About the book
Total body weight is the sum of the weight of all body components. Among these components, water, adipose tissue, muscle, and bone represent relevant contributors. The physiological or pathological variations in the amount or mass of each component can lead to an increase or a decrease in total body weight. These variations are increase (retention) or decrease (dehydration) in water amount, increase (hypertrophy, hyperplasia) or decrease (lipodystrophy) in adipose tissue mass, increase (hypertrophy) or decrease (sarcopenia) in muscle mass, and increase (increased bone density) or decrease (osteopenia, osteoporosis) in bone mass. A variety of causes including genetic factors, lifestyle, environment, aging, diseases, and medications can promote these conditions. There is a risk of increased morbidity (e.g., obesity, type 2 diabetes, and fracture) and mortality associated with some body weight variations.
This book intends to provide the reader with a comprehensive overview of the current knowledge about the pathophysiology, consequences, complications, and treatment of different types of body weight changes with special emphasis on preventive measures.
