Evolutionary Medicine and Women’s Health

For many women, “morning sickness” is one of the first signals of pregnancy. Regarding this symptom as a problem, conventional medicine has invested considerable effort in the search for a safe drug to diminish the nausea that so frequently accompanies the first trimester of pregnancy. But what if this admittedly uncomfortable and inconvenient symptom is not a defect, but rather a natural defense mechanism?

“From an evolutionary perspective, morning sickness leads women to avoid the consumption of foods that may be especially toxic to the developing fetus,” said anthropologist Wenda Trevathan, who also trained as a midwife. “Up to a point, the nausea serves a purpose: it was naturally selected because it protected the embryos. So unless the morning sickness is extreme, evolutionary medicine would encourage women to tolerate the nausea rather than treat it with something that may harm the fetus.”
