Autonomic Dysfunction and Postural Orthostatic Tachycardia Syndrome: What Every Frontline Clinician Needs to Know.

Autonomic dysfunction, particularly postural orthostatic tachycardia syndrome (POTS), is increasingly recognized in adolescents and young adults. Early recognition in primary care is critical, as these conditions can substantially affect functioning, school participation, quality of life, and health care utilization. This review provides practical, clinically relevant guidance for pediatric and family medicine clinicians, and emphasizes recognition, office-based assessment, initial management, and referral strategies. Key considerations include differentiating POTS from mimicking conditions, evaluating functional impact, and implementing structured lifestyle interventions. Medications are reserved for patients with significant functional impairment despite conservative management, with a focus on setting realistic expectations. Case vignettes illustrate common phenotypes and highlight practical approaches to individualized care. By providing clear frameworks for evaluation and management, primary care clinicians can reduce unnecessary specialty visits, improve patient outcomes, and facilitate coordinated care across multidisciplinary teams.
