Chronic Idiopathic constipation
Constipation affects up to 28% of Americans in 4 pathophysiologic patterns: slow transit constipation, dyssynergic defecation, a combination of both, and normal colon transit with normal pelvic floor function. Constipation may be a part of a generalized gastrointestinal (GI) tract transit disorder. The purposes of this study were to determine the percentage of constipated patients with the different pathophysiologic subtypes and and to evaluate what percentage of constipated patients has a diffuse GI tract transit disorder.
