I'm glad you're feeling better. Even though there is not cure found yet for metabolic body odor, there is an opportunity to gain some control over its intensity by researching and understanding the management protocols suggested by the experts. So, I'm glad to see that you have been reading and researching yourself! :))
About the differences between Leaky gut syndrome and Irritable bowel syndrome, I am no expert by no means on either of these two topics, but perhaps some of these articles can shed some light on your question.
According to Leaky gut syndrome from Wikipedia, http://en.wikipedia.org/wiki/Leaky_gut_syndrome
“Leaky gut syndrome
is a diagnosis prevalent in various branches of alternative medicine
… can lead to increased permeability of the gut wall to toxins, microbes, undigested food, waste or larger than normal macromolecules… While many practitioners maintain that leaky gut syndrome is a bona fide medical condition… remains controversial and scientifically unsettled.”
remains controversial and scientifically unsettled.
In an article published in About.com:Alternative Medicine
, entitled Leaky Gut Syndrome/Intestinal Permeability, http://altmedicine.about.com/od/healthconditionsdisease/a/TestLeakyGut.htm
it discusses the standard test for leaky gut syndrome by Lipski, E. Digestive Wellness, Keats Publishing/McGraw Hill, 2001.

The Mayoclinic.com http://www.mayoclinic.com/health/irritable-bowel-syndrome/DS00106/DSECTION=3
has an article entitled irritable bowel syndrome, and under the ‘Causes’ page, it says, “No one knows exactly what causes irritable bowel syndrome. The walls of the intestines are lined with layers of muscle that contract and relax as they move food from your stomach through your intestinal tract to your rectum. Normally, these muscles contract and relax in a coordinated rhythm. But if you have irritable bowel syndrome, the contractions may be stronger and last longer than normal. Food is forced through your intestines more quickly, causing gas, bloating and diarrhea. In some cases, however, the opposite occurs. Food passage slows, and stools become hard and dry.”About.com:Alternative Medicine
also has an article entitled, Natural Remedies for Irritable Bowel Syndrome (IBS). http://altmedicine.about.com/cs/digestiveproblems/a/IBS.htm
IBS is more recognized by western medicine than Leaky Gut Syndrome. My niece, who is a nurse, and also has been diagnosed with IBS, explained to me that IBS is generally diagnosed after all other conditions have been ruled out. The treatment plan prescribed by her doctor that works well for her is a no ‘white foods’ diet, which would be white rice, potatoes, breads, milk, dairy products, etc., as well as no caffeine or sodas. She does eat fruits, yogurt, and some vegetables, whole grain foods, like all-bran cereal, brown rice, etc.
