You’ve been told your labs are normal. You’re still not well.

For women with PCOS, PMS, PMDD, and perimenopause who are tired of being dismissed by conventional medicine and overwhelmed by the wellness industry, there’s a better way.

You’re not imagining it.

PCOS • PMS • PMDD • Endometriosis • Perimenopause • Menopause • Burnout • Weight Concerns • Fertility

Sound familiar?

You’ve done the research. You’ve tracked the symptoms. You’ve tried gluten-free, dairy-free, keto, and every supplement the internet recommended. You’ve been to your doctor and she told you your labs are fine, maybe try the pill, or come back when you want to get pregnant.

Meanwhile you’re exhausted, your clothes don’t fit the way they used to, your mood shifts feel like a different person takes over every month, and you’re scrolling at 11pm trying to figure out why nothing has worked.

You don’t need another supplement list. You don’t need another restrictive diet. You need someone who will actually take the time to figure out what’s going on and then help you do something about it.

Hi, I’m Dr. Kate.

I’m a hormone-focused Naturopathic Doctor, and I’ve built my practice in the space between two extremes . The “test nothing, do nothing” culture of conventional medicine and the “test everything, do everything perfectly” culture of the wellness industry.

I use targeted lab work through LifeLabs not $500 functional panels. I prescribe 1–2 supplements when they’re helpful and not a cabinet full. I build treatment plans around how you actually eat, move, sleep, and manage stress. And when conventional options like HRT or medication are the best tool for the job, I recommend them without apology.

I also live with PCOS and PMDD, so I’m not just someone who studied this. I’ve been in it.

PCOS & Hormonal Health — Naturopathic Doctor Waterloo ON | Dr. Kate Ferguson

How I work is different.

A one-hour initial intake to hear your full story, your symptoms, your history — and targeted lab work to get real answers. Not the kitchen-sink approach. Not “your labs are fine.”

We start with understanding.

Nutrition, movement, sleep, and stress management are the foundation — not supplements. Your plan is built for your real life, not a perfect week.

We build a plan that actually fits your life.

This isn’t a one-and-done appointment. Most patients see me 5 times in their first year — because the patients who have more touchpoints get better results.

We stay in it together.

Two ways to get started.

1:1 Comprehensive Care

For women with PCOS, PMS, PMDD, perimenopause, endometriosis, burnout, or weight concerns who want a practitioner who takes the time, orders the right tests, and builds a plan specific to them.

Yes- I do go for my mammograms.

I get asked this all the time in practice- well “do you go for mammograms?” My answer before was not yet- but I will. I’m 34 but with some concerns we found I went early and I’ll keep going as needed as part of my care plan.

Is having your boobs squished like a pancake a fun way to start the day? No.

Is it as “sexy” as taking the supplements, eating the fibre, and lifting the weights? No.

Is it shown to prevent mortality from breast cancer and that the benefits of screening outweigh the risks? Yes.

It’s absolutely every persons choice whether they go for their screenings or not- but you deserve to access accurate information on the benefits and risks for YOU personally. Be sure to chat with your provider about what screenings are most indicated for you.

PSA to book that pap or mammogram you’ve been putting off- you owe it to yourself.

Hint: it’s not the coffee, it’s that I LOVE coffee

Once a week I come to work a bit earlier than usual. I give myself some space to breathe. I get a few admin tasks done as I normally would, and then I pause. I pause and I walk down the street to the local coffee shop and I get myself an iced latte. Yes, I can make coffee at home… but something about going to the coffee shop and having that little treat for myself brings me joy.

Joy- that’s the key. When we’re managing PMS and PMDD injecting joy into your day is essential. Not mindfulness or meditation (those can be there too), but joy.

I always have my patients make a list of things they love on their phone, sort them into time categories (5 min, 15 min, 30 min, 1 hour plus) and set the goal of doing at least one thing off that list daily.

For me my 15 min coffee shop habit, brings my pure joy. It’s not about the coffee, it’s that the coffee brings me joy. Joy is what helps us build resistance with our hormonal health, so the monthly shifts start to feel a little more and more manageable each month.

Your PMS or PMDD journey isn’t just about the supplements you take, it’s tactical coaching that’s customized to your life to help you build that resilience. Your AI bot can’t do that ;), and this is where the magic happens.

That inflamed and puffy feeling is often coming from poor recovery. If your muscles don’t have enough fuel to recover they feel “inflamed”, you might carry more water weight as your body tries to recover from the exercise stimulus.

So often when I see women trying to change their body composition they are under fuelling during the week, exercising at a high intensity, and then making up their fueling gaps in the evenings or weekends. This pattern leaves your body under recovered and under fuelled for the exercise you’re doing - hello water retention feeling.

