Since May 2026, a new name has been appearing in health news across Malaysia: PMOS. Searches for “pcos pmos” and “pcos vs pmos” have shot up as women ask whether PMOS is a new disease and what PCOS really is. If you have typed “apa itu PCOS”, “maksud PCOS” or “PCOS itu apa” into a search bar, you are far from alone.
This article explains what polycystic ovary syndrome (PCOS) is, why it has been renamed, its possible signs, its long-term health links and everyday habits that help. It is general health education, not a substitute for talking to a doctor.
Apa Itu PCOS? (What Is PCOS?)
PCOS is a common, long-term hormonal and metabolic condition. Despite its name, it is not simply an “ovary problem” or a matter of “cysts”. The small sacs sometimes seen on the ovaries are immature egg follicles, not abnormal cysts, and many women with the condition do not have them at all.
Underneath is a mix of hormone changes. The body may make more androgens (“male-type” hormones all women have in small amounts), and many women have some insulin resistance. Together, these can affect periods, skin, hair, weight, mood and long-term health.
The team behind the new name estimates the condition affects about one in eight women worldwide, and the World Health Organization notes that many women with it have never been diagnosed. It tends to run in families, often shows itself from the teenage years, and is not caused by anything a woman did wrong.
PCOS vs PMOS: Why the Name Is Changing
In May 2026, a global consensus published in the medical journal The Lancet, led by Monash University in Australia, announced the new name polyendocrine metabolic ovarian syndrome (PMOS). It followed 14 years of global work with researchers, doctors and patient groups.
- Polyendocrine: several hormone (endocrine) systems are involved.
- Metabolic: the condition affects how the body handles energy and sugar.
- Ovarian: the ovaries are part of the picture, but not the whole story.
The old name pointed people towards “cysts”, yet research has found no increase in abnormal cysts in this condition. That focus is thought to have delayed recognition and hidden the metabolic and mental health side.
The switch is happening over about three years, with the new name expected in the 2028 international guideline, so both names will be seen in Malaysia for a while. They describe the same condition.
Tanda PCOS (Signs of PCOS): What It Can Look Like
PCOS symptoms vary from one woman to another and can change over the years. Signs women describe can include irregular or absent periods, persistent acne, extra hair growth on the face or body, thinning scalp hair, weight changes, and low mood or anxiety.
None of these tells a woman that she has PCOS. The same changes are also linked with stress, thyroid conditions and other hormone conditions, so only a doctor can assess the cause. This guide on when to see a doctor about women’s health concerns explains more.
Insulin Resistance, Diabetes Risk, Heart Health and Mood
Insulin is a hormone that helps sugar from food move out of the blood and into cells for energy. In insulin resistance, the cells respond less well, so the body makes more insulin to do the same job. Many women with PCOS have some insulin resistance, whatever their body size.
Higher insulin levels can push the ovaries to make more androgens, feeding into irregular periods, acne and extra hair. They also make the body more inclined to store fat, especially around the waist. This is why weight can feel harder to manage with PCOS: a hormonal effect, not a lack of willpower.
Over time, PCOS is linked with a higher risk of type 2 diabetes, diabetes during pregnancy, raised blood pressure and cholesterol changes that affect heart health. Not every woman develops these. Anxiety, depression and low body image are also more common and deserve the same attention as physical symptoms.
Everyday Habits That Support Hormonal and Metabolic Health
Habits do not make PCOS disappear, but in line with general MOH Malaysia and WHO advice, they support insulin use, energy, mood and heart health:
- Balanced meals: the Malaysian “suku-suku separuh” plate, with half vegetables and fruit, a quarter wholegrains and a quarter protein such as fish, eggs, tofu or dhal.
- Fewer sugary drinks: teh tarik, bubble tea and soft drinks add sugar quickly. Plain water, “kurang manis” or “kosong” are easy swaps.
- Moving most days: brisk walking, cycling or dancing, plus some muscle-strengthening activity.
- Sleep and stress: poor sleep and ongoing stress affect hormones and appetite.
- Not smoking, and keeping alcohol low.
For women carrying extra weight, even a modest loss can ease some symptoms. Small changes you can keep up matter more than strict diets.
Fertility, When to See a Doctor and Red Flags
Because ovulation may happen less often with PCOS, conceiving can take longer for some women, but many do conceive. If you are planning a pregnancy and have concerns, a doctor can advise and, where needed, refer you to a specialist.
It is sensible to see a doctor if your periods are irregular or have stopped and you are not pregnant, or if skin, hair, weight or mood changes trouble you. Women in Silibin and the wider Ipoh area can speak with a GP at the walk-in GP clinic in Silibin, Ipoh, who may refer onwards when specialist input is needed. As hormones shift later in life, some women also find it useful to read about menopause, its usual age and signs.
Red flag: sudden, severe pain in the pelvis or lower abdomen, especially with fainting, dizziness or vomiting, is an emergency. Go to the nearest emergency department or call 999. The same applies to any thoughts of harming yourself.
Frequently Asked Questions
Apa itu PCOS dan PMOS? (What are PCOS and PMOS?)
They are the same condition. PMOS, short for polyendocrine metabolic ovarian syndrome, is the new name for PCOS, announced in May 2026. The old name is being phased out gradually, so both terms will be seen for some time.
Maksud PCOS: what does PCOS actually mean?
PCOS stands for polycystic ovary syndrome. “Polycystic” means “many cysts”, which causes confusion, because the small sacs seen in some women are immature egg follicles. “Syndrome” means a group of features that occur together. PMOS better reflects the hormonal and metabolic nature of the condition.
Kenapa PCOS susah turun berat badan? (Why is it harder to lose weight with PCOS?)
Insulin resistance plays a large part, making the body store fat more readily. Poor sleep and low mood can add to this. Effort is not wasted: steady eating patterns, fewer sugary drinks and regular activity still support health, even when the scale moves slowly.
Can PCOS cause diabetes?
PCOS does not mean a woman will definitely develop diabetes, but it is linked with a higher risk of type 2 diabetes, especially alongside extra weight or a family history. Healthy habits and regular conversations with a doctor help keep this risk in view.
Does PCOS go away?
PCOS is usually a long-term condition rather than something that goes away. Its features often change across life, and many women find symptoms easier to live with through steady habits and ongoing support from a doctor. The metabolic side stays worth watching, including after menopause.
