What is sarcopenia?

• A. A gradual loss of muscle mass, strength, and function.
• B. An acute inflammation of joints.
• C. A type of bone fracture.
• D. A condition of excessive fat mass.

Answer: (A)

Sarcopenia is the gradual loss of skeletal muscle mass, strength, and function that occurs with aging. As people get older, muscles tend to shrink and lose power, leading to difficulties with mobility, balance, and daily activities. It’s different from other conditions: arthritis is inflammation of joints; a bone fracture is a break in bone; excess fat mass describes obesity. Understanding sarcopenia helps explain why older adults may become frail and have a higher risk of falls, and it highlights the importance of activities like resistance training and adequate protein intake to maintain muscle health.
