>This woman is in her first tri-mester and experiencing extreme morning
sickness.  She's lost 10 pounds, can't hold anything down, and is really
becoming ill.  She has no other sickness. <
Of course this can be pathological and complicated and so on. But in my
experience, the most usual cause is well-intentioned change of diet to
include too much milk, or some other "good" food which this woman's body
says is no good for her. Cure: do a full dietary history, eliminate chief
suspect: food which she altered her relationship to since becoming
pregnant. (sometimes it's the same amount of food/pharmacologically active
food (coffee, tea, wine, chocolate, cheese)  and increased sensitivity to
it, but first time mothers usually follow arbitrary dietary advice that has
been developed by the dairy industry on the basis of calcium needs we now
know to be wrong, and make themselves ill if they were bottle fed as kids,
never drank plain milk but loved cheese, and all the other small indicators
that suggest tolerance is tricky.) If she can stop eating this food/foods
before her baby is 12 weeks (and its immune system starts developing ) she
may avoid sensitising the child and having a (take your pick of diagnosis
according to which industry rep has been by recently)
colicky/refluxy/lactose-intolerant  miserable baby. Good luck persuading
her.
