What they did: They reviewed dozens of POTS cases to explain causes, how to spot them, and what treatment options were available.

What they found:

• Standing up too fast makes your heart race by 30+ extra beats per minute without signi􀀂cantly dropping blood pressure.
• Three primary “types” of POTS: nerve-related, low blood volume, or overactive stress response.Why it matters for you:
• Lifestyle fixes: Raise the head of your bed by 4–6 inches, wear compression stockings, eat small, frequent meals, drink plenty of water, and add extra salt (if your doctor agrees).
• Medications: Fludrocortisone to boost blood volume; midodrine or pyridostigmine to tighten vessels; beta‑blockers to calm an overactive heart.
