1. What is Polyendocrine Metabolic Ovarian Syndrome (PMOS)?
Polyendocrine Metabolic Ovarian Syndrome, or PMOS, is a broader term sometimes used to describe the complex hormonal and metabolic features associated with Polycystic Ovary Syndrome (PCOS). It highlights that the condition affects not only the ovaries, but also metabolism, insulin regulation, and multiple hormone systems throughout the body.
2. How is PMOS different from PCOS?
PCOS traditionally focuses on reproductive symptoms such as irregular periods and ovarian cysts. PMOS emphasises the wider metabolic and endocrine effects of the condition, including insulin resistance, weight gain, inflammation, and increased cardiovascular risk.
3. What causes PMOS?
The exact cause is not fully understood, but it is believed to involve a combination of genetic factors, insulin resistance, hormonal imbalance, and environmental influences. Elevated insulin levels can stimulate excess androgen production, contributing to many symptoms.
4. What are the common symptoms of PMOS?
Symptoms may include irregular periods, difficulty ovulating, acne, excessive hair growth, scalp hair thinning, weight gain, fatigue, and difficulty losing weight. Some individuals may also experience mood changes or fertility challenges.
5. Does PMOS only affect the ovaries?
No. PMOS can affect multiple body systems. It is associated with insulin resistance, increased risk of type 2 diabetes, high cholesterol, fatty liver disease, sleep apnoea, and cardiovascular disease.
6. How is PMOS diagnosed?
Diagnosis is based on symptoms, physical examination, blood tests, and sometimes ultrasound imaging of the ovaries. Doctors also assess metabolic factors such as blood sugar, cholesterol levels, and signs of insulin resistance.
7. How is PMOS treated?
Treatment is individualised and may include lifestyle modification, weight management, exercise, dietary changes, hormonal treatments, and medications that improve insulin sensitivity. Fertility treatment may be considered if pregnancy is desired.
8. Can PMOS affect fertility?
Yes, irregular ovulation can make it more difficult to conceive. However, many individuals with PMOS are able to achieve pregnancy with lifestyle changes, medical treatment, or fertility support if needed.
9. Can PMOS improve over time?
Symptoms can improve with effective management, particularly through healthy lifestyle changes and weight reduction where appropriate. Long-term monitoring is important because metabolic risks may persist even if symptoms improve.
10. When should I see a doctor?
You should seek medical advice if you have irregular periods, signs of excess androgens such as acne or excess hair growth, difficulty conceiving, or symptoms suggestive of insulin resistance such as weight gain or fatigue. Early assessment can help reduce long-term complications.
