Somatic Comorbidity in Chronic Constipation: More Data from the GECCO Study

Abstract

Background. Comorbidity in chronic constipation has rarely been investigated, despite the fact that constipation can occur as one symptom in a number of neurological, systemic, and other nonintestinal and intestinal disorders. Methods. Of 1037 individuals with constipation identified during a telephone survey, 589 returned a postal questionnaire with valid data, asking for sociographic data, clinical symptoms, comorbid conditions, medication intake, and health care behavior related to constipation. Among them, 245 reported some somatic diagnoses and another 120 regular medication intake. They were compared to individuals without comorbid condition and presumed functional constipation (n=215). Results. Individuals reporting a somatic comorbid condition and/or regular medication were significantly older than those with functional constipation (63.8±15.8 and 43.7±15.5 years, resp., p<0.001) and had lower health and social status (both p<0.001), but similar general life satisfaction (n.s.). Their quality-of-life was lower for the physical (p<0.001) but not for the mental health domain (n.s.), while among those with functional constipation, the mental health domain distinguished IBS-C individuals from those with functional constipation but without pain (p<0.001). Conclusion. In an unselected population sample with constipated individuals, those with a somatic comorbid condition outnumber those with functional constipation alone and are distinctly different with respect to age and health status.
