Frailty and chronic diseases: A bi‐directional relationship

Abstract

Frailty is a multidimensional syndrome associated with a decline in reserve capacity across multiple organ systems involving physical, psychological, and social aspects. Weakness is the earliest indicator of the frailty process. Multi‐morbidity is the state of presence of two or more chronic diseases. Frailty and chronic diseases are interlinked as frail individuals are more prone to develop chronic diseases and multi‐morbid individuals may present with frailty. They share common risk factors, pathogenesis, progression, and outcomes. Significant risk factors include obesity, smoking, aging, sedentary, and stressful lifestyle. Pathophysiological mechanisms involve high levels of circulating inflammatory cytokines as seen in individuals with frailty and chronic diseases such as hypertension, cardiovascular diseases, type 2 diabetes mellitus, chronic kidney disease, and anemia. Hence, frailty and chronic diseases go hand in hand and it is of utmost importance to identify them and intervene during early stages. Screening frailty and treating multi‐morbidity incorporate both pharmacological and majorly non‐ pharmacological measures, such as physical activities, nutrition, pro‐active care, minimizing polypharmacy and addressing reversible medical conditions. The purpose of this mini‐review is to highlight the interrelation of frailty and chronic diseases through the discussion of their predictors and outcomes and how timely interventions are essential to prevent the progression of one to the other.
