Dorset Allergy works closely with an adult and paediatric dietician to ensure you receive the full guidance you need to manage yours or your child’s allergy. Both of our dieticians have vast levels of experience of managing patients with allergies and gastrointestinal conditions, such as Irritable Bowel Syndrome or Inflammatory Bowel Disease.

If after seeing Doctor Helen, she believes you would benefit from dietetic input; with your permission she will make a referral to either Marianne (for adults) or Joan (for children) and a virtual consultation can then be arranged.
