They use the most up-to-date public health and scientific research on food, health and disease which they translate into practical guidance to enable people to make appropriate lifestyle and food choices. Dietitians are the only nutrition professionals to be regulated by law.

They are governed by the ethical code of the Health and Care Professions Council, to ensure that they always work to the highest standard.

Leah Seamark – Registered Dietitian (BSc, PgD, HCPC Registered)

I qualified as a Registered Dietitian in 2009, following completion of a Postgraduate Diploma in Dietetics at the University of Wales Institute Cardiff. This was following my initial BSc (Hons) degree in Sports and Exercise Sciences from the University of Birmingham. My first job was as a dietitian on the wards at Queen Alexandra Hospital, Portsmouth, where I gained valuable experience in managing a wide range on conditions in the acute stages. I then spent 2 years working as a community dietitian in Portsmouth, before moving to Dorset in 2013.

Since 2013, I have been working as a community gastroenterology dietitian for Somerset NHS Foundation Trust. This job has involved managing a general dietetic caseload of patients referred via GPs for a wide range of conditions, as well as a specialist role in managing conditions associated with the gut. This includes irritable bowel syndrome, diverticular disease, constipation, food intolerances, coeliac disease, inflammatory bowel disease and gut health. I also have an interest in dietary factors associated with the menopause. I am actively involved in research and service evaluations and have contributed to various published papers. I continue to be the clinical lead for the community gastroenterology dietetic service alongside my private practice.

I am passionate about supporting people to explore the dietary treatment options for their condition and symptoms. However, I am very much aware that for many people, especially those experiencing gut symptoms, diet is only one management option. Many people experience benefits in some of the complimentary treatments available that focus on addressing the communication process between the gut and the brain, which following a detailed assessment, we can discuss.

I live in Dorset with my husband and 2 young children, and in my free time you will find me enjoying the beauty of the surrounding area, either on foot, on a bike or on a paddleboard.
