What causes IBS with constipation?
Contrary to what many people think, IBS is not caused only by stress or eating habits. Until recently, the cause of IBS has been poorly understood and underappreciated. However, in recent years, new research has yielded a better understanding of the cause of IBS. People who suffer from the abdominal discomfort or pain, bloating, and constipation of IBS may have a digestive system that is more sensitive or works more slowly than it should, possibly because of the way their digestive system reacts to changes in a naturally occurring chemical in their body called serotonin. Serotonin regulates movement in the digestive system and the perception of abdominal discomfort and pain.
