THE STAGES OF MENOPAUSE

Every woman will experience menopause differently, and the transition can last anywhere from a few months to several years. But what happens at each stage? Explore the tabs below to find out more about the different phases of menopause.

PERIMENOPAUSE

Perimenopause is when you have symptoms of menopause, but you still have periods, although these may be irregular. This stage can last for 4 years or more.1

During this transition to menopause, the number of mature eggs in a woman’s ovaries lowers, making ovulation irregular.2 The production of three hormones in the female body also starts to drop: oestrogen, progesterone and testosterone.2,3 You can explore more about these hormones and how they cause the symptoms of menopause in the next tab.
