In 1981, Chulabhorn married Royal Thai Air Force officer Group Captain Virayudh Tishyasarin (Thai: วีระยุทธ ดิษยะศริน; RTGS: Wirayut Dityasarin), a commoner, an Air vice-marshal. They have two children: Princess Siribha Chudabhorn and Princess Aditayadorn Kitikhun. According to royal custom, she would have lost her title upon marrying a man of lower rank. However, they divorced in 1996, and she subsequently returned to the royal court.

Official duties

[edit]

The Princess visited Germany from 13 to 15 April 2010. During her visit she went to the German Cancer Research Center in Heidelberg to further her cancer research and to learn more about the developments the center had found. Princess Chulabhorn had visited the center already in 1986, 1995 and 2000.[5]

In November 2016, Princess Chulabhorn visited Japan and met with then-Emperor Akihito and then-Empress Michiko at the Imperial Palace, Tokyo. The Imperial couple hosted a luncheon in her honor.[6] During her visit to the country, The Princess went to Nagoya University, in Aichi Prefecture, to take part in a discussion between the "HRH Princess Chulabhorn College of Medical Science" in Thailand and the "School of Medicine" in the university.[7]

In March 2023, Princess Chulabhorn officially visited Israel: during the visit she toured the Hadassah Ein Kerem hospital, in Jerusalem.[8][9] Additionally, the Princess visited "Israel Diamond Exchange" with the Thai ambassador to Israel, Pannabha Chandraramya. At the event, Princess Chulabhorn discussed relations between Thailand and Israel. The president of the association, Boaz Moldawsky participated with the Princess in a ceremony in honor of the association.[10] During her visit to the country, the Princess went to the Western Wall (also called as the Wailing Wall), in Jerusalem, to pray. She also learned the importance of that monument to the country.[11]
In April 2023, Princess Chulabhorn visited the United States of America to attend the Health Summit for Pharmaceutical and Medical Development at Tufts University in Massachusetts.[12] The Princess also toured the institute and subsequently visited the NCI Frederick Campus in Maryland.[13]
In June 2023 Princess Chulabhorn also paid an official visit to Mongolia: during the visit she received an honorary Doctorate from the Mongolian University of Life Sciences, during the Princess's visit to the university headquarters in Ulaanbaatar.[14]

Health

[edit]

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.[15]

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.[16]

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.[17]

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.[18] 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.[19]

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.[20]

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.[21]

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.[22]

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.[23] 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.[24]

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.[25]

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.[26]

Health and medical history

Major health events and treatments

In September 2014, Princess Chulabhorn was admitted to Vichaiyut Hospital in for treatment of swollen lymph nodes in her stomach and a severe pancreatic infection, which medical examinations confirmed as manifestations of systemic lupus erythematosus (SLE), an . Palace officials announced the diagnosis on October 9, 2014, noting that the condition required ongoing management, and physicians recommended a three-month period of rest from royal duties to facilitate recovery. In June 2017, the princess experienced fatigue leading to another admission at Vichaiyut Hospital, where she was diagnosed with affecting her lungs, liver, and muscles, accompanied by low blood oxygen levels. Treatment involved hospital care to address the inflammatory conditions, with reports indicating improvement in her status by late June, though she suspended public engagements during this period. On October 1, 2019, Princess Chulabhorn was hospitalized again after reporting loss of sensation in her left hand, linked to complications from her SLE; this culminated in on her left arm on October 5, 2019, to alleviate compression. The procedure addressed symptoms exacerbated by the autoimmune disorder, with post-operative recovery allowing gradual resumption of activities.

Impact on duties and recovery

In October 2014, following a of severe pancreatic , Chulabhorn was advised by physicians to refrain from performing official palace duties during her recovery period, marking a temporary reduction in her public engagements to prioritize health restoration. This followed an initial hospital admission on September 6, 2014, for related complications, underscoring the 's acuity in limiting her royal responsibilities. In October 2019, after experiencing loss of sensation in her left hand—attributed to nerve compression confirmed by MRI—her public duties were suspended indefinitely pending medical evaluation and treatment, reflecting the condition's interference with routine activities. A subsequent procedure addressed the issue without complications, allowing focus on hospital-based recovery and physiotherapy to regain functionality. Recovery efforts across these episodes emphasized inpatient monitoring, surgical interventions, and rehabilitative therapies; for instance, post-2019 treatment involved structured to mitigate nerve-related impairments. By June 2020, following admission for right-hand fingertip numbness linked to circulatory factors, she was discharged after targeted interventions, resuming selective engagements thereafter. In October 2024, she underwent followed by intensive at Chulabhorn Hospital, aimed at addressing mobility challenges, though specific duty suspensions were not publicly detailed. These health episodes collectively prompted phased returns to duties, balancing medical oversight with gradual reintegration into scientific and royal roles.
