Dr. Mahathir's aide, Sufi Yusuf, confirmed to reporters that medical evaluations revealed no specific underlying pathology or acute medical emergency, attributing his hospitalization to extreme physical fatigue, acute emotional distress, and lack of sleep following his wife's passing at age 100 on September 28. Sufi noted that Dr. Mahathir's condition remains stable under medical observation. Tun Dr. Siti Hasmah, a pioneering medical practitioner and national public health advocate, married Dr. Mahathir in 1956. The late former First Lady was laid to rest in a state funeral attended by Malaysian King Sultan Ibrahim Sultan Iskandar. Dr. Mahathir served as Malaysia's fourth Prime Minister from 1981 to 2003 and returned for a second tenure from 2018 to 2020 at age 92, making him the world's oldest head of government.
