As we age, we start to lose muscle mass gradually. This is called sarcopenia.
Sarcopenia, a type of atrophy, is the age-related progressive loss of muscle mass, function, and strength.
Everyone loses muscle mass over time; however, people who have sarcopenia lose it more quickly. Sarcopenia usually begins around the age of 35 and accelerates between the ages of 65 and 80. Rates of this acceleration vary; however, as much as 8% of muscle mass is lost each decade.
The natural aging process is usually the main cause of sarcopenia as the body doesn’t produce the same number of proteins the muscles need to grow, which causes them to get smaller. However, researchers have discovered other possible risk factors of the condition, including:
· Physical inactivity
· Obesity
· Chronic diseases such as chronic obstructive pulmonary disease (COPD), kidney disease, diabetes, cancer, and HIV
· Rheumatoid arthritis
· Insulin resistance
· Malnutrition or inadequate protein intake
· Reduction in hormone levels
· Decrease in the ability to convert protein to energy
· Decline in the number of nerve cells that send messages from the brain to the muscles telling them to move
Sarcopenia affects the musculoskeletal system and is a major factor in increased frailty, falls, and fractures. These conditions can lead to hospitalizations and surgeries, which increase the risk of complications, including death.
This condition can also affect people with a high body mass index (BMI), which is called sarcopenic obesity. People suffering from obesity and sarcopenia have a greater risk of complications than those with obesity or sarcopenia alone.
The most common symptom of sarcopenia is muscle weakness. Other symptoms may include:
· Decrease in muscle size
· Difficulty performing daily activities
· Poor balance and falls
· Loss of stamina
· Trouble climbing stairs
· Walking slowly
A healthcare provider may diagnose sarcopenia after they perform a physical exam and ask you about your symptoms. They may also ask you to complete a questionnaire based on your self-reported symptoms called the SARC-F, which stands for:
· Strength
· Assistance with walking
· Rising from a chair
· Climbing stairs
· Falls
You score each factor with a number between 0 and 2, with the highest maximum and total SARC-F being 10. A SARC-F score of 4 or more warrants more testing.
There is no single test that can diagnose sarcopenia. A healthcare provider may recommend several tests to help diagnose and then determine the severity of sarcopenia. These tests include:
· Muscle tests:
- Handgrip test
- Chair stand test
- Walking speed test
- Short Physical Performance Battery (SPPB)
- Timed-up and go test (TUG)
· Imaging tests for measurement of muscle mass
- Dual-energy X-ray absorptiometry (DEXA or DXA)
- Bioelectrical impedance analysis (BIA)
The treatment for sarcopenia usually includes lifestyle changes, as they can treat and help reverse the condition. These lifestyle changes include:
· Physical activity, which includes resistance-based strength training
· A healthy diet
Sarcopenia is not fully preventable. However, there are steps you can take to slow the progression of the disease, including:
· Making healthy food choices
· Exercising regularly
· Attending routine physicals
