# Many Women Misdiagnosed With Anxiety Actually Have POTS, Researchers Find
Women reporting anxiety symptoms often receive a psychiatric diagnosis when their condition actually stems from a cardiovascular disorder. Postural Orthostatic Tachycardia Syndrome, or POTS, produces panic-like symptoms that closely mimic anxiety disorders, leading to widespread misdiagnosis in female patients.
POTS causes the heart rate to spike abnormally when moving from lying or sitting to standing. The condition triggers dizziness, chest pain, shortness of breath, trembling, and a racing heartbeat. These physical responses feel indistinguishable from panic attacks to patients experiencing them, but the root cause is neurological dysfunction affecting blood vessel control rather than a psychiatric condition.
The distinction matters enormously for treatment. A woman diagnosed with anxiety receives cognitive behavioral therapy, medication like SSRIs, or both. A woman with POTS requires entirely different interventions: salt loading, fluid intake increases, compression garments, exercise reconditioning, and in some cases beta-blockers or other blood pressure medications that actually address the underlying cardiovascular dysregulation.
POTS primarily affects women between ages 15 and 50, though the reasons remain unclear. Estimates suggest 500,000 to 3 million Americans have the condition, yet many go undiagnosed for years. Studies indicate that patients with POTS spend an average of five years seeking proper diagnosis, visiting multiple doctors before receiving correct identification.
The confusion between POTS and anxiety stems from overlapping symptom presentation. Both conditions produce heart palpitations, trembling, sweating, and fear responses. A woman lying on an exam table might feel perfectly calm, then stand up and experience a racing heart. She interprets this as anxiety. Her doctor, seeing no obvious trigger, reinforces that interpretation by diagnosing generalized anxiety disorder or panic disorder.
A tilt table test reveals the truth. During this diagnostic procedure, a patient lies flat while a machine monitors heart rate and blood pressure. The table gradually tilts upward to simulate standing. A POTS diagnosis requires a heart rate increase of at least 30 beats per minute within ten minutes of tilting, without a corresponding drop in blood pressure. Patients with pure anxiety show normal cardiovascular responses during the test.
Women should request tilt table testing if they experience heart palpitations, dizziness, or chest discomfort triggered by position changes, especially if anxiety medications fail to resolve symptoms. These red flags suggest cardiovascular dysfunction rather than psychiatric illness.
The treatment gap extends beyond misdiagnosis. A woman given SSRIs for POTS-related symptoms may experience worsening dizziness or heart rate instability as a side effect. She then receives additional psychiatric medication to address the new symptoms, creating a cascade of inappropriate interventions. Meanwhile, the actual condition progresses untreated.
Recovery from POTS requires a structured approach. Increasing daily salt and fluid intake immediately helps by expanding blood volume. Compression socks or full-body compression garments reduce blood pooling in the legs when standing. Gradual exercise reconditioning, particularly recumbent cycling or swimming, strengthens the cardiovascular system without triggering excessive heart rate responses.
Recognizing POTS as distinct from anxiety allows proper treatment to begin. Women experiencing position-triggered cardiac symptoms should push for tilt table testing rather than accepting an anxiety diagnosis without investigation.
