@ Micave: hoe is het met je site over POTS?
ik kwam een schrijven tegen over de vagus nervus: ik dacht misschien heeft het een relatie met POTS? (zal jij beter in kunnen schatten dan ik):

Vasovagal Reflex
~
Why do some IBS sufferers have these symptoms? The most likely explanation is the body’s own vasovagal reflex. The reflex stems from our vagus nerve, which is a nerve that travels from our brains to our colons, and contributes to a wide variety of physical functions, including swallowing, speaking, heart rate and digestion.

The vasovagal reflex is a sudden triggering of the vagus nerve. This may occur in response to a variety of factors, including:
~
~ Fear
~ Emotional stress
~ Gastrointestinal illness
~ Pain
~ Sight of blood
~ Standing for a long time
~ Standing up quickly
~ Trauma
~ or another one for you! (everyone is different on thresh holds)

The reflex results in an abrupt dropping of blood pressure and a sudden reduction in heart rate. At its worst, the reflex will result in fainting, as blood flow shifts away from the head and down into the legs. Fainting that is triggered by the vasovagal reflex is called vasovagal syncope.
