Postural Orthostatic Tachycardia Syndrome (POTS) is a condition that affects blood flow and heart rate. People with POTS experience a significant increase in heart rate when they stand up, which can lead to symptoms like dizziness, lightheadedness, and fatigue. This happens because their bodies struggle to regulate blood pressure and blood flow when changing positions. The exact cause of POTS can vary, but it often occurs after an illness or injury. Treatment may include lifestyle changes, such as increasing fluid and salt intake, and medications to help manage symptoms. Understanding POTS is essential for those affected to find effective ways to cope with this condition.
