This reference work by over 20 international experts addresses the important clinical problem of obesity by synthesising current scientific thinking about its background and metabolic consequences with clinical management. The opening section of the book covers, in a synoptic fashion, the basic science of obesity, genetics, metabolism, epidemiology and energy expenditure. The central section of the book looks at the medical complications of being obese such as hypertension, diabetes, lung function, fertility and pregnancy, and problems in obese children. The final section covers the various treatments available such as dietary control, drug treatment, surgery and psychological interventions, and also looks at the exciting new therapies likely to emerge in the next few years.
