Sarcopenia: Causes of muscle loss and solutions refers to the gradual loss of muscle mass, strength, and function, most commonly associated with aging. It can affect balance, mobility, independence, and the risk of falls.
Common causes of sarcopenia
- Aging
- After about age 30, adults gradually lose muscle mass, and the rate of loss often increases with older age.
- Lack of physical activity
- Long periods of sitting or inactivity can accelerate muscle loss.
- Inadequate protein intake
- Not getting enough protein can make it harder for the body to maintain and repair muscle.
- Hormonal changes
- Age-related changes in hormones such as testosterone, estrogen, and growth-related hormones can affect muscle maintenance.
- Chronic illnesses
- Conditions such as diabetes, heart disease, kidney disease, and inflammatory disorders can contribute to muscle decline.
- Poor nutrition or weight loss
- Unintentional weight loss can reduce both fat and muscle tissue.
Ways to help prevent or slow muscle loss
1. Strength training
- Resistance exercises (weights, resistance bands, body-weight exercises) are among the most effective ways to build and preserve muscle.
- Training should be adapted to a person’s fitness level and health conditions.
2. Eat enough protein
- Protein-rich foods include:
- Eggs
- Fish
- Lean meats
- Dairy products
- Beans and lentils
- Soy products
- Older adults may need to pay extra attention to getting adequate protein spread throughout the day.
3. Stay physically active
- Walking, balance exercises, and regular movement support overall function.
4. Get enough vitamin D
- Low vitamin D levels can be linked with poorer muscle function in some people. Testing and supplementation decisions should be discussed with a healthcare professional if deficiency is suspected.
5. Address underlying health problems
- Managing chronic conditions, sleep quality, and nutrition can support muscle health.
When to seek advice
A healthcare professional can help evaluate possible sarcopenia if there is:
- Increasing difficulty climbing stairs or rising from a chair
- Frequent falls
- Noticeable loss of muscle strength
- Unintentional weight loss
Sarcopenia is not an unavoidable part of aging; maintaining regular resistance exercise, adequate nutrition, and an active lifestyle can make a significant difference.
