Can Exercise Make Your Period Heavier?

Can exercise cause heavy menstrual bleeding? Summary. Intense exercise can cause changes in the hormones responsible for your menstrual cycle. It can cause you to have breakthrough bleeding when you are not on your period, lighter periods than you normally have, and sometimes, no period at all.

Does exercise increase menstrual flow? Yes, exercise can be very beneficial to you and your menstrual cycle in many ways! Overall activity and exercise helps regulate the menstrual cycle and flow, which also may equate to less cramping and lighter periods.

What makes your period flow heavier? If your hormone levels aren’t balanced, your body can make the lining too thick, which leads to heavy bleeding when you shed the thicker lining. If you don’t ovulate (release an egg from an ovary), this can throw off the hormone balance in your body, too, leading to a thicker lining and a heavier period.
