Does levonorgestrel and ethinyl estradiol cause weight gain?

Depends: The dose can make a difference but over all birth control pills containing levonorgestral and ethinyl estradiol have not been shown to cause weight gain.That being said,I have had patients complain of both weight gain & weight loss with these pills.There is a tendency to start pills at the same times when weight gain frequently occurs - at the time u go off to college, marry, or after child birth.
