Aug. 19, 2003 -- Obese women may be more likely to develop breast cancer largely because their bodies produce more estrogen than thin women do. New research suggests that the increase in breast cancer risk faced by obese postmenopausal women may largely be due to higher levels of estrogens circulating in their bodies.
So estrogen can be directly responsible for weight gain. Estrogen is also the hormone in the female body responsible for ovulation. It is the reason women can produce eggs and these eggs fertilize with sperm to form a baby. Estrogen can increase due to many reasons including birth control pills and menopause. Birth control pills add to the existing hormone in the body and increase the womanâs appetite. This, in turn, leads to weight gain. In the case of menopause, hormonal fluctuations lead to an increase in appetite and eventual weight gain. During menopause, the body rapidly produces lesser hormones to stop ovulation.
