Does simply standing up make your heart race?
If you experience rapid heart rate, dizziness, lightheadedness, heart palpitations, brain fog, fatigue, tunnel vision, weakness, or feeling like you might faint, you may be dealing with symptoms commonly associated with POTS (Postural Orthostatic Tachycardia Syndrome) or dysautonomia.
And no, these symptoms aren't always “just anxiety.”
With POTS and other forms of autonomic dysfunction, the body can struggle to properly regulate blood flow, circulation, blood pressure, heart rate, and the nervous system when you move from sitting or lying down to standing.
As your body tries to compensate, your heart rate may increase, leaving you feeling dizzy, exhausted, shaky, or like standing itself takes all your energy.
Other factors that may contribute to worsening POTS symptoms and orthostatic intolerance include:
• blood sugar instability
• nervous system dysregulation
• dehydration and electrolyte imbalance
• poor vascular tone
• metabolic dysfunction and other underlying factors
If your blood tests look “normal” but you're still struggling with POTS, dizziness, tachycardia, fatigue, or fainting symptoms, it may be worth taking a deeper look at what could be contributing to the pattern.
