brogers, I am not sure where you got the information you posted, but with all due respect it is totally inaccurate.
IBS is NOT and Infection and is NOT highly contagious and IBS is itself a distint clinical entity. Candida is in the gut in the first place to HELP fight infections. There is no evidence of it even being a problem with the immune system that is observed by immunologists. There are real candida infections which are rarer and can kill a person however. IBS is not an infection or caused by candida or yeast. In the above posts are accurate candida research and information. They are now sequencing its dna.
GaGa, IBS and CFIS and Fibro share common issues for sure but it is not candida and so you know the "candida overgrowth" that is being talked about here has never been found in anyone 20 years or so since it was first speculated on by someone who was not even a reasercher, by any gastroenterologist, neurogastroenterologist, immunologist,except basically on the internet and some unorthodox practioners.
It use to be in the past people would use the term IBS as a "catch all" diagnoses for any kind of digestive upset, but that is no longer the case.
It might help to watch these videos and one expert on Fibro and IBS is DR Lin Chang, so you know. Some people might not get the right kinds of treatments for there problems.
Antibiotics are killing all the good bacteria and that can open you up to some problems in protecting yourself. Antibiotics can be over prescribed and one common problem is C-diff infection. The gut flora usally returns to normal a couple weeks after taking most of them naturally however when a person really needs to take them.
These are very up to date and excellent information on IBS.
