These are definately related - I ate like a horse before my PN - now with heridiatary body wide PN and autonomic neruopathy live on meds and liquids only to try to digest the liquids and maintain some weight - I have severe GP - most doctors dont have a clue what to do about it... if your lucky you neuro can diagnosis it but you have to be treated by a GI doctor who is a motility specialist if its bad (and they can be tough to find but be persistent) - hang in there....
