Probiotics for Irritable Bowel Syndrome
The study aims to investigate the effect of probiotics on IBS-patients symptoms compared to placebo, when given for 6 months.
By draw the investigators give IBS patients, in the age of 18-50 years, capsules with either probiotics or placebo. The patients are to take 2x2 capsules / day for 6 months. The patients are followed for 1 year. They are seen after 3, 6 and 12 months, and are followed by means of monthly letters.
The capsules contain 3 different probiotic strains - Lactobacillus paracasei ssp paracasei F19, Lactobacillus acidophilus La5 and Bifidobacterium Bb12. The dose is 2 x 109 - 10 x 109 CFU/capsule.
The hypothesis is, that there is a clinical difference between the group receiving probiotics and the group receiving placebo.
