The Yeast Beast!

Hello darlings! My friends often call me up to ask about yeast infections, and they often have crazy ideas about them. I’m going to try to settle some of the punk myths and point y’all toward some true facts about your friend and mine, Candida.

To start off, there are four main bodily locations of yeast infections: mouth, the “vagina”, feet, blood. These are respectively called: oral thrush, ‘innie’ genital (sometimes called “vaginal”) yeast infections, athlete’s foot, and systemic yeast. There are also yeast infections of the skin in general, but that’s a different topic I’m not covering here. A lot of punks erroneously confuse one yeast infection for another!

These are all overgrowths of yeasts in the Candida family. It is normal and healthy to have some Candida yeasts growing in and on the body all the time. Remember when giant jellyfish were attacking Japan and Florida? ( Yeast infections are a little bit like that. It’s normal for the ocean to have some jellyfish in it, but when some ecologic disturbance happens, or sometime just because, jellyfish bloom out of control and other fish are crowded out. That’s sort of what happens with yeast.

[EDIT: This may actually be the normal cycle of jellyfish and not aberrant. I still like the metaphor.]

It’s healthy and normal and all that jazz to have some yeast in and on the body all the time. It normally lives peaceably with its neighbors in small quantities. Every now and then, something upsets the balance and yeast blooms out of control and crowds everything else out. That’s when you have a problem.

Myth 1: Genital yeast can be cured by diet changes.

Genital yeast lives in the interior portion of AFAB1 genitals or of surgically constructed vaginas. The interior portions of the genitals, where yeast is most commonly a problem, are not connected to the intestines2. There is a wall of tissue and muscle between the intestines and the inside genitals. It’s part of what makes anal sex different from genital sex. It’s what keeps poop from coming out of the genitals. Yeast cannot walk through this wall. Yeast eats sugars, so many people claim that not eating sugar will cure a genital yeast infection. When you eat sugar, it goes through the mouth, to the stomach, through the intestines, and out as poop. In this journey, it does not normally pass through the genitals. Therefore, putting sugar in your mouth is not the same as putting sugar in the genitals. Unless you have severe untreated diabetes, the body’s blood sugar is well-regulated. Try this simple experiment if you do not believe me: eat a bunch of sugar, rinse your mouth with water, wait a while, lick your skin. Lick in several places. Does it taste like sugar? Spoiler alert; it won’t. So, it might be generally healthy to avoid sugar, but avoiding it will not “starve out” a yeast infection. That said, if you have a yeast infection, you may want to avoid putting sugar directly on or in your genitals (whipped cream, jelly, etc) until the infection is gone. If you have yeast in your mouth (called “thrush”), it makes sense to avoid putting sugar in your mouth.

Note, it is possible to have a yeast infection in both the intestines and the genitals at the same time, just like you can have say, a cold and also have pink eye, but it doesn’t mean they are the same thing or necessarily cause one another.

EDIT: I have gotten a lot of questions asking if the rise in blood sugar after eating gives sugar to the yeast. I have finally found a good answer! Here is the pathway: When a non-diabetic person eats, their blood sugar does rise. However, it will not rise above 180, even if they mainline glucose. This is because the body produces a hormone called ‘insulin’ in response to a rise in blood sugar. This insulin is like a ‘key’ that lets the sugar into the ‘locked’ cells of the body. Once the sugars are inside the body’s cells they are no longer accessible to yeasts. It is true that a small amount sugars may remain for a time in the fluid between cells, but it is not enough sugar to make a difference to the yeast. So, yes, there is a tiny amount of sugar that might theoretically become accessible to yeast after you eat, but even if it did, it is not enough to really feed the yeast, and definitely not enough to make a difference one way or another to the infection.

Take-Home message: Do Not attempt to cure a (non-oral) yeast infection through diet changes. It will not work and may cause other problems.


 Myth 2: Genital yeast infections are caused by eating bread, drinking beer, or otherwise ingesting yeasts.

