I suffered from IBS of varying degrees (beyond horrible to the point of not being able to leave home to mildly annoying) for 25 years. Dr.s prescribed meds, sent me to dietitians, prescribed more meds, did acupuncture, more doctors, more meds. FINALLY through an odd set of circumstances I found a dietitian in my area that does MRT testing followed by the LEAP nutrition protocol. It was expensive to do (approximately $1150) but worth every penny. I was tested for approximately 160 things from food stuffs to some chemicals and metals to determine my reactivity to different things. I worked with my dietitian to figure out how to proceed. She helped me interpret the testing and see how to make this information work in my life. That was last August. Since then my GI tract has calmed down. I have had very, very few episodes of IBS, my anxiety is lessened to almost nothing, my arthritis has cleared up and my brain fog has lifted, no GERD, no diverticulitis. I also lost weight, which I needed to do. I have more to go on the weight, but I will get there. At first the program was very hard, but I stuck with it and it has absolutely changed my life.
