Nausea and Vomiting In Pregnancy
I get nauseated just thinking about how sick I was my first three months of pregnancy. I keep hearing how morning sickness is a good thing even though it doesn't feel that way.See also: www.getpregnantover40.com for more on pregnancy and fertility over 40 and preventing miscarriage
This article talks about the evolutionary connection with pregnancy nausea:
From the article:
The idea is that a pregnant woman afflicted with nausea and vomiting will be unlikely to eat certain foods that may be damaging to her fetus when its major organ systems are developing. Organ development takes place during the first three months of pregnancy, which is when morning sickness is most prominent. ''There is an obvious -- indeed striking -- correspondence between the sensitive periods in embryonic organogenesis and the peak occurrence of N.V.P.,'' the scientists wrote.
At this time, too, the Cornell biologists noted, a pregnant woman's immune system is naturally suppressed to keep her from rejecting the fetus as a foreign tissue. But immune suppression renders her more susceptible to food-borne parasites and microorganisms and the toxins they produce, so N.V.P. would protect her, too.
