What is Sarcopenia?
Sarcopenia is a severe condition, more common in older adults than young individuals. It causes gradual loss of muscle mass and strength. The syndrome is often associated with age, usually due to natural aging.
Studies show that in adults aged 60 or older, it has a prevalence of 5-13%, while for those aged 80 years or older, it ranges from 11-50%.
Sarcopenia has adverse effects on your daily activity and quality of life. Patients struggle to walk, climb stairs, and carry heavy items. In addition, some individuals may also have an increased risk of falls and fractures.
Sarcopenia diagnosis includes a series of tests. These tests help in checking muscle mass, quality, and physical performance.
Moreover, there aren’t t any approved medications for treating Sarcopenia. However, a few lifestyle and dietary choices can mitigate the risk of Sarcopenia and muscle loss.
How Sarcopenia Affects Your Body?
Sarcopenia impacts your body by causing a reduction in both the quantity and size of muscle fibers. As a result, muscles start to thin (a condition called muscle atrophy).
The aging process presents unique changes that raise the risk of Sarcopenia. For example, your body cannot produce enough proteins for muscle growth. As a consequence, muscle cells decrease in size.
In addition, age-related shifts in hormones also play a role. For example, testosterone and insulin growth factor (IGF-1) decline affects muscle fibers. It also raises the likelihood of the onset of Sarcopenia.
Symptoms of Sarcopenia
Sarcopenia, the muscle wastage in the elderly, often comes with many noticeable symptoms. Here are critical indicators to be aware of:
- Muscle Weakness: A prominent sign of Sarcopenia is a gradual muscle mass loss after 60. Once easy tasks may become more challenging. You may find it hard to carry objects or get up from a seated position.
- Reduced Stamina: Sarcopenia patients may experience a decrease in overall endurance. Activities that used to be manageable may now lead to fatigue.
- Difficulty in Mobility: Wasting syndrome limits mobility in the elderly. Individuals need help to perform everyday movements like walking or climbing stairs.
- Changes in Gait: A person with muscle mass loss might witness changes in their walking pattern, including a slower pace or a shuffling gait.
- Increased Risk of Falls: Muscle wastage in the elderly leads to a higher risk of falls. They experience difficulty in maintaining balance.
What Causes Muscle Wastage in the Elderly (Sarcopenia)?

The natural aging is the primary cause of muscle wastage in the elderly. It triggers a gradual decline in muscle mass and strength in one’s 30s or 40s.
This decline further speeds up between the ages of 65 and 80. Individuals can lose up to 8% of muscle mass per decade. While everyone experiences some muscle loss with age, those with Sarcopenia may undergo a swifter decline.
In addition to aging, many other factors can cause muscle mass loss after 60. These risk factors may include:
Insulin Resistance
As we age, our bodies gather more fat and lose muscle mass. Such changes can lead to conditions linked to insulin resistance.
This means our bodies may struggle to use insulin properly, causing issues with how we process sugars. It makes our body’s communication system rusty.
Insulin’s inability to do its job well might contribute to metabolic issues. It makes our bodies less efficient at handling insulin and increases the likelihood of Sarcopenia.
The decline in Hormone Levels
Advancing age affects the efficiency of particular hormones within the human body. The levels of anabolic hormones and insulin-like growth factor-1 start to decline. It messes with human growth hormone, and testosterone can drop.
These hormones are critical as they help with muscle growth and keep them strong. However, when they decrease, it is like losing some of our muscle defenders, increasing the risk of Sarcopenia.
Inflammatory Markers
Inflammatory markers like interleukin (IL)-6, tumor necrosis factor-alpha, C-reactive protein, and IL-1 can all rise with age. The rise of these markers can cause a decline in muscle mass.
These markers act as messengers. When their activity increases, it triggers chronic inflammation. As a result, our skeletal muscles lose their ability to work correctly.
Moreover, this chronic inflammation is critical in declining muscle strength, raising the risk of Sarcopenia. Effective management of these inflammatory markers is crucial to safeguard muscle strength.
Neurodegeneration
The natural aging process also results in neurodegeneration. It involves decreased peripheral nerve fibers, motor neurons in the spinal cord, and neuromuscular junctions.
