Constipation is "Infrequent or difficult evacuation of feces. These symptoms are associated with a variety of causes, including low dietary fiber intake, emotional or nervous disturbances, systemic and structural disorders, drug-induced aggravation, and infections."[1]
Classification
Constipation may be classified by colonic transit time testing. The oralanal transit time the amount of time required for radiopaque markers to transit from the mouth to colon. Normal is less expelling more than 80% of markers within 67 hours[2] to 72[3] hours.
Slow-transit constipation
Slow-transit constipation is associated with hard stools.[4] In a case series of women whose oralanal transit times were over 5 days, subjects averaged one bowel movement per week.[5]
Slow-transit constipation may be associated with delayed gastric emptying in 60%[6] to 75%[7] of patients.
Slow-transit constipation may be associated with other signs of autonomic dysfunction[7]
Treatment
Dietary fiber is the principle treatment.[3]
Patients with slow-transit constipation may be less likely to respond to dietary fiber.[2]
