presbyphagia

Presbyphagia is the term used to describe the age-related changes in swallowing function that can occur as individuals get older. It is not a disease but rather a natural consequence of the aging process affecting the muscles and nerves involved in deglutition, the act of swallowing. These changes can lead to a variety of symptoms, though they are not always apparent or severe.

Commonly observed changes include a longer duration for the oral phase of swallowing, meaning it takes more time to prepare food or liquid for swallowing. The pharyngeal phase, where the bolus is propelled down the throat, may also become less efficient. This can manifest as a feeling of food sticking in the throat, a delayed swallow reflex, or coughing and choking during or after meals. Changes in taste and smell can also influence appetite and food enjoyment, potentially leading to reduced intake.

While presbyphagia is a normal part of aging, it's important to distinguish it from dysphagia, which is a more significant and pathological impairment of swallowing. However, presbyphagia can sometimes increase the risk or severity of dysphagia, especially in individuals with other underlying health conditions. Maintaining good oral hygiene, staying hydrated, and making appropriate dietary modifications can help manage the effects of presbyphagia and ensure safe and efficient swallowing.
