The Duchess of Cambridge leaves hospital

The Duchess of Cambridge today left hospital, with husband Prince William at her side, describing herself as feeling ‘much better’ after four days of treatment for severe morning sickness.

Kate emerged from the King Edward VII Hospital in central London smiling and carrying a bouquet of yellow roses.

Wrapped up against the cold in a frock coat and scarf, she looked relaxed and well after her treatment.

The pair posed briefly for the phalanx of photographers and reporters who were waiting outside. When asked how she was feeling she smiled and said ‘much better’ before being driven away by her husband.

In a brief statement, St James’s Palace said: “The Duchess of Cambridge has been discharged from the King Edward VII Hospital and will now head to Kensington Palace for a period of rest.

“Their Royal Highnesses would like to thank the staff at the hospital for the care and treatment the Duchess has received.”

Prince William, casually dressed in a dark top and matching trousers, had arrived at the hospital at 10.15am and walked into London’s King Edward VII hospital without acknowledging the waiting press.

Kate was admitted to hospital on Monday after developing severe morning sickness known as hyperemesis gravidarum.

The condition can leave patients feeling tired, dizzy and suffering from headaches – all signs of dehydration. But it now appears that she has responded well to the treatment which reportedly included time on a drip.

The Queen’s former gynaecologist Marcus Setchell, who delivered the Countess of Wessex’s two children, is among the team of doctors who treated her

The prolonged vomiting could continue for much of her pregnancy – which is still below 12 weeks – and she may need to take anti-sickness medication for months to come.

William has been at his wife’s bedside every day since taking her into hospital after she fell unwell over the weekend.
