Can Probiotics Help Calm IBS?

Recent studies offer evidence that probiotics help calm IBS, also known as irritable bowel syndrome. Rebalancing the microbiota of the gut may do the trick.

Irritable bowel syndrome (IBS) has long mystified doctors. Gastroenterologists classified it for years as a “functional” gastrointestinal problem, by which they meant they could not find anything wrong with the digestive tract. Nonetheless, people with IBS suffer real pain, bloating, cramps and diarrhea or constipation. Recent research has shown that bacterial toxins may play an important role in the development of these symptoms. Some people have reported that eliminating certain foods from their diets can reduce symptoms. Others have found that probiotics help calm IBS.

Do Probiotics Help Calm IBS?

Q. For over 15 years, I suffered from IBS that caused gas attacks, flatulence and diarrhea. My doctor told me that there was nothing that I could do to stop these symptoms.

On my own, I decided to see if avoiding all dairy products would help. That did make a difference.

Then I had to take an antibiotic that gave me constant diarrhea. I decided to try taking a probiotic that offered over 30 billion live intestinal bacteria daily. Within two weeks, my diarrhea stopped. Now, four months later, I can eat anything, including dairy products, without diarrhea, gas or bloating.

Evidence That Probiotics Help Calm IBS:

A. Since irritable bowel symptoms appear to be linked to changes in gut microbiota, researchers have been considering how they could improve the balance of microbes (Current Opinion in Endocrinology, Diabetes, and Obesity, online Nov. 27, 2019). In light of this, scientists analyzed nine placebo-controlled studies of probiotics for symptoms of irritable bowel syndrome (World Journal of Gastroenterology, March 14, 2015)

They concluded:

“Probiotics reduce pain and symptom severity scores. The results demonstrate the beneficial effects of probiotics in IBS patients in comparison with placebo.”

While that study did not specify which probiotic species might be most useful, another study did. Indian investigators found that Saccharomyces cerevisiae CNCM I-3856 at a dose of 2 billion CFU twice a day for eight weeks reduced pain and improved stool consistency (International Journal of Colorectal Disease, Dec. 5, 2019). In summary, this randomized controlled trial offers very promising evidence that probiotics help calm IBS.
