NBC NATIONAL NEWS — Most pregnant women know there is a chance they will have morning sickness, especially during the early stages of pregnancy. For some mothers-to-be the sickness is very severe.
Prince Williams has been visiting his pregnant wife Kate in a London hospital, where she is being treated for acute morning sickness.
The royal family announced Monday Kate is suffering from Hyperemesis Gravidarum, a rare condition that many describe as morning sickness on steroids or just out of control vomiting.
"A complete intolerance of anything by mouth, either fluid or food," said Dr. G. Daniel Robison, of the Glen Meade Center for Women's Health.
Melissa Burdett suffered the same condition when she was pregnant. She said she became worried when she started vomiting a lot more than usual.

Burdett had no idea being pregnant was going to be so frightening.
