Irritable Bowel Syndrome and Probiotics

Functional Bowel Disorders (FBD) are one of the most common bowel diseases in the United States. FBD include irritable bowel syndrome (IBS), functional bloating, functional constipation, functional diarrhea, and unspecified other functional bowel disorders.

Effective treatments for these problems have been limited and oftentimes they are thought to be related to psychosocial problems. Effective treatments are limited in these cases and only provide partial relief.

Lactobacillus acidophilus NCFM (L-NCFM) and Bifidobacterium lactis Bi-07 (B-LBi07)

A new study to be published in the Journal of Clinical Gastroenterology compared Lactobacillus acidophilus NCFM (L-NCFM) and Bifidobacterium lactis Bi-07 (B-LBi07) to a placebo to determine how symptoms responded in cases of patients with FBD and IBS. Patients were given either the active probiotics or placebo two times per day over an 8 week period of time. During and at the completion of the treatment the patients were evaluated for effects in quality of life, well-being, symptom relief, and treatment satisfaction.

Of the 60 patients 31 received the probiotic mix of Lactobacillus acidophilus and Bifidobacterium lactis and another 29 received placebo. At 4 weeks out improvements were noticed in the probiotic group over the placebo group especially in the amount of bloating. This continued until the end of the trial at 8 weeks, with improvement in the probiotic group over the placebo group in bloating.

The conclusion of the study supported the use of the probiotics L-NCFM and B-LBi07 in managing symptoms of bloating in patients with FBD and IBS. While the study found that bloating was the main symptom improved by the study, bloating is a common complaint effecting nearly 20% of Americans.

The probiotics were well tolerated in the study. Given the safety and effectiveness of these probiotics in FBS, further trials may be warrented to see if additional symptoms may improve with a longer term intervention.

  1. Great! Thank for information, I’m looking for it for a long time,

  2. My mother and sister both suffer from IBS. I have experienced minor symptoms in the past, but ever since taking probiotics regularly, I haven’t had any!!! I pass the information on to all my friends and several of them are now on probiotics also.

  3. Wow, I think we have a product here that does the same thing. It has lactobacilli and it removes or prevents bloating.

  4. Great article you’ve got here. This is very informative. We have probiotic products here as well and knowing the healthy effects of this, I think I’m going to start taking this.

  5. Hey There Jmontague,

I was just wondering if anyone had any tips of what to eat and what not to if they suffer from this as well, it’s quite embarrasing having to rush out of where i am to go to the toilet. Thanks :D
