Body Systems, Aging, and Meeting Physical, Emotional, and Developmental Needs

  • Normal aging changes include thinner skin, reduced fat padding, lower thirst sensation, decreased renal function, and slower healing.

  • Presbyopia, cataracts, and high-frequency hearing loss are common age-related sensory changes.

  • Older adults have a blunted thirst response and lower total body water, so dehydration can occur without thirst.

  • Thermoregulation declines with age, raising the risk of hypothermia and heat stroke.

  • Erikson's final psychosocial stage is integrity versus despair, in which older adults review their life and seek meaning and acceptance.

  • Bone density and muscle mass decline with age, increasing the risk of falls and fractures.

  • Reduced saliva production and slower gastric motility contribute to dry mouth and constipation in older adults.

  • Range-of-motion and weight-bearing activity help preserve joint function and slow contractures and bone loss.
