Autonomic nervous system dysfunction is also known as
Dysautonomia.
Basically you need to understand what is autonomic/sympathetic
nervous system. This kind of nervous system controls body activity
which your brain has no control of. Such as sweating, heart beat,
vasoconstriction and dilation due to beta-adrenergic effect.
Therefore Dysautonomia means your body has a problem controlling
the above samples of body activity.
Symptoms include irregular heart beat, frequent
sweating(diaphoresis) and excess fatigue. Loss of muscle strength
might be one of the symptoms. The symptoms associating with this
disorder is dependent on individual.
You will be categorised as C9L9 or E9L9. Apart from it, you will
be referred to a neurology for further diagnosis. Tilt test is
inaccurate to conclude.
I believe your condition is very mild and shouldnt require
medication's intervention.
Should there be a need to, medicines such as fludrocortisone, midodrine, ephedrine and SSRI(selective-serotonin reuptake inhibitor) can
make symptoms milder.
There's no treatment for this. Cause of this is still unknown,
just like Marfan Syndrome.
wow, are u a doctor ?
