Sirikit Kitiyakara Cause of Death: Thailand’s Queen Mother Dies at 93

Queen Mother Sirikit Kitiyakara, one of Thailand’s most revered royal figures, has died at the age of 93. The Royal Household Bureau confirmed that she passed away in Bangkok on Friday, October 25, 2025, due to complications from a bloodstream infection. Her death follows years of declining health and marks the end of a significant chapter in Thai history.

Sirikit had been hospitalized since 2019 for ongoing health issues and had largely withdrawn from public life after suffering a stroke in 2012. Her condition reportedly worsened in recent weeks before she succumbed to the infection. The Thai government announced a 30-day national mourning period, with flags to be flown at half-mast across the country.

Queen Mother Sirikit’s Health and Final Days

According to official reports, Queen Mother Sirikit had been under intensive medical care for several years. In mid-October 2025, she developed a serious blood infection, which became the immediate cause of her death. Despite continuous treatment by royal physicians, her condition deteriorated rapidly in the days leading up to her passing.

The Queen Mother’s body will lie in state at Bangkok’s Grand Palace, where members of the royal family, government officials, and citizens will pay their respects. The funeral will be conducted in line with royal traditions, including Buddhist ceremonies and state honors.

Prime Minister Srettha Thavisin has urged citizens to wear dark clothing and observe mourning customs. Schools, government institutions, and public offices will display the Thai flag at half-mast as a mark of respect for the late Queen Mother.

Legacy of Queen Mother Sirikit

Born on August 12, 1932, in Bangkok, Sirikit Kitiyakara became queen consort in 1950 upon marrying King Bhumibol Adulyadej (Rama IX). Her marriage lasted more than six decades, and together they were symbols of national unity and cultural continuity during times of great change in Thailand.

Throughout her life, Sirikit was celebrated for her humanitarian work, especially in rural development, women’s empowerment, and the promotion of Thai silk. Her dedication earned her the title “Mother of the Nation.” Following King Bhumibol’s death in 2016, she continued to be a respected maternal figure for the Thai people.

Her passing not only closes a long and influential chapter of Thai monarchy but also signifies the end of an era shaped by her compassion, strength, and commitment to her people.