The type of yeast that causes most yeast infections is Candida albicans. The less common infection-causing yeasts are other members of the family Candida. The yeasts used in beer and bread making are usually in the Saccharomycetaceae family. They are not the same. If you are MOSTLY eating bread and drinking alcohol, such as drunk punks who live on dumpstered bagels do, you may end up with yeast simply because this diet completely trashes the immune system along with the rest of the body. You may also end up with scurvy, which is way less romantic to experience than it might sound. The yeast that makes the infection is part of the normal flora of the body.


Myth 3: My genitals itch, I probably have systemic yeast (yeast in my blood).

Yeast infections can end up in the bloodstream of people with severely compromised immune systems, such as people with HIV/AIDS or people on chemotherapy. This is a serious, life-threatening condition called candidemia. If you have a severely compromised immune system, you hopefully do not need me to tell you it’s absolutely imperative that you do not seek out health opinions from blogs. Do what you know you should and see a professional health care provider. If you do not have the kind of severely compromised immune system that occurs with chemotherapy, HIV/AIDS, etc, and you aren’t in an intensive care unit in a hospital, you pretty much don’t have this issue. Keep in mind that my opinions are absolutely not medical advice, and I’m no authority on these things, and neither are most other punks! If you think you have this kind of condition, absolutely see a doctor or a physician’s assistant right now! Otherwise, calm down and try not to look up medical symptoms on the internet and then assume the worst.


Myth 4: Tea-tree oil is a gentle way to treat a genital yeast infection.

Tea tree oil applied to genital mucosa, especially when the tissue is irritated by yeast, hurts like the dickens. It burns and hurts and stings and it’s oil, so it’s hard to get it out of there once it goes in. If you’re into that kind of thing, more power to you. There are other treatments, both alternative and conventional that don’t hurt like crap. I’m not sure what you think “gentle” means, but to me, burning pain and gentle aren’t the same thing. I’d suggest other treatments instead. Tea tree oil is fine for yeast on the feet, also called “athlete’s foot”, where it might sting some, but the skin’s less sensitive and it’s easier to wash off if you can’t stand it.


Myth 5: Probiotics such as those in yogurt can cure a yeast infection.

Probiotics do a great job at preventing yeast infections, but they do not do much to cure them on their own. If you are on antibiotics, or otherwise feel the need to actively prevent an infection, by all means, use probiotics. If you already have an infection, you’re going to need to treat the infection you have before you can start preventing the next one. Keep in mind that the probiotics that live in AFAB and other innie genitals are NOT the same ones that live in the intestine, nor the ones in yogurt. Also, please see the above discussion of how the genitals are not connected to the intestine. The idea of eating yogurt is that somehow the bacteria will survive the entire intestinal tract and then “walk” from the anus to the genital opening, this is really unlikely and also you should generally be avoiding bacterial transfer in that direction. i.e., you should wipe front to back. Some recent evidence suggests the probiotics in yogurt aren’t the ones that are present in healthy innie genitals anyway. The best way to get probiotics into the genitals is to get suppositories made especially for that area.


Myth 6: I’ve been treating a yeast infection for months, they just take a long time to go away.

Yeast infections generally clear up in a matter of days. That is to say, less than one week. If you have been treating a yeast infection for longer than a week, you either: have a different kind of infection (such as a bacterial infection), or your treatment isn’t working and you need to try something else. I’d say, if you’ve been trying an herbal remedy, it’s time to try a conventional one. If you’ve been trying a conventional one, it’s time to see a professional for an accurate diagnosis. Don’t suffer for weeks or months! There is no need to do that. Anyone who tells you otherwise is in my opinion misguided and isn’t looking out for your interests. There is plenty of suffering in life already, and suffering from yeast is not some kind of punishment for sinfulness or whatever. For real, I think a lot of punks have a quasi-religious mindset that they deserve what’s coming to them. Point is, if your treatment isn’t working in a matter of days, it isn’t going to up and start working later.


Myth 7: My genitals are itchy. It’s yeast.

