How to Support Someone with PMOS (Previously PCOS): A Guide for Partners, Family and Friends
If someone you love has PMOS (Polyendocrine Metabolic Ovarian Syndrome), previously known as PCOS, you may have heard them talk about irregular periods, exhaustion, cravings, hair growth, acne, difficulties with their weight or worries about fertility. What can be much harder to explain, particularly to someone who hasn't experienced it themselves, is what it actually feels like to live with the condition day to day.
PMOS isn't simply a period problem and, despite its previous name, it isn't really about having "cysts on your ovaries" either. It's a complex endocrine condition that can affect many different areas of someone's health and wellbeing, including their menstrual cycle, fertility, metabolic health, skin, hair, mood and energy levels.
Because so many of these symptoms aren't immediately visible, living with PMOS can sometimes feel incredibly lonely. If your partner, daughter, sister or friend has sent you this article, they probably aren't expecting you to fix the condition or suddenly become an expert in it. They may simply want you to understand a little more about what is happening in their body, how it can affect everyday life and what genuinely helpful support might look like.
What is PMOS (previously PCOS)?
PMOS stands for Polyendocrine Metabolic Ovarian Syndrome and is the new name for the condition previously known as Polycystic Ovary Syndrome, or PCOS. It is a common endocrine condition affecting around one in eight women and can affect reproductive, metabolic and psychological health.
The name was officially changed in May 2026 following an international consensus process involving people living with the condition alongside health professionals and organisations around the world. One of the reasons for the change was that "polycystic ovary syndrome" didn't accurately represent the condition and placed too much emphasis on the ovaries and so-called "cysts".
In reality, PMOS is much broader than this.
Symptoms vary considerably from one person to another. Someone might experience very irregular or absent periods, while another person struggles predominantly with acne, unwanted facial or body hair or hair loss. Other women experience fatigue, difficulties with weight, problems becoming pregnant or several symptoms at the same time.
This variation is important because two women can have the same diagnosis and experience it very differently, which also means there isn't one diet, supplement, medication or lifestyle change that will be right for everyone.
What does living with PMOS actually feel like?
This is often the part that is hardest to explain.
Many of the symptoms of PMOS aren't necessarily visible to the people around you, so someone can look perfectly well while privately dealing with symptoms that affect a significant part of their day.
You might not see the exhaustion that makes getting through an ordinary working day difficult, or the brain fog that can make concentrating on something that would normally be straightforward feel surprisingly hard. You may not realise that she's worried about the amount of hair coming out every time she washes it, while at the same time dealing with unwanted facial or body hair that she is constantly trying to hide.
You probably don't see the thoughts running through her mind when another month passes and her period still hasn't arrived, and you may have no idea that while everyone else is casually discussing babies, pregnancy or when they're going to start a family, she's sitting there wondering whether she'll be able to have one.
One of my clients described how, before getting the right support, she needed nine to ten hours' sleep during the week and sometimes eleven to twelve hours at weekends just to compensate. Alongside the fatigue, she was experiencing brain fog, irritability and hair shedding, all of which had gradually become part of her normal life.
Another client described feeling so overwhelmed by conflicting information about PMOS that even deciding what to have for dinner could become incredibly stressful.
These experiences won't apply to every woman with PMOS, but they give you an idea of how much the condition can spill over into ordinary life, often in ways that aren't obvious from the outside.
Why can PMOS affect energy, hunger and cravings?
This can be particularly difficult for friends and family to understand because hunger, cravings and tiredness can easily be interpreted as something a person should simply be able to control.
PMOS is associated with metabolic features including insulin resistance, although this doesn't affect every woman in exactly the same way. Insulin resistance
means the body's cells don't respond to insulin as effectively as they should, which can result in the body producing more insulin to compensate.
This is one of the reasons it's important not to reduce conversations about PMOS to willpower. The biology of the condition matters, and someone's experience of hunger, energy and food can be influenced by much more than motivation or discipline.
