutrients from food are processed in the liver. Fats and sugars are formed and stored in the liver. The liver is thus involved in the metabolism. The liver also produces many proteins for the body. The proteins are important for blood clotting, for example. Other proteins convey substances through the body or keep fluid in the blood vessels. The liver also helps to detoxify the body. The liver produces bile fluid so that toxic substances can be excreted. Bile fluid is also important for digesting fats.
