Postural orthostatic tachycardia syndrome is a condition where the heart rate rises sharply when a person stands. This happens because blood shifts away from the upper body and the body reacts by increasing heart rate. People experience dizziness and tiredness. Early steps help guide care.

Blood pools in the lower body when standing, so the heart races to maintain circulation. Illness, dehydration, or prolonged inactivity can contribute. Many people notice symptoms during growth or after infection.
Dizziness, rapid heartbeat, fainting, nausea, and brain fog are common. Symptoms improve when lying down. Fatigue often persists throughout the day.
Diagnosis includes measuring heart rate and blood pressure while lying down and standing. Doctors look for a significant rise in heart rate without a drop in blood pressure. History helps identify triggers. Tests rule out thyroid, heart, or electrolyte problems. Patterns guide next steps.
PoTS limits standing, walking, and chores that require upright posture. People often take breaks to avoid dizziness. Concentration drops when symptoms flare. Heat, stress, and dehydration worsen daily function. Many pace activities to manage energy.
Care focuses on hydration, increased salt intake when appropriate, and gradual physical conditioning. Compression garments help maintain circulation. Medications may support heart rate control. Daily routines are adjusted to reduce symptom flares. Follow-up visits guide long-term planning.
If something feels off or your symptoms stick around longer than expected, it's a good idea to get checked. Sudden changes, discomfort that doesn't improve, or anything that affects your daily routine deserve attention. A doctor can help figure out what's going on and guide you on the right next steps.
