Postural Orthostatic Tachycardia Syndrome–Associated Dysphagia
Postural orthostatic tachycardia syndrome (POTS) is associated with patient-reported dysphagia symptoms. [1]
Evidence for an Association
A 2026 qualitative study using structured interviews found dysphagia impairment in a cohort of patients with POTS. [1] The mean Dysphagia Handicap Index (DHI) score reported in that cohort was 4.5, which the authors stated indicated significant swallowing impairment. [1] The study concluded that significant dysphagia symptoms are reported by patients with POTS, while noting that targeted characterization and pathophysiology studies are still needed. [1]
Symptom Frequency and Strength of Evidence
The available evidence consists of small, observational work with symptom reporting rather than population-based incidence estimates. [1] The same study reported dysphagia as “a common complaint” among patients with POTS, but it did not provide a quantified prevalence rate in the abstract. [1]
Potential Contribution of Comorbid Conditions
Comorbid hypermobile Ehlers-Danlos syndrome (EDS) was common in the POTS dysphagia cohort, occurring in 8 of 11 participants, which may contribute to swallowing complaints in some patients. [1] Ehlers-Danlos–related laryngological complaints have been described in the literature with frequent comorbidities including POTS and reflux disease. [2]
Clinical Implication
POTS should be considered in the differential diagnosis for patients reporting dysphagia who also meet criteria for POTS, given published reports of dysphagia impairment in this population. [1]
Key Limitations
Causal inference cannot be confirmed from current evidence, because published data are based on a small qualitative cohort and do not establish mechanism or directionality. [1]
Practical Next Steps for Evaluation
Dysphagia symptoms in patients with POTS still warrant standard dysphagia evaluation to exclude other common causes of swallowing difficulty, including structural and gastrointestinal etiologies, because current POTS-specific evidence does not establish etiology. [1]
