Step-by-step explanation:
Irritable bowel syndrome (IBS) is a chronic gastrointestinal disorder characterized by abdominal pain and changes in bowel habits. It is often associated with stress and can be triggered by certain foods or medications. The patient's experience of abdominal pain being relieved by bowel movements is a common characteristic of IBS. It is believed that serotonin, a neurotransmitter, plays a role in the regulation of gastrointestinal function and mood, and abnormalities in serotonin signaling may contribute to the development of IBS. Soluble fiber supplements may be beneficial in managing the symptoms of IBS.
