I was diagnosed with C-diff and Colitis after months of D, fever, and overall sick feeling. My regular dr did a stool sample to test me for C-diff when I first told her my symptoms. Test came back negative. I was still very sick so I was referred to a GI Specialist who did a colonoscopy. He tested me for c-diff again and lo and behold i did have it! So, he treated me for the C-diff first and when that had gone away he started me on Asacol for the Colitis.
My GI Dr told me that the C-diff my have contributed to me getting the colitis. I may have had the c-diff for so long and didnt know it.
So, I dont know if C-diff completely caused my colitis or if it just made it flare up. But either way I was told once you have C-diff you are more prone to get it in the future. Either way, good luck to you. It was a lot of pain for me and wish anyone luck that is going throug it!
