Loss of muscle mass - Rejuvenate Clinic

What is loss of muscle mass?

Loss of muscle mass, also known as muscle atrophy, occurs when muscle fibers shrink and weaken over time. This leads to a decrease in muscle strength and function. Some key points about muscle atrophy:

• It can happen due to lack of physical activity, poor nutrition, aging, illness, or injury. During periods of inactivity, your body breaks down muscle proteins to use for energy.
• Sarcopenia is the age-related loss of muscle mass that begins in your 30s and progresses with aging. Up to 3-5% of muscle mass may be lost per decade after 30.
• Muscle atrophy can occur locally - affecting just one muscle or muscle group - or it can be widespread, affecting muscles throughout the body.
• Major causes include immobilization due to injury or illness, malnutrition, chronic diseases, and the natural aging process.

Common signs and symptoms:

• Decreased muscle strength
• Impaired mobility or balance
• Fatigue, weakness
• Higher risk of falls or fractures
• Weight loss

Risk factors include:

• Advanced age (60 )
• Sedentary lifestyle
• Poor nutrition - low protein intake
• Chronic health conditions
• Prolonged bed rest

Prevention and treatment focuses on:

• Engaging in regular resistance training and weight-bearing/muscle-loading exercise
• Eating a nutritious, protein-rich diet
• Treating underlying medical issues
• Some medications may help alleviate muscle loss as well

The takeaway is that muscle atrophy can negatively impact strength, function, stamina and quality of life. Staying physically active with a proper diet can help preserve muscle as you age. See your doctor if you have ongoing, unintentional muscle loss or weakness. Early intervention may help stop or slow further wasting.
