What is POTS?
Postural Orthostatic Tachycardia Syndrome (POTS) is a condition that affects the autonomic nervous system. This part of the nervous system is in charge of “automatic” bodily functions like heart rate, blood pressure, and digestion. Many people with POTS discover they have it later in life, but it can happen in kids and teenagers, especially females.
Understanding the symptoms—both obvious and subtle—is crucial for parents navigating this complex condition.
The classic symptom of POTS is an excessive increase in heart rate when moving from lying down to standing, by about 40 beats per minute. This usually happens within 10 minutes of standing and results in palpitations or feeling lightheaded.
Is there anything that triggers POTS?
While doctors aren’t sure of the exact cause, it’s often associated with viral infections, autoimmune conditions, or periods of rapid growth like puberty. Doctors also believe emotional and physical trauma is a factor, like a stressful event or a concussion.
The obvious symptoms of POTS
The most recognizable signs of POTS in children include:
- Dizziness or lightheadedness: One of the most common complaints, especially after standing up, as the body struggles to regulate blood flow.
- Rapid heart rate: A noticeable and sustained increase in heart rate after standing.
- Fatigue: Severe, chronic (doesn’t go away) fatigue that doesn’t improve with rest and can interfere with daily activities.
