Bill Clinton was admitted to hospital in Washington on Monday after developing a fever, his office said.
The 78-year-old former US president, who has faced a series of health issues over the years, remained in “good spirits”, Angel Urena, his deputy chief of staff, said.
“President Clinton was admitted to Georgetown University Medical Center this afternoon for testing and observation after developing a fever,” Ms Urena said on social media platform X.
Mr Clinton was previously taken to hospital for five nights in October 2021 for a blood infection.
In 2004, at age 58, he underwent a quadruple bypass operation after doctors found signs of extensive heart disease. He had stents implanted in his coronary artery six years later.
The health scare motivated him to make lifestyle changes, including adopting a vegetarian diet, and he has since spoken publicly about his efforts.
Mr Clinton’s health last made headlines in November 2022 when he tested positive for Covid-19. He said at the time that his symptoms were “mild” and he was “grateful to be vaccinated and boosted”.
Mr Clinton, who led the United States for two presidential terms from 1993-2001, is the second-youngest living US president, after 63-year-old Barack Obama.
Though his prosperous time in office was marred by scandals, he has enjoyed a second life in the two decades after his presidency, which has seen him venture into numerous diplomatic and humanitarian causes.
