Dehydration is common in patients with dysphagia, with a prevalence between ~44% - 75% (Reber et al., 2019).

Other factors, such as aging and medical comorbidities, can further impact fluid intake.

Adequate hydration is important for sustaining kidney function, nutrient transport, homeostasis, waste elimination, and various other essential bodily functions (Reber et al., 2019).

Introducing thickened liquids can further exacerbate dehydration in those who are suspected to have dysphagia. Thickened liquids can lead to faster feelings of fullness and decreased fluid intake (Cicero, 2013). In fact, Vivanti et al. (2009) studied 25 patients on thickened liquids for 5 or more days, and found that none of them met their calculated hydration needs without supplemental enteral or paraenteral fluids.

I am working to develop a broader, research-backed focus on the impact of dysphagia and dysphagia intervention on hydration, nutrition, and quality of life. I am trying to promote a shift in focus beyond the "tunnel vision" of dysphagia and pneumonia risk, without allowing the pendulum to swing too far to the other side. I'd love to hear your thoughts on this!
