What Is PMOS?

Polyendocrine Metabolic Ovarian Syndrome (PMOS), previously known as Polycystic Ovary Syndrome (PCOS), is a common hormonal disorder affecting women. PMOS occurs when inappropriate hormonal signaling results in higher-than-normal androgen (male hormones) levels and other hormonal imbalances in a woman’s body. It is a complex disorder involving multiple systems, affecting the hormonal system, skin, metabolism, reproduction, and psychology. It can lead to a spectrum of abnormalities, including but not limited to absent or decreased menstruation, acne, growth of unwanted hair on the body, hair loss, multiple cysts in the ovaries, and infertility. Hence, PCOS was renamed.

PMOS can happen at any age, beginning from puberty and even up to menopause. The exact cause of PMOS is unknown. So, how do doctors actually diagnose PMOS? The international evidence-based guideline states diagnosis in adult women requires two of three criteria after excluding other disorders:

  • Hyperandrogenism (higher-than-normal male hormones).

  • Irregularity or absence of release of eggs from the ovaries.

  • Polycystic ovaries or elevated AMH (anti-Mullerian hormone).

When Should a Woman Seek Help?

A woman should consult a doctor if she notices the following:

  • Very little flow of blood in periods or months of altogether absent periods.

  • Acne, hair loss, and excessive facial or body hair.

  • Having problems conceiving.

  • Family history of PMOS.

  • If an ultrasound ever shows a polycystic ovarian pattern.

  • Darkening of the skin at the nape of the neck, below the breasts, or in the armpits.

However, you should also keep in mind that not every woman with PMOS will have the same symptoms. Some women may have only irregular periods, while others may suffer from skin, weight, or fertility issues first. This can cause confusion and lead to late diagnosis of PMOS.

What Are the Effects of PMOS on Women’s Bodies?

Other than the visible changes related to appearance, irregular periods, and infertility (difficulty getting pregnant), there are many other long-term consequences associated with PMOS. It is a condition that should not be ignored, as its effects may slowly impact overall health over time.

Regrettably, many doctors also do not see beyond treating the immediate symptoms of infertility in these women.

1. When ignored, women with PMOS may develop metabolic syndrome (a group of health problems that occur together), which includes

  • High blood pressure.

  • High blood sugar levels.

  • Abnormal cholesterol or triglyceride levels (an increase in unhealthy fat levels in the blood).

These conditions significantly increase the risk of developing heart disease in the future.

2. There is also a chance of developing steatohepatitis (fat-related inflammation of the liver) caused by fat accumulation in the liver. Women who become pregnant with PMOS are at higher risk of:

  • Miscarriages.

  • Pregnancy-induced high blood pressure.

  • Gestational diabetes (diabetes during pregnancy).

  • Premature birth (baby born too early).

3. The condition is often complicated by being overweight, though lean patients with PMOS are also not uncommon. Overweight women with PMOS may also suffer from sleep apnea (a condition in which breathing repeatedly stops during sleep), which can manifest as

  • Snoring.

  • Fatigue (extreme tiredness).

  • Excessive daytime sleepiness.

4. Most overweight PMOS girls also struggle with body image issues (feeling unhappy or insecure about appearance), and some may develop depression. Many girls may also develop eating disorders (unhealthy eating habits), resulting in a cycle of overeating and further weight gain.

5. Unfortunately, the risks do not end here. Women with PMOS also have nearly a twofold increase in the risk of cancer of the uterine lining, known as endometrial cancer (cancer of the inner lining of the womb). This happens because of less frequent periods. Normally, the inner lining of the uterus is shed during every menstrual cycle, but in the absence of regular periods, the lining keeps growing without being shed properly.

What Are the Common Myths About PMOS?

There are many misconceptions about PMOS that can cause unnecessary fear and confusion. Let us separate myths from medical facts. You may have heard some of these statements before. Get ready to know the scientific facts about those myths.

1. PMOS Is Diagnosed on Ultrasound Only

No. It is a systemic disease and not just a disease of the ovaries. Even without having polycystic ovaries on ultrasound, one may be diagnosed with PMOS based on clinical evidence and blood tests.

2. One Cannot Get Pregnant if They Have PMOS

Though PMOS is a common cause of infertility, one can still get pregnant either naturally or with fertility treatments. Always seek early advice from a gynecologist when planning for a baby. Most of the time, simple ovulation-induction drugs help the patients in achieving pregnancy, though IUI (intrauterine insemination) or IVF (in vitro fertilization) may be required too.

3. If One Does Not Want to Conceive, They Do Not Need to Treat PMOS

As discussed, PMOS has a long-term impact on the health of women. Getting diagnosed and treated is critical for a healthy life. One must seek medical help not only for treatment but also for preventive check-ups to diagnose other associated ailments like diabetes, lipid abnormalities, and even malignancy as early as possible.

4. Everyone With PMOS Is Overweight

Not everyone! Though most women with PMOS are overweight or frankly obese, thinner women may also have PMOS and should not be overlooked.

5. Women with PMOS cannot Lose Weight Easily

There is no concrete scientific evidence suggesting that PMOS women cannot lose weight. Healthy living and losing just 5 % of one’s body weight can have immeasurable long-term benefits.

6. PMOS Is a Hopeless Disease

While it is true that there is no magic cure for PMOS, it indeed is treatable. Acne, hair loss, menstrual irregularities, and infertility can all be treated. Long-term complications like diabetes, heart disease, high blood pressure, lipid abnormalities, and cancer can be prevented or controlled.

What Are the Lifestyle Changes That Can Help in PMOS?

Small, consistent lifestyle changes often can make a bigger difference than extreme diets. PMOS is manageable, and these lifestyle changes make a major difference. The goal here is not perfection but to develop long-term healthy habits.

  • Maintain a healthy lifestyle.

  • Try to lose weight, even if it is as low as 5% of the total body weight.

  • Maintain an ideal weight.

  • Eat healthily and eat on time. Watch out for emotional eating.

  • Do not consume foods with very high sugar and/or fat content.

  • Sleep for at least eight hours a day.

  • Avoid smoking and reduce alcohol consumption.

  • Doing some kind of physical activity for a minimum of 2.5 hours or 150 minutes a week is needed for maintaining an ideal weight. Physical activity may include walking, cycling, swimming, household chores, sports, or planned exercise.

Conclusion

PMOS (previously called PCOS) is a common condition that can affect your periods and cause other symptoms. Changes in daily habits and medical treatments can help control the symptoms, reduce the risk of other health problems, and improve the chances of getting pregnant. Between the myths and the realities lies the critical step of scrutiny and assessment by qualified personnel. So, if one suspects they have any symptoms of PMOS, consult a women’s health specialist for the accurate diagnosis and management of this condition. If you are living with PMOS, do not ignore regular follow-ups.

Key Takeaways:

  • PMOS, which was previously called PCOS, is not just a disorder of periods or ovaries. It can affect the whole body, including skin, weight, mood, and fertility.

  • The symptoms can be irregular periods, acne, hair fall, unwanted facial hair, or sudden weight gain.

  • PMOS is not only seen in obese women; even thin girls and women can have PMOS.

  • PMOS may make getting pregnant difficult for some women, but they still can become pregnant with the right treatment and care.

  • Women suffering from PMOS should develop healthy habits like regular exercise, good sleep, and balanced eating.
