Sarcopenia and Age-Related Muscle Loss

Posted on 06/16/2026 by San Gabriel Valley Medical Center

Have you noticed that standing up from a chair takes a little more effort than it used to? Or perhaps carrying groceries, climbing stairs, or keeping your balance feels more challenging than before.

While many people assume these changes are simply a normal part of aging, they may actually be signs of a condition called sarcopenia—the gradual loss of muscle mass and strength that commonly occurs as we get older.

What Is Sarcopenia?

Muscles do much more than help us lift heavy objects. They play an important role in maintaining balance, preventing falls, supporting mobility, and helping us stay independent.

As we age, our bodies naturally lose muscle mass. After age 60, many adults lose approximately 1 to 2 percent of muscle each year. Over time, this loss can make everyday activities more difficult and increase the risk of falls and injuries.

Common Warning Signs

The symptoms of sarcopenia often develop gradually. Early signs may include:

• Difficulty carrying groceries or household items
• Trouble climbing stairs
• Needing to push yourself up from a chair using your hands
• Feeling weaker or more tired than usual
• Slower movement
• Poor balance or feeling unsteady

Because these changes can happen slowly, many people do not recognize them right away.

Why Does It Happen?

Aging is one of the main causes of muscle loss, but other factors can contribute as well. A sedentary lifestyle, inadequate protein intake, chronic medical conditions, and prolonged hospital stays may all accelerate muscle loss.

Who Is Most at Risk?

Sarcopenia becomes more common after age 60. Individuals who spend much of their day sitting, do not exercise regularly, or consume insufficient protein may face a higher risk. People recovering from illness or lengthy hospitalizations may also be more vulnerable.

Steps You Can Take Today

The good news is that sarcopenia is not something you simply have to accept. There are several ways to help maintain muscle strength and function:

Stay active. Regular movement throughout the day can help preserve muscle mass. Walking, gardening, and household activities all count.

Try strength training. Light weights, resistance bands, or bodyweight exercises performed two to three times per week can help build and maintain muscle.

Eat enough protein. Foods such as fish, chicken, eggs, beans, tofu, and yogurt provide important nutrients that support muscle health.

Start small. Even a few minutes of activity each day can make a meaningful difference when practiced consistently.

When to Talk to Your Doctor

If you have noticed increasing weakness, balance problems, or difficulty performing everyday tasks, consider discussing these concerns with your healthcare provider. Early evaluation and intervention may help slow muscle loss and improve quality of life.

Staying Strong for the Future

Losing muscle strength is common with aging, but it is not inevitable. By staying active, eating a balanced diet, and addressing concerns early, you can help maintain your strength, mobility, and independence for years to come.
