Candidiasis

Candida albicans is a yeast organism that's present virtually everywhere. It's a normal part of the human intestinal tract and general body environment.

In most cases, the balance of PH, digestive enzymes, beneficial bacteria, and other factors prevents Candida or any other single organism from taking over and causing health problems.

Scientists and doctors agree that an excess of Candida can, especially in cases of suppressed immunity or other predisposing factors, lead to illness. Candida is the cause of many illnesses like thrush, athlete's foot, "yeast infections" and more.

However, it is highly debatable whether Candida directly causes widespread vague illness in a large percentage of otherwise healthy people.

#############

The questionnaires, symptom lists and most of the tests available that purport to identify a Candida problem are not particularly reliable or specific.

A test that shows excessive Candida in urine, for example, may point to a yeast infection of the bladder but does not necessarily indicate a systemic (whole-body) Candida infection. Too, the more common localized yeast infections may not be adequately treated by taking antifungals orally and making dietary changes.

Remember, everyone has Candida. The question is whether it's causing disease or not.

With the exception of clear fungal infections such as thrush and other yeast infections, in most cases the same pattern of symptoms is equally likely to occur as a result of one or more other factors besides Candida. Even in the case of true Candida-caused illness, the commonly-recommended treatments are not appropriate for everyone.

Even unrelated issues may seem to improve on the antifungal treatments, yeast-free diet, and the general healthier lifestyle being promoted. However, in many cases it is still important to consider the possibility that yeast may not actually be causing some or all of the symptoms. Or, even if yeast is causing symptoms, it could be a secondary issue that won't truly be solved until the underlying problems are treated.

I believe that these quizzes, tests, and the strong encouragement of self-diagnosis and treatment do sometimes result in symptoms of other disorders being blamed on Candida. In many cases this can be truly dangerous, such as when allergies, diabetes, thyroid dysfunction, malnutrition, cancer or celiac disease are the true cause of the symptoms.

There has been much research in the scientific community about all different aspects of Candida, systemic candidiasis, possible causes, variables and treatments. But nothing has been really conclusive so far when it comes to these kinds of non-specific generalized illness being caused directly by Candida.

It's not for the lack of trying; the research just doesn't show a clear causative connection. The research also does not seem to show consistent results in treating yeast with many of the dietary changes and other commonly-promoted treatments, although many have attempted to prove this.

We know that there is some correlation of Candida overgrowth with several other illnesses. For instance, higher numbers of Candida and a higher incidence of food allergies often coexist. But we don't really know whether this coexistence is causative or merely a correlation. Does Candida overgrowth cause food allergies, or do the allergies create an environment conducive to the Candida overgrowth, or both?

Even among those who adamantly believe in the Candida epidemic as the cause of many or most health problems among the human population, there is much disagreement as to the proper treatment.

A certain food will be listed on the "never eat" list of one "expert" while the same food is on the "beneficial" list of another. Foods like lemons or potatoes are often encouraged by one Candida proponent while forbidden by another. Some recommend taking garlic every day, while others caution against eating it daily for fear of creating allergies.

Some protocols recommend taking nystatin or another antifungal antibiotic for months or years at a time, while others warn against creating a tolerance for it if it's taken for more than 10 days or so at a time.

In some cases antifungal treatment or a special diet is clearly indicated. It has been helpful for many. Since it has very little risk, it's certainly worth consideration when nothing else is working. Especially if a person has recurrent, stubborn fungal infections, it makes sense to look at Candida as a possible cause.

But there is little proof that any one of these protocols alone really solves the problem in the long term for the majority of people with symptoms of "candida overgrowth".

Many people stay on the treatments for years or months at a time with little or no long-term improvement. This is not necessarily due to "cheating" on the diet, even though the diet is so restrictive and nearly impossible to follow that any failure of the treatment can almost always be blamed on such cheating. I know people personally (including family members) who were diagnosed with Candida overgrowth and stuck faithfully to the prescribed treatments with no real positive results.

Individual body systems are so unique, and a food or other variable that may be helpful for one person can be harmful for another.

Especially for a person whose diet is already strictly limited by food allergies, intolerances or other factors, cutting out all fruits and sugars along with most starches and grains could be counterproductive and may not always be necessary. The expense, frustration and side effects of a medication may not be worthwhile if the issue can be dealt with another way.

In many cases, dealing with the underlying issues and getting the body and digestive system healthier in general may allow any Candida overgrowth to resolve on its own.

