I've suffered from hearing loss for years and it's been getting worse. Now I'm sure candida is at the root of it. Plus, I had a bunch of other candida-related symptoms - foggy mind, itching, cold feet, tinnitus, and other stuff, including the usual leaky gut and zits.
If it helps anyone, I found that tackling Candida with herbal cleanses, but also by cutting out wheat and other yeast-promoting things from my diet - even reducing salt intake, made a radical difference.. My doctor told me it was about age. That's not true, and my hearing has slowly been coming back - right ear first, then left ear. The other symptoms have reduced too. So there's something to this.
I've been writing blog posts about it, containing information you might find useful.
