Kate also suffered from hyperemesis gravidarum (HG) while pregnant with Princess Charlotte in 2014 and Prince Louis in 2018, but stayed at home in Kensington Palace. The condition meant that she was forced to announce both pregnancies early, before the normal 12-week mark, and she described the experience as ‘utterly rotten.’ Hyperemesis gravidarum can be so severe that sufferers vomit up to 30 times per day, resulting in dehydration
Speaking on the Happy Mum, Happy Baby podcast, in 2020, Kate said: “I was really sick. I wasn’t eating the things I should be eating and yet the body was still able to take all the goodness from my body and to grow new life, which I think is fascinating.”
