Feeling sluggish? Mood changes? Irregular or missed periods? Some of these changes may be due to perimenopause. Before women experience the “Big Change,” they often report feeling a million little changes related to the gradual decline in hormones before menopause.
Perimenopause is a natural stage of life, but that doesn’t mean you have to navigate it alone or feel unsure about what’s happening in your body. At Moreland OB-GYN, we help women across Waukesha County find relief as they transition into perimenopause through personalized care.
Below, we break down what perimenopause is, what symptoms to expect, how it’s diagnosed, and how to find the right doctor to guide you through it.
What is Perimenopause?
Perimenopause is the transitional phase before menopause when estrogen levels begin to decline. During this time, your ovaries still release eggs, which means pregnancy is still possible, but shifting hormones can trigger a wide range of physical and emotional symptoms.
The hormonal changes during perimenopause are largely driven by declining estrogen, a hormone that plays a key role in regulating your reproductive system. Progesterone levels also decline. Rather than dropping steadily, these hormone levels often fluctuate, which is why many symptoms can feel inconsistent or sudden.
In the later stages of perimenopause, estrogen levels drop more significantly as your body moves closer to menopause. Once you have gone 12 consecutive months without a menstrual period, menopause is reached—at which point ovulation stops, periods end, and pregnancy is no longer possible.

How Long Does Perimenopause Last?
Perimenopause lasts an average of about four years, but it can range from just a few months to as long as eight to 10 years.
Perimenopause is a highly individualized journey — the length of this transition varies from person to person. Some women experience only mild symptoms for a short time, while others may have a longer, more gradual transition with more noticeable changes. Factors like hormone patterns, overall health, and lifestyle can all influence how long perimenopause lasts.

What Age Does Perimenopause Typically Start?
Perimenopause typically begins in a woman’s mid-40s, but it can start earlier,sometimes as early as the late 30s. This transition usually begins about eight to 10 years before menopause. In some cases, menopause may occur before age 40, which is considered premature menopause. When this happens without a medical or surgical cause, it may be diagnosed as primary ovarian insufficiency.
What Are the Signs and Symptoms of Perimenopause?
The most common indication of perimenopause is a change in your menstrual cycle. Some women report longer-than-normal cycles, while others report that their cycles have become shorter. During this time, you may begin to skip periods and your menstrual flow may become lighter or heavier.
Other signs and symptoms of perimenopause include:
- Hot Flashes — A sudden sensation of heat that rushes to your upper body and face that lasts anywhere from a few seconds to a few minutes or longer. Some women experience hot flashes a few times each month, while others have them several times each day. Hot flashes that occur at night, also called “night sweats,” may even wake you up at night and prevent you from falling back to sleep.
- Difficulty Sleeping — In addition to the possibility of waking up at night from hot flashes, some women experience difficulty falling asleep or staying asleep through the night.
- Mood Swings and More Intense Premenstrual Syndrome (PMS) — Fluctuations in hormones cause many women to experience stronger and more frequent mood swings. You may also experience more intense PMS, even if you haven’t previously been affected by it.
- Vaginal Dryness and/or Discomfort During Sex — As estrogen levels decrease, the lining of the vagina often becomes thinner, drier and less elastic, all of which can cause pain during sex.
- Urinary Tract Changes — A decline in estrogen may also cause the urethra to become dry, inflamed, or irritated, resulting in a more frequent and urgent need to urinate and an increased risk of urinary tract infections.
Do Changes to Your Menstrual Cycle Always Mean You Are in Perimenopause?
No, changes to your menstrual cycle do not always mean you are in perimenopause.
While irregular periods are one of the most common signs of perimenopause, they can also be caused by other health conditions, hormonal imbalances, or underlying conditions that require medical attention.
You should talk to your OB-GYN if you experience any of the following symptoms, as they may indicate a need for additional evaluation:
-
Periods that seem inappropriately heavy
-
Periods that last much longer than usual
-
Spotting between periods or after sex

