More evidence that IBS is not all in your head: A recently published research endeavor sought to find out if there are bacterial differences among people with various IBS sub-types. In order to do this, "fecal microbiota" taken from volunteers were analyzed on three separate occasions, according to the study abstract . The sample size of the study was small, with eight IBS-D patients, eight IBS-C patients, four IBS-A patients, and fifteen control individuals.

The samples were then subjected to a biological inquiry process to determine the "ribosomal RNA (rRNA) gene phylotypes". Honestly, I don't quite know what that means, but it appears to be a way of quantifying the bacteria types. The important finding is that there were significant differences in the types of bacteria found in all of the four groups of individuals. The researchers conclude that their study emphasizes the "possible contribution of the gastrointestinal microbiota in IBS."
