Body weight plays a significant role in the regulation of menstrual cycles. Both underweight and overweight conditions can lead to menstrual irregularities. Women with low body weight often experience amenorrhea, the absence of menstruation, due to insufficient fat stores needed to produce adequate levels of estrogen. Conversely, excessive body weight can lead to irregular menstrual cycles or even amenorrhea due to hormonal imbalances such as increased estrogen production from adipose tissue.
