                        Yes,  I developed DVTs years after diagnosed w/crohn's.  I've been on coumadin for about 5 years now.  I've been told that both problems are autoimmune disorders.  *where your body doesn't recongnise parts of itself and attacks.  My hemotologist at the time said they were probably related.  during a recent/current crohn's flair up, we tried some antibiotics that were known to increase INR so they made me decrease my coumadin, I ended up in the ER with a 0.9 INR and superficail bloodclot!  We can't get my crohns into remmission - ugh!  Let me know if you want any more information.  I drive my doctors crazy with questions!  HOPE you're doing ok.
