Review Questions

• What physiological factors contribute to anorexia of aging in older adults?
  • Physiological factors contributing to anorexia of aging include changes in taste and smell, which may reduce the enjoyment of food. Additionally, dental issues such as missing teeth or ill-fitting dentures can make chewing difficult. Gastrointestinal changes like decreased gastric emptying can also lead to feelings of fullness after consuming small amounts of food, further limiting intake.
• How do psychological and social factors interact with physiological changes to affect nutritional needs in older adults experiencing anorexia of aging?
  • Psychological factors such as depression or anxiety can greatly influence appetite and motivation to eat. Social factors, including loneliness or lack of companionship during meals, can also diminish the desire to eat. Together with physiological changes like altered taste and digestive issues, these factors create a complex interplay that challenges the ability to maintain adequate nutrition in older adults.
• Evaluate the long-term implications of untreated anorexia of aging on the overall health and well-being of older adults.
  • Untreated anorexia of aging can have serious long-term implications for older adults, leading to significant weight loss and malnutrition. This decline in nutritional status increases the risk for various health complications such as frailty, weakened immune function, and greater susceptibility to infections. Furthermore, the resultant muscle loss from inadequate protein intake can exacerbate sarcopenia, leading to decreased mobility and independence. Addressing this condition is essential for enhancing longevity and quality of life among the elderly population.
