KUALA LUMPUR (Kyodo) -- Former Malaysian Prime Minister Mahathir Mohamad, 96, was discharged from a hospital in Kuala Lumpur Thursday after spending a week for "a series of medical investigations," the hospital said in a statement.
The National Heart Institute did not elaborate on the veteran politician's condition or what prompted him to be admitted to the hospital on Dec. 16.
Mahathir, who was premier twice, had had many health scares in the past. He had his first heart bypass in 1989, and the second one in 2007. But he has been active in politics after these surgeries.
On Tuesday, while being hospitalized, Mahathir issued two press statements to comment about recent floods affecting Malaysia.
Mahathir first assumed power in 1981 and become the longest-serving prime minister in the country when he retired 22 years later in 2003.
In 2018, he joined forces with the opposition and stunningly dethroned the long-ruling National Front coalition.
He made history by becoming prime minister for a second time at the age of 92, though his tenure was short-lived as his government collapsed in less than two years due to political defections.
