K70-K77: Diseases of liver

The "Diseases of the liver" group includes various conditions related to the liver, a vital organ involved in many critical body functions. Common causes of liver disease involve factors such as excessive alcohol consumption, viral infections like hepatitis, and metabolic syndromes such as obesity and diabetes. These conditions can affect the liver by causing inflammation, fibrosis (scarring), and ultimately lead to liver failure or cancer. Symptoms often associated with liver diseases include yellowing of the skin and eyes (jaundice), pain and swelling in the abdomen, chronic fatigue, nausea, and loss of appetite. Some liver conditions progress gradually, becoming more severe over time, while others can have a rapid onset. All these diseases primarily affect the digestive system but can have systemic effects due to the liver's role in nutrient metabolism, detoxification, and storage of vital substances.
