Brazil's President Jair Bolsonaro has been hospitalized following abdominal pain where he will be examined to determine whether he needs emergency surgery.

Brazil's Special Secretariat for Social Communication said on Wednesday that he had been admitted to a hospital in Sao Paolo.

The controversial far-right-winger president felt abdominal pain at night, and he was admitted to a hospital in Brasilia to investigate the cause of persistent hiccups.

Dr. Antonio Luiz Macedo, the physician who was responsible for surgeries on Bolsonaro following a knife attack in 2018, found an intestinal obstruction and decided to take him to a hospital in São Paulo, the report said.

The President has been complaining for more than a week of hiccups, saying it was causing him difficulties when speaking in public.

During a social media event last Thursday, the President said that he had had hiccups "for over a week" at that point. "I may not be able to express myself properly on this live," he said.

He has suggested the condition may be related to medication he was taking due to surgery for dental implants.
