This authoritative guide to good health is designed to give answers to every question you might want to ask your doctor, from understanding how your body works and why it sometimes goes wrong, to ways of keeping it in good order. The book is divided into two parts. Part I describes all phases and aspects of the human life cycle, giving extensive information on emotional as well as physical problems specific to critical points in life such as pregnancy and birth, adolescence and old age. Part II describes just how each system of the body works, how it sometimes goes wrong and how illness and disorders can be recognised and treated. Also included is information on diseases that affect the whole body, such as cancer, and on mental health and illness.
