POTS (Post Orthostatic Tachycardia Syndrome)
POTS is a form of Dysautonomia aka Autonomic Dysfunction aka Autonomic Neuropathy.
This is a difficult disease to understand including in the medical field; more times than not, patients have to educate doctors. POTS also represents differently from patient to patient making things even more complicated.
So, what is POTS?
POTS is when you are unable to stand, come to standing from a lay down position or even sit for too long without feeling faint or fainting. Other symptoms include: dizziness, lightheadedness, fatigue, anxiety, a rapid heart rate and even blurred vision. This happens because the autonomic system is no longer working correctly and does not send the message to the brain that homeostasis (balance) is off in the body. Blood does not get to the heart properly, but rather pulls down. This usually causes a drop in blood pressure (an increase for some) and a super increase in heart rate. Usually 30bpm or higher than what it was before the change in position. This can make life very difficult for someone with POTS. It wears a person out to have their heart rate so high all the time and that in and of itself causes a myriad of symptoms such as: breathing difficulty, chest pain, migraines, and confusion just to name a few. If a person faints a lot they are at risk of falling and can cause serious injury to themselves.
Some people suffer from POTS for years before being diagnosed properly. A lot has to do with the lack of education in the medical field and it also has to do with the lack of proper testing facilities. Because of this patients can suffer for years before POTS is identified appropriately.
