Polyendocrine Metabolic Ovarian Syndrome (PMOS), formerly known as Polycystic Ovary Syndrome (PCOS), is one of the most common hormonal conditions affecting women of reproductive age. Although the name has changed to better reflect the condition’s impact on the entire body—not just the ovaries—the symptoms and underlying condition remain the same. PMOS is a complex endocrine and metabolic disorder that can affect menstrual cycles, fertility, hormone balance, metabolism, skin health, and long-term wellness.
At the The Endometriosis Treatment Center of America, we understand that many patients experience overlapping conditions. PMOS and endometriosis are separate disorders, but they can occur together, making diagnosis and treatment more challenging. Our team takes a comprehensive approach to evaluating your symptoms and developing an individualized care plan.
What Is PMOS?
PMOS occurs when the body’s hormone signaling becomes disrupted, leading to irregular ovulation and increased production of androgens (often called “male hormones”). Many patients also experience insulin resistance, which can contribute to metabolic changes and increase the risk of diabetes and cardiovascular disease over time. The updated name recognizes that PMOS is a whole-body condition involving endocrine, metabolic, and reproductive health—not simply ovarian cysts.
Symptoms of PMOS
Symptoms vary from person to person and may include:
- Irregular or absent menstrual periods
- Difficulty becoming pregnant due to irregular ovulation
- Acne or oily skin
- Excess facial or body hair (hirsutism)
- Thinning hair or hair loss on the scalp
- Weight gain or difficulty losing weight
- Insulin resistance or prediabetes
- Fatigue
- Mood changes
- Darkened areas of skin (acanthosis nigricans)
Not every patient experiences every symptom, and severity can vary significantly.
PMOS vs. Endometriosis
Although PMOS and endometriosis both affect reproductive health, they are very different conditions.
- PMOS is primarily a hormonal and metabolic disorder that often causes irregular ovulation and infertility.
- Endometriosis occurs when tissue similar to the uterine lining grows outside the uterus, causing inflammation, scarring, chronic pelvic pain, and infertility.
Some women have both conditions simultaneously. When this occurs, symptoms can overlap, making evaluation by an experienced specialist especially important.
How PMOS Is Diagnosed
There is no single test for PMOS. Diagnosis typically includes:
- Comprehensive medical history
- Review of menstrual patterns and symptoms
- Physical examination
- Blood work to evaluate hormone levels and metabolic health
- Pelvic ultrasound when appropriate
Healthcare providers generally diagnose PMOS using established clinical criteria after excluding other hormonal disorders.
Treatment Options
Treatment depends on your symptoms, health goals, and whether pregnancy is desired. Your personalized treatment plan may include:
- Lifestyle and nutritional counseling
- Weight management strategies
- Medications to improve insulin resistance
- Hormonal therapies to regulate menstrual cycles
- Fertility treatments when appropriate
- Management of acne, hair growth, or other hormonal symptoms
- Ongoing monitoring for metabolic health
Our goal is to help improve both immediate symptoms and long-term health.
When Endometriosis and PMOS Occur Together
Many patients come to us after years of unexplained pelvic pain, irregular cycles, or infertility. While PMOS may explain irregular ovulation, it does not typically cause the severe pelvic pain associated with endometriosis. Likewise, endometriosis does not cause the hormonal imbalances seen with PMOS. Because both conditions can coexist, a thorough evaluation is essential to ensure that every contributing factor is identified and appropriately treated.
Why Choose the Endometriosis Treatment Center of America?
At the The Endometriosis Treatment Center of America, we recognize that pelvic pain, infertility, and hormonal disorders are rarely one-size-fits-all. Our specialists provide comprehensive evaluations to determine whether your symptoms are related to endometriosis, PMOS, or another gynecologic condition. By looking at the complete picture, we can develop a personalized treatment plan focused on improving your quality of life, preserving fertility when desired, and helping you achieve long-term health and wellness.
