Kate Middleton has already been discharged from the King Edward VII Hospital but she still continues to endure acute morning sickness. This time, the Duchess of Cambridge will no longer head back to the hospital.

According to E!News, a representative for the Royal couple verified that Prince William already canceled his schedule to appear at the British Military Tournament at Earl's Court on Sunday due to his wife's condition. The Prince decided to stay by Kate's side as she recuperates from the delicate condition at the Kensington Palace.

"It is well known that hyperemesis gravidarum (acute morning sickness) often recurs and, until further notice, to allow the Duchess a degree of privacy during her pregnancy, we do not intend to offer regular condition checks or advise of routine developments associated with it," the representative said in a statement.

Prince William discussed his wife's condition with former Centrepoint Chairman Michael O'Higgins at the Winter Whites Gala on Saturday. "I don't know why they call it morning sickness. They should call it all day and all night sickness. It's a long old process but she is getting there. She feels like it is going to go on forever," Prince William said.

According to Figtree's Dr. David Greening, Hyperemesis Gravidarum (HG) affects about 1 in 200 women. Its symptoms include severe nausea and vomiting, dehydration, ketosis which is a rise in toxins in the blood, weight loss and low blood pressure.

Medical advances nowadays can easily treat the rare pregnancy condition. There are also simple cures that could somehow put a stop to morning sickness.

1. Avoid scents that trigger nausea.

2. Always have crackers to eat regularly.

3. Take a multivitamin at the time of conception. It may reduce the severity of the symptoms.

4. Taking Vitamin B6 or B6 plus doxylamine which is an antihistamine

5. Treatment with the steroid methylprednisolone may be effective for severe HG cases.

However, Dr. David Greening warns the pregnant women seeking medication for morning sickness that they should be fully aware on how safe the drugs are for them and the baby.
