Irregular Periods Explained: The Main Reasons Why Your Period Is Out of Whack

Exercise

A woman’s body needs sufficient energy to menstruate properly. If a woman is exercising excessively to lose weight and burning too much of her energy at the gym, there will be no energy left for her body to draw from during her menstrual cycle. One of the hormones present during a woman’s menstrual cycle - called leptin - is stored and produced in the fatty tissue. Training excessively and influencing drastic weight loss changes can decrease body fat, causing this and other hormones to drop and contributing to an irregular period.
