Not sure what the last bit here means.

Gonneke, I believe that this could indeed be caused by hormones.
Kirsten Uvnas-Moberg spoke at length about the actions of oxytocin
and related hormones at the 1998 ALCA Conference. I have only
listened to the tapes, as I couldn't attend, but this rang a bell
with some things she said. I hope my notes are reasonably accurate
here.

Oxytocin, both during pregnancy and lactation causes relaxation of
the stomach, and closes off the pyloric sphincter so that the gut
becomes more efficient and absorbs more of the available food. It is
also associated with CCK and I think some other gut hormones which
tend to cause nausea. So this possibly explains morning sickness as
well.

Also, eating stimulates CCK release and subsequently oxytocin as well.

 From a practical point of view, it is often suggested that the mother
eat something before breastfeeding, if she often feels nauseous at
the let-down. And that mothers with these experiences usually find
that the effect diminishes with time, so after the first few weeks
they no longer feel nauseous.

Oh, and another snippet about oxytocin and its synthetic versions -
my understanding is that the synthetic versions do not cross the
blood-brain barrier, so do not have the psychological effects of
natural oxytocin. Therefore if synthetic oxytocin is given, it
suppresses the release of natural oxytocin, therefore you don't get
as much of the psychological effects of bonding, etc. I thought this
may relate to the discussion about oxytocin receptors.
