As we age, our bodies undergo numerous changes, and one of the less discussed but impactful aspects is the loss of muscle mass and strength. Sarcopenia, often referred to as the "silent thief," is a condition characterized by the gradual loss of skeletal muscle mass, strength, and function. Let’s delve into the intricacies of sarcopenia, its causes, symptoms, diagnosis, and proactive measures to counteract its effects.
Sarcopenia stems from the Greek words "sarx," meaning flesh, and "penia," meaning loss. Essentially, meaning of sarcopenia is the loss of muscle mass and function associated with ageing. While a certain degree of muscle loss is a natural part of the ageing process, sarcopenia represents an accelerated and pathological decline that can impact an individual's overall health and quality of life.
As Sarcopenia mainly affects the elderly, the causes are also majorly age-related:
As individuals age, there is a natural decline in hormone levels, including testosterone and growth hormone, both of which play crucial roles in maintaining muscle mass. These hormonal changes contribute to the gradual loss of muscle tissue.
A sedentary lifestyle, common in older adults, can exacerbate muscle loss. Lack of regular physical activity, including resistance training and aerobic exercise, contributes to muscle atrophy and weakness.
Inadequate protein intake, along with deficiencies in essential vitamins and minerals, can compromise muscle health. Protein is particularly crucial for muscle synthesis, repair, and maintenance.
Persistent inflammation, often associated with conditions like arthritis or chronic diseases, can accelerate muscle wasting. Inflammation triggers the release of cytokines that promote muscle breakdown.
Aging also brings about changes in the nervous system, affecting the signals sent to the muscles. Reduced motor unit activation and impaired neuromuscular coordination contribute to muscle weakness.
A common occurrence with age, insulin resistance can negatively impact muscle protein synthesis and contribute to the development of sarcopenia. When you grow old, you become more susceptible to various health issues, which might cause great distress to you. Having the support of health insurance in your old age is important to deal with the constant changes your body goes through.

The progression of sarcopenia is often insidious, and symptoms may not be immediately apparent. However, as the condition advances, individuals may experience:
Gradual loss of muscle strength, especially in the legs and upper body, leading to difficulties in performing daily activities.
Individuals with sarcopenia may notice a decline in endurance and increased fatigue during physical activities.
Weakening of the muscles can affect balance and coordination, increasing the risk of falls and fractures.
Sarcopenia can contribute to unintended weight loss due to the loss of lean muscle mass.
Diagnosing sarcopenia involves a comprehensive evaluation by healthcare professionals. Some common assessment methods include:
Healthcare providers may assess muscle strength, function, and overall physical performance through various tests. If you are covered by critical illness insurance, check if the tests are covered by the policy. Claims are subject to terms and conditions set forth under health insurance policy.*
DEXA scans can measure muscle mass and identify areas of muscle loss, helping in the diagnosis of sarcopenia.
Functional tests, like the Timed Up and Go test or the 6-Minute Walk test, assess mobility, balance, and overall physical function.
One of the most common questions people ask is whether sarcopenia can be reversed. While sarcopenia cannot be entirely reversed, it can be managed and improved through various interventions. The earlier you begin addressing muscle loss, the better the chances for improvement. Although complete recovery of muscle mass may not always be possible, sarcopenia treatment can help maintain muscle strength, improve function, and enhance overall quality of life.
Effective treatments for sarcopenia focus on:
With consistent effort and a healthy lifestyle, significant improvements can be made.
If you notice sarcopenia symptoms such as significant muscle weakness or difficulty with daily activities, it’s essential to consult a healthcare professional. A doctor can help assess whether the muscle loss is due to sarcopenia or another underlying health condition. Seeking medical attention is particularly important if:
A health insurance policy can help cover medical costs for diagnostic tests, physiotherapy, and necessary treatments to manage the condition effectively.
Several factors can contribute to the acceleration of sarcopenia, causing it to develop at a faster rate:
Lack of exercise, particularly strength training and resistance exercises, is a major contributor to muscle loss. Without regular physical activity, muscles atrophy more quickly, leading to sarcopenia.
Inadequate protein intake, along with deficiencies in vitamins and minerals, can contribute to muscle breakdown. Nutrition plays a vital role in maintaining muscle health and strength.
Conditions like diabetes, heart disease, chronic kidney disease, and rheumatoid arthritis can contribute to muscle wasting due to inflammation and metabolic changes.
Decreased levels of hormones such as testosterone, estrogen, and growth hormone can impact muscle growth and maintenance, especially in older adults.
Long-term use of certain medications, like corticosteroids, can contribute to muscle loss. These medications can interfere with protein synthesis and promote muscle breakdown.
As people age, muscle mass naturally decreases, and muscle fibres shrink. Sarcopenia is often a natural part of the ageing process, particularly after the age of 60.
While sarcopenia is more common among older adults, it can affect people of any age, especially when other contributing factors are present. Here's who is most likely to experience sarcopenia:
The condition is most prevalent in individuals over 60 years of age, particularly those who are sedentary, have poor nutrition, or suffer from chronic illnesses.
Individuals living with conditions such as diabetes, cancer, and neurological disorders are at increased risk of developing sarcopenia due to chronic inflammation and metabolic changes.
Lack of regular physical activity accelerates muscle atrophy. Those with inactive lifestyles are more likely to experience muscle loss earlier than those who stay active.
The reduction in estrogen levels after menopause contributes to muscle mass loss in women, making them more susceptible to sarcopenia.
Inadequate protein intake, particularly in the elderly, can lead to a faster decline in muscle mass. Proper nutrition is essential for preventing and managing sarcopenia.
While sarcopenia treatment is not one-size-fits-all, there are several approaches to manage the condition effectively:
Several factors increase the likelihood of developing sarcopenia:
The following tips can help in preventing the development of sarcopenia in your body:
Engaging in regular physical activity, including both resistance training and aerobic exercise, is crucial in preserving muscle mass and strength. Strength training exercises, such as weightlifting, can promote muscle growth and improve overall function.
Adequate protein intake is essential for muscle health. Consuming a well-balanced diet with sufficient protein, along with essential vitamins and minerals, can support muscle maintenance and repair.
In some cases, especially when hormonal imbalances contribute to sarcopenia, hormone replacement therapy may be considered under the guidance of healthcare professionals.
Routine health check-ups may allow for the early detection of conditions that may contribute to sarcopenia, such as hormonal imbalances or nutritional deficiencies.
Some medications may have side effects that contribute to muscle loss. Periodic reviews of medications with healthcare providers can help mitigate potential risks.
