In October, Amy Schumer announced that she's pregnant with her first child with husband Chris Fischer. Unfortunately, she's been super-sick throughout her pregnancy 바카라 게임 웹사이트� and now, she's been hospitalized because of it.The 37-year-old Emmy winner posted to Instagram on Thursday, sharing she's currently in the hospital and will have to miss an upcoming show in Texas. "I'm fine. Baby's fine but everyone who says the 2nd trimester is better is not telling the full story," Schumer wrote. "I've been even more ill this trimester. I have hyperemesis ..." What exactly is hyperemesis?What Schumer is referring to is hyperemesis gravidarum (HG). You might recognize the condition because it's the same one Kate Middleton suffered from throughout all three of her pregnancies. Basically, hyperemesis gravidarum is a whole lot of vomiting during pregnancy, according to the U.S. National Library of Medicine 바카라 게임 웹사이트� the "extreme, persistent nausea and vomiting during pregnancy" can lead to dehydration, weight loss and electrolyte imbalances. HG is not morning sickness. Morning sickness typically happens during the first three months (a.k.a., the first trimester) of pregnancy and is common 바카라 게임 웹사이트� HG is much less common and more severe than morning sickness.Hyperemesis gravidarum symptoms are also pretty different from those of typical morning sickness (which are mainly decreased appetite, low-level nausea and sometimes vomiting). According to the NLM, women with HG experience the following symptoms:Severe, persistent nausea and vomiting during pregnancySalivating a lot more than usualWeight lossSigns of dehydration like dark urine, dry skin or weaknessConstipationInability to eat or drink an adequate amountWhile HG can happen during any pregnancy, the NLM says it's more common in pregnancies with multiple babies, or in women who have something called a hydatidiform mole (a rare mass or growth that forms inside the uterus at the beginning of pregnancy). Women who have had HG before or are prone to motion sickness also have a higher risk of having HG.While there isn't necessarily a cure for HG, treatment is available if symptoms are severe 바카라 게임 웹사이트� women might be admitted to the hospital (like Schumer) if they're severely dehydrated so they can receive fluids intravenously, per the NLM. If they also can't eat, doctors may begin feeding them intravenously or through a tube in their stomach. Another not-so-great thing: HG doesn't have a set stopping point. In some women, the symptoms last until week 14 or 16 of pregnancy 바카라 게임 웹사이트� but sometimes, women can experience the severe nausea and vomiting throughout their entire pregnancy. This isn't the first time Schumer's shared how wonderful, but also how miserable her pregnancy has been: Just a few days ago, Schumer shared on Instagram that though she was thankful for being nominated at the People's Choice Awards, she wasn't able to attend because "all I do is stand up and puke right now."Schumer also posted a video of an ultrasound appointment on Nov. 5 바카라 게임 웹사이트� in it, you can hear Schumer say she's "puking every day" because her baby is moving around so much.Schumer assured fans she will reschedule her shows in Texas soon.
