Zara Arrowsmith

Symptoms: Bloating and fatigue

Food Reactions: Yeast and Cow’s Milk

“I No Longer Feel Constantly Bloated or Tired – I Feel More Myself”

28-year-old Executive Assistant Zara Arrowsmith had been battling gut health issues for over a year. After a round of antibiotics, something changed; her digestion became unpredictable, and she found herself dealing with near-daily discomfort. No matter what she ate, it felt like her symptoms could flare up at any time.

Zara couldn’t identify her trigger foods, which left her feeling helpless. The flare-ups were intense and unpredictable, and she began to feel constantly bloated, sluggish, and uncomfortable after eating. Her symptoms started affecting her ability to focus and feel like herself at work, and they were interfering with her quality of life.

Desperate for answers, Zara came across YorkTest online. She ordered her test in July 2025, hoping for clarity. The results revealed intolerances to cow’s milk and yeast: two common ingredients that had likely been fuelling her symptoms all along.

With this knowledge, she began cutting out her trigger foods. While yeast in particular proved difficult to avoid due to how widely it appears in processed foods, Zara committed to the plan. With support from YorkTest’s nutritional consultation and Customer Care Team, she found realistic alternatives and stuck with the dietary changes.

Within just a couple of weeks, Zara saw real improvement. The bloating eased. Her energy returned. She finally started to feel more in control, and more like herself.

She’s now able to maintain a regular routine, with no more guessing games around food. And when she does occasionally eat something she’s intolerant to, the bloating and fatigue return, confirming just how powerful these changes have been.

If you’re experiencing digestive issues like Zara was, and suspect food could be a trigger, YorkTest can help. Take control of your gut health with one of our at-home food intolerance tests and start feeling more like you.
