Why do birth control pills affect all women differently?

Because different birth controls have different hormone levels, and different women have different hormone levels. If a woman has a higher than average level of a particular hormone, and takes a birth control with that hormone in it, she will have more of that hormone in her system than another woman on the same birth control would. Depending on the hormone, this can increase her chances of adverse side effects and it may even in some cases, decrease the effectiveness of the birth control for her.

Because all women are different. There are no clones. We all have different genes and different things passed on from out parents. Some of us are allergic to things, some of us have skin conditions. Every woman is different, just like every person in the world is different from the other.

I gave the pill up years in the past. I switched to the coil. maximum suitable selection in case you ask me. No factor outcomes, i don't even get a era, purely some recognizing each 3 months. Bloody dazzling. No hormone imbalance, no traumatic remembering to take it on an analogous time widely used! dazzling.

everyone's DNA is different right? well, every woman's hormones are unique, just like DNA, ANY medicine will affect everyone differently we are all different not the same...and also Yaz is new, very new just FDA approved, so....reconsider that exact pill, ask your doctor if that brand is right for you....

Because not all women are the same. We are all different and it will react different to everyone.

because every women is different
