World Trade Center Health Program; Petition 019-Irritable Bowel Syndrome; Finding of Insufficient Evidence

On May 17, 2018, the Administrator of the World Trade Center (WTC) Health Program received a petition (Petition 019) to add irritable bowel syndrome (IBS) to the List of WTC-Related Health Conditions (List). Upon reviewing the scientific and medical literature, including information provided by the petitioner, the Administrator has determined that the available evidence does not have the potential to provide a basis for a decision on whether to add IBS to the List. The Administrator also finds that insufficient evidence exists to request a recommendation of the WTC Health Program Scientific/Technical Advisory Committee (STAC), to publish a proposed rule, or to publish a determination not to publish a proposed rule.
