Perimenopause at 48: What to Expect, How Far Along You Are, and What to Prioritize Now

If you're 48 and wondering what's happening to your body, there's a good chance you're deep in the perimenopause transition. At 48, most women are somewhere in the middle to later stages of perimenopause, though the range varies. Some women at this age are still in early perimenopause. Others are close to the final menstrual period. Most are somewhere in between, experiencing a shift that feels more like a slow unraveling than a single event.

What you're experiencing is real and it is biological. The symptoms that feel like too much, including sleep that has fallen apart, a body that feels unfamiliar, a brain that won't cooperate, are not character flaws or overreaction. They are the result of significant hormonal change that your body is working its way through.

This article explains what perimenopause at 48 typically looks like, how to get a clearer sense of where you are in the transition, what long-term health priorities deserve your attention right now, and what treatment options are available at this stage.

What perimenopause at 48 typically looks like

The average age of menopause (defined as 12 consecutive months without a period) is 51 to 52 in the US. Perimenopause typically lasts four to ten years before that point. Which means that at 48, most women are somewhere in the middle of that window, with a few years of transition still ahead.

In mid-to-late perimenopause, the hormonal pattern shifts. Estrogen levels become more erratic and broadly lower, progesterone continues to decline, and the gaps between periods often widen. You may start going two, three, or four months between periods. Alternatively, your cycles may still arrive monthly but with dramatically different flow, length, or character than they had in your 30s.

Symptoms that are common at this stage include more intense and frequent hot flashes, night sweats that weren't present in earlier stages, more pronounced mood fluctuations and anxiety, heavier cognitive fog, increased vaginal dryness, declining libido, and joint discomfort. It's also common for symptoms that were manageable in earlier years to intensify as estrogen levels drop lower and stay lower.

Some women at 48 experience what feels like a sudden escalation, a point where the symptoms shift from occasional to daily and significant. This is often the late perimenopause phase where estrogen decline becomes steeper. It doesn't mean something has gone wrong. It means the transition is progressing.

How to gauge how far along you are

There's no blood test that definitively stages perimenopause. FSH (follicle-stimulating hormone) levels rise during perimenopause as the pituitary gland pushes harder to stimulate the ovaries, and elevated FSH (generally above 10-12 IU/L, though labs vary) indicates perimenopause is underway. But FSH fluctuates significantly from cycle to cycle, so a single reading is not a reliable staging tool.

AMH (anti-Mullerian hormone) is a more stable marker. It reflects ovarian reserve and declines steadily throughout the transition. Low AMH at 48 suggests you may be closer to the end of the transition. Your doctor can order both tests.

For a simple self-assessment, consider the STRAW+10 staging system, which researchers use to categorize reproductive aging. It uses cycle regularity and variability as staging criteria. Late Stage -2 (late perimenopause) is defined by cycles that vary by more than 60 days in length. If you are regularly going two or more months between periods, you are in late perimenopause by this definition. You can discuss this staging with your provider to get a clearer picture of where you are in the transition timeline.

The most practically useful staging markers are your cycle changes:

Early perimenopause: Cycles still mostly regular but shifting in length (shorter or longer), PMS changes, subtle new symptoms.

Late perimenopause: Cycles skipping regularly (60 days or longer between periods), more pronounced symptoms, likely the stage many 48-year-olds are in.

Approaching menopause: Going 3 or more months between periods. Hot flashes and sleep disruption are often most intense in this phase.

The Menopause Rating Scale (MRS) is a self-assessment tool you can find online that helps quantify your symptom burden across somatic, psychological, and urogenital domains. It's not diagnostic, but it gives you a useful benchmark for tracking whether things are improving or intensifying over time.

Symptoms that may be new at this stage

In mid-to-late perimenopause, some symptoms appear or intensify that many women don't expect and didn't experience earlier in the transition.

Genitourinary symptoms. As estrogen levels drop lower, vaginal tissue thins and loses moisture. This can cause dryness, irritation, pain during sex, and increased susceptibility to urinary tract infections. These symptoms, collectively called genitourinary syndrome of menopause (GSM), affect the majority of women in late perimenopause and postmenopause. Unlike hot flashes (which often improve over time), GSM doesn't resolve on its own without treatment. It's very treatable with local (vaginal) estrogen, which has minimal systemic absorption and is considered safe for most women.

Sleep architecture changes. In late perimenopause, some women find that sleep disruption shifts from night sweats and hot flashes to something more like insomnia proper: difficulty falling asleep, early waking, and unrefreshing sleep even on nights without temperature disruption. This reflects changes in progesterone (which supports GABA and healthy sleep architecture) and shifts in cortisol regulation.

Joint pain and stiffness. Estrogen has anti-inflammatory properties. As levels decline, some women develop or worsen joint pain, stiffness on waking, and what sometimes gets diagnosed as perimenopause-related arthralgia. This is real and can be significant. Strength training, omega-3 fatty acids, and appropriate treatment can help.

Cognitive changes. Mid-to-late perimenopause is often when brain fog becomes more pronounced. Difficulty with word retrieval, short-term memory gaps, and reduced processing speed are common. These symptoms are real and hormonally driven. For most women they improve after the transition to postmenopause.

Long-term health priorities to address now

At 48, the window for building long-term health is open. The decisions you make in this perimenopause transition have compounding effects on your health in the decades ahead.

