About Clemmie

I was diagnosed with ulcerative colitis in 1999 aged 9, had surgery to remove my colon in 2001 aged 11, lived with an ileostomy bag through my teenage years and had ileal pouch anal anastomosis (IPAA) construction and ileostomy reversal in 2009, aged 18. I continued to experience digestive problems for years despite being given the all clear. I became ill again after moving to London and working in a stressful PR job.

I felt bloated all the time and nauseous whenever I ate, I lost weight, started losing my hair and generally felt terrible and totally helpless. I didn’t know what else to do, so I went to see a nutritional therapist and it completely changed my life forever. I discovered that I could transform my digestion and health through diet and lifestyle medicine. That experience was so powerful that I quit my job and trained as a nutritional therapist. I never want anyone to feel the way I felt again which is why I am now helping so many people who have IBD to help manage their conditions. There is so much we can do to help support IBD through the food we eat and the way we live and it is my mission to help as many people as I possibly can realise and benefit from this. 

I founded the Nutrition and Lifestyle Medicine (NALM) Clinic in 2018 specialising in supporting people with IBD. I see clients via video call and in person in London. I am absolutely passionate about helping and empowering people with IBD to support their conditions through what they eat and the way they live so they can live life to the full again.

My approach is completely personalised to each individual client I work with depending on their condition, current health, food likes, dislikes, tolerances or intolerances, life and other commitments. I work together with my clients to focus on positive food and lifestyle choices that help support their condition and fit in with their lives to help support the long term management of their Crohn’s disease and ulcerative colitis.
