What is sarcopenia?

• A. Loss of bone density
• B. Loss of muscle mass and strength
• C. Increase in fat mass
• D. Decreased appetite

Answer: (B)

Sarcopenia is an age-related decline in skeletal muscle mass and function, meaning muscles become smaller and weaker, which leads to reduced strength and physical performance. This combination explains why it most accurately describes the condition, affecting mobility and independence in older adults. The other options describe different issues: loss of bone density refers to osteoporosis, an increase in fat mass is adiposity, and decreased appetite points to anorexia—none of which define sarcopenia. Management centers on resistance-type exercise and adequate protein intake to help preserve or rebuild muscle mass and strength.
