Does your body lose its strength as you age? It could be sarcopenia!

Do you feel like your limbs are getting weaker as you get older, and you don't have the strength to do the things you used to? Do you find it difficult to walk? You may think that this is a normal part of aging. However, it could also be a symptom of a condition called "sarcopenia." Let's talk about this a little bit today, because it affects many people, but it's something that isn't often talked about.

What is sarcopenia? Simply put...

Simply put, sarcopenia is the gradual loss of muscle mass and strength as we age. Think of it this way: our muscles are like the bricks used to build a house. Over time, these bricks wear out and the strength of the house decreases. This condition affects older people the most. But it's not just about getting older. It can make it harder to do everyday tasks and reduce the quality of life. Sometimes, this can lead to people becoming dependent on others and requiring long-term care.

The most important thing is that sarcopenia increases the body's weakness, and the chances of frequent falls and fractures are also higher. When these things happen, you have to face things like hospitalization and surgery. Then more complications arise, and sometimes even life-threatening.

Sarcopenia can also occur in people with a high body mass index (BMI). This is called "sarcopenic obesity." The complications associated with both conditions are greater than those caused by obesity alone, or sarcopenia alone.

Who gets sarcopenia?

This condition is most common in people over 60. The risk of developing it increases with age. It can affect both men and women equally. The results of studies on how it affects different ethnic groups are not very consistent. Also, this condition is more common among people with chronic diseases. Think about our neighbor, Uncle Nimal. He used to be a man who ran around and worked a lot? Now he is about 65 years old. He says, "Now I can't even climb stairs like I used to, kids. It's very difficult to go to the store." Perhaps Uncle Nimal has also been affected by this condition.

How common is this?

In fact, the results of studies on this topic are mixed. Many people do not recognize this condition or seek treatment. However, it is estimated that between 5% and 13% of people over the age of 60 have this condition. Among people over the age of 80, this number can be as high as 11% to 50%. This means that it is more common than we think.

How does sarcopenia affect my body?

Our muscles are made up of muscle fibers. Sarcopenia is a condition where the number and size of these muscle fibers decrease. The muscles then become weaker. This is also called "muscle atrophy." As we age, certain changes occur in our bodies. These changes are the main cause of sarcopenia. For example, our bodies do not produce the proteins needed for muscle growth as we age. When this happens, muscle cells shrink. In addition, as we age, changes in hormones like testosterone and insulin-like growth factor-1 (IGF-1) affect our muscle fibers. This is also a cause of sarcopenia.

What are the symptoms of Sarcopenia?

The most common symptom is muscle weakness. Other symptoms may include:

• Loss of stamina.
• Difficulty performing daily tasks . Feeling tired even doing small tasks.
• Walking slowly. I can't walk as fast as I used to.
• Difficulty climbing stairs.
• Loss of balance and frequent falls.
• Decreased muscle mass. Limbs feel weak.

If your grandmother or grandfather has these characteristics, you should be a little concerned about it.

What are the causes of sarcopenia?

The most common cause is natural aging. We all start to lose muscle mass and strength gradually in our 30s or 40s. This process accelerates between the ages of 65 and 80. Although the rate of loss varies from person to person, muscle mass can decrease by as much as 8% per decade. Everyone loses muscle over time, but this happens much more quickly in people with sarcopenia. While aging is the main cause, researchers have identified several other risk factors that may contribute to the development of sarcopenia. These include:

• Not being physically active. Sitting in one place, not exercising.
• Obesity . Being overweight.
• Chronic diseases . For example, chronic obstructive pulmonary disease (COPD),Kidney disease , diabetes , cancer and HIV infection.
• Rheumatoid arthritis.
• Insulin resistance.
• Decreased hormone levels.
• Malnutrition or not getting enough protein.
• Decreased ability to convert protein into energy.
• A decrease in the number of nerve cells that send messages from the brain to the muscles to move.

How is Sarcopenia diagnosed?

Your doctor may examine you and ask about your symptoms to see if you have sarcopenia. They may also ask you to fill out a questionnaire called the SARC-F . This is a self-report questionnaire about your symptoms. The SARC-F is:

• S — Strength
• A — Assistance with walking (Need help with walking?)
• R — Rising from a chair (Is it difficult to get up from a chair?)
• C — Climbing stairs (Is it difficult to climb stairs?)
• F — Falls (Do falls happen?)

