A nutritionist aims to help you improve your diet to achieve your optimum health through an evidence based approach of diet and lifestyle changes. They will look at you as a whole and aim to get to the root of your problems rather than just treat your symptoms. People seek or are recommended nutritional help for a number of reasons and everyones needs are different which is why one diet does not suit all.
They will take you through a consultation which will ask questions about your lifestyle, diet, any medical conditions, medical history or family medical history. They can offer food intolerance and allergy tests which will help to devise the programme they recommend for you. They often will prescribe safe does of natural supplements such as probiotics or vitamins to help symptoms or optimise digestion. The number of times you need to see them depends on the person but they should be able to give you an outlook on a programme and how long it will need to go on for after the first consultation.
