LIC. REAL, Clarisa  and  DRA. PERALTA, Leticia. All roads lead to loss of muscle mass: malnutrition, frailty, sarcopenia and cachexia. Diaeta [online]. 2021, vol.39, n.174, pp.45-58. ISSN 1852-7337.

Chronic degenerative diseases have won great interest and value in the field of health due to the high global burden of morbidity and the high rate of disability that they generate. At the same time, the prevalence of malnutrition affects 40-60% of hospitalized patients, which implies an increase in health costs, greater morbi mortality and an increase in disability rates. Various concepts emerge in the literature in which the loss of muscle mass, disease and malnutrition are related. The objective of this article is to define the concepts of malnutrition, frailty, cachexia and sarcopenia. The aim was to describe its prevalence, to differentiate the mechanisms that generate each situation and its impact on body composition.

Keywords : malnutrition; cachexia; sarcopenia; fragility; muscle mass.
