It's a classic movie scene. The woman finds herself running to the bathroom to throw up, and suddenly it dawns on her, "I'm pregnant." Indeed, morning sickness is one of the classic signs of pregnancy, and some 85 percent of pregnant women will feel nauseated and throw up in the first trimester. But that's not every mom's story. For 2 percent of expectant mothers, an extreme morning sickness called hyperemesis gravidarum sets in sometime before the ninth week of pregnancy.
They're not just a little nauseous. They can't keep anything down. They're losing weight. They're dehydrated. Their OB/GYN is throwing around words like "ketones in the urine" and "liver abnormalities."
Hyperemesis gravidarum, or HG as it's commonly called, is one of the most common causes of hospital admissions for pregnant women. And unlike a mom suffering from run-of-the-mill morning sickness, a woman with HG will have unrelenting nausea and vomiting with no other obvious cause.
