Big news out of Britain: the Duchess of Cambridge is expecting!

The announcement came after Kate Middleton was admitted to a London hospital for severe morning sickness.

Prince William's office confirmed the pregnancy, saying it's in the early stages.

Her Royal Highness is expected to stay in the hospital for several days and will then require at home rest as well.

The Duchess of Cambridge has been diagnosed with hyperemesis gravidarum, which is extreme morning sickness.

While 50 to 90 percent of pregnant women experience morning sickness, hyperemesis gravidarum is when the mother to be is unable to eat and becomes very dehydrated, throwing off the electrolytes.

Obstetrician/gynecologyst Dr. Jaggi Khairah with Kelsey-Seybold Fort Bend Clinic said, "If you're not urinating every four to six hours, or you see that your urine is becoming very dark colored, that's usually a good sign. If you feel like you've lost a significant amount of weight in the last 48 to 72 hours, anywhere from two to five pounds, those are all really good reasons to call your doctor and see if you need further treatment."

Khairah said at best, the condition lasts a week or two and for most, generally subsides by the second trimester.

Less than 10 percent of women though will experience extreme morning sickness all the way up until the birth of the baby.

Khairah said Kate is likely being treated with IV fluids and anti-nausea medication, keeping mom healthy and baby growing.

He explained, "They are very perseverant and even with mom going through periods of dehydration and decreased caloric intake, babies tend to do very well. Pregnancies will progress very well."

If you're experiencing morning sickness, Khairah recommends small, frequent meals. Even saltines every 45 minutes will help settle the stomach.

You can also try vitamin B6 over the counter.

Stay hydrated with water, popsicles and at-home medications, either dissolvable or taken by mouth, can certainly help.

The royal baby will become the third in line to the throne.

No word yet on a due date.
