Addressing Appetite Loss in Aging Adults

Understanding Appetite Loss in Aging Adults

Anorexia of Aging

Anorexia of aging is a term used to describe the common decline in appetite that occurs in many older adults. Approximately 1 in 3 seniors in Canada faces challenges in meeting their nutritional needs due to this phenomenon. It was first identified by researchers in the 1980s and can significantly impact the health and quality of life in aging populations. Factors such as physiological changes, psychological functioning, social environments, and medical conditions can influence appetite loss in seniors.

Studies estimate that between 15% and 30% of older individuals experience anorexia of aging, with higher rates reported among women, nursing home residents, and hospital patients [2].

Numerous physiological changes contribute to this condition, including decreased saliva production, diminished sense of taste and smell, and slower gastric emptying, which can lead to a decline in the joy of eating. Older adults may also experience constipation and dental issues, affecting their ability to consume food comfortably.

Factor	Description
Decreased Saliva Production	Reduces the ability to enjoy food.
Poor Dentition	Makes chewing difficult and unappealing.
Slow Gastric Emptying	Causes prolonged feelings of fullness.
Constipation	May lead to discomfort and reluctance to eat.

Impact of Long-term Poor Appetite

The long-term effects of decreased appetite can be detrimental. Reduced food intake may lead to nutritional deficiencies, impacting physical health and overall well-being. Those who struggle to maintain proper nutrition may experience significant weight loss, loss of muscle mass, weakened immune systems, and increased susceptibility to illnesses.

In addition to physical health implications, appetite loss can contribute to mental health challenges. Depression is common among older adults and is known to impair appetite, with reported rates ranging from 9% in community-dwelling older individuals to 27% in care home residents. Poor nutrition can further exacerbate depressive symptoms, creating a cycle that impacts quality of life.

Addressing appetite loss in aging adults requires awareness of these various factors and can benefit from ongoing support and intervention.
