Functional constipation in a child (H3a) requires two or more of the following, each at least once per week, for a minimum of 1 month, with insufficient criteria for irritable bowel syndrome: two or fewer defecations in the toilet per week in a child of developmental age at least 4 years, at least one episode of fecal incontinence per week, retentive posturing or excessive volitional retention, painful or hard bowel movements, a large fecal mass in the rectum, and large-diameter stools that can obstruct the toilet. Retentive posturing, painful or hard stools, a rectal mass, and large-diameter stools do not count unless that feature is present at least once per week. After appropriate evaluation the symptoms cannot be fully explained by another medical condition. (2016)
