The Duchess of Cambridge, pregnant with her and Prince William’s first child, will remain in the hospital for a second day with hyperemesis gravidarum, or extreme morning sickness. St. James’s Palace issued a statement on Monday saying the duchess is expected to stay in the hospital for several days for the rare condition, which causes vomiting, severe nausea, and dehydration. But hyperemesis is a condition that is more common among women expecting twins, causing some speculation. The Duke of Cambridge spent Monday at the hospital with his wife.
