Alcoholism, liver cancer, hepatitis (liver infection), heart failure and blood disorders are diseases that can cause your liver to be enlarged, according to the Mayo Clinic. A large liver, also known as hepatomegaly, is tender and painful and must be checked immediately. Your doctor can be palpate (feel) your liver during a physical exam when it moves below your rib cage.
Position the patient face up on a comfortable surface. Make sure the legs are supported.
Stand on the right side of the patient and place your hands on the right upper part of the patient's stomach and feel for the rib cage.
Slide your fingers to the lowest part of the rib cage.
Slide your left hand underneath the patient's back for support.
With your right hand, hook your fingers underneath the last rib cage and apply firm pressure upwards. Do not let go.
Ask the patient to take a deep breathe and you should feel the liver's edge if it is enlarged.
