Not likely. Candida is in our bodies and when you take suppression meds it can become a problem...particularly with steroids. Some lupers have digestive problems but not everybody. The relationship has never been proven but there are doctors who push unproven meds and alternative treatments.
If it was that easy, researchers would have found it long ago and come up with a way to control candida.
The most likely explanation is that we inherit a set of genes that predispose our immune system to a disruption by something....chemical, virus, bacteria, who knows. It is a complex mechanism and that is why it is so difficult to understand. new avenues of genetic research will eventually open the door by exposing what is deficient in the genome of lupers and others with AI diseases. once that is understood, treatments can be devised. Right now nobody understands the mechanisms and some are just throwing darts.....sometimes just to make money on treatments that don't work.
