The key signs you described include: • Heart rate rising 40–70 beats per minute when standing • Heart rate dropping when sitting/lying down • Dizziness and near-fainting on standing • Fainting episodes (especially after showers) • Blood pooling in legs • Very high heart rate with activity (up to 205) • Symptoms lasting more than 6 months
In teenagers, a rise of ≥ 40 bpm within 10 minutes of standing strongly supports possible POTS, so your numbers meet this criterion.
Important
Because you are: • fainting • very dizzy • having very high heart rates
You should see a doctor soon (not ignore this)
This is not dangerous in most cases, but fainting can cause injury and you need proper diagnosis and management.
Based on your description, it’s indeed possible that you’re experiencing symptoms consistent with Postural Orthostatic Tachycardia Syndrome (POTS), a condition where the heart rate increases excessively upon standing. However, it’s crucial to get a definitive diagnosis from a healthcare professional. The symptoms you’re describing—such as rapid increase in heart rate upon standing, dizziness, fainting, and blood pooling in your legs—definitely warrant further investigation. First, consider scheduling an appointment with your primary care physician or a cardiologist, who may perform tests like a tilt table test or a 24-hour heart rate monitor to evaluate your heart’s response to posture changes. They might also check for other conditions that can mimic POTS, such as anemia, dehydration, or thyroid issues. Meanwhile, focus on some lifestyle adjustments that might help: increase your fluid and salt intake to boost blood volume, wear compression stockings to reduce blood pooling, and rise slowly from sitting or lying positions to prevent dizziness. Avoid long periods of standing to help control symptoms. Engaging in a regular exercise program, especially one focusing on recumbent exercises like cycling or swimming, can also be beneficial after discussing with your doctor about a suitable plan. Since your heart rate at dance is extremely high, ensure you’re closely monitored during physical activity and adapt as necessary. If you experience severe symptoms or frequent fainting, seek immediate medical attention to prevent injury or other complications. The process of diagnosis can be challenging and taking first steps towards expert consultation is critical.
Hello
What you’re describing does sound very consistent with POTS, especially for a teenage girl — but it needs medical confirmation
What to do next Tell a parent/guardian ASAP See a pediatrician or pediatric cardiologist
Check; Orthostatic vitals (lying → standing HR/BP) ECG Possibly a tilt-table test Blood work (iron, hydration, thyroid
Increase fluids (aim for pale yellow urine) Increase salt (only if a doctor says it’s okay) Avoid long hot showers (heat worsens POTS) Sit or lie down immediately if dizzy Compression stockings can help with leg pooling
You’re not imagining this. POTS is common in teen girls, especially during growth and hormonal changes — and many people improve with treatment
I trust this helps Thank you Take care