Yes, Candida is an opportunistic organism that will grow wherever there's a weak spot. But when so many people seem to not be getting better and there are so many differing and disagreeing opinions about how to treat Candida, I think there may be something else going on.

It seems likely that, even if Candida is present, Candida may not be the actual cause of some or all of the symptoms for many people.

For instance, a lot of my "candida" symptoms went away when I cut coconut, dairy products and eggs out of my diet. I'm allergic to those foods. My daughter's symptoms are also drastically better when we avoid her allergens.

I know of a lot of corn-allergic people who had a collection of symptoms that fit the Candida profile (and in some cases they believed were caused by Candida), but went away when they finally removed corn and all its hidden derivatives (a monumental task in itself) from their diets. Undiagnosed food allergies can weaken the immune system just as something like Candida can.

Corn is a really hard one to pinpoint, because it is so pervasive in our food supply (even showing up unlabeled on fresh fruits, vegetables and meats) and because the symptoms can be so atypical for allergy. There is some speculation of a cellular-level autoimmune reaction similar to celiac disease that corn may cause in some people.

Another issue that I think complicates things for my child is that she is severely allergic to molds, and possibly to yeasts also. So, for that reason, she will probably never be able to freely eat lage quantities of foods that contain or easily feed yeasts and molds (unless she grows out of the allergy). I think any Candida in her body may affect her more drastically in smaller amounts because of that also.

We also found out that a lot of her supposed "candida symptoms" were being caused by severe reflux and aspiration (a swallowing problem which was causing fluids to go down the tube to her lungs instead of to her throat), and by anemia (iron deficinecy).

Finally, a recent stool test showed that she does not have the ability to process certain sugars.

Some people's bodies do not make the enzymes necessary to digest one or more sugars, whether it be galactose, glucose or fructose. Those people will get symptoms when they ingest that sugar. In some cases, this can easily be solved by supplementing the necessary enzyme.

There are people who are truly allergic to certain types of sugars. I am allergic to maple trees, and maple syrup gives me problems. Quite a few people are allergic to sugar cane because it is a grass closely related to several other grains (notably corn). People who are allergic to sugar cane can often eat beet sugar without problems. Other people are allergic to beets, and so might react to beet sugar while being fine with cane sugar.

All of these things can cause symptoms and a pattern of flare-ups that seem completely consistent with disease caused by Candida. They may even flare up when foods said to feed yeast are consumed, but really have a totally different cause and treatment. In a situation where Candida treatments are not very effective, it would be wise to look for other causes of the symptoms.

For us, dealing with these other causes and underlying issues has brought our health to the point where the difficulty, side effects and limitations of the candida treatment doesn't seem to have enough potential gain in health to be worth it. If we're feeling fine eating moderate amounts fruit, starchy vegetables and whole grains, why should we stop eating them? Especially when fruit and other more complex carbohydrates contain so many valuable nutrients and benefits to health.

Of course, anybody's health is going to improve by cutting out refined sugars and excessive carbohydrates, cultivating healthy intestinal flora, eating more vegetables, drinking more water and living a healthier lifestyle--whether they have an illness caused by Candida or not.

In my situation and and Baby E's, my instincts are telling me to focus on the underlying issues and on general good health rather than hyperfocusing on the Candida itself.

I do want to make clear that I'm not trying to dismiss Candida as an element of illness. For many people it is a very real and serious part of their health problems.

But Candida is an opportunistic organism that has to have a vulnerable environment in order to take over. Even if Candida is actually causing problems, just treating the Candida may not adequately resolve the issue.

If a person doesn't deal with whatever root issues left them vulnerable to Candida in the first place, most likely no amount of nystatin is going to make them truly well in the long term. As soon as they go off the treatments it is likely to just grow again, since it is a normal organism always present in the human system.

