Constipation is a common form of irritable bowel syndrome. Depending on the symptoms of the disease, the patient needs to be treated with drugs and a diet that is suitable for the disease.

Constipation-type irritable bowel syndrome is a type of irritable bowel, other types include IBS with diarrhea (IBS-D). Although all types of IBS can cause changes in bowel movements along with abdominal pain, there are more obvious symptoms if you have constipation-type irritable bowel syndrome.

People with irritable bowel syndrome with constipation often have lower serotonin levels, the muscles in their rectum are less responsive to serotonin, and they are more likely to pass hard or lumpy stools. People with irritable bowel syndrome and high serotonin levels may experience diarrhea and their rectum more reactive, passing loose or watery stools.
