How Long Does Perimenopause Last?

Perimenopause can be a difficult and confusing transitional period, complete with a slew of perimenopause symptoms, challenging emotions, and unpredictable cycles. Whether you think you may be starting perimenopause, are in the thick of it, or may be nearing menopause, it’s natural to wonder: how long does perimenopause last?

Like most aspects of perimenopause, the duration of perimenopause can vary greatly from one woman to the next. Understanding perimenopause is key to managing its symptoms and knowing what to expect. We’ll dive into the specifics of perimenopause, its duration, and how to recognize what stage you’re in.

What is perimenopause?

First: let’s get a quick refresher on exactly what perimenopause is. 

Perimenopause means “around menopause.” Menopause comes after perimenopause as is the last 12 months after your last menstrual period. 

Also known as the menopausal transition, perimenopause are the few years (to many years) that come before menopause. During perimenopause, two key hormones—estrogen and progesterone—start to fluctuate and eventually decline. These hormones regulate your menstrual cycle, so when they start to shift, you’ll often start experiencing irregular cycles. 

These fluctuations can also cause a slew of physical and emotional symptoms, from hot flashes to brain fog.

When does perimenopause start?

Perimenopause typically begins in a woman’s 40s, but it can start as early as mid-30s. The onset and progression of perimenopause can vary significantly from person to person—factors like genetics, overall health, and lifestyle choices can influence when perimenopause starts.

Signs perimenopause is starting

Perimenopause often starts with irregular periods. When estrogen and progesterone start to fluctuate, they can disrupt your regular menstrual cycle schedule. These fluctuations can also cause a variety of other symptoms. These symptoms are quite common; up to 90% of women may seek out guidance from a healthcare provider to learn how to cope.

• Hot flashes: sudden feelings of warmth, often accompanied by sweating
• Night sweats: hot flashes that occur during sleep
• Mood swings: increased irritability, anxiety, or depression, as well as rapid changes in emotional states
• Sleep disturbances: difficulty falling asleep or staying asleep
• Vaginal dryness: Decreased estrogen can lead to less lubrication.
• Low sex drive: A lower interest in sexual activity.

Unfortunately, the first signs of perimenopause might be subtle, and it can be difficult to confirm whether you’re truly in perimenopause yet. If you track your hormones, however, you can get the confirmation and clarity you need about what fluctuations you might be experiencing and take action.

How long does perimenopause last?

Unfortunately, there’s no one true answer to “how long does perimenopause last?” The duration of perimenopause is different for every woman; however, on average, perimenopause lasts about four years.

For some, perimenopause may last only a few months. For others, perimenopause could last a decade. 

While it can be frustrating to not know exactly how long perimenopause will last, it’s because your body is unique — every woman responds differently to this natural transition. Understanding that perimenopause is a gradual process can help in managing expectations,  and learning more about your specific hormone levels can help in managing any symptoms and potential treatment strategies. 

How to tell you’re near the end of perimenopause 

If perimenopause can last anywhere from a few months to ten years, how can you tell when it’s ending? 

Your symptoms can be a good place to start. As you approach the end of perimenopause, your symptoms may change or even intensify. Be sure to look for:

• Longer gaps between periods: Periods may become less and less frequent before stopping altogether.
• More intense symptoms: Specific symptoms like hot flashes and night sweats may become more pronounced. 

While less regular periods and symptom changes can help you understand whether you might be nearing perimenopause, the best way to confirm you’re nearing the end of this transition is to look for stabilizing hormone levels.

Perimenopause is full of hormonal fluctuations, but these hormones level out toward the end of the transition. 

How do I know if I’m in menopause?

Menopause is officially diagnosed after 12 consecutive months without a menstrual period. At this point, the ovaries have stopped releasing eggs, and estrogen production has significantly decreased. 

Menopause symptoms may feel like perimenopause symptoms, and you may continue to have the same symptoms as you had during the premenopausal transition. The one symptom you won’t have, however, is irregular cycles or periods; instead, you will no longer have a period.
