7 Celebs Who've Had Hyperemesis Gravidarum — Because It's No Walk In The Park

The Duchess of Cambridge was hospitalized for HG in 2012, when she was pregnant with Prince George, according to Forbes . Unfortunately, this royal mama has struggled with the condition during her subsequent two pregnancies as well. In fact, HG was included in the official pregnancy announcement from Kensington Palace when the Duchess was expecting Prince Louis. "As with her previous two pregnancies, The Duchess is suffering from Hyperemesis Gravidarum," the palace's official Twitter account tweeted in September 2017. "Her Royal Highness will no longer carry out her planned engagement at the Hornsey Road Children's Centre in London today. The Duchess is being cared for at Kensington Palace."

The former Will & Grace star had such severe morning sickness during her pregnancy, that she wound of dehydrated. "I had to spend time in bed, resting and having intravenous fluids," she said, per Latina.

It's no secret that Kim Kardashian has had particularly difficult pregnancies with her first two children. Placenta accreta nearly caused her to bleed to death after giving birth, for one. Something else she dealt with was preeclampsia, as Parents noted. And to top it all off, she also struggled with debilitating vomiting and nausea. "To be honest, I’ve had really bad morning sickness, day sickness, night sickness — I can barely get out of bed," Kardashian told Us Weekly when she was pregnant with Saint in 2015. "It’s a very different type of pregnancy from my first one, but I'm so grateful to be pregnant when we didn't even think it was going to happen for us [so] I don't care how sick I am."

Like her sister, Kourtney Kardashian also coped with all-day sickness during her pregnancies — although she never specifically used the term "HG." "I had a lot more morning sickness than last time. I was also more tired," she told Parents while she was pregnant with her second child, Penelope.

"She is having morning sickness," Khloé Kardashian told E! News of her sister. "But it's not even in the morning. It happens any time, apparently."

"I vomit a good dozen times a day it's, like, bad. I vomited before coming out here," the American Idol alumna told Ellen DeGeneres when she was pregnant with her daughter, River Rose, Us Weekly reported. "I'm not even kidding, it's so bad. It's so bad. It's, like, so gross." Clarkson added:

I had one day — it was either before Thanksgiving or the day after Thanksgiving, I can't remember — I didn't throw up one time that day. I literally cried to my sister and mom I was like, 'It's over.' They said it would be abrupt and it would just end. Then the next day, nope, it just picked on right back up.

Unfortunately, Clarkson had a similar experience when she was pregnant with her son, Remi — to the point where she needed IV fluids, as she told CBS This Morning, per People.

For Molly Sims, throwing up was an around-the-clock thing during pregnancy. "In the morning, I wanna vomit. Lunch and I wanna vomit. I wanna vomit at dinner. Then when I go to bed, I still want to vomit," she said in a video on her website, according to Parents.

"The worst part about pregnancy would definitely have to be my nausea," Mowry said when she was pregnant with her son in 2012, NPR reported. "Mine happened in the morning, afternoon and in the evening and, not only did it just happen in the first trimester, it happened throughout my whole entire pregnancy." Thankfully, though, she only experienced nausea and vomiting toward the beginning of her second pregnancy, according to Us Weekly.
