King Bhumibol Adulyadej, 88, has not appeared in public for the past year due to poor health, AFP reported today. In recent months, the Thai royal family has regularly updated the king on his health, stating that he is experiencing several serious problems, including kidney failure.

Over the past two years, the king has been treated for numerous ailments, including bacterial infections, breathing difficulties, heart disease, and hydrocephalus. Doctors placed him on a ventilator after his blood pressure dropped following a procedure to remove fluid from his spine.

"The medical team is monitoring the symptoms and carefully planning treatment as the king's health is unstable," the Thai royal family announced.

King Bhumibol Adulyadej reigned for seven tumultuous decades, and his health was a common concern for many Thais. He was also protected by the world's strictest laws against defamation of the monarchy.
