Functional Testing: A Deeper Insight

As a London-based gut health specialist, I support clients with IBS, SIBO, bloating, reflux, IBD and complex functional gut disorders.

When symptoms feel confusing or persistent, functional gut testing can offer powerful clarity. Using trusted laboratories such as GI360 and SIBO breath testing, we can assess microbial balance, inflammation, digestion, absorption, and bacterial overgrowth - giving us a detailed picture of what’s really happening inside your gut.

Testing is never about overwhelming you with data. It’s about uncovering the root cause so we can create a precise, personalised plan that supports long-term healing, not just symptom management. Together, we’ll decide whether testing is appropriate for you during your consultation, based on your symptoms, history, and goals.
