Anchor 1

A year after being diagnosed with IBS, I made a breakthrough observation when I connected my IBS symptoms to garlic ingestion. I investigated by performing a patch test with garlic on myself and found that my allergy to garlic was detectable by this test. I then removed this single food from my diet and was able to completely stop my IBS symptoms.

​

I discovered that the allergies detected by patch testing could cause IBS symptoms. The allergies detected by patch testing are physiologically different from allergies detected by skin prick tests and commonly ordered antibody blood tests. These latter tests have generally been determined not to be helpful for IBS. The IBS-80 patch test tests for 80 common food allergies associated with IBS.

​

​

I don't want to get too far into the weeds here, but if you're interested, here's how I identified the cause of my IBS symptoms.

​

Once I realized the connection between garlic and my IBS symptoms, I dug in deeper, investigating with three scientific studies (Study 1Study 2Study 3) showing that many other food allergies detectable by patch testing also cause Irritable Bowel Syndrome. Foods used in the studies are now the backbone of the IBS-80 patch test. The theory is that an allergic reaction similar to that in the skin caused by the food(s) used in the patch tests also occurs in the intestinal lining after ingestion of the same food(s), triggering the IBS symptoms.

​

​

Our patented proprietary test allows many patients to exit the trial and error game

and zero in on the root causes of their symptoms — and eliminate them from their diet.

 

The Food and Drug Administration (FDA) has not evaluated IBS-80 for safety or effectiveness.

Patient Testimonials

We had all the tests done (on my daughter) - endoscopy, colonoscopy, allergy testing. Everything came back negative. They told me that it would just take time to figure it out. No one had an answer for me. No diets worked. Nothing I eliminated seemed to keep my daughter well for very long. Dr. Stierstorfer took the time to contact me directly and tell me what makes his test different. When the results came back, I could finally connect the dots. They found the needle in our haystack and the answer to our problem. It wasn't the gluten but the bleaching agent used in flour and a natural substance in carrots, celery, and parsley.  She has not had one IBS symptom. Not even a stomachache. I simply removed the few things from her diet that had come up positive.
