✈️ Does the thought of travelling upset your gut before you've even left home?

Travel can disrupt your gut in more ways than you might think.

If you live with IBS, IBD, or celiac disease you aren’t alone in your worries about travelling. Worry about access to washrooms during long road trips, stress about eating meals out, and the impact of flying on the gut are all common concerns.

But, with the right plan it doesn’t have to be that way. ❤️

Understanding why travel affects your gut is the first step toward preventing flare-ups and feeling more confident wherever your trip takes you!

In my guest article for Gastrointestinal Society Inside Tract® newsletter, we break down:

✈️ Why flying can trigger bloating & constipation

🧠 How stress and disrupted routines affect digestion

💧 Nutrition, hydration, and movement tips to help prevent flare-ups

🎒 What to pack in a gut-friendly travel kit

🌎 Simple strategies to travel with more confidence

Because your gut shouldn't dictate your travel plans!

Want to understand why travel can influence your digestive function and how you can navigate without the gutdistress?

& be sure to subscribe to the GI Society's inside tract newsletter for their quartley issue! (I love taking mine to read at the coffee shop ☕️ when they come in 😌)

If you live with a gastrointestinal (GI) condition such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) or celiac disease, you likely understand the complexities of navigating your condition while travelling.

Celiac disease is a chameleon condition.. Could you be missing the red flag symptoms? 👀

🌾  While gluten-related disorders exist on a spectrum, celiac disease is a serious autoimmune condition that requires a strict, lifelong gluten-free diet.

Even ingesting small amounts of gluten, like crumbs from a cutting board or toaster, can trigger small intestine damage for people with Celiac Disease. ⚠️

The consequences of untreated celiac disease extend far beyond digestive symptoms…. 

It can increase the risk of other autoimmune conditions, including type 1 diabetes and multiple sclerosis (MS), as well as anemia, osteoporosis, infertility, migraines, heart disease and intestinal cancers.

🎙️ That’s why I was so excited to sit down with Selena Devries, Registered Dietitian and the founder of Celiac Made Simple. 💛

In this episode of the GutFit Nutrition podcast + youtube, we discuss:
✨ What celiac disease is, and the difference between gluten sensitivity and fructan intolerance
🥣 A typical day in the life of someone with celiac disease
🔗 Link between celiac disease and IBS
🛠️ Top tools for navigating celiac disease in 2026

🌾 Gluten isn't the problem for everyone…but celiac disease is something we need to take seriously.

If you've been navigating digestive symptoms for a while, you've probably considered going gluten-free or perhaps completed a low FODMAP diet.

One important distinction? Gluten is a protein found in wheat, spelt, rye and barley,,, it is not a FODMAP.

🩺 While gluten-related disorders exist on a spectrum, celiac disease is a serious autoimmune condition that requires a strict, lifelong gluten-free diet.

Even ingesting small amounts of gluten, like crumbs from a cutting board or toaster, can trigger small intestine damage for people with Celiac Disease. ⚠️

The consequences of untreated celiac disease extend far beyond digestive symptoms….

As someone living with celiac disease herself, she knows first hand what it’s like to live with celiac disease and helps her clients thrive on a gluten free lifestyle.

My client Cindy hit a marathon PB with zero gut issues 👏🏻👏🏻

Cindy Gallant is a Toronto-based realtor and endurance runner known as “The Running Realtor,” balancing a busy real estate career with a genuine love for running and an active lifestyle.

Before working together, she had a tough race and dealt with several bathroom stops that derailed her chances of hitting a PB, after working so hard in training.

She knew that something had to change, and she didn’t want to race the Boston Marathon again with the same outcome..From her words she said “If I need expert help, I’ll hire an expert. I wouldn’t try to fix a plumbing job myself, I’d hire a plumber.”

She decided to work with a Registered Dietitian experience in GI issues and endurance nutrition, and signed up to work together in my program! 👏

Cindy didn’t piece together random advice online, and use generic fuelling guides.

