Spastic colon is also called irritable bowel syndrome (IBS), a condition that affects your digestive system3. IBS is a common disorder that manifests with symptoms like abdominal pain, abdominal cramping, constipation, diarrhea, and bloating.

“Spastic colon” is a term that is often used to describe an increase in the spontaneous contraction or motility of muscles within the small and large intestines often associated with IBS. Such contractions may also be referred to as spasms.