Each of these factors is given a score between 0 and 2. The maximum score is 10. If the SARC-F score is 4 or more, further testing is required.

What are the tests used to diagnose sarcopenia?

There is no single test to diagnose this. Your doctor may order several tests to help diagnose the condition and determine its severity.

Tests that measure muscle strength:

• Handgrip test: The strength of the hand to grip something firmly can give an idea of ​​the strength of the other muscles in the body.
• Chair stand test: This measures muscle strength in the legs, especially the thighs. It measures how many times you can stand up from a chair and sit down again without using your hands within 30 seconds.
• Walking speed test: This measures how long it takes you to walk 4 meters (about 13 feet) at your normal walking speed.
• Short Physical Performance Battery (SPPB): This consists of three timed tasks: a chair-rising test, a standing balance test, and a walking speed test.
• Timed-up and go test (TUG): The time it takes to get up from a chair, walk 3 meters (about 10 feet) away from the chair, walk 3 meters back to the chair, and sit back down is measured.

Imaging tests that measure muscle mass:

• Dual-energy X-ray absorptiometry (DEXA or DXA - Dual-energy X-ray absorptiometry):This uses low-energy X-rays to measure your muscle mass, fat mass, and bone density.
• Bioelectrical impedance analysis (BIA): This test is less expensive and easier to perform than DEXA. It measures your body fat in relation to your lean body mass.

How is sarcopenia treated?

Sarcopenia is usually treated by making lifestyle changes . These changes can help manage and even reverse the condition to some extent.

• Physical activity: Your doctor may recommend progressive resistance-based strength training . This type of exercise can help you build strength and reverse muscle loss. Think of it like lifting weights.
• Healthy Diet: Along with regular exercise, eating a healthy diet can also help reduce the effects of sarcopenia. It is especially important to get enough protein, whether from food or supplements .

What are the medications for sarcopenia?

Researchers are still investigating whether hormone supplements can increase muscle mass. However, there are currently no FDA-approved medications to treat sarcopenia.

Can sarcopenia be prevented?

This is part of the natural aging process, so it cannot be completely prevented. However, there are some things we can do to slow down the progression of this disease. These are:

• Healthy Food Choices: Maintain a healthy diet that includes foods that contain high-quality protein . Aim for 20 to 35 grams of protein per meal.
• Exercise: Maintain a physically active lifestyle, including exercise such as resistance training .
• Regular medical checkups: See your doctor regularly . Tell him or her if there are any changes in your health.

What happens if I have sarcopenia?

The outlook for sarcopenia depends largely on your age. The condition can get worse as you get older. In addition, it also varies depending on your health and lifestyle. This disease can have a significant impact on your quality of life. You may be able to reverse the effects of this condition by making lifestyle changes.However, if you don't make the recommended changes, the disease will continue to weaken your muscles. Over time, you may need full-time care to function in your life.

Is sarcopenia a disease?

In 2016, the Centers for Disease Control and Prevention (CDC) gave the condition an International Classification of Diseases (ICD-10) code, declaring sarcopenia a separate disease. This made it a reportable condition for doctors. This led to increased recognition and treatment of the condition. This labeling allowed researchers to distinguish it from similar diseases such as sarcopenia and to begin collecting valuable data about the condition.

What is the difference between Sarcopenia and Muscle Atrophy?

Sarcopenia is a type of muscle atrophy. It especially affects older people. Muscle atrophy is the loss of muscle tissue. Although both conditions share the common characteristics of muscle loss, the underlying mechanisms are different. Sarcopenia occurs when the size and shape of muscle fibers decrease. In muscle atrophy, the size of the fibers decreases, but the number of fibers remains the same.

Everyone loses some muscle mass as they age. But in sarcopenia, this loss of muscle mass occurs much more rapidly. The good news is that there are ways to treat this condition and reverse its effects.

Finally, things to remember (Take-Home Message)

If you have muscle weakness, a limp, or any other symptoms of sarcopenia, be sure to see your doctor. He or she can diagnose the condition and develop a treatment plan that is right for you. This can help you manage muscle loss and improve your condition. Remember, although aging cannot be stopped, we can greatly reduce the effects of conditions like sarcopenia by living a healthy lifestyle , which means eating well and exercising regularly . So, take care of your body. Take care of the elderly you love. Sarcopenia, muscle weakness, aging, loss of muscle mass, exercise, protein
