There are several factors to consider; see below to understand more. Vaginal yeast infections happen when Candida overgrows after antibiotics, hormonal shifts, high blood sugar, moisture and friction, irritants, or immune changes, leading to intense itching, burning, redness, and thick white discharge.
Next steps include keeping the area dry, avoiding scented products and douching, considering an OTC antifungal if this matches a past confirmed infection, and seeking care if symptoms are severe, recurrent, atypical, occur in pregnancy, do not improve, or include fever, pelvic pain, foul odor, or poorly controlled diabetes, since other conditions can mimic yeast and may need different testing and treatment outlined below.
If you're still itching, burning, or feeling uncomfortable "down there," you're not alone. A vaginal yeast infection—also called candidal vulvovaginitis—is one of the most common vaginal conditions. Most women will experience at least one in their lifetime, and many will have more than one.
The good news: yeast infections are usually treatable and not dangerous.
The not-so-good news: they can be extremely uncomfortable and sometimes confusing.
Let's break down why vaginal yeast infections happen, what symptoms to look for, and what you should do next.
A vaginal yeast infection happens when a fungus called Candida—most often Candida albicans—overgrows in the vagina.
Candida normally lives in small amounts on your skin and inside your body, including the vagina. In healthy conditions, "good" bacteria (especially lactobacilli) keep yeast levels balanced. But when that balance shifts, yeast can multiply quickly and cause symptoms.
This is not a sexually transmitted infection (STI), although sexual activity can sometimes trigger symptoms.
Yeast overgrowth usually happens when something disrupts your body's natural balance. Common triggers include:
Antibiotics kill harmful bacteria—but they also wipe out helpful bacteria that control yeast growth. Without those protective bacteria, yeast can multiply.
Changes in estrogen levels can increase your risk. This includes:
Higher estrogen levels can make the vaginal environment more favorable for yeast growth.
High blood sugar feeds yeast. If blood sugar levels are not well controlled, yeast infections may happen more often or be harder to treat.
If your immune system is under stress—due to illness, medications (like steroids), or certain medical conditions—your body may struggle to keep yeast levels in check.
Yeast thrives in warm, moist environments. Risk can increase with:
Products that disrupt vaginal pH or irritate tissue can increase risk:
The vagina is self-cleaning. Adding products can upset its natural balance.
Symptoms can range from mild to intense. The most common include:
Not everyone has discharge. For some, itching and irritation are the main signs.
It's important to know that other conditions can cause similar symptoms, including:
If symptoms are new, severe, unusual, or keep coming back, it's worth double-checking the diagnosis.
To help identify whether your symptoms align with a yeast infection or another condition, you can use a free AI-powered symptom checker for Candidal Vulvovaginitis (Yeast Infection) that analyzes your specific symptoms and provides personalized guidance on next steps.
Treatment depends on severity and frequency.
Over-the-counter antifungal treatments are often effective. These include:
Typical treatment lasts 1–7 days depending on the product.
Most people feel relief within a few days, though full symptom resolution can take up to a week.
If you have:
You may need:
Sometimes, a different Candida species is involved, and that can change the treatment plan.
Recurrent vaginal yeast infections (four or more per year) happen in a small percentage of women. Possible reasons include:
In some cases, no clear cause is found.
If infections keep returning, it's important to speak with a doctor. Recurrent symptoms may need lab testing and a structured treatment plan.
If you suspect a vaginal yeast infection, here are practical next steps:
Scratching can break the skin and make irritation worse.
If you've had a confirmed yeast infection before and symptoms feel identical, over-the-counter antifungal medication may help.
If you're unsure, consider a symptom check or speak with a healthcare professional before starting treatment.
While most vaginal yeast infections are not dangerous, you should speak to a doctor promptly if you have:
These signs could indicate a more serious condition or a different diagnosis.
If anything feels severe, unusual, or worsening, don't wait.
You can't always prevent a vaginal yeast infection—but you can reduce your risk:
Probiotics are often discussed, but evidence on their effectiveness in preventing vaginal yeast infections is still mixed. If you're considering supplements, discuss them with your doctor.
A vaginal yeast infection is uncomfortable—but usually manageable and treatable. It happens when the natural balance of bacteria and yeast in your vagina shifts, allowing yeast to grow out of control.
Common causes include antibiotics, hormonal changes, diabetes, and moisture. Symptoms often include itching, burning, redness, and thick white discharge.
If you're unsure whether your symptoms point to a vaginal yeast infection, take a few minutes to complete a free symptom checker for Candidal Vulvovaginitis (Yeast Infection) that can help clarify your symptoms and recommend appropriate next steps.
Most importantly, listen to your body. If symptoms are severe, unusual, recurring, or accompanied by pain or fever, speak to a doctor. While yeast infections are rarely life-threatening, some vaginal symptoms can signal more serious conditions that require medical attention.
Relief is possible—and you don't have to guess your way through it.
