Introduction

Constipation is a common complaint, especially in women and older adults. It results in millions of physician visits per year, with hundreds of millions of dollars spent on laxatives. Untreated it can lead to serious morbidity and can be a contributing factor in mortality. A rational approach to the patient presenting with constipation includes a detailed history, general and focused physical examination, specific investigations, and appropriate therapy.
