  • IBS is a grouping of symptoms that include gas and bloating, abdominal cramping, and constipation or diarrhea, headaches, fatigue, brain fog.
  • People can find themselves rushing to the bathroom many times a day, and even planning their day around knowing they can never be too far from a toilet. 
  • Fortunately, using an integrative approach can provide answers and long-term relief.

Irritable Bowel Syndrome (IBS) is a grouping of symptoms that include gas and bloating, abdominal cramping, and constipation or diarrhea, headaches, fatigue, brain fog. Sadly, for many patients with diarrhea-predominant IBS, they find themselves rushing to the bathroom many times a day, and even planning their day around knowing they can never be too far from a toilet. 

IBS is a diagnosis of exclusion, meaning it is diagnosed after other conditions, such as irritable bowel disease (IBD), which includes ulcerative colitis and Crohn’s disease, has been ruled out. It affects 10-20% of the population at any given time with women affected three times more frequently than men. More than 2.2 million prescriptions are written annually for this condition. 

Tragically, women with IBS are three times more likely to receive a hysterectomy than those without IBS and also report more overall surgical procedures, such as appendectomies. The total annual costs (direct and indirect) of treating IBS in the United States is approximately $30 billion, excluding prescription and over-the-counter drug costs. Up to 75% of the economic burden is from having to miss work. Patients with IBS miss about three times as many days from work or school annually as people without this condition. Up to 3.5 million physicians’ visits each year are because of IBS symptoms.  

While many people suffer from years with IBS, what I found in my medical practice, and what the research supports, is that using an integrative approach can provide answers and long-term relief. And when people’s health improves, all the physical, emotional and physical costs also improve.

Food Allergies

Food allergies can contribute to IBS symptoms and eliminating them can lead to dramatic improvement. A systematic review of the role dietary allergies play in IBS, which was published in 2006 in the journal Neurogastroenterology and Motility, concluded that excluding dietary allergens can lead to an improvement in up to 71% of IBS sufferers. 

Blood tests for IgG antibodies and the allergy elimination-challenge protocol are most sensitive at detecting food intolerances that contribute to IBS. In an elimination-challenge protocol, patients follow a hypoallergenic diet for a prescribed period of time and track their symptoms in a journal. Then they methodically, and with guidance from a clinician, reintroduce foods one at a time. If symptoms return with specific foods, those are eliminated from their diet altogether, perhaps not forever, but for a while. 

While the allergy elimination-challenge protocol is the gold standard for detecting food allergies, my experience is that the vast majority of patients cannot complete the protocol. Instead, they may make the mistake of challenging themselves with something that is not a pure representative of a food. For example, when challenging wheat, a person would have to eat pure wheat; not a piece of bread, which contains other ingredients. Additionally, the elimination-challenge protocol can take months to complete and is so restrictive that most people cannot follow it for that long. 

The more clinically relevant approach is the IgG food allergy test. For children, I would order an IgG 30-food allergy panel. In this panel the sample is obtained via a fingerstick, thereby avoiding the trauma to the child of a full venous blood draw. 

For adults, I would order a serum IgG 90-food allergy panel. These tests, while not conventionally ordered, are more relevant to IBS and other delayed-type hypersensitivity reactions than an IgE blood test. 

One of the most common misunderstandings among patients is when they say that their doctor had already tested them for allergies, and they were negative. However, nearly every time when I asked about this, the previous test was an IgE test, which can be negative when an IgG test is positive. You can always request your doctor order an “IgG food antibodies panel.” 

Intestinal Infections

The symptoms of food allergies and intestinal infections are so similar that I often found it best to rule out both food allergies and intestinal infections at the same time. The best tests for intestinal infections are ones that test for the three major categories of critters that can cause problems—bacteria, yeast (fungi) and parasites. I would order a stool test that looks at all three simultaneously, which typically required using a non-conventional lab. If there was an infection, getting rid of the offending organism often provided quick relief. 


A 2007 consensus statement published in the journal Digestive Diseases concluded that most cases of IBS are “post-infectious” and respond to probiotics. Probiotics are beneficial gut bacteria and have been studied in multiple clinical trials of IBS.

In a randomized, double-blind, placebo-controlled trial of 49 people with IBS, volunteers were administered a multispecies probiotic (B. longum, B. bifidum, B. lactis, L. acidophilus, L. rhamnosus, and S. thermophilus) twice daily for four weeks. The probiotic combination provided substantial relief to 68% of people who took it, compared to only 37.5% who took the placebo. Specifically, abdominal pain was reduced an incredible 75% in the probiotic group compared to those not taking the probiotic. People taking the probiotic supplements also experienced a significant 40% decrease in abdominal bloating and a 34% decrease in abdominal discomfort.

A randomized double-blind placebo-controlled trial evaluated the effectiveness and safety of multi-strain probiotic in 51 adults with diarrhea-predominant irritable bowel syndrome (IBS-D). The volunteers were randomized to take five billion CFU per day of a probiotic mixture comprising different strains of bacteria from the prior study. They took Bifidobacterium. breve, Bifidobacterium longum, Bifidobacterium lactis, Lactobacillus rhamnosus, Lactobacillus paracasei, Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus plantarum, and Streptococcus thermophilus.

After eight weeks of taking the probiotic, 100% of the volunteers who initially rated their GI symptoms as severe said they were no longer severe. The number of people rating their IBS as moderate dropped by 52% and the total IBS symptom score decreased by an incredible 49%. These changes were significantly greater in those taking the probiotic compared to the control group.

Peppermint Oil

Enteric-coated peppermint oil has also been shown in a clinical trial to decrease pain in children with IBS. In this clinical trial, 42 children received peppermint oil capsules that didn’t dissolve until they were in the lower intestines (enteric coated) for 2 weeks, at which time 71% of the volunteers in the peppermint oil group reported improvement in symptoms compared with 43% in the placebo group. 


Stress can exacerbate IBS symptoms, so it’s not surprising that meditation has been shown to help. In a 2001 study published in the journal Behaviour Research and Therapy, meditating 30 minutes a day for six weeks significantly decreased diarrhea, bloating, flatulence and belching in one study. 

Additionally, 23% of the participants had decreased headaches, 23% had decreased backache, 8% had less TMJ discomfort, 8% had a decrease in their high blood pressure, 8% noted improvements in their sleep and 31% had less “jumpiness.” Many also reported increased enjoyment in life (46%), energy (39%), and concentration (31%), while also reporting less worry (31%), depression (31%) and anxiety (39%). For those who practiced meditation, 86% experienced improved symptoms. Not surprisingly, there were no side effects.
