[Micronutrient deficiencies in osteoporosis].

Osteoporosis is a disease characterized by a progressive reduction of bone mass and a simultaneous deterioration of skeletal microarchitecture leading to a loss of bone strength, resulting in bone fracture as consequence of even very low traumas. Osteoporosis has only recently been accorded growing clinical and pathological importance for its impact on health. This disease, thanks to considerable increases in life expectancy, is becoming more visible and is now treated either as a serious public health issue of socio-economic importance, and as a multifactorial disease. In fact, both in women and men, osteoporosis is often associated with e hypogonadism as well as with individual traits such as genetic constitution, cytokines, sex and race, which represent non-modifiable endogenous risk factors. In addition, modifiable exogenous risk factors related to lifestyle (e.g. smoking, alcohol consumption, diet) can lead to an acceleration in the genesis of osteoporosis. This article is intended to contribute to the knowledge of exogenous risk factors in osteoporosis, with special consideration to the role of micronutrient deficiencies.
