POTS (Postural Orthostatic Tachycardia Syndrome)
Postural Orthostatic Tachycardia Syndrome (POTS) is a condition where the body has difficulty adjusting to changes in position, especially when standing up. It causes an abnormal increase in heart rate—often more than 30 beats per minute within 10 minutes of standing—leading to symptoms like dizziness, lightheadedness, fatigue, and sometimes fainting. POTS results from issues with blood flow regulation, blood vessel constriction, or nerve signals involved in controlling blood pressure and heart rate. While its exact cause varies, it can significantly impact daily life but often improves over time with appropriate management and lifestyle adjustments.
