Liver and gallbladder diseases - for example gallstones, jaundice, hepatitis, and alcohol-related conditions - are extremely common throughout the world. This book aims to present the facts as they are currently known, in a clear and non-technical way. It covers the normal function of the liver and gallbladder, describes the tests used to detect abnormality, and outlines, the major diseases. It discusses available treatment, and answers the questions most frequently asked by patients and relatives. This new edition has been expanded and re-written to cover the considerable advances in knowledge since 1987 - particularly in relation to gallstones, viral hepatitis, and liver transplantation. A section on self-help groups and charitable organizations has been added.
