"Functional Bowel Disorder. Investigation in General Practice"

The study aims to investigate how to give the diagnosis of Irritable Bowel Syndrome. The investigators compare two parallel groups of primary care patients, in the age of 18-50 years with gastrointestinal complaints where the GP suspects IBS. All included patients fulfil international diagnostic criteria (ROME III) and have no danger signals. Group 1: The diagnosis is based on the diagnostic criteria and few blod tests Group 2: The diagnosis is a diagnosis of exclusion after investigations with extended blod tests, examination for milk- and gluten intolerance, stoll for ova and parasites and scopy of the intestine. After receiving the diagnosis of Irritable bowel syndrome all patients are informed about the condition. The investigators follow the patients for 1 year. The investigators hypothesis is that the two investigation programmes (group 1 and 2)are equal with respect to the patients´ quality of life, symptoms and satisfaction and also with respect to finding of organic diseases.
