After getting the results of my bloodwork back, my gastro doctor suspects I may have something called Celiac Sprue (http://www.csaceliacs.org/). If it is what I have it will be a pain in the neck to adjust because I will have to adopt a gluten free diet.. forever. It's not curable at this point in time.
My colonoscopy was normal so this is a good thing. Next up is an upper endoscopy to see if my small intestine is damaged from the Celiac disease. Personally, I rather hope it's not what I have but at the same time, I'll be happy for a diagnosis.