It’s the coolest thing when I finally convince them to eat more during the day and suddenly they are recovering better, and actually building the muscle they are striving for.

Food is your friend, and so is high intensity exercise 🤍

I say this with love… and clinical experience 😌

Most of us don’t need:
🚫another supplement
🚫another restrictive diet
🚫another “hormone balancing protocol” we found on “cyclesynchinggirlie37”s instagram

You need:
✅a plan that is rooted in science (not trends or fluff)
✅a routine you can actually follow
and someone to call you out (kindly) when if feels like it’s not working
✅A real human there to guide you and keep you on the right path (not an AI robot- sorry chat)

The problem isn’t that nothing works, it’s usually that nothing has been given enough time to work (or you’ve had the wrong information all together). It’s usually right after those moments you want to quit, that things start working.

I get it! You’ve been feeling overwhelmed and dismissed, all while being given conflicting advice and trying to piece this together on your own.
Of course you feel stuck!

If you’re ready to stop starting over every 2 weeks…and actually see progress

I’m here 🤍

When health optimization becomes the enemy of imperfect consistency

Hot take:

Your health is probably not being held back by a lack of information.

It’s being held back by trying to execute a plan that is way more complicated than it needs to be.

What if you just go for the walk, go to bed, eat breakfast, or go to the gym?

You can optimize it later.

Right now, you probably just need to do the thing 🤍

In an online space where everyone has an opinion on what worked for them and their PMOS (PCOS), it can be hard to know who to trust.

Sharing what works for them, is not the same as understanding the science backed assessment and treatment options for a condition. Helping themselves doesn’t mean they have the skills to strategize, and coach you towards success.

Having PMOS doesn’t make me qualified to help you worth yours. 8 years of studying health, 1000s of research papers, continually evolving my clinical skills to translate science into action for you, and working with 1000s of other patients to understand nuances of women’s health…
That does 🤍

I get it...the supplement feels easier because it’s the lower barrier to entry. It’s sold to you as the fix. One scoop a day and suddenly your hormones, energy, PMS, sleep, weight, and mood are all supposed to magically improve.

Meanwhile, you’re still missing work because of your symptoms.
Still dealing with PMS, hot flashes, exhaustion, anxiety, or feeling like you don’t even recognize yourself.

You’re stuck bouncing from plan to plan trying to figure out what’s actually wrong because nobody has taken the time to properly assess you, run the lab work, or create a targeted plan for you.

This cycle costs women so much time, energy, money, and quality of life than the initial appointment ever would.

A proper assessment and science-backed plan is an investment, not an expense. In fact 99.9% of the time, it saves you money (and suffering) in the long run. 🤍

Let’s do it together 🤍, I got you!

Dancing into your appointment like helloooo it’s me, no longer anemic and ready to take on the world.

Iron deficiency is no joke, and it’s so often misdiagnosed or missed in women.

Here are some signs that make us want to check your iron 🤍
•fatigue
•shortness of breath
•anxiety
•poor exercise recovery
•thinning hair
•heavy periods
•restless legs
•cold hands and feet
•intolerance to cold

It’s amazing what women are capable of when we correct their iron deficiency! Whether it’s finding the right form of supplement or getting an iron infusion, we are here to help! 🤍

Disclaimer: these opinions are solely my own, and based on the best available science ;)

Tired of the “you’re fine” attitude of our public system, and “do everything perfectly” culture of the wellness industry? Me too.
Welcome to the ideal middle where we use science to help you feel like yourself again, but better 🤍. (I promise there won’t be any 14 step morning routines).

DM me READY to learn more about how we can make sure you’re supported

If you’re a woman in your 30s or 40s trying to understand your hormones, you’ve probably realized everyone has a wildly different opinion about what the hell is actually happening and what to do about it.

On one side, you’re told your blood work is “normal,” you’re probably too young for perimenopause, and maybe an SSRI is your only option.

On the other side, the wellness industry is telling you that everyone needs HRT, a perfectly balanced nervous system, and a 14-step morning routine just to survive.

The truth is usually somewhere in the middle.

You deserve a proper, comprehensive assessment and a science-backed plan that’s built for your body and your life. One that helps you feel better without making you feel overwhelmed in the process. This phase of life isn’t all doom and gloom, with the right support and a willingness to shift what works now- these can be your best years yet.

Tackling your hormonal health shouldn’t feel this confusing — and you deserve to feel like yourself again (or maybe even better). 🤍

Which one are you?

