Kate Middleton continues to fight extreme levels of morning sickness and now, her health has taken her away from her husband Prince William. According to a latest report, the Duchess of Cambridge is presently staying with her parents in Bucklebury in West Berkshire, England.

People broke the news on Tuesday, Oct. 7, 2014. A friend of the royal family told the celebrity news publication that Kate Middleton is "not at all well..."

"When you're ill, the place you feel most comfortable is at home with your mum, isn't it?" the source told the website.

Kate Middleton is suffering from medical condition called hyperemesis gravidarum (HG). The main symptoms of this pregnancy complication are severe nausea and vomiting that can lead to weight loss and dehydration. The palace made the big announcement of Duchess' second pregnancy on Twitter last Sept. 8, 2014. The news was followed by reports about deteriorating health of the princess.

Any person suffering from such a medical complication needs a relaxed environment to recuperate. Kate Middleton is reportedly able to find exactly like that at her mother's place, away from Kensington Palace. The source explains that Kate Middleton can simply "relax" in her Bucklebury residence while she does not have to "deal with the staff everything else that comes with a big palace full of rooms."

The report notes that Kate Middleton is under palace officials' supervision who keep regular check on her health. A source talked about Duchess' present condition and revealed that it is hard to say when she makes her next public appearance. However, they are hoping she recovers soon and take up new official engagements.

Caitlin Dean, the author of the book "Hypermesis Gravidarum - The Definitive Guide" says that women suffering from the this type of morning sickness usually start to feel better only after 16 weeks of pregnancy.

Meanwhile, it is known that Kate Middleton pulled out of several social commitments in the wake of her illness including Prince Harry's birthday dinner, solo trip to Malta and more. According to Express UK, the Duchess has cancelled her trip to Portsmouth. As per the royal source, she will not be making any public appearance until next week. It is said the Duchess last appeared on a social event last August 5 at the London Tower.

Kate Middleton is believed to be 11 weeks pregnant. Soon after the announcement of her second pregnancy, media outlets started speculating about her due date. According to OK!, the Duchess could give birth to Prince George's sibling in April 2015.