In working together:
👉🏻 We set up foundational habits to improve gut resilience and overall digestive health (to improve her guts ability to handle intense efforts)
👉🏻 Developed personalized fuelling plans for different runs and workouts (long runs, easy runs, speed) with options that were GI friendly to help reduce risk of gut issues
👉🏻 She received high touch support, accountability, and personalized guidance through our 1-1 sessions & private health portal
👉🏻 We focused on rebuilding confidence around fuelling, rather than creating fear and restriction
👉🏻 We created a tailored carb loading and race day plan that she practiced in training and executed for her big race day

The result?

A marathon PB with zero digestive issues!😍

This is exactly what I help clients with as a Dietitian specializing in digestive health & performance nutrition…

If you're ready to feel calm, confident, and in control of your gut symptoms and endurance fuelling, I’d love to work with you.

Unlike many programs, I combine evidence-based nutrition & lifestyle strategies with personalized protocols, 1-1 sessions, weekly journal reviews, and ongoing support to help you stay on track and crush your goals. Head to gutfitnutrition.com/apply for coaching.

A few weeks ago, I raced my second HYROX competition (shout out to my partner & personal trainer Mike Burroughs!) and finished in the top 13%, without a single GI symptom.

That wasn't luck…

It was the result of a nutrition strategy built around:
✔️ A small carb load tailored to the demands of the event
✔️ Lower FODMAP + fibre food choices to reduce GI risk
✔️ Planned hydration and sodium intake
✔️ Strategic caffeine timing for an evening race
✔️ Practicing every aspect of the fueling plan before race day

In this episode, I’m taking you behind the scenes of my full Ottawa Hyrox race weekend, 2 days out all the way through race day and recovering after as a gut health Dietitian and endurance athlete.

The thing with endurance athletes including both long distance runners and hyrox athletes is that they often mismanage their carb load, or try something new on race day… and that’s where things can go sideways fast, especially for those of us with sensitive guts.

While AI can be a helpful tool, it lacks the clinical experience to make nutrition therapy recommendations, regulation and accountability and ability to assess safety of a recommendation.

This trend makes sense, lack of support from the public medical system, you want to feel seen and heard, so you will turn to ways of obtaining advice and support that you feel gives you more answers and empathy. Which I absolutely understand.

However – we do need to be cautious of using AI for our own health guidance and information, because there are a lot of ways it can go wrong.

In this week’s episode, we discuss:
✅ The main downsides to using AI for gut health & IBS advice (lack of regularity, lack of context, data collection & hallucinations)
✅ Why data collection with these large language models (LLM) is something you need to be aware of
✅ How lack of context can result in misleading or dangerous health information
✅ How to navigate information online & use these tools more judiciously should you choose to

The Gut Harmony Method program is changing lives for those with IBS and chronic GI issues, and this is exactly why I’ve been doing this work for almost a decade.. ❤️

Yes of course it’s great that you’re no longer dealing with daily bloat, pain, or digestive upset, but you’re also able to…

✅ eat at restaurants without worrying about a painful flare-up afterwards

✅ travel without spending the entire trip thinking about your gut

✅ feel comfortable expanding your diet and enjoying more foods again

✅ have the energy to exercise, socialize, and fully participate in life

Because when you’re days are ruled by IBS and chronic gut symptoms… it’s rarely just about the symptoms themselves.

It’s about the impact they’re having on your confidence, relationships, social life, travel, exercise, and overall quality of life.

That’s why clients join the Gut Harmony Method**®**  👏🏻

Rather than simply removing more foods or chasing quick fixes, we focus on identifying what’s actually driving your symptoms, supporting your gut microbiome, improving food tolerance, and helping you build sustainable habits that fit your real life (through 1-1 high touch personalized support!).

So they can finally spend less time thinking about their gut and more time actually enjoying their life 😍

If you’re ready to stop letting IBS dictate your decisions and finally feel more in control of your symptoms, there are a limited number of spots available inside Gut Harmony Method**®** this summer!
