The following paragraph on Heather’s web site caught my eye:
Irritable Bowel Syndrome (IBS) Supplements
Supplements for the dietary management of IBS can be unbelievably helpful for stabilizing digestion. This is particularly true when they’re used as one of the five key strategies for controlling Irritable Bowel Syndrome (proper diet, stress management, alternative therapies, and prescription medications are the other four).
Soluble fiber supplements, herbs that have medicinal effects on the gastrointestinal tract, heat therapy, probiotics, calcium and/or magnesium, and digestive enzymes are all of proven benefit. Best of all, results are usually felt very quickly - sometimes even immediately (emphasis mine). ((1 from the Help for IBS Website
Not to throw a wet blanket on your hopes of instant relief–well, yes, I’ll throw that wet blanket after all.
Starting diet change, discovering that indeed there are more triggers than you thought, finding the right supplements, all take time. It took me at least three months. Then, too, probiotics take at least three weeks before they begin to give relief. So IBS treatment in full does not produce rapid results. Yes, parts of a treatment regimen do, such as putting a heating pad on a painful tummy, or drinking fennel tea for gas and bloating. Getting IBS under control, though, takes time.
