Abnormal Body Condition
Sarcopenia is the age-related loss of lean body mass (LBM) that occurs unrelated to disease. With age, the rate of protein catabolism often exceeds protein synthesis. This imbalance leads to progressive loss of lean body mass with loss of strength, diminished quality of life, and shorter life span.1 Although this condition occurs in both dogs and cats, it seems to be more clinically significant in cats.
There is no single known cause of sarcopenia. The multifactorial etiology of this slowly progressive condition includes inadequate intake of protein or calories, altered protein turnover with decreased protein synthesis and increased protein catabolism, chronic increase in
While nutrition cannot prevent sarcopenia, the earlier this condition is identified the more opportunity there is to help delay age-related changes in body weight and body composition of older pets.
Preserving LBM in aging cats enhances longevity: A longitudinal study of aging showed that non-obese cats had a 2% increased chance of survival for every 10-gram increase in LBM. 12
