In the thick of it: A commentary on the strength of evidence for thickened fluids

The efficacy of thickened fluids for individuals with dysphagia has come under increasing scrutiny among healthcare professionals. This commentary provides a critical appraisal of the research evidence and presents a balanced argument on the benefits and limitations of thickened fluids in dysphagia management. By doing so, we aim to engage the readership to think critically about this controversial topic and make informed, patient-centered decisions regarding the use of thickened fluids in dysphagia management.

We argue that, while the research evidence for the use of thickened fluids in dysphagia management continues to grow, perhaps our problem lies in trying to find one pure answer-to thicken or not to thicken. We encourage clinicians to move past arguments about the controversies of thickened fluids and, rather, use the current evidence base, including research evidence, clinical expertise, and patient preferences to support individuals with dysphagia to make informed choices about their oral intake, in the short and long term.
