PCOS becomes PMOS: what does the new name mean?

Why has PCOS been renamed PMOS?

PCOS stood for polycystic ovary syndrome. This name could suggest that abnormalities in the ovaries are the primary feature, while hormones, ovulation, and metabolism also play significant roles.

This perspective is too narrow. Not everyone with this condition has noticeable cysts. Symptoms can also be linked to hormonal and metabolic processes, such as those affecting the menstrual cycle, skin, weight, fertility, and insulin sensitivity.

For this reason, the term PMOS was chosen: a name that better reflects the medical aspects of the condition.

What does PMOS mean?

PMOS stands for polyendocrine metabolic ovary syndrome. The name highlights that symptoms can be connected in multiple ways to hormones, metabolism, and the ovaries.

• Polyendocrine: multiple hormones may be involved.
• Metabolic: metabolism plays a role, for example, in how the body manages energy and insulin.
• Ovary: the ovaries can influence ovulation and menstruation.
• Syndrome: it refers to a combination of symptoms and characteristics.

PMOS is not a new condition. It is simply the new name for what was previously called PCOS. This does not automatically mean that your diagnosis or treatment will change.

PCOS and PMOS: what is the difference?

The main difference lies in the focus of the terms.

What symptoms can be associated with PCOS or PMOS?

Symptoms of PCOS or PMOS can differ greatly from one person to another. One individual might primarily notice irregular periods, while another could experience more pronounced issues with their skin, weight, or fertility.

Symptoms that may be linked to PMOS include:

• irregular periods;
• absence of periods;
• acne;
• excessive hair growth;
• hair thinning or hair loss;
• weight gain or difficulty losing weight;
• trouble conceiving.

It is important to note that these symptoms do not automatically indicate PMOS. They can also be caused by other conditions. A doctor can determine whether further investigation is necessary.

Does anything change regarding diagnosis or treatment?

No, not necessarily. If you have previously been diagnosed with PCOS, that medical information remains relevant.

However, the term PMOS can facilitate a more comprehensive discussion of symptoms. Beyond menstruation and fertility, it allows for consideration of skin concerns, weight, blood sugar levels, and insulin sensitivity.

The most suitable treatment will depend on your symptoms, overall health, and whether you wish to conceive.

When should you seek medical advice?

You should seek medical advice if your periods are frequently irregular, absent for an extended period, or if you experience symptoms that are difficult to explain. This also applies to acne, excessive hair growth, hair thinning or loss, weight gain, or fertility challenges in combination with menstrual irregularities.

A doctor can evaluate your symptoms in context, providing clarity about what may be happening and identifying the most appropriate course of action for your situation.

Conclusion

PMOS is the updated term for PCOS. For those with symptoms or an existing diagnosis, there are no immediate medical changes. However, the term PMOS allows for a broader discussion of symptoms, encompassing hormones, metabolism, skin, weight, and the menstrual cycle.
