==Overview==
==Overview==
[[Constipation]] in adults may be due to side effects of medications such as [[antispasmodics]], [[anticholinergics]], [[analgesics]] or may be associated with systemic disorders like [[diabetes mellitus]] and [[hypothyroidism]].  Idiopathic constipation should be considered once the secondary causes are ruled out and it may be associated with normal or slow colonic transit, dysfunction in defecation, or both. Constipation in childhood often resolves with age after proper guidance regarding diet, toilet training, and toileting behaviors.

Overview

Constipation in adults may be due to side effects of medications, such as antispasmodics, anticholinergics, analgesics; or may be associated with systemic disorders, such as diabetes mellitus and hypothyroidism. Idiopathic constipation should be considered once the secondary causes are ruled out and it may be associated with normal or slow colonic transit, dysfunction in defecation, or both. Constipation in childhood often resolves with age after proper guidance regarding diet, toilet training, and toileting behaviors.
