How can probiotics affect irritable bowel syndrome and gas?

ANSWER

One theory about irritable bowel syndrome (IBS) is that the normal blend of helpful bacteria that live in the intestines has been disrupted. Some of them make more gas than others as they help break down your food. People with IBS may have too much of those types of bacteria.

Probiotics are supplements that add bacteria to the digestive system to bring back the right balance. Studies on taking probiotics for IBS show some promise.
