What is Loss of Muscle?

Muscle loss, also known as muscle atrophy, occurs when muscle fibers shrink and weaken over time. This leads to a decrease in muscle mass and strength.

Causes

Major reasons for losing muscle mass include:

• Aging - As we get older, muscle fibers break down more quickly. Muscle mass declines 3-8% per decade after age 30.
• Inactivity - Not using your muscles accelerates muscle loss. Bedrest, cast immobilization, and low physical activity all contribute.
• Malnutrition - Consuming inadequate protein and calories leads to the breakdown of muscle for energy.

Consequences

Loss of muscle can negatively impact:

• Strength - Weakness makes daily activities like climbing stairs difficult.
• Mobility - Higher risk of falls and fractures when muscles cannot support the body.
• Metabolism - Less muscle mass slows resting metabolism, burning fewer calories.

Prevention

We can take steps to maintain muscle with aging and activity changes:

• Exercise regularly - Lifting weights and resistance training stimulate muscle building.
• Eat adequate protein - Consuming foods like meat, eggs, and soy helps muscles recover.
• Address underlying causes - Managing chronic illnesses can reduce associated muscle loss.

In summary, muscle loss is the wasting away of muscle tissue due to factors like aging, poor nutrition, and inactivity. Loss of muscle mass contributes to reduced strength, mobility issues, and metabolic changes. Staying physically active and eating properly can help conserve muscles as we age.
