A vaginal yeast infection, also known as vaginal candidiasis, is a common fungal infection that causes discomfort for many women. Characterized by irritation, itching, and discharge, it affects the vagina and vulva. It’s important to understand that while yeast infections can be related to sexual activity, they are not classified as sexually transmitted infections (STIs). Many individuals assigned female at birth will experience at least one yeast infection in their lifetime, and some may have them repeatedly. So, how exactly do you get a yeast infection? Let’s explore the causes, symptoms, and ways to prevent this common condition.
Unpacking the Causes: How Yeast Infections Develop
The vagina naturally hosts a balanced environment of yeast, including Candida, and bacteria. Beneficial bacteria, primarily lactobacillus, play a crucial role in maintaining this balance by preventing the overgrowth of yeast. However, certain factors can disrupt this delicate equilibrium, allowing Candida or other types of fungus to multiply excessively and penetrate deeper into vaginal tissues, leading to a yeast infection.
Several factors can contribute to this imbalance and increase the likelihood of developing a yeast infection:
- Antibiotic Use: Antibiotics, especially broad-spectrum ones, are designed to combat bacterial infections. Unfortunately, they can also eliminate beneficial bacteria in the vagina, including lactobacillus. This reduction in good bacteria allows yeast to flourish unchecked.
- Hormonal Fluctuations: Changes in hormone levels, particularly an increase in estrogen, can create a more favorable environment for yeast growth. Conditions like pregnancy, the use of birth control pills, and hormone therapy can elevate estrogen levels, increasing susceptibility to yeast infections.
- Unmanaged Diabetes: High blood sugar levels, often associated with poorly managed diabetes, can also promote yeast infections. Yeast thrives on sugar, and elevated glucose levels in the vagina can fuel their overgrowth.
- Weakened Immune System: A compromised immune system, whether due to medical conditions like HIV or certain medications like corticosteroids, makes it harder for the body to control yeast populations. This can lead to an increased risk of yeast infections.
While Candida albicans is the most frequent culprit behind vaginal yeast infections, other types of Candida fungus can also cause these infections, sometimes proving more challenging to treat.
Recognizing the Symptoms: What to Look For
Yeast infection symptoms can vary in intensity from mild to moderate. Being aware of these signs can help in seeking timely and appropriate care:
- Itching and Irritation: Persistent itching and irritation in the vagina and vulva are hallmark symptoms.
- Burning Sensation: A burning feeling, particularly during sexual intercourse or urination, is common.
- Redness and Swelling: The vulva may appear red and swollen. Note that redness might be less obvious on darker skin tones.
- Vaginal Pain and Soreness: General pain and tenderness in the vaginal area can occur.
- Abnormal Vaginal Discharge: The discharge associated with a yeast infection is typically thick, white, and often described as resembling cottage cheese. It usually has little to no odor.

In some cases, yeast infections can become complicated. You might be experiencing a complicated yeast infection if:
- Your symptoms are severe, with intense redness, swelling, and itching that leads to breaks in the skin, cracks, or sores in the vagina.
- You experience four or more yeast infections within a year, indicating recurrent infections.
- The infection is caused by a less common type of fungus, potentially requiring different treatment approaches.
- You are pregnant, as pregnancy can sometimes complicate yeast infections.
- You have diabetes that is not well-managed, making infections harder to control.
- Your immune system is weakened due to medications or conditions like HIV, making you more vulnerable to severe or persistent infections.
Are You at Risk? Identifying Risk Factors
Several factors can elevate your risk of developing a yeast infection. Understanding these risk factors can empower you to take preventive measures:
- Antibiotic Use: As mentioned earlier, antibiotics are a significant risk factor due to their impact on vaginal flora.
- Elevated Estrogen Levels: Conditions and medications that increase estrogen levels, such as pregnancy, birth control pills, and hormone therapy, increase the risk.
- Uncontrolled Diabetes: Poorly managed blood sugar creates a favorable environment for yeast overgrowth.
- Compromised Immunity: A weakened immune system makes you more susceptible to infections, including yeast infections.
Prevention is Key: How to Reduce Your Risk
While yeast infections are common, there are practical steps you can take to minimize your risk and maintain vaginal health:
- Choose Cotton Underwear: Opt for underwear with a cotton crotch. Cotton is breathable and helps to keep the vaginal area dry.
- Avoid Tight Clothing: Refrain from wearing excessively tight pantyhose, underwear, or jeans, as they can trap moisture and heat, creating a conducive environment for yeast.
- Skip Douching: Douching disrupts the natural balance of bacteria in the vagina, potentially increasing the risk of infections. The vagina is self-cleaning and douching is generally unnecessary and can be harmful.
- Use Unscented Products: Avoid scented feminine products in the vaginal area, including bubble bath, soaps, menstrual pads, and tampons. Fragrances can irritate sensitive tissues and disrupt the natural balance.
- Limit Hot Tubs and Hot Baths: Prolonged exposure to hot tubs and very hot baths can create a warm, moist environment that encourages yeast growth.
- Use Antibiotics Judiciously: Only use antibiotics when necessary and as prescribed by a healthcare professional. Avoid using them for viral infections like colds.
- Change Out of Wet Clothes Promptly: Don’t stay in wet clothing, such as swimsuits or workout clothes, for extended periods. Change into dry clothes as soon as possible to reduce moisture.

When to See a Doctor
It’s crucial to consult a healthcare professional in the following situations:
- First-Time Symptoms: If you are experiencing symptoms of a yeast infection for the first time, it’s essential to get a proper diagnosis to confirm it is indeed a yeast infection and not another condition.
- Uncertainty About Diagnosis: If you are unsure whether your symptoms are due to a yeast infection, seek medical advice for accurate diagnosis and appropriate treatment.
- Persistent Symptoms After OTC Treatment: If your symptoms do not improve or resolve after using over-the-counter antifungal creams or suppositories, consult a doctor.
- Additional Symptoms: If you experience other concerning symptoms alongside those typical of a yeast infection, such as fever, pelvic pain, or foul-smelling discharge, seek medical attention promptly.
In Conclusion
Understanding how you get a yeast infection involves recognizing the delicate balance within the vagina and the factors that can disrupt it. By being aware of the causes, symptoms, risk factors, and preventive measures, you can take proactive steps to maintain vaginal health and minimize your risk of yeast infections. If you suspect you have a yeast infection or have concerns about your vaginal health, don’t hesitate to consult a healthcare professional for guidance and treatment.
