On 6 September 2014, the Princess was admitted to
Vichaiyut Hospital due to stomach inflammation: she was later diagnosed with
gastritis and was advised to temporarily suspend royal duties. On 9 October 2014, the Princess was diagnosed with a severe infection of the
pancreas and swelling of the lymph glands: doctors concluded that she was suffering from an autoimmune disease called
systemic lupus erythematosus, which she has since begun to treat. Doctors advised her to stop activities for three months. She had been in hospital since the previous September. On 5 November 2015, Princess Chulabhorn underwent surgery at Vichaiyut hospital to remove seven
polyps from her large intestine. A blood test had previously shown that the princess had a higher than normal level of
carcinoembryonic antigen which indicated that she was likely to develop
cancer. In May 2016, the Princess was found to have a non-malignant
tumor in her neck, and it was removed at Vichaiyut Hospital. She had to suspend her official duties to recover after the operation and to treat her
pancreatitis, which she had been suffering from for a while and which was causing some health problems to her. As of July 2016, her pancreatitis was becoming intermittent and acute, a sign that it was worsening over time. To receive treatment, the Princess had to suspend her official commitments until she recovered. In June 2017, the Princess was diagnosed with lung, liver and muscle inflammation and low blood oxygen levels: she went to Vichaiyuth Hospital due to fatigue, shortness of breath and other symptoms and doctors made the diagnosis, and subsequently administered medical treatment to her. In February 2019, Princess Chulabhorn was admitted to
Ramathibodi Hospital in
Bangkok after developing back pain and blurred vision in both eyes. Doctors concluded that further tests were necessary and the Princess extended her stay in hospital. In April 2019, Chulabhorn underwent surgery to remove
cataracts (which had caused blurred vision) and underwent treatment for her newly diagnosed back infection (which caused back pain). Her recovery was confirmed a few days later. On 30 September 2019, Chulabhorn went to
Chulabhorn Hospital after experiencing numbness in her left hand. An
MRI showed that the nerves under her left elbow had become compressed, and as a result the Princess had to remain in hospital for treatment and suspend royal duties. As a result of numbness in her left hand, Chulabhorn had to undergo
microsurgery to remove the tissue causing the discomfort and remained in hospital until she fully recovered. On 16 June 2020, Chulabhorn underwent surgery at
Chulalongkorn Hospital due to numbness in the fingertips of her right hand, caused by a membrane compressing the nerve below her elbow. She was discharged approximately fifteen days later when she was judged to have recovered. In early October 2024, she had to suspend her engagements and activities for a while in order to proceed with rehabilitation, due to a surgery underwent two months earlier because of pain in her left foot and ankle at Chulabhorn Hospital in
Lak Si district. ==Honours and awards==