It is also worth remembering that fatigue can have many causes, even in someone with PMOS, so persistent or significant tiredness shouldn't automatically be attributed to the condition without appropriate medical assessment.
Food can become much more complicated than you realise
Women with PMOS are surrounded by advice about what they supposedly should and shouldn't eat, which means well-intentioned comments from family and friends can sometimes add to an already overwhelming amount of noise.
They may have been told to stop eating carbohydrates, give up sugar, cut out dairy or gluten, eat less, fast, lose weight or follow a particular "PCOS diet". When you're exposed to those messages repeatedly, eating can start to feel less like an ordinary part of life and more like a test you're constantly worried about failing.
I've worked with women who arrive genuinely frightened that everyday foods are making their condition worse, while others have spent years dieting, restricting food or feeling guilty whenever they eat something they believe they "shouldn't".
One of my clients described how, before we worked together, she felt as though she couldn't eat everyday foods such as carbohydrates, dairy or sugar because she had come to believe that managing PMOS required extreme diets and cutting out entire food groups. After making much smaller, more manageable changes, she described leaving behind much of that food noise and feeling more confident about how to nourish her body.
This is why comments such as "Should you be eating that?" are unlikely to be helpful, even when they come from a place of concern. The same applies to commenting on someone's weight or sending them the latest PMOS diet you've found online.
Nutrition and lifestyle are important parts of PMOS management, but that doesn't mean someone needs to follow a perfect diet or eliminate entire food groups. Good PMOS care should consider the individual, their symptoms and health needs, alongside factors such as nutrition, physical activity, sleep, emotional wellbeing and appropriate medical treatment.
Please don't assume she isn't trying hard enough
If someone with PMOS is struggling with their energy, cravings, eating, exercise or weight, it can be easy for people on the outside to assume that they simply need to be more disciplined. In my experience of working with women with PMOS, however, many have already spent years trying incredibly hard.
They've exercised more, eaten less, tracked their food, downloaded the apps, cut out foods they enjoy, bought supplements, read endless articles and repeatedly started another diet in the hope that this time it might finally work. When those approaches aren't sustainable or don't produce the results they were promised, they often end up blaming themselves.
PMOS isn't caused by laziness or a lack of willpower, and someone struggling with their symptoms doesn't necessarily need more pressure or another person holding them accountable. What can be much more helpful is appropriate medical care, reliable evidence-based information and support that helps them understand what is happening in their individual body.
How can PMOS affect mental health and body image?
PMOS can have a significant psychological impact, and this is something that deserves to be taken just as seriously as the physical symptoms. International evidence-based guidance highlights the high prevalence of psychological features associated with the condition and specifically recognises the importance of emotional wellbeing, quality of life and awareness of weight stigma.
When you consider some of the symptoms, it isn't difficult to understand why.
Living with acne as an adult can affect how comfortable someone feels in their skin, while losing hair from the scalp at the same time as growing darker hair on the face or body can be incredibly difficult emotionally. Changes in weight or body shape can be frustrating too, particularly when someone feels as though they're already putting enormous effort into looking after themselves.
When you add unpredictable periods, fertility worries, fatigue and years of being told to "just lose weight", the cumulative effect can be substantial.
This is also why immediately jumping into problem-solving mode isn't always what someone needs. If she tells you she's struggling, asking, "That sounds really difficult. Do you want me to listen, or would it be helpful to think through what you need?" gives her the opportunity to tell you what kind of support would actually feel useful.
How can you support a partner, friend or family member with PMOS?
You don't need to become a PMOS expert, and you certainly don't need to monitor what she's eating, remind her to exercise or take responsibility for managing her condition. The most helpful support is often much simpler than that.
Believe her when she tells you she's exhausted, struggling with cravings, worried about fertility or finding her symptoms difficult, even when you can't see what she's experiencing. Try asking what she needs rather than assuming, because sometimes she may want practical help while at other times she may simply want somebody to listen without immediately offering a solution.
