Fettle & Bloom was launched by Bath-based NHS dietitian Cristy Dean BSc MSc to provide tailored, expert and dedicated support to those with irritable bowel syndrome (IBS) and related gut health conditions. After graduating from the University of Plymouth with a first-class degree in nutrition and dietetics, Cristy spent many years working in a range of NHS gastroenterology ward settings, specialist IBS clinics, university research centres and in the digital health arena as a specialist diabetes dietitian.

Having seen the devastating effects of IBS on patients and the lack of specific support they were receiving, Cristy has since dedicated her career to supporting patients with complex gastro-related illnesses, empowering people through proven, evidence-based strategies that can greatly improve their diets, health, lifestyle and general wellbeing.

As well as running her own clinic, Cristy writes on gastroenterological (gut health) topics, provides nutritional support in the management of complex oncology and intensive care patients in her hospital role, educates children and adults on nutrition, and has assisted with pioneering clinical research into the role of dietitians helping to support people with the management of type 2 diabetes. In keeping with the growing trend in plant based eating, Cristy has fully educated herself to provide specialist assistance for those who want to transition and thus, ensued a role as a plant-based dietitian.

Cristy is registered with the Health and Care Professions Council and the British Dietetic Association, and is a member of the Freelance Dietitians Group, gastroenterology and oncology specialist dietitian groups.

Between 7 – 20% of the population worldwide suffer from Irritable bowel syndrome and yet a much larger percentage go undiagnosed

Our Journey 3

It’s a common misconception that there’s nothing you can do to effectively treat irritable bowel syndrome (IBS) – that it’s up to you, on your own, to figure out a way to manage the condition as best you can.

Having extensive experience and specialist expertise of working with hundreds of IBS sufferers, we know it doesn’t have to be that way. Approximately 75% of people who go on to a low fodmap diet will experience controlled symptoms of IBS, which in turn improves their stress levels and quality of life. Increasingly, we have a better understanding of the link between the gut and our brain. Our ‘gut brain axis’ has a bidirectional flow of information that occurs between the brain and the gut. It can trigger the emotional shifts experienced by people coping with IBS, abdominal pain and diarrhoea. This helps us to understand why, in the IBS population; psychological disorders such as anxiety and depression are more common.

If this sounds familiar, you are not alone. At Fettle & Bloom, our Bath-based IBS dietitians are here to support you. We understand that every individual’s experience is different, which is why we provide a personal approach that will ensure you feel listened to, cared for and supported as we work together to find a solution.

This involves spending time one on one, using evidence-based approaches to get to the underlying causes of your symptoms, and building tailored plans with supporting resources such as apps, recipes and meal plans.

It’s all about giving you the confidence to understand and manage your IBS condition better, so you can get back to living life to the full.
