Hi,
I was diagnosed with severe IBS after near fatal campylobacter dose, which is the main cause of autonomic polyneuropathy. Many diseases can cause it also, like long covid for one.
Strictly campylobacter isn't the cause of the autonomic polyneuropathy, it is the body attacking the campylobacter which in doing so doesn't recognise the difference between that and the nerve meylin, so you start to have demeylination going on. I'm not sue why it doesn't stop once the campylobacter is gone, but would guess once learnt it keeps attacking the meylin, may be. It is not something I have looked into and may be should in case it can be stopped.
Cheers
