POTS Syndrome Symptoms Quiz
These questions help you organize chronic symptoms that seem linked to standing or being upright, such as lightheadedness, a racing heart, fatigue, shakiness, or brain fog. POTS is a clinical diagnosis based on a sustained heart-rate rise with standing, ongoing orthostatic symptoms, and exclusion of other causes, so your results are meant to guide a conversation with a healthcare professional—not diagnose you.

Frequently Asked Questions
Common questions about this quiz, what it covers, and what your results mean.
This is for health education only and is not a diagnosis. Do not perform unsafe home testing or force yourself to stand if you feel faint, weak, or unwell. Seek urgent medical help for fainting with injury, chest pain, severe shortness of breath, or new neurologic symptoms.
POTS stands for postural orthostatic tachycardia syndrome. It is a condition where standing leads to chronic orthostatic symptoms and a sustained rise in heart rate without a major drop in blood pressure, after other causes are considered.
Symptoms that get worse when you stand and improve when you sit or lie down can point to orthostatic intolerance. This pattern helps a clinician decide what questions, vital signs, and tests may be useful.
POTS can have different contributing factors, and the cause is not always clear. Clinicians also look for conditions that can mimic POTS-like symptoms, such as anemia, dehydration, fever, thyroid problems, and medication effects.
No. Anxiety can cause a racing heart or dizziness, but POTS is defined by a posture-related heart-rate response and chronic orthostatic symptoms. A clinician can help sort out overlapping symptoms.
Yes. Dehydration can cause dizziness, weakness, fast heartbeat, and feeling worse when standing. That is one reason clinicians check for common explanations before diagnosing POTS.
Common symptoms include lightheadedness, a racing or pounding heart after standing, weakness, shakiness, fatigue, brain fog, nausea, headache, and symptoms that improve when lying down.
POTS is diagnosed by a healthcare professional using symptom history and orthostatic vital signs or formal testing. It requires chronic orthostatic symptoms, a sustained heart-rate rise with standing, and no significant orthostatic hypotension, while considering other causes.
Do not perform unsafe home testing or force yourself to stand if you feel faint. If you are concerned about POTS, track symptoms and discuss safe evaluation with a healthcare professional.
Blood tests do not diagnose POTS on their own, but clinicians may use them to look for overlapping causes. These may include a complete blood count, metabolic panel, thyroid testing, iron studies, or other tests based on your history.
Seek urgent medical help for fainting with injury, chest pain, severe shortness of breath, or new neurologic symptoms. These symptoms need immediate evaluation and should not wait for routine follow-up.
Some people with POTS or orthostatic intolerance faint, while others mainly feel like they might faint. Fainting, especially if it causes injury or happens with chest pain or severe shortness of breath, should be evaluated promptly.
Brain fog can occur with POTS, but it is not specific to POTS. Sleep problems, stress, low iron, thyroid issues, medications, and other conditions can also affect focus and memory.
Ongoing orthostatic symptoms can interfere with school, work, exercise, and daily activities. Evaluation matters because treatable causes may be present and because a clinician can suggest safe management steps.
Improvement varies widely and depends on the person and the cause of symptoms. Some people improve with a care plan over weeks to months, while others need longer follow-up and adjustments.
Bring notes about when symptoms happen, how long they last, what position you are in, what improves them, possible triggers, fainting episodes, recent illness, medications or supplements, and any prior test results.