PK,
I'm going to bring up one point that you didn't mention, which is to get a comprehensive GI panel done to check for candida if you suspect it all. I agree self-diagnosis is never a good idea, but neither is discounting something that could very well be the root of multiple problems. In my case, 3 years worth of doctor visits yielded me nothing but more misery. I asked my doctor about candida numerous times and was told it wasn't a credible reason for my illnesses. I was just "getting older."
I researched my symptoms, and suspected candida, but had no idea how to get tested for it at that time. It took me almost a year to find the correct type of testing. I followed candida diets and took antifungals in the meantime. Those two small steps were the best I could do for myself at that time. I am eternally grateful to the people on health forums who took the time to share their knowledge with me. If it wasn't for them I don't know where I woudl be. They allowed me to make the jump from bedridden mom who was planning her own funeral to functional mom who could care for her family again. Before that my doctor tested me and could find NOTHING wrong with me at all. Told me I was depressed, implied I was lazy, a hypochondriac, just needed to exercise, etc. I finally had the GI panel done and, as I already knew, yeast was the source of my 20 plus medical problems, from night sweats to chronic yeast and bacterial vaginosis to hand tremors to depression and bladder frequency... all of which I had been given prescriptions for. The mercury, antibiotics and processed diet Americans in general flood themselves with are proven causes of yeast growth. While yeast may not be the largest part of the puzzle for everyone, I encourage other readers of this blog not to discount yeast as quackery. If you suspect, even slightly, that your symptoms could be related to candida, get yourself tested (Diagnos Tech) and let the results speak for themselves. It could make a dramatic difference in the quality of your life.

Thanks for this great post, PK! My sister has a diagnosed allergy to shellfish (crustaceans only: shrimp, lobster, crab...) and has been seeing a naturopath for "yeast" issues. I'm wondering if her yeast issues might not actually be an undiagnosed allergy instead. She does well when she's not eating sugar, and poorly when she does. Perhaps it's the sugar rather than the candida? I'm going to forward your post to her and let her decide.

Tara, I wasn't trying to completely discount Candida as an element of illness.

But I do strongly believe that Candida is an opportunistic organism and that if a person doesn't deal with whatever root issues left them vulnerable to Candida, most likely no amount of nystatin is going to make them truly well in the long term. As soon as they go off the treatments it is likely to just grow again, as it's not something you're ever going to get rid of completely.

I am not really all that familiar with the various tests. My naturopath just had me do a urine test.

I'm glad the diet and antifungals have been helpful for you. You obviously had one of the fairly sure-fire symptoms of a fungal problem that I mentioned earlier--recurrent, persistent yeast infections.

Candida treatments were very helpful for me in the past, although I'm not really sure whether it was ultimately that or the other life changes and treatments I was also undergoing at the time--or a combination of all those things--that really made me well. Like you, I was expecting to spend the rest of my life in a wheelchair at the time.

However, my sister also had the positive urine test and did the same treatments I did, and was helped little if at all.

At this time Baby E and I seem to be benefitting from treating other causes while not seeing any real difference with the antifungal treatments.

Since we had already been on a very healthy diet free of bleached, enriched foods and refined carbohydrates for months, the only effect I saw from the Nystatin and restricting our diet further was frustration and Baby E's allergic reaction to the nystatin.

Although I'm sure we both have or had had higher than average concentrations of Candida, I think it likely that in our case this was the result rather than the cause of other issues, or that our healthier diet had already largely allowed our bodies to deal with the issue on their own.

Since we cannot have legumes, eggs, or many of the other foods foundational to a truly strict Candida diet, it just doesn't make sense for us to cut out all fruits, starchy vegetables and grains without a really compelling reason.

I just don't think we fit into the catch-all category of "illness caused by candida" at this point.

Now, if Baby E gets significantly worse after being off the nystatin I may change my mind. But right now she seems much healthier while not taking a medication that causes allergic reactions for her and wasn't really doing much if anything for her in the first place.

Liz, sugar (and especially refined sugars like white cane sugar) can suppress the immune system and cause a lot of health issues all on its own, even in the absence of Candida or allergy.

Most people would be much healthier if they cut out all refined sugars and limit other sugars such as honey or maple syrup to a few teaspoons per day. Whole fruit is a much better source of sugars, as it also contains a lot of vitamins and fiber, but anything in excess isn't good for us.

Our bodies aren't designed to handle large quantities of artifically concentrated glucose--especially when it's stripped of all the minerals and enzymes inherent in the original food that would help our bodies to process it.

The book Sugar Blues is an interesting read and makes a lot of good points even though I don't agree with everything in it.

