Probiotics and Intestinal Disorders

Studies have shown that an imbalance in the intestinal microflora may be an important factor in the development of symptoms for some individuals with IBS (Sartor, 2004). For example, the composition of the intestinal microflora may affect the ability of the colon to contract and relax. A recent study out of Canada described results related to probiotics and smooth muscle hypercontractability in an animal model of postinfective irritable bowel syndrome (Verdu et al., 2004). Studies have also explored the relationship between pain associated with IBS following regular consumption of probiotics (Saggioro, 2004; Si et al., 2004).
