Why do hormones cause so many problems?
First of all, they prevent more problems than they solve. Female hormones enable the body to become adult at puberty and make it possible to continue the human species. They probably play some role in forming personality and they give women a longer lifespan than men. Because hormones have so many different effects, they may have positive effects on one part of your body and negative effects on another. Also hormone levels fluctuate and the resulting instability of body chemistry can be uncomfortable.
