Sarcopenia, a decline in skeletal muscle in older people, contributes to loss of independence.
I, like many people past 50, have a condition called sarcopenia — a decline in skeletal muscle with age. It begins as early as age 40 and, without intervention, gets increasingly worse, with as much as half of muscle mass lost by age 70.
“Sarcopenia can be considered for muscle what osteoporosis is to bone,” Dr. John E. Morley, geriatrician at Saint Louis University School of Medicine, wrote in the journal Family Practice. He pointed out that up to 13 percent of people in their 60s and as many as half of those in their 80s have sarcopenia.
A decline in physical activity, common among older people, is only one reason sarcopenia happens. Other contributing factors include hormonal changes, chronic illness, body-wide inflammation and poor nutrition.
