About A -Z Health

The Name is built on what Claire Harris (MSc) witnessed and wished to established 19 years ago when she moved to Southsea for a family and working life, this was 7 years after initally discovering the revolutionary health and healing Colon Hydrotherapy provided and then being part of prestigious Health centres, such as The Hale Clinic, Regents Park, Balance on the Kings Road. Alongside this Claire attended Regents College to develop her work in natural nutritional education. 

Claire went on to support (ARCH) The Association for Registered Colon Hydrotherapist, as Chair after the passing of its Founder Roger Groos in 2024. Claire works in a bespoke way with each and every person - as listening to individuals health history and issues, combined with longstanding clinical practice and the knowledge this brings is critical to good and sound care.

Clients who chose this path of healing and healthcare prevention are greatly admired by Claire as she know what it takes to explore this and trust in your own body's intelligence.

Claire's Story - in more detail:   

Claire is one of the UK’s most experienced Colonic Hydrotherapists, with over 26 years of clinical practice and Chair of the Association of Registered Colon Hydrotherapists (ARCH). Her work combines Colon Hydrotherapy with advanced nutritional therapy to support long-term gut health and wellbeing.

Claire cleared Atopic Eczema, IBS symptoms and PCOS at 23 years old after falling ill just months after gaining a first class honors degree in Fine Art,  Claire began out of necessity, researching natural health and healing approaches after Medical consultants sentenced her to a lifetime of atopic eczema, stating diet changes will not do anything and it proably will be for life.  Claire applied her then newly found research and fresh insights on health to her own health break down and somehow knew she was on the right path. Claire has spent her life teaching people how to gain clearer health and apply the right nutrition and cleansing for whole body health, with 26 years in professional practice here in the UK and USA.

A-Z Health was set up in 2007 by Claire, with a desire to work in a truly personal way with individuals, especially in helping them navigate the confusion around limited advice for IBS to the minefield of Nutritional Health advice. Naturopathically trained, all therapies and services provided are fully certified and insured. All light and heat treatments, including Infrared, aromatherapy essential oil, and botanical skincare products are all clinical certified.

A-Z Health was established, and is run to provide individuals with professional help, guidance and treatments no matter what their condition or situation. Over the past 26 years Claire has been dedicated to bringing Complementary Healthcare into people's lives. Claire has been qualified and in Practice as a Colon Hydrotherapist since 2000 and Nutritionist since 2001, and completed an MSc in Nutrition and Behaviour, with research on IBS symptoms.

I recently had a session with Claire, and I couldn’t be happier with the experience. The atmosphere was calming and welcoming from the moment I arrived, which really helped put me at ease. I was quite nervous at first, but Claire was so lovely, caring, and professional that I felt comfortable almost straight away. She guided me gently through the whole process, explaining everything clearly and making sure I was relaxed at every step. Her warm, reassuring manner made the session much easier than I expected. I'm truly grateful for her kindness and expertise. I highly recommend it!

This was my first experience having colonic hydrotherapy and also l was nervous and unsure of the procedure but Claire soon put me at ease with her lovely warm welcome. Before having the procedure time was spent discussing my health and expectations and during Claire explained step by step and always checked l was comfortable at all times. I will be having a follow up appointment and would definitely recommend it to friends. Thank you for a stress free experience. 😍
