Note: Polycystic Ovarian Syndrome (PCOS) has officially been renamed Polyendocrine Metabolic Ovarian Syndrome (PMOS) to better reflect the condition’s metabolic and endocrine nature. Throughout this article, you’ll see both names used to help women find the information they need during this transition. Read why the name changed here.
The PMOS & Perimenopause Connection
Many women are surprised to discover that the symptoms of perimenopause and Polyendocrine Metabolic Ovarian Syndrome (PMOS), formerly known as Polycystic Ovarian Syndrome (PCOS), can look remarkably similar.
Abdominal weight gain, chin hair growth, scalp hair thinning, mood swings, insomnia, and irregular menstrual cycles are common in both conditions. While they occur for different reasons, they share one important hormonal characteristic: androgen dominance.
During perimenopause and menopause, estrogen levels naturally decline. With little estrogen available to balance the effects of androgens, many women begin experiencing symptoms commonly associated with elevated male hormones.
For women with PMOS (formerly PCOS), androgen levels are often already elevated. Even when estrogen levels are normal, the overall hormone balance remains androgen dominant, leading to many of the same symptoms seen during the menopausal transition.
Every Woman's PMOS and Perimenopause Journey Is Different
How a woman with PMOS experiences perimenopause varies greatly from person to person. This is why a personalized treatment plan is so important.
Traditional Hormone Replacement Therapy (HRT) is often designed for women without PMOS and may not adequately address the unique hormonal balance seen in women living with the condition.
For example, some menopausal women without PMOS may benefit from a small dose of testosterone as part of their HRT regimen. However, this approach is generally not appropriate for women with PMOS who already have elevated androgen levels.
Instead, treatment should be carefully tailored to your individual hormone profile, symptoms, and long-term health risks.
PMOS Treatment Doesn't End at Perimenopause
Although reproductive hormones change during menopause, PMOS treatment doesn’t stop, it evolves.
Women with PMOS have an approximately 19% higher risk of cardiovascular events compared to women without the condition.
As women approach menopause, healthcare providers may recommend transitioning from combined oral contraceptives to a lower-dose bioidentical estradiol patch commonly used in hormone replacement therapy, particularly if a patient develops:
- Uncontrolled high blood pressure
- A history of blood clots
- Other contraindications to estrogen-containing birth control
Because bioidentical estradiol provides less androgen suppression than birth control pills, additional medications may be needed to continue treating symptoms such as:
If you still have an intact uterus, progesterone remains an essential part of treatment to reduce the risk of endometrial (uterine) cancer.
Additional Health Considerations During Perimenopause
As estrogen declines, many women notice increased abdominal weight gain. For women with PMOS, treatment goals may shift toward improving metabolic health through medications such as:
- GLP-1 receptor agonists
- Metformin
Sleep also becomes an increasingly important focus.
Insomnia and obstructive sleep apnea often worsen during perimenopause. In some cases, progesterone dosing may need adjustment, or your provider may recommend a sleep study.
Research also shows that women with PMOS have a higher risk of developing sleep apnea after age 35, regardless of obesity status.
How Do You Know If You've Reached Menopause While Taking Birth Control?
Many women with PMOS ask an important question:
“If birth control has already stopped my menstrual cycle, how will I know when I’ve reached menopause?”
The answer isn’t always straightforward.
Determining menopause while taking hormonal birth control often requires temporarily stopping oral contraceptives and anti-androgen medications so your healthcare provider can evaluate your body’s natural hormone production.
During this time, blood work, including Follicle Stimulating Hormone (FSH) levels, is typically performed on two separate occasions several months apart.
Because your PMOS medications are paused during testing, many women experience a temporary return or flare of their symptoms.
For this reason, providers usually wait until menopause is strongly suspected before beginning this evaluation.
Many clinicians begin discussing menopause testing around age 50, although there is no universal timeline. By age 55, approximately 90% of women have naturally reached menopause.
Why Regular PMOS Care Matters Throughout Your Life
PMOS is a lifelong condition, and your treatment plan should change as your body changes.
Regular evaluations with a PMOS / PCOS Specialist become especially important during perimenopause to ensure your treatment continues supporting your hormonal, metabolic, and cardiovascular health.
It’s especially important to reassess your care if you develop:
- Uncontrolled high blood pressure
- Cardiovascular disease
- Blood clots
- Migraine with aura
- New or worsening symptoms during perimenopause
A personalized treatment plan can help you navigate this transition safely while continuing to manage the symptoms of PMOS.
