Osteoporosis and Obesity: The Relationship Between Obesity and Osteoporosis.

| Osteoporosis and Obesity |
Both are diseases of multifactorial etiology, chronic course and significant morbidity and mortality related in economically developed societies.
It has been shown that the incidence of osteoporosis and hip fractures is reduced in obese subjects. At present, several epidemiological studies have shown a protective effect of overweight on the development of osteoporosis and the occurrence of osteoporotic fractures.
For this reason, it is important to understand the precise relationship between potentially modifiable factors such as body mass, and the development of osteoporosis.
Although osteoporosis is one of the most prevalent metabolic bone disease, is also a preventable disease, which involves mostly women from the fifth decade. It is known that peak bone mass is achieved between 30-35 years, and depends on genetic, nutritional, metabolic and physical activity.
After 40 years, women lose approximately 0.3% -0.5% of bone mass per year, up 3% -4% per year after menopause. It is accepted that the determinants of the quantity and composition of bone tissue are multifactorial genetics, sex, diet (fat, protein, calcium), endocrine factors (sex steroids, calcitriol), mechanical forces (physical activity, body weight) and exposure risk factors, such as corticosteroids.
The weight, one of the determinants of bone mass, has received an analysis of its components: fat. She supports more weight and obese have greater body mass than thin women, therefore, would have greater ability to preserve bone mass, also absorbs calcium more efficiently, because their bone remodeling system is more sensitive to parathyroid hormone; and uses the available calcium optimally, thus preserving bone mass.
