Swollen vulva: no epidemic; it's just one of the classic symptoms of
adrenal neoplasia.  Ferrets don't need to have all of the symptoms to
be considered to be likely adrenal neoplasia surgery candidates.
 
To read the symptoms just check the back mails on the topic "adrenal
symptoms" or something similar in the Ferret Mailing List Archives.  The
address of the FML Archives is in the header of every issue of the FML
so it is always easy to find.  In addition, check the FHL Archives at
http://fhl.sonic-weasel.org/, the FHL at
http://www.smartgroups.com/groups/ferrethealth and the links in the
Critical References List at http://www.ferretcongress.org .
 
ALL of those resources are useful since among them they tackle most
ferret health problems.  Information is readily available for pretty
much most ferret health problems.
 
Seizures: Sounds like classic insulinoma.
 
The vet will draw blood from the external jugular (They mind the alcohol
swab more than the stick if a treat that makes them hold their heads up
high is given at the same time), then test it for blood glucose level.
Usually, surgery is the approach used.  When surgery isn't possible Pred,
or Pred and Diazoxide are given.  See resources mentioned above.
 
The ferret does NOT have to be having a seizure at the time of the vet
appointment.  Ferrets aren't cars, a person doesn't wait for the squeak
to reappear.
 
Eating: Your little one will eat more slowly when she teaches herself
that she is causing her own gagging, or when she doesn't feel that she
has to compete for food if that is the case in your household.  If there
are multiple ferrets try putting out multiple food bowls in different
areas.
 
Addition to yesterday's ECE note: DO consider other possible causes of
runs and have fecal testing done.  Also, consider that your bag of food
may be turning bad.  Look for stashes of food that is going bad, too, and
for eating of non-food items.  Consider that perhaps too many treats may
be given, or that a treat item may disagree with the belly.  The list
goes on, but those are some common causes of intermittent gastric upset.
When it's more serious things like IBD wind up considered.  Go to the
International Ferret Congress URL given above and pull up the AFIP site
of Dr. Bruce Williams and read up there.
 
As usual, I am not a vet, just someone who has had ferrets in the family
for 20 years (21 in 3 months) and has been involved in assorted ferret
health projects for most of that time.
