If you’ve ever felt a wave of anxiety before a big meeting, only to be hit with stomach cramps or urgent bathroom trips, you’re not imagining the connection. Irritable Bowel Syndrome (IBS) and anxiety are deeply intertwined, especially for Canadian women, who are diagnosed with IBS at twice the rate of men. New research from the University of Toronto suggests that gut imbalances may actually trigger anxiety, not just the other way around (Hopkins Medicine, 2023).
Why Your Gut Is Your "Second Brain"
Your gut produces 90% of your body’s serotonin, the "feel-good" hormone (Harvard Health, 2022). When gut bacteria are out of balance (thanks to stress, diet, or antibiotics), it can disrupt mood and digestion. Dr. Emily Wong, a gastroenterologist at Women’s College Hospital in Toronto, explains: "Many of my IBS patients describe a vicious cycle, stress flares their gut symptoms, which then worsens their anxiety."
The Canadian Factor
Stress Triggers: A 2024 StatsCan survey found that 43% of Canadian women report high stress levels, compared to 31% of men.
Diet Matters: Processed foods and lack of fibre feed harmful gut bacteria. The low-FODMAP diet (developed at Monash University) can help.
3 Science-Backed Ways to Break the Cycle
Try a Low-FODMAP Diet (Temporarily)
Reduces fermentable carbs linked to bloating and pain. Work with a dietitian to avoid nutrient gaps (CDHF, 2024).
Prioritize Sleep & Movement
A McGill study found that 30 minutes of daily walking reduced IBS flare-ups by 50%. Yoga also calms the gut-brain axis (Frontiers in Psychology, 2025).
Ask About Probiotics
Bifidobacterium infantis 35624 significantly reduces bloating, per a UBC trial.
"After years of embarrassing symptoms, I finally got relief by addressing my gut health," says Toronto teacher Maria Lopez.
The Bottom Line: If anxiety and IBS are ruling your life, talk to your doctor, Mayo Clinic’s IBS guide offers more treatment options.
