Heavy periods/Irregular periods

During perimenopause, you may find that your periods change and become unpredictable as your ovaries slow down and estrogen levels start to fluctuate. It can be very common for your cycle to become highly erratic and periods to be heavier and longer. One study found that among women ages 42 to 52, more than 90% experienced periods that lasted 10 days or more — with 78% reporting their blood flow as heavy.

As women approach menopause, there are fewer eggs to mature in the ovaries. The body releases more follicle-stimulating hormone (FSH) in an attempt to maintain normal ovulation, which produces more estrogen. This build-up of estrogen thickens the lining of the uterus, often resulting in heavier, longer periods. 

When is the bleeding considered heavy?

  • have to change tampons/pads every 2-6 hours.

  • requires double protection — such as a tampon and pad — to control menstrual flow

  • causes you to interrupt your sleep to change your pad or tampon

  • lasts longer than 7 days

When bleeding is heavy, it may last longer, disrupting your everyday life. You may find it uncomfortable to exercise or carry on with your normal tasks.

Heavy bleeding can also cause fatigue and increase your risk for other health concerns, such as anemia.

We recommend you consult a doctor if your periods are exceedingly heavy.
