Dr. Dominique Vanier, ND *Accepting new patients in-person and virtually Ontario-wide*

Hi! I’m Dr. Dominique.

I help patients with digestion and hormone issues no longer worry about bathroom access and avoiding certain foods, and have easy and pain-free periods. Using naturopathic medicine and natural health solutions to bring the body back into balance.

I'm looking forward to another season of speaking at conferences and CE events! It's always a privilege to connect with colleagues, discuss the latest research in digestive health, and share practical strategies that can be applied in clinical practice.

Hope to see some familiar faces along the way!

Understanding the *actual* mechanisms behind your digestive symptoms is what leads to treatments that work.

40. Thankful to have made it this far. Excited that this decade will be even better than the last. My thirties marked me becoming a naturopathic doctor, a big move to our first home, starting my own business, and my proudest accomplishments - the birth of my two kids.

I’m grateful for the people who have shared this ride with me ❤️

Constipation is more than just not going to the bathroom often.

It can show up as bloating, abdominal pain, reflux, nausea, straining, or feeling like you never fully empty. And it can affect anyone—from babies and toddlers to adults.

The causes can be surprisingly diverse, including diet, hydration, pelvic floor dysfunction, medications, hormones, gut-brain interactions, and underlying medical conditions.

I’m hosting a FREE webinar on Friday, June 12 from 9am-9:40am.

In this free webinar, I’ll discuss:
✔️ What constipation actually is (and what’s normal)
✔️ Common causes across different ages
✔️ Symptoms you may not realize are connected
✔️ Evidence-informed strategies that can help

Join me for Constipation: From Babies to Adulthood and learn how to better understand one of the most common digestive complaints.

Period pain wrecking your gut? You’re not imagining it. Endometriosis and IBS often travel together—and your gut microbiome sits right in the middle.

What to know:
➡️ Endometriosis is a chronic inflammatory condition, not “just bad cramps.”

➡️ IBS is significantly more common in people with endo—many studies land around 20–40%, with about 3x higher odds overall.

➡️ The gut microbiome can influence inflammation, estrogen recycling (the estrobolome), gut barrier integrity, and pain signaling—so gut shifts can show up as pelvic pain, bloat, diarrhea/constipation, and nausea, especially around your period.

The take-away:
👉 Endo and IBS have a bidirectional relationship. Treating irritable bowel syndrome (IBS) can reduce endometriosis-related pain, and addressing endometriosis can ease IBS symptoms.

Save this for your next flare and share with a friend battling “endo belly.”

Ready for tailored support? Book a consult with me to map an endo–IBS plan that fits your symptoms and goals.

Bloating and distention are not the same thing.

Bloating = the feeling of pressure, fullness, or tightness in the abdomen. Like the sensation of having a balloon in the stomach.

Distention = a visible increase in abdominal girth.

You can feel bloated without looking distended, and sometimes you can have both.

And if all your tests are “normal” but you still feel bloated? There may be more to the story.

🎙️Comment “PODCAST” and I’ll send you Episode 5 of the Team Gut Girls Podcast, where we unpack why bloating can happen even when tests come back normal.

This is something we don’t talk about enough. Adverse childhood experiences (ACEs), which include childhood traumatic events like abuse, neglect, and household dysfunction, can set the stage for chronic digestive issues later in life.

In fact, about two-thirds of people with irritable bowel syndrome (IBS) have a history of ACEs. It’s thought that chronic stress in childhood primes the brain-gut-microbiota axis.

This is why healing your gut isn’t as simple as removing gluten, taking a probiotic, or following the latest diet trend.

Your digestive system isn’t just responding to what you ate—it’s responding to your history, your nervous system, and how your body learned to perceive and respond to stress.

For some people, the gut has been in a heightened, protective state for years. And unless that piece is acknowledged, it can feel like you’re doing everything “right” and still not getting better.

This is the work I do with my patients. We look beyond food and supplements and start to understand why your symptoms are happening in the first place—connecting the dots between your gut, your nervous system, and your lived experience.

Microbiome testing is one of the most popular tools in gut health right now. It’s also one of the most misunderstood.

A recent study showed that the same standardized stool sample sent to different labs produced very different results. This is because labs use different methodologies, databases, and interpretation models. There isn’t a standard when it comes to microbiome testing.

Your symptoms, your history, your patterns—those matter just as much (if not more) than what a test report says. If you’ve had gas, bloating, and issues with bowel movements for some time, you very likely have dysbiosis. We don’t need a fancy test report to tell us that.

If you’re trying to make sense of your gut symptoms (with or without testing), this is exactly what I help patients navigate.

Tired of navigating through the noise and conflicting health information online? Me too.

I'm excited to now be offering free monthly live webinars starting in March 2026 on a range of important health topics.

Each session will provide evidence-informed education to help you better understand what’s happening in your body and feel more connected between appointments — and more knowledgeable in these areas overall.

We’ll cover topics such as cholesterol, digestion, perimenopause, constipation across the ages, and metabolic health, to name a few. My goal is to offer clear, thoughtful discussion grounded in current research.

If you can’t attend live, no worries — we’ve got you covered. All registered participants will receive access to the recording.

Sustainable health rarely comes from trying harder. It comes from changing the systems that keep you stuck. If your systems aren’t working — your routines, habits, supports, or care plan — it’s not a failure. It’s information.

This is the work I do with patients: helping them step back, evaluate what’s actually happening, and adjust the systems so their health goals become achievable.
