Postural orthostatic tachycardia syndrome (POTS)
POTS: An overview
Standing up is something most of us take for granted; we’ve been doing it since childhood. Our bodies automatically adjust to the pull of gravity by increasing vascular tone, heart rate and cardiac output. Blood vessels contract, heart rates increase and our systolic blood pressure remains the same or decreases slightly while diastolic pressure increases slightly (Brunner & Suddarth, 2000, p. 546). Our bodies operate in perfect homeostasis and we stand up with little effort.
However, the simple act of standing up can be a challenge for some people. There are disorders that affect the body’s ability to appropriately adjust to the pull of gravity. When the body cannot effectively adjust to upright posture, a person is said to have orthostatic intolerance. Postural orthostatic tachycardia syndrome (POTS) is a disorder characterized by orthostatic intolerance.
Postural orthostatic tachycardia syndrome is defined by excessive heart rate increments upon upright posture. A person with POTS will experience heart rates that increase 30 beats or more per minute upon standing and/or increase to 120 beats or more per minute upon standing (Grubb, 2000). These exaggerated heart rate increases usually occur within 10 minutes of rising.
While the hallmark of POTS is an excessive heart rate increment upon standing, patients often exhibit numerous symptoms of autonomic nervous system dysregulation, and research by the Mayo Clinic suggests POTS is a limited autonomic neuropathy (Thieben, Sandroni, Sletten, Benrud-Larson, Fealey, Vernino, Lennon, Shen & Low, 2007). Many POTS symptoms seem to be caused by an imbalance of the autonomic nervous system’s control over blood flow. It is the autonomic nervous system (ANS) that regulates the needed adjustments in vascular tone, heart rate and blood pressure upon standing. Some of the messages coming from the autonomic nervous system tell the blood vessels to relax or tighten. In people with POTS, the system seems to be out of balance and blood is not going to the right place at the right time to do what the body needs (Fischer, 2007).
I don’t care what kind of blog I have I will blog this no matter what.
"Craving sensation: feeling unreal" was such a huge part of the beginning of my relapse. I was convinced that people in front of me didn’t even exist and I kept touching things and trying to feel sensation. I’m reblogging because I know that that was so horrifying for me and I never want anyone else to go through it.
