Brazil's imprisoned former president, Jair Bolsonaro, has undergone a second medical procedure in just three days to treat his persistent hiccups. Doctors performed a 'phrenic nerve block procedure' on Bolsonaro to block his left phrenic nerve, after previously treating the right one on Saturday. The phrenic nerve is crucial for controlling the diaphragm, which facilitates breathing.

Bolsonaro, currently serving a 27-year sentence for plotting to overturn the 2022 election, has faced ongoing health complications. Following another surgery for a double hernia, he has received treatment for chronic hiccups that have persisted for months.

Dr. Claudio Birolini reported that Bolsonaro's condition is stable after the recent procedure. He indicated that the hospitalization may not last much longer, with expectations for the former president to be discharged on January 1, provided he recovers well.

As Bolsonaro navigates these health challenges, he has endorsed his son Flávio to run against Brazil's President Luiz Inácio Lula da Silva in the upcoming 2026 presidential election.
