Yeasts and Moulds. Two things we may relate to decomposing foods or dark bathrooms, yet both yeasts and moulds are a common infection within the human body.

Really, yeasts and moulds are almost the same thing. They both belong to the Fungus part of the plant kingdom, however yeasts are single celled organisms, where moulds are microorganisms.

So for the sake of this article, I’m going to group them together and call them ‘fungus’.

We all have colonies of fungus within our digestive tracts from the day we are born, particularly if we were born naturally and not via Caesarean.  In theory these are kept in check by both the ‘good bugs’ in our gut, and also held away from our bloodstream by our gut mucosal barrier.

But fungal infection can overrun a person of any age, particularly those who are immune impaired such as newborns, the elderly and the very stressed. Also worth noting is that there are several medications and chemicals which can destroy the gut mucosal lining, and therefore make you more susceptible to fungal infection – namely things like non-steroidal anti-inflammatories; Ibuprofen; Aspirin; Ventolin; Steroid medications; antihistamines and things like heavy metals and pesticides. I will also add in there that long term internal use of Essential oils can do the same thing.

Some of the most common presentations of fungal infection in clinic are things like Ringworm (a skin lesion/rash), tinea, athelete’s foot, and thrush. But aside from these highly irritating and prevalent symptoms, there are also a myriad of more subtle signs that can suggest you might have an overgrowth of fungus.

Recurring rhinitis, sinus or ear infections, extreme fatigue, mood swings, depression, brain fog, or even chemical or food sensitivities and hormonal imbalances, can all potentially suggest a fungal infection. If you pay particular attention, a person who has any of these signs after consuming a food that contains yeast, or if it seems to flare up if they are in a mouldy room or humid environment – chances are it could be a yeast or fungal sensitivity.

Fungal infections can also be acquired. Remember what I said about the ‘good bugs’ being able to hold it at bay? Well consider this scenario for a moment: Anyone who has been put onto antibiotics or Ventolin (for example) for a repeated dose or period of time, have all but destroyed their own colonies of beneficial or ‘good bugs’. So what can then develop is an increase in the population of fungal colonies, purely because they are now left unchecked.

So on the outset the persons’ symptoms seem to return, and the GP assumes that the infection was not successfully treated so they prescribe a second round of ABOs, or sometimes even a stronger one. The cycle continues to build.

Often in people this is where I start to see behavioural decline, and usually it is more prevalent in children. They become moodier, more fatigued or more depressed in nature, and with it usually comes a disruption in their sleep patterns, night terrors or sudden allergies to things they never reacted to before.

Generally speaking, the testing for fungal infections probably isn’t necessary. You can blood test for Candida albicans, or something like a Live Blood Analysis can also quantify the prevalence of fungus in the body. However when working with children, I try really hard to avoid the non-invasive tests where I can, and there are other options in Functional Medicine.

In clinic I will often use a Hair Mineral analysis on kids. Whilst this isn’t a direct line to a quantitative analysis of the fungus in a body, if there is a generally-low level of minerals, it is safe to assume that something is hindering the body’s assimilating capacity. Also, if there is a large spike in Copper on a Hair test, the possibility of a yeast/ fungal infection is high, because they encourage each other in the body.

A more quantitative way to check is by using a Bioscreen Stool test from Melbourne University. This one is strictly limited to Medical Practitioners, however it is probably my favourite in terms of investigating the numbers of yeasts and fungal colonies within the gut environment. (It also has the added benefit of revealing potential overgrowths of things like Strep. B and Enterococcus = two strains which should be in everyone’s gut, but can become superbugs in nature when encouraged the wrong way).

I tend to use this type of testing when the patient’s symptoms are quite profound- for example behavioural issues, or chronic fatigue. These are really things that need to be specific with treatment.

However in general, treatment at the right pace, with the right herbs and nutrients, as well as dietary interventions, will usually get you over the line. I would like to point out that it might be best to seek the help of a trained practitioner though, because a true fungal infection can generate a die-off period upon commencement of treatment, meaning that your symptoms may well get worse before they get better!

A few good places to start:

  • Avoid all foods containing yeast. Consider an Anti-Candida diet
  • Identify and eliminate any mould or damp within your home
  • Consider using/burning antifungal essential oils to help combat airborne spores
  • Raise your Zinc levels. Zinc is a natural antifungal
  • Saccharomyces boulardii (yes, this is a probiotic yeast, but it works to compete with the pathogenic yeasts for floorspace)
  • Antifungal herbs