Maybe, but it could also be bacterial vaginosis or an STD. The symptoms are incredibly similar. The best way to tell is to swab the area, but the swab on a microscope slide, treat THE SLIDE (not the body!!!) with a strong base to lyse (pop) the human cells, and look at the slide under the microscope. If you have equipment and training to do that, neat! Why are you readin’ this? If you don’t (or if you do, honestly), the very best way to get diagnosed is to see a health professional that can actually look at the beasts and identify them. Want to know what’s rustling around your tent? Is it a possum or a raccoon? You can lie awake and guess all night, or you can get a flashlight and look at the darn thing. If you want to treat it as yeast first, be my guest, but if it doesn’t work, see a professional, you may need antibiotics or some such.


Myth 8: Yeast infections are not STIs (sexually transmitted infections).

While yeast infections are not ‘truly’ STIs, they can be transmitted by sexual contact. Be sure to wash any toys, clothing items, or other stuff that comes in contact with your yeast infected area before sharing the items and also before using it again on yourself! You can theoretically re-infect yourself later. People do not commonly get yeast infections on their hands, but you may want to avoid having genital to genital contact while you have a yeast infection. (You should definitely avoid genital-genital contact until you get a professional diagnosis, because what if it turns out you have the clap and you told your sex partner/s that it was yeast?) You should also avoid mouth-to-genital contact, cases of thrush can be spread to genitals, and genital yeast can be spread to the mouth as thrush. Healthy adults do not commonly get thrush, so it’s fairly low risk but still possible to transmit yeast from genitals to mouths. If you have had sexual contact, you may all want to be treated for yeast infections before you have sex (with whatever parts have the yeast) again. If you have regular sex with someone, and you can’t figure out where you keep getting yeast infections from and you’ve been tested for diabetes and other stuff, you might want to consider the possibility that they have yeast and are giving it to you over and over! Also, some people just get yeast infections more commonly than others because everyone’s different! Sorry!


I hope that cleared some things up. If you have any questions or if you’ve heard any punk myths about yeast I haven’t included here, I’d love to hear about it!

1AFAB means “assigned female at birth”. I will be using the terms “AFAB genital yeast”, “innie genitals”, or “genital yeast” to refer to what some might call “vaginal yeast” because many people with this anatomic structure do not call it a vagina. Some people do call it a vagina, and that’s great too. Please keep in mind that there are yeasts of the outie-style genitals, but I will not be discussing those yeasts in this post!

2Sometimes they are. This is called a “vaginal fistula”, and believe me, you’d know it if you had one. If you do, you already know you should clearly consult a professional about your situation.

  1. a very interesting blog, and as someone who is very moderate perhaps I miss the point, but I’m fairly certain that in all yeast infections, while limiting sugar intake will not cure the infection, it will help. I agree that your skin wouldn’t taste sweeter after sugar, but you do get hyper, we know this from our youngest years. The body tries real hard to maintain a blood-sugar level, but it still gets a spike, and it can have its lows.. I only mention cause my mother who’s a natural-remedy sort (selling oils and herbs) suggests that when you’re craving sugar, it can be in part the natural flora yeast you talked about getting a little more than it should, and my own science experience with my microbiology degree. Interesting none-the-less

    • Thank you for your comment! I’m sorry I haven’t been on in a long while. There seems to be a healthy interest in where sugar goes in the body and what it does and doesn’t do when it gets there. There may not be a consensus on this issue, but I’m back in the game, have greater access to medical journals and the like than ever before, and I’m looking into it again.
      I find the idea that the yeast in the gut could perhaps influence our thoughts/desires fascinating. You might enjoy the book “The Second Brain” about gastroneurology. This is a newly emerging field and I see many possibilities there, but for my purposes, I’ll be sticking to more tried-and-true approaches than innovative ones. This is because I lack the medical experience necessary to offer opinions on newer subjects, not because of a prejudice against the un-proven. One day I hope to be able to offer reasonable evidence-based advice from my own experience, but I’ll have to have more experience first.
