🍋What is IBS?

IBS is a functional bowel disorder affecting approximately 1 in 20 people in the UK. Typically symptoms include abdominal pain, cramps, bloating and altered bowel habits such as diarrhoea, constipation or a mix of both. IBS is debilitating, affecting day-to-day life, mental well-being and overall health.

🍋Low FODMAP Diet for IBS relief

The low FODMAP diet is recommended by the NHS as an effective IBS treatment. It provides IBS relief to over 75% of sufferers in just a few weeks.

It involves restricting foods known to be high in FODMAPs. When symptoms improve, the reintroduction phase helps to identify triggers. For most people, these are few in number. Once you know which foods trigger your symptoms, you can avoid or limit them and get back to a more normal diet.

🍋IBS relief with an IBS Dietitian

IBS can be unpredictable and exhausting — but with the right support, it is manageable. The low FODMAP diet is a tricky diet to follow alone, but that’s where I come in. As a Specialist IBS Dietitian, I bring:

• A deep understanding of the science behind IBS

• Accreditation by King’s College, London to deliver low FODMAP protocol

• A supportive, step-by-step approach tailored to your unique symptoms

Unlike generic advice online, you’ll receive professional, personal guidance that targets your specific triggers — so you can eat with confidence again.

🍋My Training and Background

I trained in FODMAPs at King’s College London and have been a Registered Dietitian (BSc RD) since 2000. My NHS career includes roles in:

• Gastroenterology

• Nutrition Support

• Specialist IBS Services

Now in private practice, I combine clinical insight with a warm, practical approach that fits into real life.

My Ethos

Since 2015, I’ve advised over 2000 people with IBS symptoms.

Many of my clients have been living with pain and discomfort for most of their lives. Some are housebound because their symptoms make even short journeys impossible. And most are afraid to eat because they just can’t work out what’s triggering their IBS.

My experience has helped me to understand the stress and disruption that living with IBS symptoms cause. As an IBS dietitian and FODMAP expert in IBS treatment, I’m driven to share my knowledge and expertise to help IBS sufferers across the UK.

The low FODMAP diet, under the supervision of a qualified IBS dietitian, is a relatively straightforward process to follow, and yet the results are undeniably life-changing. This diet is research based and recommended by the NHS as an effective treatment.

I’m truly humbled and feel privileged to be able to share my expertise and knowledge and to help my clients get back to living a full, IBS symptom-free life.
