The Candida Autism Connection – Why Fluconazole doesn’t work

Fluconazole autism candida autistic


Most of the families that I treat report candida or yeast overgrowth as one of their child’s ongoing symptoms. In fact studies suggest that 90% of autistic kids have yeast overgrowth and other gastrointestinal issues. Many of these families have been trying to treat it unsuccessfully for years. Why is this? Well, I’ll tell you my theory below, why Flucanazole is not successful, and my approach to treating candida.


Is candida overgrowth ‘part’ of autism? Well, it depends what you mean by ‘autism’. Some people object if anyone (like me) claims to be able to ‘treat’ or ‘fix’ or ‘cure’ autism, or refer to it as an illness or disease in any way. To these people, autism is just a genetic trait, an example of ‘neurodiversity’ (this is the belief that things like Autism, ADHD etc are normal, natural variations in the human genome). The problem lies of course in the fact that the word ‘autism’ is an umbrella term that can refer to a wide variety of people. This is discussed in more detail in A Tale of Two Autisms. This post isn’t for these people.


Many families that come to see me have already spent years with Biomedical doctors. Their typical experience is:

  • Their child has autism and gastrointestinal issues so they go to the doctor.
  • Tests are carried out and the child is seen to have high levels of candida and other signs of gut dysbiosis.
  • Anti-fungal treatments such as Fluconazole are ordered, often causing uncomfortable die-off symptoms (Herxheimer reactions).
  • New tests are carried out, the candida levels are reduced…success!
  • However, a few months later the candida is back. More anti-fungals, more die-off…success!
  • But, then the candida comes back… This process can continue until the family realises these treatments aren’t resolving the problem.


We homeopaths see our bodies as dynamic, intelligent, self-healing entities that are always aiming to return themselves to balance. So instead of seeing our job as suppressing a symptom, we see that symptom as something the body is doing to rebalance itself…or something that is ‘least bad’ for the body. 


Measuring or focusing on the wrong thing could lead to the wrong outcome. I believe that giving anti-fungals to a child with candida overgrowth doesn’t work because the body is USING the candida as it’s ‘least-bad’ response to something. In other words, the candida has a purpose. What? Well…we are back to my old friend toxicity.


In my experience, candida overgrowth is indicative of metal toxicity. Candida will bind to metal molecules and so keep them out of our tissues and organs where they can wreck havoc. So what happens if we give anti-fungals in cases like this? The candida is killed & drops it’s load of metal into the bloodstream and you’ll get a so-called Herxheimer reaction – This is normally thought of as caused by the endotoxins released by the candida, but I believe it is a combination of these and the bodies reaction to the metals suddenly flooding it’s bloodstream. What happens within a few months? The body is STILL trying to find a ‘least bad’ solution to the metals which are still present, and so the candida is allowed to once again proliferate and we’re back where we started.


I’m not saying the candida is a good solution, there are obvious problems with it’s overgrowth: it releases endotoxins, ammonia, ethanol and other substances. BUT it’s better than allowing toxic metals to lodge in tissues in your brain!


So why is the allopathic approach wrong? Because they have measured (and so are attempting to treat) the wrong thing. The candida is the OUTCOME of having high metals in your body. Of course anti-fungals don’t work…they don’t touch the metals.


How I treat candida:


Often I don’t treat the Candida at all! I let it be, confident that once we have identified and removed the toxins (metals in this case), the body no longer will have need for the candida and the levels will normalise by themselves. Occasionally I also have to give homeopathic remedies like Medorrhinum, Lycopodium, Thuja or Candida Albicans in potency to help the body re-gain balance.   


For example, I might prescribe Poly Metals (a remedy containing lots of different metals) using my 8-week detox protocol. If the child needs the remedy, we’ll see a detox response similar to the Herxheimer reaction, followed by an improvement in their autistic symptoms (because, of course, the symptoms of metal toxicity can bear an uncanny resemblance to autism). I might then follow this with a bowel nosode to help the body’s microbiome regain balance as quickly as possible.

    Couldn’t agree more! A homeopath understands that there is an underlying imbalance for the candida overgrowth. The plan and strategy to correct the imbalance may vary from homeopath to homeopath and client to client. But, it is in the realization and understanding that simply going on a killing spree of the yeast is not going to restore health that half the battle is won… if you think of it as a battle that is.

      Lyme Disease causes autism and candida overgrowth. The disease uses heavy metals for biofilm (protecting itself from immune system etc). The disease is accompanied by co-infections such as parasites and viruses. Transmitted inutero, sex, blood transfusions, vaccines (infected animal cells), biting insects etc. An ancestor bitten by a tick pre pregnancy can pass the disease down through the generations. Igenex test for it (local tests not accurate). Join a Lyme facebook site for answers. Look up the Wiegman Protocol.

    How do you know if a child has metal toxicity? Are there screening tests?

    When my son took Thuja, his vaccine injection site scars went away. But he still has Candida overgrowth. May need to look into these remedies:)

    Alan!! You are absolutely awesome!!
    “the symptoms of metal toxicity can bear an uncanny resemblance to autism”.

    Nobody could have explained this better in layman terms.

    This gives me great confidence that my child is no longer Autistic and is only affected by heavy metal toxicity.With the remedies to address heavy metals, she can quickly heal herself and regain her potential.
