The pregnancy of Kate Middleton, the Duchess of Cambridge, is huge news around the world.
In fact, it caused so many hits that it crashed her official website Monday.
But the real concern is for her health.
She had to be hospitalized with an extreme form of morning sickness that causes more than the average amount of nausea and vomiting.
We spoke with the medical director of Ohio Valley Medical Center, who is also an OB/GYN.
Dr. George Jirak says morning sickness affects almost every pregnant woman at one time or another.
But he says what Kate Middleton is experiencing is beyond that.
He says Hyperemesis Gravadarum is an extreme form in which the expectant mother can't hold down any food or liquid.
He says these patients need to be hospitalized and given IV fluids.
"If it's not treated, it could result in serious complications which could include electrolyte disturbances, could have intractable vomiting to the point that it could have a tear in the esophagus, it could even result in renal failure which could be life threatening," said Dr. Jirak. "I suspect that the admission was at least precautionary, but it could be a more serious condition as well."
Dr. Jirak says there's good news, however.
He says morning sickness usually goes away after 12 to 16 weeks.
And here's another possibility.
This extreme form of morning sickness is more prevalent among women carrying twins, rather than one baby.
And that possibility already has royals-watchers wild with excitement.
