Perimenopause is the transition leading up to menopause, when hormone levels begin to fluctuate and menstrual cycles often become less predictable. It most commonly begins in the 40s, although changes can start earlier, and may last for several years.
This transition can affect periods, sleep, mood, temperature regulation, sexual and vaginal health, and overall well-being. Every person's experience is different: some have few symptoms, while others notice changes that significantly affect daily life. The good news is that there are many ways to manage bothersome symptoms. Understanding what is happening and the treatment options available can help you navigate this transition with confidence.
Perimenopause is the natural transition between the reproductive years and menopause. During this time, estrogen and progesterone levels fluctuate, ovulation becomes less predictable, and menstrual cycles often begin to change.
Perimenopause most commonly begins in the 40s and can last for several years. Symptoms may come and go or change throughout the transition.
Menopause is reached after 12 consecutive months without a menstrual period, as long as there is not another explanation. Until then, ovulation can still occur, even with irregular periods, which means pregnancy is still possible during perimenopause.
Perimenopause is usually a clinical diagnosis, based on your age, menstrual cycle changes, symptoms, and medical history. There is no single test that can definitively confirm whether you are in perimenopause.
Changes in your periods are often one of the first signs. Cycles may become shorter, longer, heavier, lighter, or more unpredictable. Other symptoms such as hot flashes, night sweats, sleep changes, mood changes, or vaginal dryness can also provide clues.
Hormone levels can fluctuate significantly during perimenopause, sometimes even from one day to the next. Because of this, a single FSH or estrogen level may be normal one day and different another day and generally cannot confirm or rule out perimenopause.
Hormonal birth control can also affect hormone levels and menstrual patterns, making hormone testing even more difficult to interpret.
Blood work may still be helpful in certain situations, particularly if symptoms occur at a younger age or if we need to evaluate for other possible causes of your symptoms, such as thyroid disease, anemia, or pregnancy.
Hormonal changes during perimenopause can affect many different parts of the body. Symptoms vary widely from person to person and may change throughout the transition. Some people experience only minor changes, while others have symptoms that significantly affect sleep, mood, work, relationships, or quality of life.
Changes in menstrual cycles are often one of the earliest signs of perimenopause. Periods may become closer together or farther apart, heavier or lighter, longer or shorter, or more unpredictable. Although changes in bleeding are common during perimenopause, new or abnormal bleeding should not automatically be assumed to be caused by hormonal changes. Talk with your doctor if you experience very heavy or prolonged bleeding, bleeding between periods, or other significant changes in your bleeding pattern.

Hot flashes and night sweats, sometimes called vasomotor symptoms, are among the most recognizable symptoms of the menopause transition. They can range from occasional warmth or flushing to frequent episodes that interfere with sleep and daily activities.
Changes in sleep, mood, memory, and concentration are also common during perimenopause. Some people experience difficulty sleeping, irritability, anxiety, mood changes, fatigue, forgetfulness, or “brain fog.” Sleep disruption from night sweats can make some of these symptoms worse.
Hormonal fluctuations can affect headaches and migraines. Some people notice that migraines become more frequent or change in pattern during perimenopause, particularly if they have previously experienced menstrual migraines.
Declining and fluctuating estrogen levels can contribute to vaginal dryness or irritation, discomfort with intercourse, urinary symptoms, and changes in sexual desire or function.
Perimenopause may also be accompanied by changes in hair and skin, weight, body composition, breast tenderness, joint or muscle symptoms, and other physical changes. Not every symptom that develops during midlife is necessarily caused by perimenopause, so new or concerning symptoms may still warrant evaluation for other causes.
The symptoms you experience during perimenopause are real and can have a significant impact on how you feel and function. At the same time, some symptoms can overlap with other health conditions, such as thyroid disease, anemia, or sleep disorders. Changes in menstrual bleeding are also common during perimenopause, but abnormal bleeding should not automatically be attributed to the menopause transition. Very heavy or prolonged bleeding, bleeding between periods, or other significant changes may require additional evaluation.
If your symptoms are unusual, severe, or changing, we may recommend additional evaluation to make sure we are addressing all of the factors that could be contributing to how you feel.
Treatment during perimenopause is individualized based on your symptoms, medical history, and personal preferences. Some people need little or no treatment, while others benefit significantly from treatment when symptoms begin affecting sleep, mood, work, relationships, or quality of life. There is no single “best” treatment. Options may include lifestyle changes, nonhormonal treatments, hormonal contraception, hormone replacement therapy, or a combination of approaches.
Regular physical activity, balanced nutrition, adequate sleep, stress management, and limiting alcohol and tobacco can support overall health during the menopause transition. Certain changes may also help with specific symptoms, although lifestyle measures alone may not be enough for everyone.

Hormone therapy is not the only option for managing perimenopausal symptoms. Several nonhormonal prescription medications can help, particularly with hot flashes and night sweats. The best option depends on your symptoms, other medications, medical history, and personal preferences. Options may include:
Certain antidepressants (SSRIs or SNRIs): Can reduce hot flashes and may be especially helpful when mood or anxiety symptoms are also present.
Gabapentin: Can reduce hot flashes and night sweats and may be particularly helpful when symptoms interfere with sleep.
Veozah® (fezolinetant): A nonhormonal medication specifically designed to treat moderate to severe hot flashes.
Lynkuet® (elinzanetant): A nonhormonal medication for moderate to severe hot flashes that may also help with sleep disturbance associated with menopause symptoms.
Over-the-Counter Options
Some people prefer to try an over-the-counter supplement. Estroven® is one commonly available option that I often recommend. Several formulations are available for different menopause-related symptoms. As a reminder, supplements do not work for everyone and are not regulated in the same way as prescription medications.
Birth control pills, patches, rings, hormonal IUDs, and other contraceptive methods can be particularly useful during perimenopause. Depending on the method, they may provide pregnancy prevention, regulate menstrual cycles, reduce heavy bleeding, and improve certain perimenopausal symptoms.

You do not have to wait until menopause to use hormone therapy. HRT can be used during perimenopause when appropriate and is particularly effective for symptoms such as hot flashes and night sweats. Treatment is individualized based on your symptoms, medical history, whether you still have a uterus, and your personal preferences.
Some symptoms may benefit from more targeted treatment. Vaginal or urinary symptoms, sexual concerns, migraines, abnormal bleeding, hair loss, mood symptoms, and sleep problems may each require a different approach. Treatment can be tailored to the symptoms that matter most to you.
Perimenopause is a natural transition and does not need to be treated unless your symptoms are bothersome to you. If changes in your periods, sleep, mood, relationships, sexual health, work, or overall quality of life are affecting how you feel or function, please reach out.
You do not need to wait until symptoms become severe to ask about treatment options. Depending on your symptoms, we may also recommend blood work or other evaluation to look for additional factors that could be contributing to how you feel.
