Has Kate Middleton had surgery in the past?
Kate underwent an operation when she was a child, though details of the surgery have never been revealed to the public.
The procedure left the future Queen with a three-inch scar on the left side of her head, which she often covers with her hair.
She also had an extensive hospital day during her first pregnancy with Prince George.
Kate was admitted to King Edward VII’s Hospital in 2012 for severe morning sickness caused by hyperemesis gravidarum.
She also suffered from the condition during her pregnancies with Princess Charlotte and Prince Louis but was treated at home rather than in hospital.
Kate 'keen to talk about health battle'
Kate Middleton is reportedly keen to open up about her health battle, but only when she returns to the public eye.
Palace sources told The Sunday Times: “She and William are at their most open when out interacting with the public.
“I can see a world in which the Princess might discuss her recovery out on engagements.
“If she was going to do it, that’s how she would do it.
“They appreciate the public’s love and affection for their children and know there is a public appetite to see them on their birthdays.”
Kate could return 'earlier than expected'
Kate Middleton could be eyeing an early return to royal duties as she continues to recover from her abdominal procedure.
The Princess of Wales is unlikely to return to the public eye until after Easter.
But Kate could appear alongside her family on Easter Sunday, joining her family for the traditional walk to church in Windsor.
