Overview
Irritable bowel syndrome (IBS) may be classified according to Rome IV criteria into four subtypes/groups: IBS with predominant constipation , IBS with predominant diarrhea, IBS with mixed bowel habits,and IBS unclassified. In addition, IBS occuring subsequent to GI infections is known as PI-IBS or post infectious IBS.[1]
Classification
Irritable bowel syndrome (IBS) may be classified according to Rome IV criteria into 4 subtypes:
- IBS with predominant constipation
- IBS with predominant diarrhea
- IBS with mixed bowel habits: alternating patterns of stool passage which is not in conjuncture with the normal bowel movements.
- IBS unclassified: Patients who meet the diagnostic criteria for IBS but whose bowel habits do not fit into any of the above subtypes.
- IBS-PI or post infectious IBS. It is an additional subtype described that occurs subsequent to infections of the GI tract.
SUBTYPE | HARD OR LUMPY STOOLS | LOOSE(MUSHY) OR WATERY STOOLS |
---|---|---|
IBS with constipation | ≥ 25 percent | ≤ 25 percent |
IBS with diarrhea | ≤ 25 percent | ≥ 25 percent |
Mixed IBS | ≥ 25 percent | ≥ 25 percent |
Unsubtyped IBS | Insufficient abnormality of stool consistency to meet criteria for IBS with constipation, diarrhea, or mixed subtypes. |