Everyone experiences the different shifts in their hormones differently. Some people feel amazing on cycle day 1, when they ovulate, or a few days before their period starts— while these same phases can come along with horrible symptoms for others.
We don’t currently think the levels of hormones that cause the symptoms, we think it’s your brains reaction to the change and how it processes it.

The only kind of “cycle syncing” you need is to learn how your body reacts to each shift lean into your strengths for that phase.
Cycle day 1 for me is highly productive, but I still want quiet time (and some treats).

I’m so curious, How do you feel on cycle day 1? Comment the emoji that best describes your day 1 mood and we can see all the variations!

We play with monster trucks and hot wheels (his favourite things) and then we go to the coffee shop for a little treat (my favourite thing).

The number reason I hear women give for not doing things they enjoy and things that light them up is... kids.

But what if we found a way to include our kids in those things?

Here are some of my favourite things that bring me joy that we do together
•coffee shop (obvi)
•walking
•hiking
•listening to music
•colouring
•hot tubbing lol
•swimming

It doesn’t have to be parenting vs fueling your sense of yourself, you can have both 🤍

HRT is just a tool, it’s not the solve 🤍

Actually all the people showing up the gym every single morning - are busy people doing really cool things. They don’t have more time than everyone else, or a special schedule that allows them to spend more time exercising (okay maybe the retirees do ;))— they see that time at the gym as an investment.

An investment into their mood, energy, longevity, patience with others, and their health. It’s not “an hour they could have been doing something else”, it’s the hour they invest so that THEY CAN DO everything else.

The biggest barrier I hear to exercise is time, but if it matters you need to make the time. Do it with your kids, do it with them there, do it on your lunch break, do it early in the morning… just do it. You can do the things, I know you can 🤍

PCOS is now PMOS: Polyendocrine Metabolic Ovarian Syndrome.

Here is my unfiltered opinion

I’m excited because PCOS has been misunderstood for YEARS as simply being a condition of “cysts on the ovaries”, but this condition is so much bigger than cysts (and you can have PMOS with or without cysts on your ovaries).

PMOS (PCOS) impacts metabolism, insulin resistance, mood, fertility, heart health, and long-term health in ways the old name never fully captured. That’s why this new name matters! The new name actually reflects the scope of what we are dealing with and starts to highlight other aspects we need to support better in medicine.

How we name a condition shapes how we think about it, how we diagnose it, how we research it, and ultimately, how we treat it.

For way too long, PCOS has been treated like it starts and ends with fertility, we slapped birth control on it and said “come back when you want to get pregnant”. All while so many women were left unsupported in the metabolic, mental health, and other aspects of this condition.

The 10% pissed off part is just that it took this long for us to think about this condition differently.

Women have been dismissed, missed in the diagnostic criteria, underdiagnosed, overdiagnosed, and told their symptoms were “normal” for YEARS.

This is a huge part of what fuels the work I do every day.

Overall, I do think this is a huge step in the right direction. I’m still very aware that changing the name is the easy part. Now we need the care to catch up too. 🤍

If you’re ready to stop chasing quick fixes and find out what works for YOU, I’m here to help 🤍

Motherhood is beautiful.
It is also physical labour, emotional labour, mental labour, invisible labour, that needs support.

Somewhere along the way, so many women were taught that being a “good mother” means putting themselves last and abandoning the version of themselves they knew before becoming a mother. Pushing through exhaustion, giving up their own dreams, ignoring their own needs, and carrying everything quietly.

Thriving in motherhood was never supposed to come from self-sacrifice.

You need support, rest, nourishment, and time to chase after your goals or doing what lights you up outside being a mother.

You need time for yourself, movement that makes you feel strong, healthcare providers who listen, and relationships where you’re cared for too.

Taking care of yourself does not make you selfish.
It makes you a better mother 🤍

I hope you get spoiled today and take a bit of this energy into the days ahead!

And to the women for whom today feels heavy, the women navigating infertility, pregnancy loss, grief, complicated relationships, or the ache of wanting motherhood and not knowing what the future holds, I see you too. Sending you an abundance of love today 🤍

This idea came up in a book I just read “Unhinged Habits” and it really stuck with me. Why do we always put work first and fill everything else in the blank space? Why do we cancel our plans with friends and family when work is more demanding?

What if we filled in our family time, social time, movement, and leisure time first, and then the work around that?

What would look different?

I saw a Naturopathic Doctor in my 20s that told me I had to give up coffee for my “adrenal fatigue”. There’s no more to the story because I only saw her once. 🙈

Coffee is not the problem, and adrenal fatigue isn’t actually a thing. Chronic stress, underfueling, crap sleep, not moving your body enough, overtraining- those are problems my friend- and that’s what we need to focus on.

