Have you ever been so sick in pregnancy that you couldn't keep water down, lost weight, or ended up in hospital wondering how your body was supposed to sustain a baby when it couldn't sustain itself? If that's your story, or the story of someone you love, you've probably also been told at some point that it was stress, anxiety, or something you just needed to push through.

It wasn't. And the science has finally caught up with what HG patients have been saying for decades.

In this episode, Dr Renee White unpacks the genetic and hormonal research that proved once and for all that hyperemesis gravidarum isn't psychological. It lives in a gene, it runs through a receptor, and it has nothing to do with how much you wanted your pregnancy.

You'll Hear About:

• Why HG is a distinct condition from morning sickness
• How a placental hormone called GDF15 drives severe nausea
• Why your baseline levels before pregnancy predict your risk
• What the beta thalassemia finding revealed about sensitivity
• How pre-pregnancy desensitisation could prevent HG entirely

Your body wasn't failing you. It was responding to a hormonal contrast it hadn't been prepared for, and now researchers know exactly why. The science sees you, and it's moving fast.

If someone in your life has been through HG, share this episode with them. It might be the first time the biology's been explained in a way that finally makes sense. And subscribe so you don't miss an episode of The Science of Motherhood.
