An introductory discussion of the definitions of obesity and its epidemiology is followed by a detailed section on pathophysiology and aetiology, including genetic predisposition and appetite regulation, in addition to common environmental and lifestyle factors and ethnicity. Obesity at all ages is presented, with associated comorbidities and complications clearly illustrated. The authors proceed to discuss the much neglected area of management, approaching this area by defining the need to effectively assess the causes of the condition in the patient, giving advice on differential diagnosis, diet and exercise, behavioural therapy, surgery and pharmacological treatment. The atlas concludes with a summary of hospital care of the morbidly obese, and looks at promising future therapies, including preventative measures. Provides an illustrated, comprehensive review of obesity - a health problem that is rapidly becoming widespread in both developed and developing nations.
