Overview
When the stool is hard, infrequent, and requires significant effort to pass, you have constipation. The passage of large, wide stools may tear the mucosal membrane of the anus, especially in children. This can cause bleeding and the possibility of an anal fissure.
Diagnostic Criteria
The diagnostic criteria based on the American Gastroenterological Association (AGA),[1] Rome III criteria[2] and pharmacologic studies based criteria[3] is as follows.
| Rome III criteria[1][2] | Pharmacologic studies based criteria[1][3] |
|---|---|
| Symptom onset for ≥6 months and ≥2 of the following for the past 3 months:
● Straining during at least one-fourth of defecation |
Spontaneous bowel movements <3 per week and ≥1 of the following for at least 12 weeks during the past 12 months:
● Straining during more than one-fourth of defecation |
