Menopause is a natural stage of life, not an illness. It is the point when your ovaries stop releasing eggs and your periods come to an end. Officially, you have reached menopause once you have gone 12 months in a row without a period.
Most women reach menopause around age 51; however, for many women, the journey begins years earlier during perimenopause, when hormone levels start to fluctuate. During this transition, changes in estrogen and progesterone can cause a wide variety of symptoms that differ from one woman to another.
While menopause is a normal biological process rather than a disease, its symptoms can significantly affect quality of life. The years leading up to it, and the years after, each bring their own changes, and both are worth understanding. Understanding these hormonal changes can help women and their healthcare providers make informed decisions about symptom management, long-term health, and overall well-being.

The Three Stages
Scroll the table horizontally to compare all columns.
Stage |
What Is Happening |
|---|---|
Perimenopause |
The transition leading up to menopause, often starting in your forties and lasting several years. Hormone levels rise and fall unevenly, so periods become irregular and symptoms come and go. |
Menopause |
The point marked by 12 months without a period. It is identified looking back, once that year has passed. At this point, the ovaries have greatly reduced estrogen production and ovulation has ended. |
Postmenopause |
All the years afterward. Although some symptoms improve over time, lower estrogen levels continue to influence bone health, cardiovascular health, and other aspects of long-term wellness. |
If your periods stop before age 40, that is a different condition called primary ovarian insufficiency (POI), which needs prompt evaluation. Between 40 and 44, it is usually called early menopause.
Common Signs and Symptoms
Every woman's experience is different. Some have few symptoms; others find them disruptive. Common ones include:
- Hot flashes and night sweats
- Irregular periods, then periods stopping
- Fatigue
- Trouble sleeping
- Vaginal dryness or discomfort during sex
- Decreased sexual desire
- Needing to pass urine more often
- Mood changes, irritability, or low mood
- Brain fog or difficulty concentrating or remembering things
- Joint aches, changes in weight, or thinning hair
Symptoms can begin well before your periods stop, and they can continue for some years afterward. They are real, they are common, and there are effective ways to manage them.
What Causes Menopause?
Menopause occurs as the ovaries naturally produce fewer hormones over time.
As estrogen and progesterone levels decline, the brain signals the ovaries to work harder by increasing production of follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
Because hormone levels fluctuate considerably during perimenopause, symptoms may come and go before eventually becoming more consistent.
How Is Menopause Diagnosed?
This surprises many women: if you are over 45 and having typical symptoms along with changes to your periods, menopause is usually diagnosed from your symptoms and cycle history alone. Blood tests are generally not needed to confirm it, because hormone levels swing so much from day to day during this time that a single result can be misleading.
Blood testing is genuinely useful in specific situations, and your doctor will know when it applies:
- If you are under 45 and your periods have become irregular or stopped, testing helps identify early menopause or POI.
- If your symptoms could have another cause. Thyroid conditions in particular can look very similar to menopause, and are easily checked and treated.
- If you are thinking about hormone therapy, to establish your baseline health picture beforehand.
- To check on your longer-term health, such as bone, heart, and metabolic markers, which is where testing offers the most lasting value.
Why Laboratory Testing Matters
Although menopause itself is usually diagnosed clinically, laboratory testing can provide valuable information in selected situations. Depending on your symptoms and medical history, your healthcare provider may recommend testing that includes:
- Follicle-stimulating hormone (FSH)
- Luteinizing hormone (LH)
- Estradiol
- Thyroid function tests
- Pregnancy testing when appropriate
- Additional hormone testing based on your clinical presentation
Laboratory testing may also help evaluate other conditions that can produce symptoms similar to menopause, such as thyroid disorders or primary ovarian insufficiency.
MDL’s Menopause and Hormone Therapy Panels
MDL offers three panels in this area. Your doctor will choose the one that fits where you are and what you are deciding.
Comprehensive Menopause Panel. The fullest picture of your health through the menopause transition and beyond:
- Hormones - estradiol and estrone, FSH, LH, progesterone, testosterone, and SHBG.
- Thyroid - TSH, Free T4, and thyroid antibodies, since thyroid conditions can mimic menopause.
- Bone health - vitamin D, calcium, and markers that show how quickly bone is being renewed.
- Heart and metabolic - cholesterol, blood sugar, HbA1c, and an inflammation marker.
- Nutritional - iron, ferritin, and vitamin B12.
HRT Hormonal Panel. A focused hormone profile, for when you and your doctor need hormone levels alone - whether you are weighing up hormone therapy or already on it:
- The estrogens- estradiol, estrone, and estriol. These can behave differently depending on whether your therapy is taken by mouth or through the skin.
- Progesterone, testosterone, and DHEA-S - along with SHBG, a protein that affects how your hormones circulate.
- FSH, LH, AMH, and pregnenolone - completing the hormone picture.
Comprehensive HRT Panel. Everything in the hormonal panel, plus the wider health picture that matters when starting or continuing hormone therapy:
- Thyroid, cholesterol, blood sugar, and HbA1c - your baseline before you begin, and a way to follow changes over time.
- Inflammation and homocysteine - markers related to cardiovascular health.
Nutritional markers - iron, ferritin, folate, vitamin B12, and vitamin D
Which tests do you need? That depends on your age, your symptoms, and your plans. Your healthcare provider can order what fits your situation
Your Health After Menopause
Estrogen does more than manage your cycle. It also helps protect your bones and supports heart and metabolic health. As levels fall, a few areas deserve ongoing attention and this is where knowing your numbers genuinely helps.
- Bone health. Bone loss speeds up in the years right after menopause, raising the risk of osteoporosis and fractures later on.
- Heart and metabolic health. Cholesterol, blood sugar, and blood pressure often shift after menopause, so cardiovascular risk becomes more important to track.
- Thyroid health. Thyroid problems are common in midlife women and share many symptoms with menopause.
Alongside testing, the everyday basics matter: weight-bearing exercise and strength work, enough calcium and vitamin D, not smoking, limiting alcohol, and a balanced diet.
Hormone Therapy and How Testing Fits In
Hormone therapy, often called HRT, is one of the most effective treatments for menopause symptoms such as hot flushes and night sweats, and it can also help protect bone health. Whether it is right for you depends on your symptoms, your medical history, and your own preferences, a decision to make together with your doctor.
In November 2025, the FDA updated the safety labeling on menopausal hormone therapy products to better reflect current evidence, including age-specific guidance. If you have questions about what this means for you, your healthcare provider is the right person to ask.
MDL does not prescribe or recommend hormone therapy. What we provide is the laboratory information your doctor uses to establish your baseline before you begin, and to monitor the things worth watching while you are on treatment.
Treatment Options
Treatment depends on your symptoms, overall health, and personal preferences. Your healthcare provider may recommend:
- Lifestyle modifications
- Hormone therapy when appropriate
- Non-hormonal medications
- Vaginal estrogen or other local therapies when indicated
- Nutrition and exercise strategies
- Sleep management
- Stress reduction techniques
Treatment plans should be individualized and reviewed regularly as symptoms and health needs change.
Living Well Through Menopause
Menopause represents a new stage of life rather than the end of good health.
Understanding the changes taking place in your body, maintaining regular medical care, staying physically active, eating a balanced diet, and discussing symptoms openly with your healthcare provider can help you navigate this transition with confidence.
Many women find that with appropriate support and individualized care, they continue to lead healthy, active, and fulfilling lives after menopause.
