PMOS Doctor in London
Irregular periods. Acne that keeps returning. Weight that feels unusually difficult to shift. Facial hair growth that affects confidence. Fatigue, brain fog, or a sense that your hormones are working against you.
For many women, this is where the PMOS story begins, although you may know it better as PCOS. The condition is now increasingly referred to as PMOS, a name that better reflects what is happening in the body: a hormonal and metabolic pattern that can affect ovulation, insulin sensitivity, skin, mood, fertility, and long-term health.
As a GP and functional medicine doctor based in central London, I take a more detailed view of PMOS / PCOS. I look beyond the ovaries alone and focus on the wider hormonal, metabolic, and inflammatory picture that may be driving symptoms.
I offer face-to-face consultations at Charterhouse Clinic in London W1, as well as video appointments for patients across the UK.
PMOS, previously known as PCOS
Many patients have heard the term PCOS, but not PMOS. PMOS is the newer name and is intended to reflect the condition more accurately, because it involves not only the ovaries, but also wider hormonal and metabolic changes.
What matters most is not the label itself, but understanding your individual pattern and what may be driving it.
When PMOS / PCOS symptoms begin to affect daily life
Symptoms vary widely, which is one reason the condition can be missed, misunderstood, or oversimplified.
Common symptoms include:
irregular, infrequent, or absent periods
difficulty losing weight, particularly around the abdomen
acne, especially around the jawline
excess facial or body hair
fatigue, low mood, or brain fog
fertility concerns or difficulty conceiving
Why conventional treatment often falls short
Many women are offered the contraceptive pill to regulate periods, and metformin if blood sugar or insulin issues are suspected.
Conventional treatment can be an important and appropriate part of PMOS care, and in some cases it can help with issues such as insulin resistance and symptom control. At the same time, it does not always explore the wider factors that may be driving the picture underneath, which is why a more joined-up approach can be helpful.
A functional medicine approach to PMOS / PCOS
In my practice, I begin by understanding your specific pattern. PMOS / PCOS is not one-size-fits-all, and the same label can reflect different underlying drivers in different women. I look closely at:
Insulin resistance, which is one of the most common metabolic drivers
Chronic inflammation, which can worsen hormone imbalance
Gut health and the microbiome, which influence hormone metabolism
HPA axis function, including how stress and cortisol affect your cycle
Thyroid health, which is often an overlooked contributing factor
What to expect in a consultation
A first functional medicine consultation is 60 minutes. Before we meet, I ask you to complete a detailed health questionnaire so we can use the time properly.
During the appointment, we review your symptoms, cycle history, fertility plans if relevant, skin changes, weight pattern, energy, previous test results, and the wider context of your health.
Where appropriate, I may recommend deeper investigation, such as hormone testing, metabolic markers, gut microbiome analysis, or other functional assessment to build a clearer picture.
From there, I create a personalised plan that may include nutritional changes, targeted supplements, lifestyle support, further investigation, and where needed, conventional medication.
PMOS / PCOS and fertility, weight, and metabolic health
This condition is not only about periods or ovarian appearance on a scan.
PMOS / PCOS can affect ovulation, fertility, insulin sensitivity, weight regulation, and long-term metabolic risk. That is why I take a broader view of the condition and why a plan needs to reflect more than one symptom at a time.
Why work with a PMOS doctor with a GP and functional medicine perspective
One advantage of this approach is that I am not looking at your symptoms in isolation or through a single specialist lens.
I work from a GP foundation, which means I can think clinically about testing, diagnosis, medication, referrals, and wider health context, while also using a functional medicine perspective to explore the root causes behind the hormonal and metabolic imbalance.
“I’ve been working with Dr. Tatyana for the past four months for my PCOS, and I truly couldn’t be happier with the care I’ve received. She listens so carefully and pays close attention to even the smallest details — and those small details have made a big difference in my progress.
Since starting treatment with her, I’ve seen significant improvements in my health and overall quality of life. I always feel heard, supported, and genuinely cared for during our appointments.
I highly recommend Dr. Tatyana to anyone looking for a knowledgeable, attentive, and compassionate doctor.”

Frequently asked questions
Is PMOS the same as PCOS?
1In current patient and search use, the terms are often used interchangeably. Many people still know the condition as PCOS, while some clinics now use PMOS wording to reflect the broader hormonal and metabolic nature of the syndrome.
Can PMOS / PCOS affect fertility?
2Yes. It can affect ovulation and cycle regularity, which is why fertility concerns are a common reason women seek support.
Is insulin resistance always part of PMOS / PCOS?
3Not always, but it is one of the most common underlying drivers and is important to assess, even in women who do not appear overweight.
What tests might be useful?
4That depends on your symptoms and history, but it may include hormone testing, metabolic markers, and other investigations that help clarify what is driving the pattern in your case.
Can you help if I have already been offered the pill or metformin?
5Yes. If you have already been given a standard treatment route but still want a more personalised, root-cause view of your symptoms, I can help review the wider picture.
Ready to take a different approach to PMOS / PCOS?
If your symptoms have been reduced to a label but never fully explained, a more detailed review can help you understand what is really driving the pattern.
