Postural Orthostatic Tachycardia Syndrome (POTS) Explained
Postural orthostatic tachycardia syndrome (POTS) is a condition that affects your body’s regulation of blood pressure and heart rate. When you stand up from a sitting or lying down position, your blood pressure normally increases slightly to keep blood flowing to your brain. In people with POTS, this increase doesn’t happen effectively, causing symptoms like:
- Lightheadedness or dizziness, especially when standing up
- Fast heart rate (tachycardia), typically over 100 beats per minute while standing
- Fatigue
- Nausea
- Blurred vision
- Headache
- Palpitations (feeling your heartbeat)
- Difficulty concentrating
Causes:
The exact cause of POTS is unknown, but it is thought to be related to:
- Problems with the autonomic nervous system: This system controls involuntary functions like heart rate and blood pressure.
- Dehydration: Not drinking enough fluids can contribute to POTS symptoms.
- Certain medications: Some medications, like blood pressure medications, can worsen POTS symptoms.
- Medical conditions: POTS can sometimes occur after an illness or surgery.
Diagnosis:
There is no single test to diagnose POTS. Doctors typically diagnose it based on your symptoms and a physical examination. They may also order tests to rule out other conditions with similar symptoms.
Treatment:
There is no cure for POTS, but there are treatments that can help manage symptoms, such as:
- Increased fluid intake: Drinking plenty of fluids helps maintain blood volume and reduce dizziness.
- Increased salt intake: Salt can help your body retain fluids and improve blood pressure.
- Compression stockings: These stockings can help improve blood flow in your legs.
- Medication: Medications like beta-blockers or other drugs can help regulate heart rate and blood pressure.
- Exercise: Specific exercise programs can help improve symptoms and overall health.
Living with POTS:
While POTS can be challenging, many people can manage their symptoms with treatment and lifestyle changes. It’s important to work with your doctor to develop a personalized management plan that works for you.
