A dietitian is a regulated healthcare professional specialising in nutrition assessment and medical nutrition therapy.
Dietitians support a wide range of health conditions and nutrition goals using evidence-based approaches.
Dietitians provide personalised nutrition support based on your health needs, medical history, preferences and lifestyle. They can help with both prevention and management of health conditions, and may liaise with your GP or medical team.
You will usually discuss symptoms, medical history, medications, diet patterns, blood results (if relevant) and goals. A plan may include dietary changes, meal structure, symptom tracking and follow-up reviews.
Dietitians are regulated healthcare professionals. They are distinct from nutritionists (a broader term with varying regulation). If you have complex medical needs, a dietitian is often the most appropriate nutrition specialist.
Dietetics developed alongside clinical nutrition science in the 20th century. In the UK, dietitians practise within regulated healthcare standards, supporting medical nutrition therapy and evidence-based behaviour change.
