abstract
Constipation is a symptom that affects around 11-20% of the adult population yearly. Most physicians consider infrequency of defecation as a hallmark of constipation. However, most patients view excessive straining as the biggest component of constipation and only a minority of patients with constipation have infrequent bowel movements. Constipation might be due to many different medical conditions or occur as a side-effect of drug therapy. When these medical conditions or drug therapies are not present, a diagnosis of functional constipation, chronic idiopathic constipation, or irritable bowel syndrome with constipation is often made. In all patients with constipation, rectal outlet dysfunction should be excluded by physical examination because this condition occurs in approximately 25% of patients diagnosed with idiopathic constipation and can be improved with different therapeutic approaches than administration of laxatives. Because of the availability of over-the-counter laxatives, most patients consider themselves able to self-manage constipation, and patients have often tried many different treatments before seeking professional help. The physician must carefully assess these previous efforts of self-treatment, optimise them, and strategically use the increasing list of prescription medications for management.
