Chapter IV. Symptoms and signs in liver diseases

History

Acute liver disease may present dramatically with acute anorexia, nausea and vomiting. There may be intolerance to the sight and smell of food, to alcohol and to cigarette smoke. An intense itch may develop in the skin and this may precede the development ofjaun-dice, which may be noticed by the family before the patient. As jaundice appears, other symptoms may disappear. The patient may now notice dark urine and pale stools. There may now be right-sided abdominal discomfort caused by an enlarged or inflamed liver, or by an obstructed biliary tree. However, many patients have asymptomatic liver disease which is found incidentally as hepatosplenomegaly on routine examination, abnormal liver biochemistry or haematology (high mean cell volume or low platelets) on routine screening.

Complications of liver disease include liver cell failure and portal hypertension. Hepatic encephalopathy tends to develop insidiously as liver cells fail, and a history of mood change, confusion and somnolence is often obtained from the family. Portal hypertension may be associated with a history of abdominal swelling and peripheral oedema, but the patient may become aware of this only when they have difficulty in putting on their shoes or trousers. Gastrointestinal blood loss may indicate the presence of oesophageal varices or reflect a coagulation defect caused by liver disease or associated thrombocy-topenia. Key symptoms in liver disease are summarised in Table 62. It is important in the history to ask about: • previous jaundice - hepatitis or gallstones
