The exact cause of IBS-C remains unknown. It is believed to be associated with alterations in intestinal motility and contractions, as well as changes in pain perception within the gastrointestinal tract. In certain cases, IBS-C may develop following a previous gut infection, and it could also be linked to disruptions in communication between the brain and intestines. Evidence suggests that the presence of specific gut bacteria or variations in their composition may contribute to the condition. Researchers are also investigating the potential roles of genetics and immune system changes in the development of IBS-C. While the precise mechanisms behind IBS-C are still being explored, multiple factors are believed to influence its occurrence.
