what is ibs
IBS is best understood as a long-term or recurrent disorder of gastrointestinal (GI) functioning. It usually involves the large intestine (colon) and small intestine with disturbances of intestinal/bowel (gut) motor function (motility) and sensation. These gut related activities are regulated by the brain. This may also be impaired, which is why IBS is often called a brain-gut disorder. These disturbances can produce symptoms of abdominal pain or discomfort, bloating or a sense of gaseousness, and a change in bowel habits (diarrhea and/or constipation).
