Reports say Gadkari fainted due to low blood sugar in his body and was given something sweet to chew by the doctors attending him.
The 61-year-old BJP leader was in Ahmednagar for the convocation ceremony of the Mahatma Phule agricultural college.
In 2010, while he was in the Opposition, Gadkari fainted standing atop a vehicle while on his way to Jantar Mantar for an anti-price hike rally.