Can Perimenopause Impact Your Mental Health?
Yes, perimenopause can impact your mental health due to hormonal fluctuations that affect mood-regulating chemicals in the brain.
As estrogen levels rise and fall unpredictably, many women experience changes in how they feel emotionally and mentally. Estrogen plays a role in regulating neurotransmitters like serotonin, which influences mood, sleep, and overall well-being. A change in hormone levels can lead to symptoms such as:
-
Increased anxiety
-
Mood swings or irritability
-
Feelings of depression
-
Brain fog or difficulty concentrating
-
Trouble sleeping
For some women, these symptoms may feel mild and manageable, while for others, they can significantly impact daily life.
It’s important to know that you’re not alone—and you don’t have to simply “push through” these changes. Support is available through personalized treatment plans designed around your needs, including lifestyle adjustments, counseling, and medical therapies.
How Do I Know If I Am Perimenopausal?
Perimenopause is typically diagnosed based on your symptoms, age, and menstrual history.
Because hormone levels fluctuate daily, a single blood test is not always definitive. Instead, your provider may use a combination of:
-
Symptom evaluation
-
Medical history
-
Hormone testing in select cases
What Type of Doctor Can Help with Perimenopause?
While some women may also seek care from primary care providers or endocrinologists, an OB-GYN is often the best place to start to help diagnose and manage perimenopause.
Because perimenopause is driven by hormonal changes that affect your reproductive system, OB-GYNs are specially trained to recognize symptoms, evaluate hormone-related concerns, and recommend both hormonal and non-hormonal treatment options. They can also help rule out other conditions that may mimic perimenopause, such as thyroid disorders or uterine abnormalities.
At Moreland OB-GYN, our team includes four Menopause Society Certified Practitioners (MSCPs)—providers with advanced training in menopause and midlife hormonal health. This specialized expertise allows us to create personalized treatment plans tailored to your symptoms, health history, and goals.
What Treatment Options Can a Doctor Provide for Perimenopause?
A doctor can help manage perimenopause symptoms through a range of personalized treatment options, including both hormonal and non-hormonal approaches.
Because every woman’s experience with perimenopause is different, treatment is not one-size-fits-all. Your provider will consider your symptoms, medical history, and personal preferences when recommending the right plan for you.
Hormonal treatment options may include:
-
Hormone therapy: Estrogen therapy helps relieve hot flashes, night sweats, and vaginal dryness. If you have a uterus, you will also need progesterone to counteract the effects of estrogen on the lining of the uterus.
-
Low-dose birth control pills to regulate periods and reduce symptoms
Non-hormonal treatment options may include:
-
Medications to help manage hot flashes or mood changes
-
Vaginal moisturizers or lubricants for dryness and discomfort
-
Support for sleep disturbances or anxiety
In addition to medical treatments, your doctor may also recommend lifestyle adjustments and preventive care strategies to support your overall health during this transition.
Working with a knowledgeable provider ensures that your symptoms are properly evaluated and that you have safe, effective options to help you feel your best.
Is There Anything I Can Do to Alleviate the Symptoms?
Yes, there are several lifestyle changes you can make to help manage perimenopause symptoms and support your overall well-being.
While medical treatments can play an important role, daily habits and routines can also have a meaningful impact on how you feel during this transition. Focusing on your overall health has been shown to help reduce the severity of many common perimenopause symptoms.
Here are a few ways you can support your body:
-
Stay active by beginning or continuing a regular exercise routine
-
Maintain a healthy weight to support hormone balance and overall health
-
Prioritize sleep by going to bed and waking up at the same time each day
-
Support your nutrition with a balanced diet, including adequate calcium and vitamins
-
Quit smoking, which can worsen symptoms and impact long-term health
-
Manage stress through relaxation techniques, mindfulness, or other coping strategies
-
Limit alcohol intake, which may help reduce symptoms like sleep disturbances and hot flashes
It’s easy to dismiss the signs of perimenopause as stress or a busy lifestyle, since these symptoms often feel similar. However, small, consistent changes can make a meaningful difference in how you feel day to day.
It’s Never Too Early to Prioritize Your Health
Perimenopause doesn’t start overnight—and neither should your care.
Because this transition can begin years before menopause, establishing care early allows you to better understand your body, track changes, and address symptoms before they begin to disrupt your daily life. Proactive, preventive healthcare can help you manage not only hormonal symptoms, but also support your long-term health, including your bone health, heart health, and overall well-being.
At Moreland OB-GYN, we encourage women to start the conversation early. Our team of Menopause Society Certified Practitioners (MSCPs) can guide you through every stage of perimenopause with personalized care and evidence-based treatment options.
If you’re entering your mid-to-late 30s or 40s and starting to notice changes, now is the time to take a proactive approach.
