Pohoomull joined the programme just over a year ago, since which her character has briefly had relationships with Sean and Bradley.
Show producers decided to let the character go after she failed to make an impression on the audience.
A BBC spokesperson said: "Preeti will leave Albert Square in early 2008. We wish Babitha all the best in her career."
Preeti will leave Walford after Mickey rejects her and she decides that there is nothing left for her in Albert Square.
