Even though stress may not directly cause IBS, it may change brain-gut interactions and cause intestinal inflammation which could be the cause of pain in the abdomen, appetite loss and diarrhoea, a recent study by researchers at the University of Michigan Health System found.
Stress does suppress a crucial component called inflammasome, required to maintain normal gut microbiota, and in this area, probiotics was found to be beneficial in reversing the effect in animal models.
"The effect of stress could be protected with probiotics which reversed the inhibition of the inflammasome.This study reveals an important mechanism for explaining why treating IBS patients with probiotics makes sense," researchers said.
The gut bacteria have a huge role in controlling pathogens in the body, aiding digestion and improve the absorption of nutrients. Gut bacteria help in strengthening the immune system.
