In a resignation letter addressed to Speaker of Parliament Hafiz Uddin Ahmad, Shahabuddin, who was elected as Bangladesh's 22nd president on 24 April 2023, said he suffered from heart disease, high blood pressure, diabetes and kidney complications, and had undergone heart bypass surgery. He said recent medical examinations had also diagnosed him with a condition called Autonomic Neuropathy, which caused him to occasionally lose consciousness for short periods. "Due to the progression of these medical conditions and the resulting physical and mental incapacity, it is no longer possible for me to discharge the responsibilities of the highly important constitutional office of the President," he wrote.
