The Diagnosis Problem
5 healthcare professionals. That's the average number people with PMDD have to see before they are able to get a diagnosis (1).
In a recent study exploring healthcare experiences of women with PMDD across 9 countries, one participant recounted a gynaecologist who'd never heard of PMDD, and a psychiatrist who told her flatly "PMDD is not a real diagnosis" (2). This is one example of many that will make your jaw drop.
PMDD has been left out of diagnostic manuals, medical school syllabi, and most GPs' heads. It doesn’t even have its own information page on the NHS website - it’s mentioned as an afterthought on the PMS page, with some inaccurate symptoms listed. Instead of support, PMDD warriors are met with resistance, dismissal, and misattribution - forced to become researchers and experts in their own condition just to be heard.
Below, we’ve summed up the research on this long road to diagnosis, and how it impacts people living with it.
PMDD “An Inner War”
PMDD isn't well known to people generally, either. Too often we're told it's normal - "just part of being a woman". But PMDD is an intense and negative abnormal reaction in the brain to shifting hormones, with a complex biological basis that can significantly impair function. A recent paper defined PMDD as disabling (3).
Exploring experiences of having PMDD, women described it like this:
→ An inner war: a rollercoaster of negative emotions that fluctuate without warning, alongside rapid mood swings, sadness, and despair
→ Snapped in two: some describe their PMDD as an "alter ego" - a monster living within them
→ Searching for peace: feeling alone, desperate for somewhere to escape to
A 2025 Canadian study interviewed PMDD and asked them to describe what the luteal phase actually feels like. Almost everyone reached for the same image: a heavy, foggy, suffocating cloud (4).
Medical Gaslighting and Misdiagnosis
Women experiencing PMDD often don't get the chance to be listened to, understood, or properly diagnosed, leading to confusion and a chronic lack of support.
→ 54% of those with PMDD were medically gaslit before their diagnosis
→ 56% were misdiagnosed with another condition (including depression, anxiety, bipolar disorder and personality disorders)
→ 51% said their healthcare professionals had poor PMDD awareness
In the UK, most people see a GP before any specialist. For those with PMDD, 73% see a GP first (1). In a recent study, GPs significantly underperformed relative to gynaecologists - rating substantially lower on basic awareness of PMDD, knowledge of available treatment options and understanding of treatment efficacy (5).
Why are Doctors Finding it so Hard to Diagnose PMDD?
It’s been reported that only 10% of medical professionals feel confident diagnosing PMDD (IAPMD,6). On top of the outright dismissal and medical gaslighting, something is clearly going wrong at the training and systems level. Three structural reasons stand out:
1. Healthcare provider ignorance to the tools that exist to diagnose PMDD
The tools exist and they’re not being used. Diagnosis requires daily symptom tracking across two full menstrual cycles using a tool called the Daily Record of Severity of Problems (DRSP) - so the cyclical pattern and severity is undeniable. Without that, PMDD can be mistaken for something else - depression, anxiety, or bipolar disorder.
And yet research shows only 19% of those ultimately diagnosed with PMDD were diagnosed using the correct method - meaning the overwhelming majority of doctors simply aren't using it. (1).
2. It has two homes in medicine
DSM-V classifies PMDD as a depressive disorder whereas the ICD-11 classifies it as a gynaecological disease (7). The two major diagnostic manuals fundamentally disagree on where PMDD belongs - which can be confusing for patients and doctors, and results in specialists not knowing which domain PMDD diagnosis falls into. As a result, those with PMDD are passed back and forth between mental health and gynaecological services, with neither side taking full ownership.
3. PMDD has only just started being recognised
PMDD was formally recognised as a distinct diagnosable condition in 2013. Most GPs practising today were trained before then.
Put together, estimates put the average time to accurate PMDD diagnosis and treatment at 12-20 years (3).
None of this excuses the dismissal or the misattribution. But it partly explains why the system keeps failing people and why self-advocacy, daily tracking, knowing the criteria yourself, and staying informed about research updates have become survival skills for a PMDD warrior, not a nice-to-have.
Why Diagnosis is Worth the Fight
Despite everything it takes to get there, most women described the eventual diagnosis as deeply validating (8)
"Pure relief... I wasn't going crazy.”
1. Validation: difficult healthcare experiences finally felt worth it - struggles were acknowledged
2. Self-understanding: people could make sense of past experiences and improve their psychological wellbeing
3. Relief: frustration dissipates, and the healing journey can begin
4. Support: diagnosis opens the door to accommodations from family, workplaces, and schools - though formal support structures like this are still rare in many countries
Diagnosis is Not the Finish Line
One participant reported that diagnosis changed nothing because no support or treatment infrastructure existed around it - and she’s not alone. This is the next hurdle: diagnosis is not the finish line, because what comes after matters just as much.
Currently, first line medical treatments for PMDD are inconsistent in their effects -while they can be life changing for some, others are left disappointed.
1. A meta analysis of 9 studies found that while hormonal contraceptives can help with overall premenstrual symptoms, they are not found to reduce premenstrual depressive symptoms specifically, which is one of the main debilitating symptoms of PMDD (9)
2. A meta analysis of 34 studies found SSRIs fail for 39% with PMDD, and come with unwanted side effects (10)
3. In a meta-analysis of 11 studies GnRH agonists (without hormone add-back) are effective for PMDD, but the trade off is distressing menopause symptoms and bone mineral density loss. Because of this, add back hormones are then often prescribed, but these have conflicting results in PMDD, with some studies reporting they make PMDD symptoms worse (11)
Even among people who did get an official diagnosis, the Canadian study found that around 90% of participants had not found substantive, sustainable relief through treatment (4).
PMDD is complex - for most people it's rarely one solution, but a journey of finding what works for them individually, it may be combining medical and more holistic approaches. That reality needs to be better recognised and supported within healthcare settings too.
The takeaway
None of this is a reflection of you. A five-provider odyssey, a "vague medical interview" instead of a real diagnostic tool, a psychiatrist who thinks it isn't a real diagnosis - these are failures of training and systems, not signs that your symptoms are too confusing, too dramatic, or too hard to explain.
Right now, two things can shift this: knowledge and awareness. Feeling informed about navigating PMDD and staying current with research and guidance is a powerful tool through a system that hasn't caught up yet. Awareness - in healthcare settings and beyond - is what moves the system itself over time. These are the two things we focus on at DITTO, and why this research gets covered here: the more it's understood, the harder it becomes to turn the next PMDD warrior away.
A diagnosis isn't just a name, it’s validation. It can open the door to proper treatment and the opportunity to trial management options, and crucially, it can also help with reasonable adjustments, relieving some of the burden that PMDD carries. We know the situation is still far below what it should be, but we’re hopeful things are starting to change.
