The 61-year-old BJP leader attributed the incident to low sugar in his body.
"Had slight medical condition due to low sugar. I have been attended by doctors and I am doing well now. I thank all of you for all the well wishes," Gadkari tweeted.
A video grab of the event shows Maharashtra Governor Ch Vidyasagar Rao, who was standing beside him, supporting him while he fainted.
Gadkari was examined by a team of doctors present at the venue. His blood pressure was checked and he remained on his chair for about 10 minutes, after which he walked to his vehicle and proceeded to the nearby helipad.
