A vaginal yeast infection is a common condition caused by the overgrowth of fungus in the vagina, leading to itching, soreness, and unusual discharge. Medically referred to as vaginal candidiasis, vulvovaginal candidiasis, or candida vaginitis, it is the second most frequent vaginal infection after bacterial infections. Each year, around 1.4 million people seek medical care for vaginal yeast infections.

While these infections can be uncomfortable, they are typically easy to diagnose and treat. Most symptoms improve within a few days of starting antifungal treatment, although recurring infections may require longer therapy. About 5–9% of individuals experience four or more infections annually.

Symptoms of Vaginal Yeast Infection

Common symptoms of a vaginal yeast infection include:

• Itching and soreness around the vulva or vagina
• Vaginal discharge, which may appear white and lumpy like cottage cheese or sometimes more watery
• Pain during urination or sexual intercourse in some cases

While most symptoms are mild, more severe cases can involve redness, swelling, and cracking of the vaginal skin.

Because symptoms can overlap with bacterial vaginosis (BV), certain sexually transmitted infections (STIs), or dermatitis, it’s important to consult a healthcare provider for an accurate diagnosis.

Causes and Risk Factors

Vaginal yeast infections are caused by an overgrowth of Candida albicans, a fungus naturally found on the skin and in the body. Normally, Candida exists in small amounts in the vagina, mouth, and intestinal tract without causing issues. An infection occurs when this balance is disrupted, allowing the fungus to multiply.

Factors that increase the risk include:

• Pregnancy
• Diabetes or poorly controlled blood sugar
• Antibiotics, hormonal birth control, or certain chemotherapy drugs
• Stress and lack of sleep
• Scented tampons or douches
• Contraceptive devices like diaphragms, IUDs, or vaginal sponges
• Weakened immune system due to conditions like HIV, chemotherapy, corticosteroids, or post-transplant medications

Diagnosing Vaginal Yeast Infection

Diagnosis begins with a review of symptoms and a physical examination of the vulva and vagina. Your healthcare provider may take a sample of vaginal discharge to confirm the presence of yeast.

For recurrent or severe infections, additional tests may be needed to identify underlying causes. It is crucial to get a professional diagnosis before starting treatment, as symptoms of yeast infections can mimic other conditions. Misdiagnosis can worsen symptoms and lead to unnecessary expenses.

Treatment for Vaginal Yeast Infection

Treatment typically involves antifungal medications that stop the growth of Candida. Options include:

• Topical treatments: Creams or suppositories inserted directly into the vagina
• Oral antifungals: Pills such as fluconazole (Azocan, Diflucan, Canesten Thrush Oral Capsules) are used for severe, recurrent, or menstruating cases.

Treatment duration varies: one, three, or six days for most cases. For recurring infections, your provider may recommend a longer course, such as multiple doses of fluconazole over several days, followed by weekly doses for up to six months.

Most individuals feel relief within a few days, but consult a healthcare provider if symptoms persist after treatment.

Prevention Tips

If you are prone to recurrent vaginal yeast infections, identifying triggers can help prevent future episodes. Common preventive strategies include:

• Only take antibiotics when prescribed, and inform your provider if you frequently develop yeast infections
• Avoid douching and scented products, including soaps, sprays, and tampons
• Do not wear wet swimsuits for extended periods
• Maintain stable blood sugar levels
• Wear breathable, cotton clothing instead of tight or synthetic materials

Even if the exact cause is unknown, these steps can reduce your risk of infection.

Related Conditions

Frequent vaginal yeast infections may indicate an underlying health issue. For example:

• Diabetes: Poorly controlled blood sugar or certain medications like SGLT2 inhibitors can increase infection risk
• HIV: Weakened immunity makes it harder for the body to prevent infections

Work with your healthcare provider to manage these conditions to lower the risk of recurrent infections.

Key Takeaways

Vaginal yeast infections are common, uncomfortable, but generally easy to treat. Most individuals recover within a few days, and additional treatment can help if symptoms persist. Being aware of triggers and preventive strategies can significantly reduce the likelihood of future infections.
