When we examine a normal, healthy monthly cycle, we find that
estrogen is the dominant hormone from menstruation to ovulation. Then, in response to ovulation, estrogen levels fall, progesterone levels quickly rise and assume dominance during the final two weeks prior to menstruation. If during this two week period if there is a surplus of estrogen, a lack of progesterone or a blockade of progesterone receptors, Estrogen Dominance results and is most often followed by many of the unpleasant symptoms of PMS. Diet, stress and xenoestrogens (foreign oestrogens), often introduced in the form of contraceptives, are all major contributors to this disorder. The most marked changes usually occur the week before the onset of menstruation, but milder symptoms may occur at the time of ovulation. |
