Question 42 of 433
What is POTS?
The short answer
POTS is a chronic syndrome of symptoms on standing, with a sustained excessive heart-rate rise that is not explained by a significant fall in blood pressure or another cause.
In adults, the usual criterion includes a rise of at least 30 beats per minute within ten minutes upright; for adolescents aged 12–19 the threshold is at least 40. Symptoms usually have persisted for at least three months. Dehydration, anemia, medication effects, thyroid disease, and other explanations need consideration. A single jump on a watch does not establish POTS.
It often affects young women and can follow infection. Management is individualized: fluid and salt advice when appropriate, compression, symptom-directed medicines, and carefully tailored physical conditioning. Heart or kidney disease can change salt and fluid recommendations.
Some patients experience post-exertional symptom worsening, especially with overlapping post-viral illness. A fixed progression that ignores that response can be harmful. Begin with specialist-informed pacing and an activity plan that responds to the person’s tolerance rather than assuming everyone should push through.