This is not meant to be alarming. It's meant to be clarifying. The behaviors that protect bone density, cardiovascular health, metabolic function, and cognitive health in later life are the same behaviors that help you feel better right now. You're not sacrificing present quality of life for future outcomes. You're investing in both at the same time.

Bone density. Women can lose up to 20 percent of their bone density in the decade surrounding menopause, with the steepest decline occurring in the late perimenopause and early postmenopause years. Getting a baseline DEXA scan at or around menopause (sooner if you have risk factors like a family history of osteoporosis, low body weight, or long-term steroid use) tells you where you're starting from. Building bone density now through strength training, calcium-rich foods, and adequate vitamin D is the most effective strategy available. Once bone is lost, restoring it is harder than protecting it.

Cardiovascular health. Estrogen has protective effects on the cardiovascular system. As estrogen declines, cardiovascular risk for women begins to catch up with risk for men. The late perimenopause window is an important time to address blood pressure, cholesterol, blood sugar, inflammatory markers, and smoking if any of these are factors. Lifestyle changes (diet quality, consistent movement, sleep) are the foundation. Your provider can order a lipid panel, fasting glucose, and other cardiovascular markers if you haven't had them recently.

Metabolic and blood sugar health. Insulin sensitivity declines with estrogen. Many women notice changes in body composition at this stage, particularly increased abdominal fat, even without changes in diet. This is partly metabolic and partly the redistribution of fat that happens when estrogen levels fall. Protein intake, strength training, and reduced refined carbohydrate consumption are all evidence-backed strategies. Fasting blood glucose and HbA1c (a 3-month blood sugar average) are worth tracking.

Cognitive health. Sleep quality, cardiovascular health, physical exercise, and metabolic stability are all protective against cognitive decline. The choices you make during perimenopause do affect your brain's long-term trajectory. This isn't meant to frighten you. It's meant to give the habits in this article additional weight.

Treatment options at this stage

At 48 in mid-to-late perimenopause, your treatment options are broad and well-supported by evidence.

Hormone therapy (HRT/MHT). Menopausal hormone therapy is the most effective treatment for hot flashes, night sweats, sleep disruption, vaginal symptoms, and mood instability. For women without contraindications, starting hormone therapy in perimenopause or within ten years of menopause carries the strongest safety and benefit profile. The "timing hypothesis" in menopause medicine now suggests that starting HRT early in the transition, rather than waiting until postmenopause, may also provide cardiovascular and cognitive protective benefits. Talk to your provider or a menopause specialist about your individual risk factors and options.

Local vaginal estrogen. For genitourinary symptoms (dryness, irritation, urinary symptoms), local vaginal estrogen (cream, ring, or tablet) is highly effective and has minimal systemic absorption. It is considered safe even for many women who cannot use systemic HRT. This is separate from systemic HRT and can be used alone or alongside it.

Non-hormonal options. For women who cannot or prefer not to use hormone therapy, several non-hormonal treatments have meaningful evidence: SSRIs and SNRIs (particularly venlafaxine and paroxetine) reduce hot flash frequency. Fezolinetant (Veozah), a neurokinin receptor antagonist, was approved in 2023 specifically for moderate to severe hot flashes and works through a non-hormonal mechanism. Cognitive behavioral therapy (CBT) and clinical hypnosis have good evidence for hot flash management.

Lifestyle as a treatment layer. Diet quality, strength training, sleep optimization, and stress reduction all have direct effects on symptom severity. These are not alternatives to medical treatment. They are the foundation that makes any treatment more effective.

PeriPlan can help you connect your day-to-day habits to your symptom patterns so you can have clearer, more specific conversations with your provider about what's working and what isn't.

Mental health at this stage deserves direct attention

Many women at 48 are surprised by how significantly perimenopause affects their mental and emotional life. Not just mood swings, which are common, but a more pervasive shift in anxiety baseline, emotional reactivity, and in some cases a first onset of depression in women who have never experienced it before.

This is not a character change. It is not burnout (though it can look like it). It is partly hormonal: estrogen supports serotonin and dopamine production. Progesterone supports GABA. As both decline, the brain's emotional regulation chemistry shifts. This is real, measurable, and treatable.

If you are experiencing significant anxiety, persistent low mood, rage disproportionate to circumstances, or a loss of interest in things that used to matter to you, this is worth bringing up explicitly with your provider, separate from the physical symptom conversation. HRT can significantly improve mood symptoms for many women by restoring hormonal support for neurotransmitter production. For some women, short-term antidepressants or anti-anxiety medications are appropriate additions. Therapy, specifically CBT and acceptance-based approaches, is also well-supported for perimenopausal mood changes.

You do not have to white-knuckle through the emotional side of this transition. There are effective options and you deserve access to them.

What to bring to your next appointment

Many women at 48 are not yet working with a healthcare provider who specializes in perimenopause. General practitioners and even some gynecologists have limited training in menopause medicine. This is changing, but the gap is real.

If you're not getting the care you need, the Menopause Society (formerly NAMS) and the British Menopause Society both offer practitioner finders that can help you locate a certified menopause specialist.

When you do see a provider, come prepared. Document your most impactful symptoms, how frequent and severe they are, and how they're affecting your daily life. Bring your cycle data. Note any changes in sleep, mood, cognition, and physical symptoms. Ask specifically about bone density screening, cardiovascular risk assessment, and the appropriateness of hormone therapy for your situation.

You are not too young to be taken seriously about this. You are not "just stressed." You are 48, you are in the middle of a significant hormonal transition, and you deserve care that reflects that reality.
