Complete
the questionnaire
After choosing your appointment, you will receive a confirmation email and a link to a questionnaire to download and complete. Please also send us any recent test results before your consultation so that we have all of the information we need to build up a thorough understanding of your case.
Your
appointment
Although this isn't set in stone as it depends on your needs, generally on the day of your appointment we will take a detailed review of your health history and health concerns. We incorporate your medical history, family history, lifestyle, past and present diet choices plus genetic factors, to create a detailed timeline building a deep understanding of triggering and or significant events that have led to your health issues. We will then explain how any of these factors may be linked to your symptoms and discuss your unique plan.
After your
appointment
We follow up all appointments with a unique and personalised report with clear guidelines and recommendations. Your report could include handouts and advice about meal plans, lifestyle changes, supplements and test options. The depth of the plan depends on whether we have test results we are already working with and you are ready for an in depth plan or whether you are going to be making some preliminary changes whilst completing and waiting for test results.
Follow up
appointments
When we meet again we listen to feedback about the initial
changes you've made and offer further support and if you have
test results to review we will go over these in detail and
incorporate the findings into your plan.
The number of appointments you need is not fixed and really
depends on your starting place, test findings, how quickly you can
work on changes and how much there is to do.
