Chronic dizziness that becomes worse when standing may be more than dehydration or stress. One possible cause is postural orthostatic tachycardia syndrome (POTS), a condition that can be assessed with standing vital-sign measurements or a tilt-table test.
📌 Key Summary
Dizziness with standing and a racing pulse may justify asking about POTS evaluation.
• Main cause: Autonomic nervous system dysfunction can affect heart-rate control.
• Management: Track symptoms, hydrate regularly, and seek individualized medical advice.
• Warning signs: Fainting, chest pain, or stroke-like symptoms need urgent care.
POTS is a form of dysautonomia, meaning the automatic functions that regulate heart rate, blood pressure, digestion, and temperature do not respond normally. When a person stands, blood may pool in the lower body and the heart rate can rise excessively to compensate.
Symptoms may include lightheadedness, brain fog, fatigue, palpitations, nausea, shakiness, and exercise intolerance. They often intensify during prolonged standing, hot weather, illness, menstrual changes, or after viral infections.
Dizziness also has many other causes, including inner-ear disorders, vestibular migraine, anemia, medication effects, low blood pressure, thyroid disorders, and anxiety. A careful assessment matters because the right treatment depends on the underlying cause.
Before an appointment, record when dizziness occurs, whether you were sitting or standing, your pulse if available, fluid intake, medications, and related symptoms. This pattern can help a clinician distinguish autonomic symptoms from vestibular or cardiovascular causes.
📋 Daily Practical Checklist
☑ Drink fluids consistently unless a clinician has restricted them.
☑ Choose gradual, tolerable movement and avoid pushing through near-fainting.
Some people with POTS benefit from tailored fluid, sodium, compression, exercise, or medication plans. These approaches should be personalized, particularly for anyone with high blood pressure, kidney disease, heart disease, or an eating disorder.
⚠️ Please Check This
Seek emergency care for new chest pain, severe shortness of breath, fainting with injury, one-sided weakness, trouble speaking, a severe sudden headache, or a persistent irregular heartbeat. Do not self-diagnose POTS based on a single pulse reading.
What test is used to check for POTS?
Clinicians may measure heart rate and blood pressure while lying down and standing, or use a tilt-table test. In adults, POTS is considered when heart rate rises by at least 30 beats per minute within 10 minutes of standing without a major blood-pressure drop.
Can POTS feel like anxiety?
Yes. Palpitations, breathlessness, shaking, and lightheadedness can overlap with anxiety symptoms. Both conditions can coexist, so persistent symptoms deserve a physical evaluation rather than assumptions.
Should I increase salt and water if I feel dizzy?
Do not substantially increase salt without medical advice, especially with high blood pressure, kidney disease, or heart disease. Regular hydration may help some people, but the cause of dizziness should be assessed first.
