Quality of life in different gastrointestinal conditions

Abstract

In recent years, there has been increasing interest in how gastrointestinal symptoms relate to and impact on patients' health-related quality of life. This is particularly the case for functional gastrointestinal disorders that are characterized by a lack of biological markers for disease activity. There is only a slight variation in the type of gastrointestinal symptoms reported with different gastrointestinal disorders, and patients with dyspepsia or irritable bowel syndrome, for example, often describe a variety of gastrointestinal symptoms with considerable overlap between them. The same pattern has been observed in patients with gastroesophageal reflux disease, even though heartburn and acid regurgitation are easier to distinguish from other gastrointestinal symptoms, particularly in patients in whom objective reflux is verified. Most aspects of health-related quality of life in patients with gastrointestinal disorders are compromised, irrespective of diagnosis. Patients with functional disorders seem, if anything, to display more emotional distress than those with organic disorders. Given the considerable overlap between different gastrointestinal symptom clusters, it is not surprising that these conditions have a similar impact in terms of perceived health status and quality of life. The key factors associated with the degree of perceived distress and dysfunction relate to disease severity and the presence of abdominal pain symptoms.
