About me

I am a multi-award winning IBS Dietitian based in Cardiff with over 20 years' experience. I offer expert advice using the low FODMAP diet approach. I have a wide range of experience, but my main area of expertise is the treatment of irritable bowel syndrome (IBS) and other digestive issues. I can advise and support you using the low FODMAP diet approach. Usually just 2 sessions are necessary for most people. 

As founder of FODMAP Consultancy, I offer one-to-one sessions across South Wales and Skype consultations.

Wheelchair user access

Wheelchair-accessible premises should have step-free access for wheelchair users and individuals who are unable to climb stairs. If a nutritionist's premises aren't step-free, they may offer alternative services such as telephone/web-based appointments, home visits, or meeting clients in different location, so you can choose the option that suits you best.

You can contact the nutritionist to discuss the options available.

Under the Equality Act 2010 service providers have a duty to make reasonable adjustments to ensure that individuals with disabilities can access their service. You can read more about reasonable adjustments to help you to access services on the CAB website.
