Currently, the only available treatment for a patient with celiac disease is a strict gluten-free diet. A lifelong diet completely free of gluten can be very costly and challenging. Many patients’ intestines don’t heal completely and they continue to suffer from symptoms, most often due to imperfect adherence to the gluten-free diet. Despite patients’ best efforts, accidental ingestion of gluten through cross-contamination continues to jeopardize their health and well-being. Future drug therapies are currently in development with the hope of reducing the burden of living with celiac disease and improving long-term health outcomes. Find out more below.
