Yes, Leaky Gut is very real and yes you can be suffering from it without having IBS. Every person is a bit different from the other person as far as how Leaky Gut can effect them. I found my information at ThinkRite systems on what it is and how it effects everyone differently. I had Chronic Fatigue, Add and Anxiousness before I learned what was causing it and how to control it. My Chronic Fatigue, Add and Anxiousness all left after about 6 weeks after removing fooRAB I was intolerant too and took supplements that helped heal the gut lining. The thing was, I had no idea that by removing just a few fooRAB my body was struggling with could have such a huge effect on how I felt. I no longer suffer from the conditions I mentioned and now feel normal again. Hope that helps!
