How does aging affect the risk of candidiasis in older adults according to the chapter?

Aging increases the risk of candidiasis in older adults due to a decrease in immune function. Factors such as diabetes, malnutrition, emotional stress, and the use of multiple medications that cause oral dryness also contribute to this increased risk.

Older adults are particularly susceptible to candidiasis because aging is associated with a decline in immune function. This risk is further heightened in individuals with diabetes, those who are malnourished, or those experiencing emotional stress. Additionally, many older adults take medications that can lead to oral dryness and reduced salivation, creating an environment conducive to Candida overgrowth. Poor oral hygiene and the use of dentures can also increase the likelihood of developing oral infections, including candidiasis.
