Hyperemesis gravidarum, the reason newly pregnant Kate Middleton is in the hospital, is a rare but acute morning sickness that results in weight loss,the condition is sometimes associated with women having twins, experts said.

Women diagnosed with hyperemesis gravidarum have lost 5 percent of their pre-pregnancy weight, or 10 pounds, said Dr. Ashley Roman, a professor and OB/GYN at New York University Langone Medical Center.

It poses little danger to the tiny heir, doctors said."It's traditionally thought that nausea and vomiting is a sign of a healthy pregnancy," Roman said

Dr. Nancy Cossler, an OB/GYN at University Hospitals in Ohio said the condition does not cause loss of pregnancy or birth defects, but it can be a torture to endure."The biggest problem with this is how it interferes with your life," Cossler said. "Constantly feeling sick and puking is difficult."
