A delay or difficulty in defecation sufficient to cause significant distress to the patient is defined as constipation.
Objectively it can be defined as duration of more than 4 weeks and presence of any 2 or more of the following:
(a) Defecation frequency ≤2 times per week
(b) Fecal incontinence ≥1 times per week after the acquisition of toileting skills
(c) History of excessive stool retention.
(d) History of large-diameter stools that may obstruct the toilet
(e) History of painful or hard bowel movements
(f) Presence of a large mass in the rectum or on per abdomen examination
One should keep in mind that it is the consistency of the stool not the frequency which is more important for defining constipation
