As the population grows older, dysphagia is becoming an increasingly common condition and is believed to represent a significant healthcare problem. It has been estimated that 13–35 % of older people who live independently report dysphagic symptoms, with the vast majority failing to seek treatment (Roy et al., Ann Otol Rhinol Laryngol 116:858–865, 2007). Like other aspects of aging, presbyglutition is more associated with biological age than with chronological age. Age-related changes in swallowing can lead to impaired bolus control and transport, the slowing of pharyngeal swallow initiation, ineffective pharyngeal clearance, impaired cricopharyngeal opening, and reduced secondary esophageal peristalsis with strong consequences for independence and quality of life. The progression of biological age varies significantly from one person to the other, contributing to the heterogeneity of the aging process in each individual. In addition, there are problems that are not limited to the elderly but that seem to manifest themselves more in this population than in the young and affecting the swallowing process. These problems associated to comorbidities and certain types of medication may further complicate the swallowing process in old age.
