Menopause is technically defined as the point at which there are no more follicles in your ovaries capable of ovulating and is marked by one full year after your final menstrual period. But the term is often used as a catch-all to describe premenopause, the menopause transition and postmenopause.

The average age of menopause is between 50-52 years.

One of the earliest signs of menopause is an increase to the length of your menstrual cycle by 7 or more days and the occasional missed periods. Most people do not experience other symptoms like insomnia or hot flashes until later, but it is possible to experience symptoms early on, as well.

The menopause transition can be very different from person to person since many factors play a part, like genetics, your environment and past experiences. But if a person begins to skip two periods in a row (i.e. more than 60 days between periods), then they will likely experience menopause within the next 4 years.

When menopause occurs before the age of 40, this is considered early menopause, also known as primary ovarian insufficiency (POI). POI is rare, affecting 1% of those with vaginal anatomy and, in most cases, there is no known cause. Early menopause can also occur due to surgical removal of the ovaries or pharmaceuticals that deplete estrogen.

Perimenopause or menopause transition refers to the years leading up to menopause when periods become more irregular, hormones fluctuate, and symptoms develop. Menopause is marked by one year without periods. Postmenopause applies to the rest of your life after menopause. Most women will spend almost half of their life in these stages of menopause.

Since menopause symptoms can vary enormously from person to person, treatment will depend on the individual's medical history, symptoms and preferences. Treatment strategies can include vaginal creams or lubricants, prescribed medications, hormone replacement therapy, physical therapy and modifications to diet and exercise.
