The medical condition of Thai Princess Bajrakitiyabha has worsened as a ​result of multiple infections in several ‌organs, with physicians unable to contain her irregular heart rate, the Royal Palace said in ​a statement on Thursday.

The 47-year-old princess ​and eldest daughter of King Vajiralongkorn ⁠was taken to the hospital in December ​2022 after she collapsed from a heart ​condition and other infections. She has been in a coma ever since.

After years of treatment, physicians ​discovered a stomach infection that led ​to inflammation in her intestines in April, causing her ‌blood ⁠pressure to fall and her heartbeat to become irregular, the statement said.

She has been given medicine, and medical devices have ​been deployed ​to ⁠support her lungs and kidneys, but her health has continued to ​decline, the palace said, adding ​that ⁠doctors will continue to closely monitor her condition and provide further treatment.

Last year, Thailand’s ⁠influential ​Queen Mother passed away at ​the age of 93.