These changes in the neurological system raise the risk of wasting syndrome in the elderly (Sacropenia). As we age, these essential components of nerve-muscle communication start to decline.
This gradual loss becomes a contributing factor to age-related muscle loss. These changes can influence Sarcopenia, where muscles lose their mass and strength.
Risk Factors for Sarcopenia
A sedentary lifestyle and not eating enough protein are two main culprits. In addition, being overweight could also be a factor.
But guess what? Even younger people can develop Sarcopenia. Young adults with inflammation, malnutrition, or extreme weight loss are more at risk.
Some other conditions linked to wasting syndrome in the elderly include:
Obesity
Obesity in older adults refers to having excess body fat. It is often measured through a body mass index (BMI) calculation. While Sarcopenia and obesity may seem like opposites, they can coexist in a condition known as sarcopenic obesity.
The condition occurs when you have decreased muscle mass and increased body fat. This mix creates a unique challenge, as excessive fat can mask the loss of muscle mass, making it harder to identify.
Moreover, extra body fat (obesity) can make Sarcopenia worse in a few ways. For example, excess fat can trigger chronic inflammation. As a result, it messes up muscle functions and triggers loss of muscle mass. In addition, obesity also causes insulin resistance, which can further decline muscle strength.
Chronic Obstructive Pulmonary Disease (COPD)
In 56 studies meeting specific criteria, it was found that 27% of people with COPD had Sarcopenia. COPD is a condition where muscle mass and function decline gradually. In addition, it also triggers inflammation, making it more likely for Sarcopenia to happen.
Moreover, the study shows that about one in four people with COPD might face Sarcopenia. Thus, COPD patients should focus on overall health to manage both breathing issues and the risk of Sarcopenia.
Rheumatoid Arthritis
Some studies suggest that about 66% of Rheumatoid arthritis patients experience Sarcopenia. It heightens the risk of falls and fractures and aids muscle wastage in older adults due to inflammatory processes.
Patients with RA may experience severe consequences. These include disability, a disrupted quality of life, osteoporosis, dyslipidemia, and cardiovascular complications.
The inflammatory nature of RA contributes significantly to the development of Sarcopenia. Thus, early diagnosis and prevention are critical. It can help prevent serious complications linked with muscle loss.
How to Prevent Muscle Wastage in the Elderly (Sarcopenia)?

Here are a few quick tips to reduce the risk of wasting syndrome in the elderly:
Increase Your Protein Intake
Protein is critical for muscle strength. It plays a crucial role in both building and maintaining muscle mass. When you eat protein, your body transforms it into amino acids (called the building blocks of protein).
These essential amino acids are then utilized to repair and regenerate muscle tissue: physical activity, especially resistance training or exercise, challenges muscles. So, the risk of small amounts of muscle damage can occur.
Protein offers the essential amino acids for the repair process and helps you increase muscle mass.
Eat More Vitamin D and Omega-3
In addition to protein, Vitamin D and Omega-3s are also essential for muscle mass. Eat foods with omega-3 fatty acids, like tuna, salmon, and sardines. These nutrients do a great job of reducing inflammation and keeping your muscles strong.
Moreover, ensure you get the correct Vitamin D to build and maintain muscle growth.
Weight Resistance Exercise
Resistance exercise is an excellent way to stop muscle wastage. You can lift weights with handheld dumbbells, weight machines, or elastic bands.
These exercises challenge your muscle fibers and stimulate protein synthesis. Consistent and proper resistance training prevents muscle atrophy. —the decrease in muscle size and strength.
In addition, resistance training preserves existing muscle mass and enhances muscle function.
Regular Walking
Fight muscle wastage by adding daily walks to your routine. While this is a simple strategy, the results are excellent. A daily walk keeps your muscles engaged and plays a role in maintaining strong bones.
Moreover, walking is a gentle exercise that gets different muscles moving, improving circulation and flexibility. Rhythmic motion mainly works leg muscles, making them stronger and more resilient.
Also, walking supports bone health by stimulating bone density and helping prevent osteoporosis. This easy and doable exercise is critical in preventing muscle mass loss.