I think with Candida it's often a chicken and egg type question. In my case I believe the candida came first and then the other issues. Some people find that a round of antibiotics followed by a silver filling replacement triggers infection. They could be in perfect health previous to those two events.
Candida is such a complex issue. There are more than 20 species of yeast and each can manifest with different symptoms depending on an individual's body terrain. The whole thing becomes more complex when the number of toxins (70+) that a single yeast cell produces is considered. This extra load taxes the liver and from there other body systems are strained causing a chain reaction of symptoms throughout the body.
A comprehensive stool/saliva test will tell which species and what level of growth an individual has. Whether it's an allergen or eyesight, or anything in between, testing with a competent professional is key. From what I have seen and experienced yeast is not a one-cure-fits-all situation, nor is it a quick fix.
It's also important for women to note that you do not need to have a yeast infection to have yeast overgrowth. Yeast infections open the door to multiple female infections, such as BV. The BV symptoms usually win out over the yeast and women can have both without knowing it. Even doctors, due to insurance specs, will not test for both but, just the infection they think is dominant (BV). Women with BV should insist that their doctor test for both or they will only go around in circles.
With the strict diet you and Baby E have been on, you are already essentially starving the yeast. If Baby E's allergy flare-ups are negating any Nystatin benefit than I agree that it is pointless.
You've gotten your candida to a level that is livable. That's wonderful, your health puzzle has just had another piece completed!
I would feel sad though, thinking that someone with their own health issues might miss that opportunity since the symptoms for both things are often the same.
The GI Panel through Diagnosis Tech or Genova Diagnostics will test for candida, parasites, bacterial overgrowth, a set number of common food allergens and siaga levels.
Best of luck to you and the family PK, although it sounds as if you are all on the road to a better 2007.

Tara, those sound like some good tests. Do they have to be prescribed by a doctor?

I'm sure the information you have shared will be helpful to some.

Part of my reason for writing this post was to explain why I don't think Candida needs to be my focus for Baby E and me personally at this time. Also, there is a TON of information online (and I run into it all the time IRL too) suggesting that Candida is practically the root of all illness.

I'm not saying that Candida isn't sometimes a cause of illness, and I'm not discouraging people from looking into whether that may be a factor for them.

What I AM saying is that it's dangerous to assume the issue is Candida (even if a Candida overgrowth test comes back positive) without considering other possibilities also. I also thought it valuable to point out that other issues can cause the same or very similar symptoms while not being caused by Candida.

For instance, here's a page comparing Candida symptoms with Celiac disease . . . there's really a lot of overlap, and a person could have both issues going on at once. In that kind of situation, just treating the Candida without also treating the Celiac disease would not be effective.

It's possible that treating the celiac disease could allow the Candida to clear up on its own (although it could also require antifungal treatment), because it will bring healing and balance to the digestive tract. But treating just the Candida while continuing to eat traces of gluten wouldn't make for a significant or permanent improvement in the person's health.

My main point is that if treating the Candida isn't helping, then you might want to look for other causes. Also that, in general (not just with Candida) it's a good idea to have some tests and panels run by a doctor before self-diagnosing or treating yourself for a disease.

Would you agree with that?

PK,
Of course your point makes total sense. I'm not trying to be some kind of Candida Nazi, just wanting people to realize that there are good reliable tests available, not just do-it-yourself questionnaires and the like. I think Candida is a very valid reason for many illnesses and often goes hand-in-hand with things like diabetes, chronic fatigue, depression, celiac's etc. I also there is a lot of misdiagnosis because Candida is not taken seriously and mainstream doctors do not run the correct tests for it. But that's a whole different post.
I would never advocate leaving any body imbalance unaddressed. All parts are equally important to the whole.

Whoops! Forgot to say that the tests I mentioned to need to be ordered from a physician. If you can't find one in your area who uses them, the Diagnos Tech website has a link to find a provider in your area.

It's important to consider the source before buying the argument that mainstream doctors discount candida.
If a "lab" gives kickbacks to "doctors," it's not a good idea to trust them. If you've paid lab fees directly to your "doctor," you've been had.

A few years ago, Andrew Weil's newsletter had an article about questionable lab reports with disclaimers on them.

Even worse than the kickbacks are the fabricated conditions that are just money making scams. There's a good reason why "intestinal permeability" hasn't been embraced by the legitimate medical community.
The science isn't behind the tests.

There's a "special place" for those who rob senior citizens of their life savings.

Those disclaimers on the lab reports allow them to say almost anything they want.

Watch out for a stool test report that says you have abnormally high levels of proteus mirabilus and/or klebsiella oxytosa in the digestive tract. There are no such conditions. There are plenty of traditional & holistic doctors who would confirm this fact. You just have to find the honest ones.

The American College of Pathologists explained that loopholes in the law allow these practices.

The prescribing of huge doses of toxic substances such as wormwood is also a despicable practice.

To clarify, Dr. Weil's article just mentioned questionable lab tests. Dr. Weil isn't involved in those unpleasant practices explained in my previous posts.
