What is postural orthostatic tachycardia?
Whether you’re sitting, standing, or lying down, your blood is flowing at a steady rate. But when you change your posture, the ratio changes.
It can make you feel dizzy, especially when you lie down and stand up.
Postural tachycardia syndrome (POTS) is a very common disease.
When you stand up, most of your blood remains in the lower part of your body. This causes your heart to beat faster, trying to get blood into your brain and your heart rate increases 30 times or more in a minute.
When that happens, your blood pressure may drop.
Scientists do not know why, but women between the ages of 15 and 50 are more likely to get the disease.
When your heart is beating too fast and your blood pressure drops, other bodily functions lose their balance. You might:
- feel dizzy
- sweat a lot
- chest pain
The exact cause of its occurrence is unknown, but some diseases and conditions seem to make you more susceptible to pot disease. These risks include:
- autoimmune disease
- hepatitis C