Welcome to my little corner of the internet where we focus on real science backed support for your hormonal health, and call the BS what it is, BS.

I promise I won’t take away your little cup of joy, or your gluten (unless you’re allergic).

🤍

Terrifying 💀

Impossible to pick just 5 when it comes to women’s health.
6 would be IUD insertion without pain meds 💀

What’s yours?

If you don’t believe you can achieve it — you likely never will.

The biggest difference between women I work with that achieve their goals, and those that stay stuck, is that those that find success believe they can.

They believe they hold the power to reduce their PMDD symptoms.
They believe that the way they experience perimenopause or menopause is in their power to change.
They believe they can change their body composition.
They believe they can sleep better.
They believe they can get their cycles back with pcos.

If you don’t believe you can, or that you deserve better, you are not going to tolerate the turbulence and challenge it requires of you to get better.

Healing (or learning to do a double under 😂) is not a linear journey. It’s always going to have ups, downs, setbacks, and quantum leaps forward. If you believe you can, you’ll do everything in your power to stick to the plan when things get hard (like whipping yourself a million times with the rope), you won’t give up, and that my friends is the secret sauce to success with your health.

Which version of me do you get today? 👼 😈

Real talk though:
Shout out to my husband who is the most patient soul on the planet.
I’m constantly working on myself to shrink the PMDD window where I become an unrecognizable version of myself. All while he accepts me where I’m at and supports me with what I need. The combination of grace and growth are what keeps us working as a team. It’s us vs PMDD, not me vs him.

PMDD isn’t just “PMS”, it can derail you’re entire life for 1-2 weeks before your period each month. With a multifaceted and personalized approach the way you experience PMDD can improve drastically. What used to be 2 weeks of me turning off from the world has shrunk to 2-4 days most months. It’s an ongoing journey, but it CAN be better with the right support in place 🤍

Testosterone has been shown to help with sexual function and libido in those with hypoactive sexual desire, but all the other claims on testosterone have yet to be supported in the research.

Many online menopause Doctors or influencers are claiming that testosterone supports pelvic floor health, mood, and energy levels... but we have yet to see this established.

Testosterone isn’t without risk either- it can cause acne, irregular hair growth, and potentially increase the risk for heart disease.

As always, you deserve a conversation about what is right for YOU, and testosterone may be, but it’s definitely not something everyone needs to be taking. 🤍

Are you confused about perimenopause and hormone replacement? You’re not alone, DM me READY to explore how we can tackle this phase together!

I once wrote a scathing reply to a school wide email from the head of Clinical Operations at Naturopathic College that I didn’t appreciate the tone of his email and that he should be more considerate of how it may be received by students. (I’m not sure his “tone” was the problem, I think I was 🙈). Cue cycle day one the next day and it all makes sense. Ooopsies.

Now your turn! 👇

“You have PCOS, this means you’ll likely not be able to have children” she said to me with one butt check on the stool and one hand on the door handle waiting to exit the room.

“Any questions?”

Umm only a million!

But I said “no” and ran to my car to ball my eyes out. I was 17 at the time and spent the next 14 years thinking it just might not be possible to me to be a mom.

We struggled to get pregnant, but in the end we were able to conceive our little miracle dude naturally.

I’ll never forget those words that day in my Doctors office and they are what fuel my fire to make that experience different for any other woman diagnosed with PCOS.

PCOS does not mean infertility! The challenges PCOS can pose to fertility are in a spectrum and there is SO MUCH you can do to support what that looks like for you.

If you’ve ever had a similar story, I’m sorry, and I’m here to let you know it can be different 🤍 I see you, and I’m here for you!

What other questions do you have about HRT? Help me help you 🤍

If you want a personalized discussion around HRT and YOU, I’m here. This is one of my favourite things I get to do with women in my office everyday!

Iron deficiency is an epidemic in women!
If you’re struggling with fatigue and you haven’t had your iron checked recently... we should check that for you!

Iron deficiency makes everything hard, and life doesn’t need to feel that way.

The upleveling that happens for my patients who are struggling with their iron levels when they finally get an Iron infusion is incredible! Someone actually told me they feel like they have superpowers now! It’s the coolest thing to see!

Let’s check your ferritin girl 🤍

Just a girl with PCOS and all her favourite things

Your perfect PCOS plan doesn’t need to involve a laundry list of supplements and a hardcore restrictive diet. It needs to be built on effective and repeatable foundations that YOU can do consistently.
Your plan will look different than mine, and that’s the magic of customized science backed care 🤍