It's also helpful to avoid policing her food or commenting on whether she "should" be eating bread, dessert, dairy or anything else. Even comments about weight that are intended as compliments can be difficult, particularly for someone who has spent years being taught that the size of her body is the most important measure of how well she is managing her condition.
Instead, think about how supportive habits can become part of ordinary life together. You might cook a satisfying dinner together, suggest going for a walk because it's a lovely evening rather than because she "needs to exercise", or recognise when she's exhausted and help create space for her to rest.
There is an important difference between supporting someone and supervising them, and most women with PMOS don't need another person checking whether they're doing everything "right".
It's also worth remembering that symptoms can fluctuate, so having a good week doesn't mean the condition has disappeared, just as having a difficult week doesn't mean she's done something wrong.
What should you avoid saying to someone with PMOS?
You don't need to worry about saying exactly the right thing all the time, but there are a few comments that can be particularly difficult to hear repeatedly.
Questions such as "Should you be eating that?", comments about needing to lose weight, comparisons with somebody else who has PMOS, or suggestions that she simply needs to exercise more can make someone feel as though the condition is their fault.
The same applies to fertility. If someone has told you they're worried about becoming pregnant, phrases such as "Just relax and it'll happen" or stories about somebody who became pregnant as soon as they stopped trying are unlikely to make that uncertainty easier.
Rather than trying to reassure someone out of what they're feeling, give them room to tell you what the experience is actually like for them.
What she probably wants you to understand
I've worked with many women with PMOS who come to me feeling overwhelmed, frustrated and disconnected from their bodies, and beneath the individual symptoms there is often a very simple wish: they want to feel like themselves again.
With appropriate, individualised support, some of my clients have described improvements in areas such as their energy, cravings and menstrual cycles, as well as feeling calmer and more confident around food. These are individual experiences rather than promises about what will happen for everyone, but some of the most meaningful changes they describe aren't necessarily the ones that can be measured on a blood test or a set of scales.
They begin to understand their bodies, feel less frightened of food and stop feeling as though they are constantly fighting against themselves.
One client described feeling "more positive and in control" of her PMOS after receiving support, while another talked about finally learning to understand what her body needed after years of trying to battle through misinformation.
Family and friends can play an important role in that process too, not by trying to fix PMOS or having all the answers, but by being willing to listen and understand.
If someone you love has PMOS, believe her when she tells you how she's feeling, ask what would genuinely help and try to be one less voice telling her what she should be doing with her body. Having someone in your corner who understands that this is a real and complex condition, rather than something you could solve if you simply tried a little harder, can make living with PMOS feel considerably less lonely.
Frequently asked questions about supporting someone with PMOS
Is PMOS the same as PCOS?
Yes. Polyendocrine Metabolic Ovarian Syndrome (PMOS) is the new name for the condition previously known as Polycystic Ovary Syndrome (PCOS). The terminology officially changed in May 2026 following an international consensus process. You will continue to see both terms while awareness of the new name develops.
Is PMOS just a problem with periods and ovaries?
No. Although irregular or absent periods and problems with ovulation are common features, PMOS is a broader endocrine condition that can affect reproductive, metabolic and psychological health. Symptoms can include acne, unwanted hair growth, hair loss, difficulties with weight, fatigue and difficulties becoming pregnant, although the experience varies considerably between individuals.
Why is someone with PMOS so tired?
Fatigue is reported by some women with PMOS and is now included among the symptoms described by the NHS. However, tiredness can have many different causes, so significant or persistent fatigue should be discussed with a healthcare professional rather than automatically assuming PMOS is responsible.
What is the best thing to say to someone struggling with PMOS?
You don't need to have the solution. Something as simple as, "I can see this is really difficult. Do you want me to listen, or is there something I can do to help?" allows the person experiencing it to tell you what they need.
Can PMOS be cured?
There is currently no cure for PMOS, but symptoms can be managed. The right approach will depend on the individual and may involve lifestyle support, medication and/or fertility treatment depending on their symptoms, health and priorities.
