Nasheed, the president of the ruling Maldivian Democratic Party and the current parliament speaker, was critically injured after a bomb exploded as he left his family home in the capital Male on Thursday.
"I'm good," Nasheed said after coming off life support, according to a tweet by his sister Nashida Sattar.
Nasheed, the Maldives first democratically elected president who is now parliament speaker, had previously warned about militants infiltrating the Islamic country. He was getting into his car when the blast occurred.
"Over the course of the past 16 hours he had life-saving surgery on injuries to his head, chest, abdomen and limbs," the hospital said in a statement.
