Casein Intolerance Symtpoms- Extreme Thirst? in Related Issues & Disorders Posted February 9, 2012 · Report to Admin I found out that I had celiac disease a year ago. My symptoms were never too severe- just extreme bloating, gas, and embarrassing noises! Since going gluten free, my symptoms have completely subsided- I can now hang out with people after I eat and not be worried about my stomach! HOWEVER, recently, my symptoms have begun to flare up a bit. Definitely less severe, but they are the same symptoms that I have when I eat gluten. Another recent symptom is EXTREME thirst. I drink around 160 oz a day, and urinate very often because of this. I saw an endocrinologist but he didn't see anything related to hormones that would explain the extreme thirst. I am starting to see a pattern of the increased thirst after I eat milk products, such as ice cream. I'm worried that I may have developed a casein intolerance. My question for you all is: has anyone had the symptoms of extreme thirst related to a casein intolerance? And also, do you recommend I go on an elimination diet to make sure it is dairy or should I just go see my GI? Are there any tests that they can actually perform? Sorry this is so long! Thanks so much!
