Yes! I have a very positive story to share!
Last summer my 13 year old son suffered a ruptured appendix and was in the hospital for six weeks. During that time he was on massive doses of several different kinds of antibiotics.
While the antibiotics helped to save his life, they wiped out the good bacteria in his gut and allowed C-Diff to proliferate. Just when he was released from the hospital for his appendix, he had to go back in because of the C-Diff.
Like you, I looked it up on the Internet. Big mistake. I was no longer fearing the ruptured appendix would kill him... now I was fearing the C-Diff would kill him.
Ironically, it took another antibiotic to knock out the C-Diff but I am delighted to report that
he never had another problem with it again. His digestive system has been fine ever since.
I tried to boost his good bacteria by giving him probiotics every day. Yogurt is good, of course, but there is a specific strain that is particularly helpful for C-Diff. I'm sorry I don't remember which one, but you can figure it out via Google and purchase it online.
Best of luck to your dear daughter and many (((hugs))) for you. I know how scary it is when there is something potentially seriously wrong with your child. Please keep us posted as to how she is doing.
