Researchers at Chelsea and Westminster Hospital are recruiting both identical and non-identical twins where at least one has Inflammatory Bowel Disease for a study of “Non-Genetic Factors in the Pathogenesis of IBD”.

Who can take part?

  • Identical twins and non identical twins
  • Either one or both twin diagnosed with Crohn’s Disease or Ulcerative Colitis
  • Over 18s
