Dermot Anderson Profile

Dermot Anderson

Symptoms: Pain behind the eyes, Headaches, Fatigue

Food Reactions: Yeast and Cashew Nuts

“I would go as far as to say the testing has been life-changing — it’s the best money I’ve ever spent.”

55-year-old Dermot Anderson, an accountant, had been experiencing persistent symptoms for around two years, including pain behind the eyes, headaches, and ongoing tiredness.

While these symptoms didn’t stop him from carrying out his daily routine, they gradually became draining. Dermot found himself needing to go to bed earlier than usual, and the combination of dull pain and fatigue began to take a toll on his overall energy levels.

Despite trying alternative routes, including an airborne allergy test and lower-cost testing methods, he struggled to get clear answers. The results he received previously were incomplete and didn’t provide the clarity he needed.

After reading about YorkTest on the Boots website, Dermot decided to take action. He was looking for a quick and reliable answer, and the speed of the process stood out. From ordering the test to receiving his results, the entire journey took just a few days — something that made a strong first impression.

The results revealed intolerances to yeast and cashew nuts, confirming Dermot’s suspicion that certain foods – particularly bread and nuts – were likely contributing to his symptoms. The test didn’t just highlight that something was wrong; it pinpointed exactly what he needed to avoid.

After removing these trigger foods from his diet, the improvement was almost immediate. Within just a couple of days, Dermot began to feel like himself again. The dull pain disappeared, his energy levels increased, and he realised how much better “normal” actually felt.

He also noticed that when symptoms did return, they could be directly traced back to specific foods. By checking ingredients, he was able to confirm that each reaction aligned with something flagged in his results — reinforcing his confidence in the accuracy of the test.

The elimination process itself was simple, and Dermot has continued to follow his diet plan. With only a small number of trigger foods to avoid, making adjustments was straightforward and easy to maintain.

If he consumes those trigger foods, the symptoms quickly return, particularly headaches and tiredness, acting as a clear reminder of the impact those ingredients have on his body.

Today, Dermot feels more energetic, pain-free, and reassured. Perhaps most importantly, he now understands the cause of his symptoms and feels confident in how to manage them moving forward.
