Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS that leads to abdominal pain, gas, bloating, and frequent, urgent diarrhea. The exact causes are unknown, but research suggests that multiple factors — such as the gut-brain axis, abnormal muscular contractions, gut microbes, and genetics — could play a role in the disease. IBS-D can be managed with dietary modifications, psychotherapy, supplements, and prescription medications.
Diarrhea Predominant Irritable Bowel Syndrome (IBS-D) falls under the Gut Health category.
