Amy Schumer and Kate Middleton Have This Pregnancy Complication in Common

Amy Schumer was forced to cancel some upcoming stand-up shows due to pregnancy complications.

She explained on Instagram on Thursday that instead of performing, she landed in the hospital with hyperemesis gravidarum, a severe morning sickness some women get while pregnant.

“Texas I am so deeply sorry. I have been really looking forward to these shows. I have to reschedule. I am in the hospital. I’m fine. Baby’s fine but everyone who says the 2nd trimester is better is not telling the full story. I’ve been even more ill this trimester. I have hyperemesis and it blows. Very lucky to be pregnant but this is some bulls**t! Sending so much love to the doctors and nurses taking great care of me and Tati! They are cool as hell! And Texas I am really really sorry and I’ll be out there as soon as I’m better.”

Kate Middleton suffered from the same complication during her pregnancies and was forced to cancel royal appearances due to extreme nausea. Summer House's Ashley Wirkus also recently complained of having severe morning sickness, too. So how dangerous is it?

Nicole Avena, Assistant Professor of Neuroscience, Mount Sinai School of Medicine, and author of What to Eat When You’re Pregnant, explained the condition to Personal Space:

“Hyperemesis gravidarum is a severe form of morning sickness that can be characterized by excessive vomiting, extreme nausea, and weight loss. It can pose a danger because it can lead to dehydration,” she said. “We don’t know exactly what causes it, but the nausea associated with it is caused by increased hormone levels that occur in early pregnancy.”

She added that if you think you are experiencing more than just the typical pregnancy queasiness, it is best to contact your doctor. “Mild forms of this condition can be treated with rest and some diet changes, but extreme forms may require IV hydration.”
