IBS is mainly observed in the adult population and is more common in women. The different manifestations of this syndrome are the following:
Abdominal pain: It appears in the form of stomach cramps of varying intensity. Emotional stress is sometimes a trigger. Most of the time, having a bowel movement relieves the pain.
Changes in bowel habits: IBS can cause diarrhea, constipation or a combination of these two conditions.
Diarrhea: In this case, bowel movements usually occur in the morning or after meals. They are often followed by a feeling of incomplete evacuation. A mucous discharge may be observed after the bowel movement.
Constipation: It can be intermittent and last several days. The stools are often hard and pellet-shaped. In addition, the impression that the bowel is not completely emptied can lead to unnecessary straining.
Other common symptoms include bloating, gas, flatulence and belching.[3]
