Muscle Wasting Ailment: Root Causes, Signs, and Strategies for Treatment
Sarcopenia, the natural, aging-induced loss of muscle mass, can leave folks feeling feeble and unstable. This decrease in muscle strength impacts an individual's daily activities, like climbing stairs, lifting objects, and strolling around.
Here's the scoop on sarcopenia causes, symptoms, diagnosis, treatment, and how you can take control and fight back!
Sarcopenic Emergence and Progression
The International Osteoporosis Foundation (IOF) reveals that muscle mass diminishes around the age of 40, and the decline may accelerate as folks reach their 60s and 70s. The exact rate of loss varies, with an average decrease of 3-8% of muscle mass per decade. As you age, muscle fibers start to decrease in quantity and size, leading to atrophy or shrinking of the muscles.
As time passes, your body's protein production ability dwindles, causing individual muscle cells to shrink. Aging-related hormonal changes, such as reducing testosterone and insulin-like growth factor (IGF-1) levels, may also contribute to the loss of muscle mass.

Risk Factors
Besides aging, factors that boost the risk of sarcopenia include:
- A sedentary lifestyle
- Poor nutrition
A sedentary lifestyle increases your likelihood of developing sarcopenia, making regular physical activity a must. Don't forget that poor nutrition can be detrimental as well, with older adults at greater risk of malnutrition due to reduced food intake. According to IOF data, up to 41% of women and 38% of men above 50 may eat less protein than the recommended daily allowance. Consuming excessive acid-producing foods, such as grains and processed foods, and inadequate vegetables and fruits, can negatively impact muscle mass.
Sarcopenia Symptoms
Symptoms of sarcopenia vary in intensity, with possible signs of:
- Diminished muscle size
- Weakness
- Loss of endurance
- Poor balance
- Struggle with climbing stairs
Although muscle loss may not seem critical, it can lead to weakness, increased fall risk, and reduced independence. Sarcopenia may also diminish an individual's motivation to participate in physical activities, worsening the situation and negatively impacting quality of life.
Diagnosing Sarcopenia
Doctors rely on a combination of the symptoms an individual reports and diagnostic tests such as a dual energy X-ray absorptiometry (DXA) and a walking speed test to diagnose sarcopenia. DXA measures bone density and may be used alongside a walking speed test to enhance the diagnosis' accuracy. Additional tests, such as handgrip strength measurements, may also be performed.
Treatment and Management
Currently, there are no FDA-approved medications for sarcopenia treatment. Researchers study the potential benefits of hormone therapy, including testosterone and growth hormones, to help people maintain muscle mass as they age. More studies are needed to assess the efficacy and safety of hormone therapy for this purpose.
Managing sarcopenia requires lifestyle adjustments to prevent muscle loss. Key measures focus on:
Exercise
Incorporating regular exercise, particularly strength training, helps maintain and build muscle mass. Weight-bearing and resistance training exercises are beneficial, and activities like walking, climbing stairs, dancing, lunges, push-ups, and squats are good choices. Aim for at least 30 minutes of moderate-intensity exercise daily or around 150 minutes weekly, combining aerobic, balance, and strength training for improved muscle and bone health[1][3][4].
Nutrition
Proper nutrition is essential for managing sarcopenia. Increasing protein intake to support muscle repair and growth is crucial. Aim for about 20–30 grams of protein per meal, including sources like eggs, fish, chicken, beans, milk, and nuts[1][3]. Maintaining adequate vitamin D and magnesium levels also aids muscle function and supports protein utilization[1][3]. Consuming muscle-supportive fruits such as blueberries, bananas, and sour cherries can further improve recovery and performance[2].
Dietary Supplements
Supplements may be useful in filling nutritional gaps if your diet is inadequate. Consult a healthcare provider before starting supplements to tailor them to individual needs and avoid contraindications[1][3].
The Bright Side
While aging is inevitable, developing sarcopenia doesn't have to be. With consistent lifestyle changes that include regular exercise, a protein-rich diet, adequate hydration, and suitable supplements, people can manage sarcopenia and improve their overall health and well-being.
- Sarcopenia, the natural loss of muscle mass due to aging, can make seniors feel weaker and less stable.
- The International Osteoporosis Foundation reports that muscle mass decreases around age 40 and may speed up in the 60s and 70s, with an average loss of 3-8% per decade.
- Aging leads to a decrease in muscle fibers' quantity and size, resulting in muscle atrophy or shrinking.
- As we age, our bodies produce less protein, causing individual muscle cells to shrink.
- Hormonal changes associated with aging, including reduced testosterone and insulin-like growth factor (IGF-1) levels, may contribute to muscle loss.
- Maintaining a healthy lifestyle can help combat sarcopenia.
- Regular physical activity is crucial in reducing the risk of sarcopenia, making a sedentary lifestyle a risk factor.
- Older adults are more susceptible to malnutrition due to reduced food intake, increasing the risk of sarcopenia.
- Consuming excess acid-producing foods like grains and processed foods can negatively impact muscle mass.
- Adequate vegetable and fruit consumption is essential for maintaining muscle mass as we age.
- Symptoms of sarcopenia include diminished muscle size, weakness, loss of endurance, poor balance, and difficulty climbing stairs.
- Weakness, increased fall risk, and reduced independence are potential consequences of sarcopenia.
- Sarcopenia may discourage seniors from participating in physical activities, worsening the condition and negatively impacting quality of life.
- Doctors use a combination of symptoms reported by the individual and diagnostic tests such as DXA and walking speed tests to diagnose sarcopenia.
