The constituency was created for the first general elections in newly independent Bangladesh, held in 1973.
Ahead of the 2008 general election, the Election Commission redrew constituency boundaries to reflect population changes revealed by the 2001 Bangladesh census. The 2008 redistricting altered the boundaries of the constituency.
Ahead of the 2014 general election, the Election Commission expanded the boundaries of the constituency. Previously it had excluded three union parishads of Patuakhali Sadar Upazila: Auliapur, Kamalapur, and Lohalia.
