Yeast infections. You say the phrase and it immediately conjures up images of itching, burning, and lots of wiggling around in your seat. It almost makes you automatically clench up your vaginal muscles, as if that could prevent unwanted intruders from disrupting your sexual health, right?
Go ahead and unclench. Yeast infections, though not exactly pleasant, aren't the end of the world, says Lisa Masterson, MD, a practicing OB-GYN and former co-host of "The Doctors."
"Most women get super anxious about them, wondering how they got it, what this means for their long-term health, and how to treat it," she says. "But it's a super-treatable infection that isn't going to haunt you forever."
So even if you think you know everything there is to know about yeast infections, read on. The surprising statistics — and myth-busters— might surprise you.
1. Yeast infections are ridiculously common... and yet most women don't know what to do about them.
Three out of four women are diagnosed with a yeast infection at some point in their life, Mayo Clinic reports. But according to a June 2015 survey by Monistat, the makers of a treatment cream for yeast infections, 53 percent of women don't have a clue about how to deal with them, and 67 percent of women don't know how to cure them. Which explains why Monistat launched the It's Time for TMI campaign — with yeast infections being so common, there's no reason for you to not understand what's happening with your vagina.
2. It isn't anything like an STD.
According to that same survey cited above, 81 percent of patients that come in to treat a yeast infection fear that it was sexually transmitted through their partners or that having sex led to the infection. Point blank, it wasn't. Not even close. A yeast infection, in fact, is simply a pH imbalance inside of the vagina that leads to a buildup of yeast, and it's often caused by your hormones going out of whack, Dr. Masterson explains.
"It can be caused by a myriad of things — hormonal contraceptives like the Pill, stress, a weakened immune system because you're tired or not sleeping well, and environmental conditions, like staying in your sweaty clothes or wet bathing suit," she says.
3. It's also different from a bacterial infection.
Even more common than STD concerns is the at-home misdiagnosis of a yeast infection, or the assumption that it's like — and therefore treated the same way as — a bacterial infection. "They both fall under the heading of vaginitis, or inflammation of the vagina, and bacterial vaginosis can sometimes be confused with yeast infections because the symptoms are similar," Dr. Masterson says. "But bacteria shifts the vaginal pH in a different direction and requires an antibiotic to clear it up, while a yeast infection needs an anti-fungal cream."
4. You'll be able to recognize the symptoms at home.
There isn't a critical need to rush to your gyno if you think you might have a yeast infection. Tests like Monistat's Vaginal Health Test are sold over the counter, and they check your vaginal pH to help you distinguish whether something's a yeast or bacterial infection. So if you have the classic symptoms — fishy odor, abnormal discharge, and/or itching or burning — use the strip test to check your vagina's acidity level. If it comes back normal after 10 seconds, it's likely a yeast infection. If not, it could be a bacterial infection that requires antibiotics and a chat with your OB-GYN, like bacterial vaginosis or trichomoniasis. "Either way, taking the test helps clear the infection sooner because you're not wasting any time on a treatment that won't work for the specific type of infection that you have," Dr. Masterson says. Just be sure to consult your doc about the problem, too.
5. They're not chronic.
To the 67 percent of women who think yeast infections can never be cured, we say take a deep sigh of relief: Just because you've got one doesn't mean you're doomed for the rest of your life. "Each case is individual, and you can cure each one," Dr. Masterson says. "It does not increase your risk of getting more down the road. So you just take the proper treatment, wait a full week — which is how long it takes to cure a yeast infection, even if you only need to treat symptoms for one day — and then it's gone for good."
6. You'll probably get more after having babies.
Sorry, moms, but Dr. Masterson says you're more likely to get a yeast infection after you've had children. In fact, many women don't experience their first one until they're either pregnant or have just had children because of the hormonal shift that occurs. "The hormone prolactin, which lets down milk and helps with breastfeeding, encourages other hormones to stick around, and it can cause the pH imbalance," she explains. "It can even stop your periods and make your body feel like it's almost in a menopausal state; menopausal women have an increased risk of yeast infections, as well."
7. Just because you don't have symptoms doesn't mean you don't have an infection.
Unfortunately (or fortunately, depending on how you look at it), not every woman experiences the usual itching, burning, or weird discharge symptoms right away. In fact, if you're not super sensitive, you might not realize you have one at all. "Some women will come in for their regular Pap smear and I'll notice a colonization of yeast, and it's the first time they're even thinking about it," Dr. Masterson says. "It depends on the sensitivity of the person. For one woman who's really sensitive, a small colonization can cause a lot of itching and burning. For another, it takes a larger buildup of yeast to cause those symptoms." That said, it's not a big deal if you don't treat it right away, she explains. So long as you're not experiencing symptoms that are causing you to be uncomfortable, it's OK if it's treated later.
8. Too much sugar can up your risk.
Wait, your sweet tooth might be causing issues with your — vagina? Actually, yes. Yeast thrives on sugar, so eating too much of it might increase your chance of developing the obnoxious infection, says Laurie Birkholz, MD, a doctor specializing in women's health in Holland, Michigan. If it seems like you're always getting another yeast infection, you might want to monitor your diet and pass on the sugary stuff.
9. Yes, your partner can catch it from you.
Not only can sex hurt (because vaginal tissue is already sensitive and irritated) when you have a yeast infection, but you can also pass on your symptoms to your partner, Dr. Birkholz says. Although, as previously mentioned, it's not considered an STD, having unprotected sex while you're dealing with an infection can lead to an itchy rash on your guy's penis. Uh, ouch. That, plus the fact that getting it on might delay the amount of time it takes you to heal (sex can cause the medical cream you're using to pull a disappearing act), might mean you want to wait until you've been treating your infection for a few days before engaging in anything hot and heavy.
10. Your gym clothes might be to blame.
If your post-workout routine involves collapsing on the couch — because, hello, you just killed that spin class, so you can be lazy forever, right? — you might want to think again. "Lounging around in sweaty clothing creates an environment that's conducive to yeast growth," Dr. Birkholz says. "It's best to change out of your workout gear and put on dry clothes as soon as you're done at the gym." That's an easy way to prevent trouble.
