10 Things Every Woman Should Know About Yeast Infections

Yeast infections are incredibly common—three out of four women will experience at least one in their lifetime. Caused by an overgrowth of a fungus called Candida, these infections can be uncomfortable but are usually treatable. Still, there’s a lot of misinformation out there. Let’s clear things up with 10 facts every woman should know.

1. They’re Not Sexually Transmitted Infections (STIs)

While yeast infections can be triggered by sexual activity, they aren’t classified as STIs. You can get one even if you’re not sexually active.

2. Symptoms Can Be Confused with Other Conditions

Itching, burning, and thick white discharge are common signs—but these symptoms can also occur in other vaginal infections like bacterial vaginosis or STIs. Always get a proper diagnosis.

3. Antibiotics Can Trigger Them

Antibiotics kill harmful bacteria—but they also wipe out the good bacteria that keep yeast in check. That’s why many women get yeast infections after a round of antibiotics.

4. They Can Recur

Some women get recurrent yeast infections, defined as four or more in a year. This could be due to hormone imbalances, diabetes, or even lifestyle factors.

5. Tight or Non-Breathable Clothing Can Make It Worse

Wearing tight jeans or synthetic underwear can trap moisture, making it easier for yeast to grow. Opt for cotton underwear and avoid staying in wet clothing (like swimsuits or workout gear) for too long.

6. Sugar Feeds Yeast

Yeast thrives on sugar. A high-sugar diet may increase your risk of infection—especially if you have diabetes or blood sugar issues.

7. You Can Get a Yeast Infection from Stress

Chronic stress can weaken the immune system, allowing yeast to grow unchecked. Managing stress can support your body’s natural defenses.

8. Over-the-Counter Treatments Work—But Not Always

Many yeast infections can be treated with OTC antifungal creams or suppositories. But if symptoms persist or worsen, you might need a prescription or further testing.

9. Probiotics May Help Prevent Them

Probiotics (especially those with Lactobacillus) help restore the balance of good bacteria in your gut and vagina, which may reduce your chances of future infections.

10. Don’t Self-Diagnose Too Quickly

Treating a condition that you assume is a yeast infection—but isn’t—can delay proper care. If it’s your first time experiencing symptoms, see a doctor before buying any medications.

Bottom Line:
Yeast infections are common, but with the right knowledge and care, they don’t have to be a recurring problem. Stay informed, listen to your body, and don’t hesitate to consult a healthcare provider when in doubt.
