BANGKOK: Thailand’s venerated but ailing 88-year-old monarch Bhumibol Adulyadej has been treated for heart trouble, high blood pressure and irregular breathing in recent weeks, the palace said in a statement Tuesday. Many Thais worship the king as a near-deity, and his frail health is a subject of significant public concern. He has spent most of the past two years hospitalized for a series of ailments, with few public appearances or speeches. Bhumibol is the world’s longest-reigning monarch with nearly seven decades on the throne, and most Thais have never known life under another king. Anxiety over what will happen after his reign comes to an end is considered an aggravating factor in the country’s past decade of tumultuous politics.
