Irritable bowel syndrome (IBS) is the most common gastrointestinal (GI) disorder worldwide. Despite its prevalence, IBS remains underdiagnosed in the United States—fewer than half of adults with the condition even receive a formal diagnosis.
The condition manifests differently in each person, with symptoms ranging from mild inconvenience to significantly affected daily life. However, IBS does not cause permanent damage to your intestines or lead to serious diseases like cancer.
