Hi Everyone, I got to this forum about 18 months ago because I had been so sick and the people here were so knowledgeable. It's actually pretty likely that some of the puzzle pieces that I've received from members here have contributed to my still tromping around on this earth. But that's another story. Early in 2012 my worst symptoms were (undiagnosed) histamine intolerance, my pulmonologist asked if I could fast, because a 3-day fast was really the only thing (he knew) that could reset the immune system with regard to allergies and sensitivities. Having a lifelong struggle with hypoglycemia, I told him no, and put it out of my mind. January 2014 He agreed with me that I have histamine intolerance. I showed him the articles, discussed the results of the elimination diet, and how the symptoms go away when I can avoid dietary histamines and return when they are reintroduced. We talked about testing, but neither of us knew of a lab that could assess active histamine and my subsequent search didn't turn up one. He was comfortable with the conclusion (a diagnosis) that I was histamine intolerant based on the repeated onset and cessation of symptoms coincident with histamine-containing foods. I'll get into symptoms (everyone seems to be different), and food lists (everyone seems to be different), my opinion as to why I'm no longer hypoglycemic, and whatever else later (think of them as flashbacks). But I need to start this today and work forward. Today I started re-testing foods after a 3-day fast. Today I ate one of my famous homemade cinnamon rolls and I'm still breathing. Celebrate with me Let the party begin! My plan is to continue testing foods and document the results here.
