Sarcopenia is a disease associated with the aging process. Loss of muscle mass and strength, which in turn affects balance, gait and overall ability to perform tasks of daily living, are hallmark signs of this disease. 



According to the International Osteoporosis Foundation, sarcopenia is a disorder related to advancing age and the condition is generally attributed to four key risk factors:

  • being of an age 40 years and older 
  • living a sedentary lifestyle, 
  • malnutrition or lack of adequate nutrition 
  • consuming a diet high in acid-producing foods 

    While each of these factors is distinct, they combine to produce an age-related loss of muscle coordination and overall muscle



    • Roughly 45% of the US population is sarcopenic
    • Sarcopenia affects balance, gait and overall ability to perform tasks of daily living 
    • Sarcopenia affects more than 50 million people today and will affect more than 200 million people in the next 40 years
    • In the United States, an estimated 53% of men and 43% of women over 80 are sarcopenic
    • People who are physically inactive can lose as much as 3 to 5 percent of their muscle mass per decade after age 30
    • After about age 50, muscle mass decreases at an annual rate of 1 to 2 percent.
    • Muscle strength also declines by 1.5% between ages 50 and 60 and by 3% thereafter
    • A study that has tracked 3,000 people for 50 years found that only about 20 of them, now in their 80s, have not lost muscle mass
    • No race or ethnicity is protected from sarcopenia
