CANDIDA: The cause of your terrible gut health and fatigue that your doctor has no idea how to fix.
Here’s how to know if you have it, what causes it and what to do about it:
Image
◇ A coated tongue (more towards the front)
◇ IBS
◇ Crohn’s or UC
◇ Bloating
◇ Brain fog
◇ Gas
◇ Nausea
◇ Constipation
◇ Diarrhea
◇ A lack of appetite
◇ Fatigue
Are all signs of a fungal overgrowth, the most common of which is Candida.
Image
Unfortunately, testing for Candida can be a futile effort.
Common testing methods are:
Candida antibodies (IgG, IgM, IgA): Tests the presence of immune proteins that recognize Candida in the blood. Indicative of exposure, but can also indicate past exposure (not present) and not telling whether or not it is causing your symptoms.
Stool: Tests the presence of yeast (or Candida) in your p**p. In theory this is the best, but not indicative of Candida in the upper part of your digestive tract, and also not indicative of Candida in the lining (mucosa) of your gut, just in the p**p. Candida also normally exist in the gut without causing problems, so again, not telling whether or not it is causing your symptoms.
Aspirate: Tests the presence of Candida in the juice of your small intestine. Not indicative of what is happening in the lower gut, and also rarely done in practice.
Since testing is so unreliable, going off of symptoms is really the best strategy.
HOWEVER, this can backfire if you are not careful, for reasons I will explain later.
Candida can be behind IBS - antifungals can reverse it.
Candida can drive inflammation, gas and other processes in the gut that contribute to IBS pathology.
People with IBS have higher levels of this fungus,
but treatment with fluconazole or nystatin can improve symptoms.
Image
Candida can cause inflammation in the gut - antifungals can reverse it.
Noticing a pattern?
Inflammation and poor gut health can cause Candida overgrowth,
and Candida can cause inflammation and ruin gut health.
So, how can we stop this cycle?
Image
We all have Candida in our guts to some extent.
Issues arise when it starts contacting or invading our cells, or worse - passing through the gut.
This becomes more likely with:
◇ Bacterial overgrowth / dysbiosis
◇ Suppressed immunity
◇ Chronic gut inflammation
Image
Image
That means in order to solve Candida, you MUST nail down the basics of your gut health,
before thinking about anything specific for it.
I went into the most important needle-movers for gut health in great detail here:
ESTROGEN is one of the key promoters of Candida.
This is why yeast infections / UTIs are common in women, especially during high estrogen portions of their cycle or during pregnancy.
If you have Candida, you MUST focus on lowering estrogen.
Image
Progesterone is an anti-fungal.
Progesterone is our endogenous anti-estrogen hormone,
and it counteracts the fungus promoting properties of estrogen.
Progesterone was shown to reduce fungal biofilm formation and invasion.

I've written about the benefits of progesterone (+ how to supplement) here:

Low stomach acid and a slow gut can cause Candida overgrowth.
Stomach acid is our primary defense against excess microbial growth - bacteria and fungi like Candida.
If your gut motility is slow, then you just leave the microbes more time to linger and feast.
Image
Some tools to help improve motility:
◇ Coffee (even decaf)
◇ Senna
◇ Raw carrot
◇ Magnesium
◇ Baking soda
◇ Cascara
◇ Triphala
◇ Sodium butyrate
◇ Mastic gum
◇ Vitamin B1
Candida thrives in an environment rich in simple sugars.
HOWEVER, the real problem is CHRONICALLY high blood sugar - in other words insulin resistance.
People with poor glucose metabolism are susceptible to fungal overgrowth.
Image
Adding tons of refined carbohydrates to the diet does not lead to Candida overgrowth.
This is likely because most simple sugars get absorbed rapidly, before Candida gets a chance to feed on them.
Image
There is some evidence to suggest a lower simple sugar diet can help in some people, when combined with antifungal drugs.
Image
The immune system needs carbs to kill Candida
Candida can outcompete the immune system for carbs, leading to impaired immune defense,
but giving a sugar drink improves survival in animals after infection.
If the low carb approach isn't working, it might not be worth it.
Image
Another protective factor is secretory IgA.
This is an antibody that lines our mucosal tissues and essentially binds up and neutralizes pathogens like Candida.
Interestingly, RAW MILK (or colostrum) actually contains intact IgA proteins that our bodies can use.
Image
IgA and immunity in general are known to be impaired by stress.
Lowering stress is going to be absolutely vital if you have Candida.
Vitamin D is a powerful anti-fungal agent.
Vitamin D is absolutely vital for a fully mature and functioning immune system.
It also produces proteins that are directly antifungal.
It reduces all forms of Candida growth, virulence and biofilm formation.
Image
Sulfur is a key antifungal.
Elemental sulfur (flowers of sulfur or sublimed sulfur) can be used in small amounts as an antifungal agent.
This is the reason sulfur is in many skin products - due to its antifungal properties.
Image
L. Rhamnosus is a key antifungal.
This is a probiotic that can produce various antifungal metabolites.
Lacto / bifido bacteria (in probiotics) in general tend to outcompete and are protective against fungal overgrowths.
Image
Probiotics can rapidly reverse Candida.
Here, a lacto/bifido blend reduced Candida substantially just within a few weeks.
Image
Lactoferrin is an antifungal against Candida.
Lactoferrin is a protein found in milk (especially raw milk and colostrum) with various protective benefits for the gut.
It helps chelate IRON which is important for all pathogens to grow, including fungi like Candida.
Image
Some other antifungals:
⇨ Methylene Blue
⇨ Pau D'arco
⇨ Niacinamide
⇨ Aspirin
⇨ Oregano oil
⇨ Rosemary
⇨ S. Boulardii
⇨ Coconut oil
⇨ Raw honey
⇨. Zinc
⇨ Grapeseed extract
You also can use prescription antifungals,
and while these are more powerful for killing the fungi,
they can ruin the microbial environment in the gut and the immune system.
This would be my last resort once the above resources are exhausted.
Image
The thing is, while Candida is highly publicized and talked about,
most gut issues are bacterial in nature.
It is much less common for issues to be driven by Candida than by bacterial dysbiosis,
and even if they are - the bacteria control Candida's proliferation.
Since tests can be misleading or a waste of money and time, I would focus on fixing the bacteria in the gut before thinking about Candida.
The symptoms can be identical, besides a few differences.
