Sarcopenia, also known as age-related muscle loss, is a common occurrence as individuals grow older. With people living longer lives nowadays, sarcopenia has become a significant concern, impacting the overall health, well-being, and quality of life among the elderly population. However, it is important to note that muscle mass loss doesn’t have to be irreversible and can be effectively managed and prevented with proper care and attention.
Prevalence of Sarcopenia
As individuals age, the loss of muscle mass becomes increasingly common. Around the age of 30, people start to experience a gradual decline in muscle mass, losing approximately one-tenth to one-half percent per year. However, once they reach the age of 50, this rate of muscle loss escalates to one to two percent annually. Sarcopenia, the medical term for age-related muscle loss, affects a significant portion of the population. By the time individuals reach their 80s, as much as 50 percent of them may experience sarcopenia. Additionally, up to 33 percent of all individuals residing in long-term care facilities are affected by this condition.
Diagnosing Sarcopenia
Diagnosing sarcopenia involves assessing both muscle mass and muscle function. Medical professionals evaluate muscle function by observing the ability to stand with feet together, measuring the time taken to walk eight feet, and assessing the time required to rise from a chair and return to a seated position five times. On the other hand, determining muscle mass is more challenging and requires the use of MRI and CT scans. Additionally, researchers have discovered certain biomarkers that aid in the early detection of sarcopenia.
