    What to do for Irritable Bowel Syndrome in Children ?
    ### Response:
    - Irritable bowel syndrome (IBS) is a functional gastrointestinal (GI) disorder, meaning it is a problem caused by changes in how the GI tract works. Children with a functional GI disorder have frequent symptoms, but the GI tract does not become damaged.  - IBS is not a disease; it is a group of symptoms that occur together.
