What is causing my symptoms?

The exact cause isn't known. Factors that appear to play a role include genetic background,environmental factors, diet, previous infection and changes in the gut microbiota. In particular, the diversity of microbial population is reduced and the microbiota shows the presence of an altered microbiota (also known as “dysbiosis”) in people with IBS and UC. These people showed a decreased amount of Lactobacilli and Bifidobacteria.


The right probiotics can help

VSL#3® is a probiotics mixture containing 8 different strains of probiotic bacteria which is specially formulated and processed for the dietary management of IBS, UC, ileal pouch.

Daily and long-term consumption of high levels of certain strains of viable protective probiotic bacteria in appropriate ratios is needed to maintain adequate and balanced colonization in the gastrointestinal tract of people with these conditions. This cannot be achieved simply by modification of the normal diet.
