Morning sickness is all about the hormones. That part isn’t surprising, but what’s newsworthy is that USC researchers say they’ve discovered exactly which hormone it is — and (potentially) what can be done about it.
The hormone is called GDF15, and it’s produced by the fetus; it surges in the first trimester.
“[T]he baby growing in the womb is producing a hormone at levels the mother is not used to. The more sensitive she is to this hormone, the sicker she will become. Knowing this gives us a clue as to how we might prevent this from happening.”
Some women are especially sensitive to GDF15 and can have morning sickness that requires hospitalization. (Looking at you, Catherine, Princess of Wales.) Other woman have a genetic blood disorder that gives them chronically high levels of GDF15 so they
