Do you have IBS with diarrhoea? The Relieve IBS-D clinical research trial is testing the efficacy of Enterosgel to treat diarrhoea and abdominal pain in people with IBS-D. Enterosgel is an intestinal adsorbent in the form of a gel, which can be mixed into water. It's drug-free, and currently available in retail stores and pharmacies. If you would like to take part in the study, please visit the Enterosgel website. There are enrolment sites across England, including London.
