Vaginal yeast infections are one of the most common vaginal infections affecting women. Although they are usually not serious, they can cause intense itching, irritation, and discomfort. Most yeast infections are easily treated, but recurrent infections may require further medical evaluation to identify an underlying cause.
Health experts estimate that most women will experience at least one vaginal yeast infection during their lifetime.
What Is a Vaginal Yeast Infection?
A vaginal yeast infection, also known as vaginal candidiasis, is a fungal infection caused by an overgrowth of Candida, most commonly Candida albicans.
Candida normally lives in small amounts in the vagina without causing problems. However, when the natural balance of bacteria and yeast is disrupted, the fungus can multiply rapidly and cause symptoms.
What Causes a Yeast Infection?
Several factors can increase the risk of developing a vaginal yeast infection, including:
- Taking antibiotics.
- Pregnancy.
- Uncontrolled diabetes.
- A weakened immune system.
- High oestrogen levels, such as during pregnancy or hormone therapy.
- Wearing tight or damp clothing for long periods.
Yeast infections are not usually classified as sexually transmitted infections (STIs), although they can occasionally occur after sexual activity.
Common Symptoms
Symptoms may range from mild to severe and often include:
- Intense vaginal itching.
- Burning sensation around the vagina.
- Redness and swelling of the vulva.
- Thick, white vaginal discharge that resembles cottage cheese.
- Pain during sexual intercourse.
- Burning during urination.
- Small cracks or soreness of the skin around the vagina.
Some women may experience only a few of these symptoms.
Who Is at Risk?
You may be more likely to develop a yeast infection if you:
- Have diabetes, especially if blood sugar is poorly controlled.
- Are pregnant.
- Frequently take antibiotics.
- Have a weakened immune system.
- Have had previous yeast infections.
Some women experience recurrent yeast infections several times a year.
How Is It Diagnosed?
A healthcare provider may diagnose a yeast infection by:
- Asking about your symptoms and medical history.
- Performing a pelvic examination.
- Taking a sample of vaginal discharge for laboratory testing if the diagnosis is uncertain or infections keep returning.
This helps distinguish a yeast infection from bacterial vaginosis, sexually transmitted infections, and other vaginal conditions.
Treatment
Most vaginal yeast infections can be treated successfully.
Treatment may include:
Antifungal Medications
These are available as vaginal creams, pessaries (tablets inserted into the vagina), or oral medications prescribed by a healthcare professional.
Managing Underlying Conditions
Women with diabetes should aim for good blood sugar control, while those with recurrent infections may require further medical evaluation.
It is important to complete the full course of treatment, even if symptoms improve quickly.
Can Yeast Infections Be Prevented?
You may reduce your risk by:
- Keeping the genital area clean and dry.
- Wearing breathable cotton underwear.
- Avoiding tight-fitting clothing for long periods.
- Avoiding unnecessary antibiotic use.
- Controlling blood sugar if you have diabetes.
- Avoiding scented soaps, vaginal sprays, and douches that may disrupt the natural balance of the vagina.
These measures help maintain a healthy vaginal environment.
When Should You See a Doctor?
Seek medical advice if you:
- Are experiencing vaginal symptoms for the first time.
- Have severe pain, fever, or pelvic pain.
- Are pregnant and think you have a yeast infection.
- Have recurrent infections (four or more in one year).
- Do not improve after treatment.
- Notice foul-smelling discharge or unusual bleeding.
These symptoms may indicate another condition requiring different treatment.
The Bottom Line
Vaginal yeast infections are common and usually respond well to antifungal treatment. Symptoms such as intense itching, burning, and thick white discharge should not be ignored, especially if they are severe or keep returning. Early diagnosis ensures appropriate treatment and helps rule out other vaginal infections with similar symptoms.
