The weight loss is intriguing. Do you suffer with a bloated stomach/intestines? Is your appetite weak or strong?
Have you tried probiotics? Did you get any weird symptoms with probiotics?
Candida can cause a real digestive war to happen when you introduce probiotics initially. parasites can cause extreme weight loss, with a ravenous appetite. parasites can cause nosebleeds.
I know a chap who had candida and suffered with non-stop sinus issues. But he never lost weight - if anything he gained weight. It apparently is more of a candida symptom in men than women.
Yet as another recent thread suggested - candida and endocrine, adrenal problems seem to go hand in hand...along with metal toxicity etc, So i'm not saying it's just candida....but the candida could cause your brain fog symptom.
