Former Brazilian President Jair Bolsonaro’s kidney function has worsened at the intensive care unit to which he was transferred hours earlier, a hospital in the capital, Brasilia, said Saturday.

The 70-year-old leader was sent to DF Star Hospital on Friday from the prison where he is serving a 27-year sentence for leading a coup attempt in 2023.

Bolsonaro was admitted to the hospital after experiencing high fever, low oxygen, sweating, and chills. Exams confirmed bronchopneumonia, likely caused by aspiration.

The former president, who governed between 2019-22, has had an increase in inflammatory markers since treatment began.

One of his sons, Sen. Flávio Bolsonaro, is expected to run for president later this year against incumbent Luiz Inácio Lula da Silva.

“Unfortunately we have to learn how to live with this. It is not the first, the second or the third time my father is hospitalized because of the problems coming from the stabbing,” Flávio Bolsonaro told journalists.

Bolsonaro has been hospitalized multiple times since being stabbed at a campaign event before the 2018 presidential election. He was convicted on charges that include leading an armed criminal organization.

Jair Bolsonaro has denied any wrongdoing and claims he has received insufficient medical attention.
