Kate Middleton's pregnancy sickness that has been diagnosed as Hyperemesis Gravidarum, is reportedly getting worse that she's constantly being monitored by her doctors. It takes not just one, but supposedly two doctors to ensure she's still in good health.

The Duchess of Cambridge has been suffering for weeks now with Hyperemesis Gravidarum. Her pregnancy sickness has been so severe that she's forced to pull out on numerous royal engagements. People even cited palace sources who claim that her condition is being monitored on a day-to-day basis. Likewise, her engagements are also being evaluated daily in case she couldn't commit.

However, Kate Middleton's pregnancy sickness continues despite previous claims that she's ready to resume with her royal duties on October. A family friend told People that she "is not at all well." Her nausea is reportedly worse than before that she's even lost weight from too much vomiting. Boston Herald's Kevin O'Leary claimed two doctors are constantly checking on her health. One of them is Dr. Alan Farthing, who has reportedly been an "angel during rougher moments" in the Duchess' pregnancy.

Additionally, the Duchess is reportedly too ill to even enjoy the simple pleasures of watching her favourite TV show, "Downtown Abbey." A family friend claimed that it's been difficult for Kate Middleton. She has even retreated to her hometown in Bucklebury to be with her parents.

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

There is still no definite timeframe as to when Kate Middleton will return to public appearances. Her pregnancy sickness could last for up to 16 weeks and the Duchess is believed to still be around ten weeks pregnant. The Duchess of Cambridge also suffered Hyperemesis Gravidarum when she was carrying her firstborn, Prince George. It's assumed she will resume with her royal duties on the 13th week as she had before. Likewise, Lesley Page, one of Britain's leading midwives, assured that the sickness usually dissipates at the 12 to 16 weeks point. However, with two good doctors monitoring her pregnancy, Kate Middleton is expected to be on her feet again in no time.
