Chronic constipation in Adult
Constipation can be asymptomatic or can cause pain with defecation, chronic abdominal pain (often left lower quadrant), abdominal distension, and the sensation of incomplete fecal voiding. Fewer than 3 bowel movements per week can be categorized as constipation, although bowel frequency is an unreliable marker as a patient's baseline frequency varies widely among the general population.
A thorough history can help elucidate any implicated medications or systemic disorders that can cause constipation.
