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  reduced the boundaries of the constituency. Previously it had also included one union parishad of Dowarabazar Upazila: Mannargaon.
