It’s Dysautonomia Awareness Month, but what actually is dysautonomia?
Well it’s not just one condition. It's an umbrella term for a group of conditions where the autonomic nervous system doesn't function as expected.
That's the part of your nervous system responsible for all the things your body is supposed to do automatically, like regulating your heart rate, blood pressure, digestion, body temperature, sweating, bladder function and even your pupils.
Dysfunction in the autonomic nervous system can cause a variety of symptoms including dizziness and fainting, abnormal heart rates and blood pressure, blood pooling, nausea, digestive problems, problems regulating your temperature, fatigue, sweating abnormalities and lots more.
Dysautonomia isn't rare either. Dysautonomia International estimates that more than 70 million people worldwide live with some form of it.
There are lots of different forms of dysautonomia. One is POTS, which is the type I have, where being upright causes an excessive increase in heart rate, alongside symptoms like dizziness, breathlessness, fatigue and sometimes fainting.
There’s also neurocardiogenic syncope, sometimes called vasovagal syncope, where the body can respond inappropriately to triggers, causing blood pressure and sometimes heart rate to drop, which can lead to fainting. And at the other end of the spectrum is Multiple System Atrophy, or MSA, a rare neurodegenerative condition that causes widespread autonomic dysfunction and can be fatal.
Dysautonomia can occur on its own, or secondary to other conditions, including diabetes, Parkinson's, lupus, MS, rheumatoid arthritis, EDS and more. It can also develop following infections. And since the COVID-19 pandemic, there’s been much more awareness of post-viral dysautonomia, because some people with Long COVID develop types of dysautonomia.
There isn't currently a cure for dysautonomia, but depending on the type and cause, symptoms can sometimes be managed with medication, lifestyle changes and treatment of underlying conditions.
