How is Kate Middleton's health? What to know as Princess of Wales recovers from surgery

Catherine, Princess of Wales, is continuing to recover at home after undergoing abdominal surgery earlier this year.

The news that she had left the hospital came on Jan. 29, the same day her father-in-law, King Charles III, was discharged after undergoing a corrective treatment for a benign, enlarged prostate. Buckingham Palace has since announced the king has been diagnosed with cancer, which was caught during his procedure.

The palace said in its Jan. 29 statement: "The Princess of Wales has returned home to Windsor to continue her recovery from surgery. She is making good progress."

"The Prince and Princess wish to say a huge thank you to the entire team at The London Clinic, especially the dedicated nursing staff, for the care they have provided," the statement continued. "The Wales family continues to be grateful for the well wishes they have received from around the world."

Prince William was by his wife's bedside in a visit to the hospital on Jan. 18 as Kate recovered from abdominal surgery, palace officials said at the time.

The heir to the British throne left the London Clinic after spending time with the former Kate Middleton, Kensington Palace officials said.

Kate, 42, underwent a "planned abdominal surgery" on Tuesday and will be recovering in the hospital for the next 10 to 14 days, palace officials announced on Jan. 17.

William will be postponing appearances in the coming months and will not be conducting any official duties while his wife is in the hospital or immediately after she returns home, a Kensington Palace source told NBC News.

The princess was admitted to the London Clinic, a private hospital near Buckingham Palace, on Jan. 16 for surgery, palace officials said in a statement. They did not make it clear why she needed to have the surgery.

She is expected to be recuperating for two to three months, the palace source told NBC News. The palace said she was “unlikely to return to public duties until after Easter."

"The Princess of Wales appreciates the interest this statement will generate," the palace said. "She hopes the public will understand her desire to maintain as much normality for her children as possible; and her wish that her personal medical information remains private."

The princess's condition is noncancerous, a Kensington Palace source confirmed to NBC News.

The palace message added that Catherine "wishes to apologize" for having to postpone her upcoming engagements.

"She looks forward to reinstating as many as possible, as soon as possible," the statement said.

The royal family celebrated the Princess of Wales last month for her 42nd birthday on Jan. 9. A photo on Instagram showed her at the coronation ceremony last year for her father-in-law, King Charles III.

Her most recent appearance with William and their three children came during their annual Christmas church outing at the Church of St. Mary Magdalene in Sandringham, near one of the king's royal estates.

Catherine previously experienced health complications during each of her three pregnancies.

She had to be treated in the hospital for hyperemesis gravidarum, a severe type of morning sickness, when she was pregnant with the couple's oldest child, Prince George, 10.

She also experienced the condition during the early stages of her pregnancies with Princess Charlotte, 8, and Prince Louis, 5.

Hyperemesis gravidarum involves severe vomiting, nausea, weight loss and electrolyte imbalances.

The announcement about the princess's hospital stay was followed on Jan. 17 by Buckingham Palace officials sharing that Charles also needed treatment in the hospital. He underwent a corrective procedure Jan. 26 for an enlarged prostate.

On Jan. 29, Buckingham Palace released a statement announcing Charles had been discharged from the hospital and that the king has "rescheduled forthcoming public engagements to allow for a period of private recuperation."

On Feb. 5, the palace announced that Charles had been diagnosed with cancer following the procedure.

"During The King’s recent hospital procedure for benign prostate enlargement, a separate issue of concern was noted. Subsequent diagnostic tests have identified a form of cancer," the statement read. "His Majesty has today commenced a schedule of regular treatments, during which time he has been advised by doctors to postpone public-facing duties. Throughout this period, His Majesty will continue to undertake State business and official paperwork as usual."
