Dr Noble’s Takeaway

• Menopause is the stage of life when the ovaries are no longer producing eggs, defined once 12 months have passed since the last cycle. A person is then in Menopause for the duration of their life, with some symptoms lasting for decades, while other symptoms can improve over time.
• Perimenopause runs about four years for most women, anywhere from two to eight or more-it is the time leading up to and one year beyond the final menstrual period (FMP).
• Hot flashes and night sweats lasted a median of about seven and a half years in the SWAN cohort (a study of women in the US), and much of that time came after the final period.
• Vaginal and urinary symptoms are the exception. They tend to progress rather than ease. Moreover, treatment can be started at any time-best at the onset of symptoms, but even decades after to provide relief of symptoms and decrease the risk of Urinary Tract Infection (UTI).

This is one of the first questions I am asked in the office, and it is one of the hardest to answer in a sentence. Not because we do not know, but because the question contains three different questions, and the answer changes depending on which one you meant.

Menopause itself has no duration at all. Symptoms do. And different symptoms behave in completely different ways.

Menopause is a day, not a season

Menopause is the day you have gone twelve consecutive months without a period. That is the whole definition. It occupies a single date on a calendar.

So when someone asks how long menopause lasts, they are often asking about the menopausal transition-the time from changes in the cycles, including the year after that final menstrual period. Furthermore, they are often asking about the symptoms, wondering how long their symptoms will last. That’s complicated because it depends what symptoms we are talking about.

I find that clearing this up first makes the rest of the conversation much easier, because it separates a milestone from an experience.

The transition itself runs about four years

Perimenopause, the stretch before menopause, lasts about four years for most women. The range around that average is wide. Some women move through it in two. Others spend eight years or more in it, and that is still within normal variation. What is most important, is supporting you through your symptoms, no matter when they appear and having a positive impact on your quality of life and overall health.

Menopause is a retrospective diagnosis-think looking in the rear view mirror. We can only define it after 12 months have elapsed since the last cycle. This can be especially confusing for women who do not have bleeding symptoms (hysterectomy, endometrial ablation, contraception that regulates or mitigates cycles). Lab testing is not usually very helpful, but can be helpful in certain circumstances. I would focus less on defining the date of the final menstrual period (FMP) and more on controlling the symptoms and supporting your health and wellness with numerous options that we can tailor to your unique journey.

Hot flashes do not stop when your periods do

In the Study of Women’s Health Across the Nation, a large United States cohort followed over many years, the median total duration of hot flashes and night sweats was around seven and a half years. Roughly four and a half of those years fell after the final period.

Individual variation is considerable, and symptoms carrying on into the mid fifties are common rather than exceptional. The same study found that women whose symptoms started earlier in the transition tended to have them for longer overall, while later onset was associated with a shorter run.

I mention this because the phrase I hear constantly is some version of “I will just get through it.” You get through the transition and then you are in menopause. Many symptoms will last for up to a decade and there are important implications for your overall health in menopause-increased risks for osteoporosis, obesity, diabetes, cardiovascular disease. Treatment decisions should be based on these factors, your personal and family history, your preferences, as well as your symptom burden.

Some symptoms never settle on their own

Vaginal dryness, discomfort with sex, urinary urgency and recurrent urinary tract infections follow a different course from everything else. They do not ease with time. Without treatment they usually get worse.

The reason is mechanical rather than mysterious. Those symptoms come from changes in the tissue itself, and the tissue keeps changing for as long as estrogen stays low, but the symptoms can be easily mitigated with local, vaginal options that carry minimal to no risk.

Why perimenopause is often the worst stretch

Symptoms driven by hormonal fluctuation tend to settle once levels are low and steady. Think: cyclical breast tenderness, bloating, heavy or irregular bleeding, worsening premenstrual symptoms.

When ovulatory cycles finally stop, some women feel better rather than worse-especially women who have experienced bothersome premenstrual symptoms or painful periods (endometriosis).

Postmenopause is the longest stage of all

Postmenopause begins at the twelve-month mark and continues for the rest of your life. With current life expectancy, most women now spend approximately a third of their lives in it.

I say that plainly because framing menopause as an episode to survive implies that you come out the other side and return to how things were. There is a new baseline, a new stage of life. I want you to understand this so that you can make informed decisions about your care.

The clinical priorities change with it. During the transition, we are mostly talking about symptoms. Afterward, bone density and cardiovascular health move to the front of the conversation, as these have long term impacts on our health and longevity.

Underneath the question, most women are really asking whether it will end. For hot flashes and night sweats, the answer is generally yes, over years rather than months. For vaginal and urinary symptoms, the answer is that treatment changes the course wheras time does not.
