A symptom-based approach is the best means for diagnosing chronic constipation. Extensive diagnostic testing is seldom necessary unless alarm features are present. Encourage routine colon cancer screening tests for all patients aged 50 years or older.
Increased fiber intake through diet or fiber supplements is an appropriate initial therapy for chronic constipation. Osmotic and stimulant laxatives may be administered to patients who do not respond to more conservative measures if the limitations of these agents are explained. Tegaserod, a selective 5-hydroxytryptamine type 4 (5-HT4) receptor partial agonist, is more effective than placebo at relieving symptoms of chronic idiopathic constipation in patients younger than 65 years of age. Patients with suspected defecation disorders and those with treatment-refractory symptoms should be referred to a gastroenterologist for further evaluation.
