Perimenopause is the transition before menopause, when estrogen and progesterone rise and fall unpredictably. It usually begins in a woman's 40s, sometimes in the mid-to-late 30s, and lasts about four years on average, though it can run longer. At Sky Women's Health in Fort Worth, Dr. Carolyn Moyers, a Menopause Society Certified Practitioner, diagnoses and treats perimenopause based on your symptoms, not just your lab results.

Symptoms vary widely, and many women do not connect them to hormones at first. Common signs include:
Periods that become irregular, heavier, lighter or closer together
Hot flashes or night sweats, sometimes only around your period
Trouble falling or staying asleep
New anxiety, irritability, rage or low mood
Brain fog and forgetfulness
Worse PMS, breast tenderness or migraines
Lower sex drive or vaginal dryness
Weight gain around the middle
Fatigue and joint aches
If you are over 35 and your cycle, sleep or mood has changed without a clear reason, perimenopause is a strong possibility. Many women are told their labs are normal because hormone levels can look fine on the day of the test. Dr. Moyers looks at the full picture, including your age, cycle pattern, symptoms and health history, and uses labs to rule out other causes such as thyroid disease or anemia.
| Perimenopause | Menopause | |
|---|---|---|
| When it happens | Usually starts in the 40s; can begin in the mid-to-late 30s | Average age 51 in the U.S. |
| Periods | Still happening, but often irregular | None for 12 months in a row |
| Hormones | Estrogen and progesterone swing up and down | Estrogen and progesterone stay low |
| How it is diagnosed | Symptoms and cycle changes; labs are often inconclusive | 12 months without a period |
| Pregnancy | Still possible; use contraception if you want to avoid pregnancy | Not possible once menopause is confirmed |
| Treatment options | Low-dose hormone therapy, progesterone, hormonal IUD or birth control, non-hormonal and lifestyle options | Hormone therapy, non-hormonal and lifestyle options |
Hormone therapy: low-dose estrogen and progesterone to steady symptoms. See hormone replacement therapy.
Progesterone: can help with sleep and with heavy or irregular bleeding.
Hormonal IUD or birth control: controls heavy or unpredictable bleeding and prevents pregnancy.
Non-hormonal medication: options for hot flashes, sleep and mood when hormones are not right for you.
Lifestyle medicine: nutrition, strength training, sleep and stress plans, plus medical weight loss for midlife weight gain.
Sexual health care: treatment for low libido and painful sex. See women's sexual health.
Book a visit if symptoms are affecting your sleep, work, mood or relationships. See a doctor promptly for bleeding that soaks through a pad or tampon every hour for several hours, periods less than 21 days apart, bleeding after sex, or any bleeding after 12 months without a period, as these need evaluation.
Dr. Moyers holds the MSCP credential from The Menopause Society and has two decades of clinical experience.

Most women notice perimenopause in their 40s, but it can begin in the mid-to-late 30s. It ends 12 months after your final period, which happens at an average age of 51.
Perimenopause lasts about four years on average, but it can range from a few months to ten years.
Not reliably. FSH and estrogen levels change from day to day during perimenopause, so a single test can look normal even when symptoms are hormonal. Diagnosis is based mainly on your age, symptoms and cycle changes.
Yes. Ovulation becomes irregular but does not stop, so you need contraception until menopause is confirmed if you want to avoid pregnancy.
For most healthy women, yes. Low-dose hormone therapy or hormonal contraception can be used in perimenopause, and Dr. Moyers reviews your health history, blood clot risk and breast cancer risk before recommending a treatment.
Yes. Consultations and follow-ups can be done by video for patients located in Texas. If you need a pelvic exam, ultrasound or in-office labs, we schedule that at our Fort Worth clinic.
