The next time you’re at the supermarket or in a theatre or any crowded place, look around you and consider this: About one out of every five people may be experiencing abdominal pain.

More specifically, about 20 percent of the population experiences irritable bowel syndrome (IBS), with irritating symptoms such as diarrhoea, constipation, gas and bloating.

Hopefully you aren’t one of those one-in-five. But if you are (or know someone who is), then you’ll be interested to know that a long-time researcher of irritable bowel syndrome symptoms believes that the last symptom on that list – bloating – may be the key to understanding one of the primary causes of irritable bowel syndrome symptoms, which could lead to more effective treatment.

Uncomfortable expanding
Without knowing anything else about it, when you see the term ‘bacterial overgrowth,’ you know that something not very good is afoot.

Dr Henry C. Lin, is a gastrointestinal specialist and an associate professor of medicine at the University of Southern California in the US. For well over a decade, Dr. Lin has devoted his research efforts to finding a single factor that might tie together the symptoms of irritable bowel syndrome. He now believes that bacterial overgrowth may be that factor. And the key is bloating.

Over the years, Dr. Lin noted that almost all of the irritable bowel syndrome patients he treated reported post-meal bloating. This prompted him to focus his research on gas caused by gut bacteria that ferments food in the intestinal tract. Bacteria perform useful functions in the large intestine, but Dr. Lin suspected that the bacteria might be migrating to the small intestine, triggering gas, bloating and flu-like symptoms that often accompany irritable bowel syndrome.

After a breath-test study indicated that a large majority of irritable bowel syndrome patients experienced small intestinal bacterial overgrowth (SIBO), an antibiotic trial helped confirm the results. In that trial, IBS patients received either an antibiotic or placebo. About 75 percent of the subjects who successfully eliminated SIBO with antibiotics reported a significant improvement in irritable bowel syndrome symptoms.

Good guys vs. bad guys
The use of antibiotics in Dr. Lin’s study may have been helpful in demonstrating how bacteria play an important role in prompting irritable bowel syndrome symptoms, but that doesn’t necessarily mean that the best course of treatment is antibiotics (which are already over-prescribed, making some of them ineffective against certain bacteria).

I asked HSI Panellist Dr Allan Spreen, to take a look at Dr. Lin’s study. He told me he wasn’t aware of the theory that connected bacteria to irritable bowel syndrome, but found it to be reasonable. In an email he wrote: ‘I do feel there’s something to the research; I just hope it doesn’t mean a quickie, antibiotic-related ‘cure’ is coming.

Antibiotics, of course, might help to immediately lower the ‘bad guy’ bacteria count, and therefore help a person feel better, while simultaneously killing ‘good guys’ and causing more trouble down the road.’

In several e-alerts, Dr. Spreen has written about the necessity of probiotic organisms. In a healthy individual, these beneficial bacteria inhabit the digestive tract in massive numbers, crowding out harmful bacteria, aiding digestion, and supporting immune function. This healthy ‘gut flora’ produces valuable nutrients (including certain B vitamins and omega-3 fatty acids), digestive enzymes like lactase, and immune chemicals that fight harmful bacteria and even cancer cells.

But this critical ecosystem is fragile and easily disturbed. For instance, poor nutrition, steroid drugs, chemotherapy and some types of antibiotics can completely kill off the beneficial bacteria in the gut. And when the number or activity level of your good bacteria drops too low, it opens the door for harmful bacteria to proliferate, allowing the opportunity for diseases such as irritable bowel syndrome to develop.

Striking the balance
I asked Dr. Spreen if Dr. Lin’s research might indicate that probiotic supplements would be a good treatment for irritable bowel syndrome symptoms, and he replied, ‘I absolutely would be giving probiotics for such a problem, along with any agents that might assist strengthening the intestinal wall, such as FOS (fructo-oligo-saccharides), which helps the ‘good’ bugs to re-establish, aloe juice, which has a long history of calming bowel problems, essential fatty acids, and digestive enzymes (which are usually under-produced in such situations).’

Just one question: Fructo-oligo-WHAT? This was a new one to me. But a little research revealed that FOS is simply a natural fruit and vegetable fibre that promotes the growth of beneficial bacteria.

Meanwhile, sufficient amounts of intestinal flora can be maintained through dietary sources such as cultured products (yoghurt and kefir), and lignans (flaxseed, carrots, spinach, cauliflower, broccoli, millet and buckwheat). But while the digestive tract can be ‘re-colonised’ by introducing enough good bacteria to overpower the bad bacteria, dietary sources alone can’t provide organisms in the vast numbers required to correct a serious imbalance. For this, a high-potency probiotic nutritional supplement is necessary.

But one word of caution: Bacterial imbalances in the intestine should not be taken lightly. So talk to your doctor or a health care professional before using a probiotic supplement to address irritable bowel syndrome symptoms or any other chronic digestive problems.

    People really do need to learn to love their bowel. It’s such an important aspect of good health and wellbeing. People need to get over the embarrassment factor and be mature and confident to go seek medical advice when they have problems with their bowels, bums and digestive tract. A lot of people don’t do this and as a consequence conditions that could be dealt with easily by early intervention are left to much later when it is more difficult and more expensive to treat. Simple bowel health tests are readily available, your doctor can do them. I think in the UK there is a free screening test available if you are over 50.0
