[AlternativeAnswers] any suggestions

I am working with a girl who loses consciousness on occasion, when she
does she vomits a clear gel. She has had tests run and no one can
figure out what is wrong.
Her medical history: raped at 3yrs of age, surgeries for ingrenal
hernia at ages 3 and 16. When she was 16 they twisted and sewed the
muscle so it could not tear again. Tonsilectomy at age 21, had a baby
at age 25. After every surgery and giving birth to the baby she got
severly dizzy and faint and lost consciousness when they got her out of
bed. The doctors just sent her home in that condition every time and
let her family deal with the consciousness issue which lasted for a few
days. She said she couldn't eat real sweet things as a kid because she
would wake up at night with a stomach ache and dizzy. Tests for
diabetes comes back negative.
Doctors don't seem concerned because her blood work comes back good.
She is 40 now and still deals with all the same issues. Her son has had
some of the dizzy spells and almost lost consciousness. They have run
tests on him and have found nothing. They said his was possible
dehydration so he should drink more water when he feels like that.
I am puzzled, any ideas?
