What are some changes in older adults due to prolonged immobility?

• A. Decreased physical activity, changes in family and social structures, hormonal changes, and bone reabsorption.
• B. Weight loss but no bone changes.
• C. Increased muscle mass and improved balance.
• D. No significant changes.

Answer: (A)

When mobility is limited for a long time, multiple body systems are affected by disuse and aging. The most evident changes include less physical activity leading to deconditioning, social adjustments as dependence increases, hormonal shifts that influence bone and muscle health, and bone loss from lack of mechanical loading. Reduced activity causes muscles to weaken and waste away (atrophy), reducing strength and endurance and making movements even harder. Hormonal changes that come with aging—such as lower levels of estrogen or testosterone and shifts in other hormones—can accelerate loss of bone density and muscle mass, and disuse magnifies these effects. The result is bone resorption with a higher risk of fractures. Socially, prolonged immobility can alter family roles and routines, reduce participation in previously enjoyed activities, and increase isolation or depression. Other options don’t fit with what typically happens: weight loss may occur but isn’t the defining change and doesn’t emphasize bone loss; increased muscle mass and better balance contradict the effects of immobility; and claiming no significant changes ignores well-documented physical and social consequences.
