The left lobe of the liver is part of the liver and has functions common to the liver, as the liver is the equivalent of the body’s chemical factory, where much of the metabolism of food or the body’s metabolism takes place. The liver also secretes coagulation substances, which regulate the body’s coagulation index. It is also involved in the synthesis of proteins. In addition, in patients with liver disease, as the metabolic function of the liver is affected, the patient may show an increase in transaminases or bilirubin, as well as pain in the liver area, which may be accompanied by infection in severe cases. In severe cases, this may be accompanied by infections. In the case of multiple diseases, the liver function may be reduced and eventually liver failure may occur. The left lobe of the liver is also a part of the liver, and some lesions, including tumors or stones, can affect the function of the left lobe of the liver and increase enzymes or bilirubin secondary to the disease.
