<<Disclaimer: Verify this information before applying it to your situation.>> Hi guys, Does anyone know if the immune system is affected by CD? I can't help but think it might be while the CD is undiagnosed and untreated because your immune system is getting starved like the rest of your body. And are celiacs at additional risk for being immunocompromised even if they stick to the diet? I'm not trying to scare anyone, it is just of interest to me as I have been sicker in the last 4-5 years (undiagnosed but knew bread bothered me) than in my whole life with colds, flu, urinary tract infections, and wonder if there is a link. I feel better already after 2 weeks on the GF diet and 1 week milk-free so I am hoping that my general health will improve in terms of fighting off infections. Curiously, many of my urinary tract infections failed to respond to antibiotics which were determined to be the correct ones to eradicate the particular bacteria. I have never found a DR yet who can tell me if this might be because my system isn't absorbing the drug in the small intestine (I know some drugs are systemic and others concentrate in the urine-the latter should be effective). I have had up to 5 rounds of different things and still had the infection. Well, enough about me....if anyone knows what part of the gut absorbs antibiotics such as Cipro and Noroxin I'd be pleased to hear. Sorry to embarrass anyone with the tale of my insides. ;) Lisa
