Bolsonaro had initially complained of persistent hiccups.
The reason for this could be more serious than originally thought.
Brasília / São Paulo - Brazil's President Jair Bolsonaro has been relocated to the Brazilian metropolis of São Paulo for a possible emergency operation.
An ambulance took Bolsonaro from the military hospital in Brasília to the air force base in the capital of the South American country, as seen on Brazilian television.
The doctor had found an intestinal obstruction, according to a statement from the presidency press office.
He has decided to have the president taken to São Paulo, where further examinations will be made to determine whether an emergency operation is necessary.
The Brazilian President Bolsonaro was rushed to the hospital in Brasília early Wednesday morning on the advice of his medical team after an initial notification.
Accordingly, Bolsonaro was for examinations in the military hospital in the capital to find out the cause of his persistent hiccups.
The President was originally supposed to be under observation in the hospital or at home for 24 to 48 hours. He is fine, it said in the first message. Bolsonaro had complained of persistent hiccups in the past few days, which he also talked about in his weekly broadcast on social media. dpa