Can You Reverse Sarcopenia?
Good news for older adults – muscle loss, known as Sarcopenia, can be reversed!
One study from Japan found that seniors who walked for six months increased their muscle mass. Another study shows that walking fast lowers the chances of developing Sarcopenia.
So, how much exercise is good for older adults?
The National Institute of Health recommends about half an hour of training twice a week. This kind of exercise boosts muscle mass and helps maintain strong bones. In addition, it also lowers the risk of falls and reduces injury chances if a fall happens.
Besides exercise, what you eat matters. Foods rich in protein, like chicken, salmon, Greek yogurt, skim milk, or beans, can make a big difference. Creatine, an affordable supplement, also enhances the benefits of resistance training.
And remember about the Omega-3 fatty acids found in foods like salmon. They are suitable for your heart and help with muscle growth and fight inflammation. Combining these steps allows you to take charge, reverse muscle loss, and boost your health and well-being.
Wrapping Up: Muscle Wasting Syndrome in the Elderly (Sarcopenia)
That is all about muscle wastage in the elderly (Sarcopenia). Fight Sarcopenia as you age by taking simple steps. Add regular strength exercises to your daily routine and ensure a balanced, protein-rich diet.
By acting now, you build a strong defense against Sarcopenia in the years ahead. In addition, talk with your healthcare provider about the best ways to shield your body from frailty. Prevent falls by prioritizing the development of healthy muscle mass.
As you age, these actions empower you to maintain muscle strength, resilience, and well-being. Remember, there is always time to start. These measures will contribute to a healthier, more robust you in the long run.
FAQs
Why do we lose muscle mass after 80?
Our bodies experience natural changes as we age, especially after eight decades. One reason for muscle strength loss is reduced physical activity and hormonal changes. With age, there is a decrease in hormones like testosterone, which is crucial for muscle health.
Additionally, lifestyle factors contribute to less exercise and poor nutrition. Muscles need regular use and proper nutrients to stay strong. Genetics also play a role; some people might be more prone to muscle loss. However, an active lifestyle, a balanced diet, and physical activity can help slow down muscle loss.
What is muscle protein synthesis?
Creating new muscle protein is called muscle protein synthesis. The rates of making new muscle proteins and breaking down existing ones decide the balance and changes in muscle mass.
It is a crucial part of how our bodies build and maintain muscles. So, when muscle protein synthesis is active reasonably, it promotes muscle strength and growth.
What does the term “lean body mass” mean?
Lean body mass is the weight of muscles, bones, ligaments, tendons, and internal organs. It is different from fat-free mass, which excludes fat. Lean body mass has some essential fat in the bone marrow and organs. So, it gives you a more accurate picture of your body’s non-fat components. Understanding lean body mass helps assess overall health and fitness. It focuses on the essential elements that keep your body strong and working well. Knowing this enables you to make choices that support a healthy and functional body.
Which vegetables can help increase muscle mass?
Vegetables can help reduce the risk of muscle wastage. Veggies like spinach, broccoli, and kale have vitamins, minerals, and antioxidants. These nutrients support muscle strength by aiding in recovery and reducing inflammation.
In addition, they provide essential fiber, promoting digestive health and ensuring proper nutrient absorption. Potatoes and sweet potatoes offer energy-boosting carbohydrates, crucial for muscle function. Adding colorful veggies to your diet provides a mix of nutrients contributing to muscle growth.
What is the function of muscle tissue?
Muscle tissue is essential in our bodies as it helps us move! When we eat food, the body breaks it down into proteins, and muscle tissue uses these proteins to grow and repair. Think of muscle tissue like the engine powering your movements. Your muscles, whether running, lifting, or walking, are stiff at work. In addition, muscle tissue also supports our bones and helps us maintain good posture.
What types of resistance training can increase muscle mass?
Resistance training, like weight lifting or resistance bands, can increase muscle mass. When you engage in these activities, your muscles work against resistance, stimulating them to grow more substantial. This type of training is like giving your muscles a workout, making them adapt and become more robust over time. To increase muscle mass, incorporating resistance training into your routine is a great way to achieve your fitness goals.
