Understanding Yeast Infections
A yeast infection, medically called vulvovaginal candidiasis, is caused by an overgrowth of Candida species—most often Candida albicans. Around 75 % of people with vaginas will experience at least one episode in their lifetime. The fungus lives naturally on skin and mucous membranes, but changes in the vaginal environment can allow it to multiply.
Common Symptoms
- Intense itching or burning in the vulvar area
- Thick, white, odor‑free discharge that resembles cottage cheese
- Redness, swelling, or soreness of the vulva
- Pain during intercourse or urination
If you notice these signs, a proper diagnosis is important because other conditions—such as bacterial vaginosis or sexually transmitted infections—can mimic them.
When to See a Healthcare Provider
- First‑time symptoms – to confirm the diagnosis.
- Recurrent infections (four or more per year).
- Symptoms that do not improve after over‑the‑counter treatment.
- Pregnancy, diabetes, or a weakened immune system.
A clinician can perform a quick pelvic exam and, if needed, a microscopic examination of vaginal discharge.
Evidence‑Based Treatment Options
Topical Antifungals
Over‑the‑counter creams, ointments, or suppositories containing clotrimazole, miconazole, or tioconazole are first‑line therapy. Typical courses last 1–7 days, depending on the product strength. Follow the package instructions exactly even if symptoms disappear early.
Oral Antifungal
A single 150 mg dose of fluconazole is an alternative for those who prefer a pill. It is prescription‑only in many regions and may interact with certain medications, so discuss it with your provider.
Combination Therapy
For complicated or recurrent cases, a longer topical course (10–14 days) followed by a weekly oral dose for six months may be recommended. This regimen has shown lower recurrence rates in clinical studies.
Lifestyle Measures That Support Recovery
- Wear breathable cotton underwear and avoid tight‑fitting synthetic garments.
- Change out of wet clothing (swimsuits, workout gear) promptly.
- Limit unnecessary antibiotic use—antibiotics can disrupt the normal vaginal flora.
- Maintain good glycemic control if you have diabetes; high blood sugar fuels yeast growth.
- Avoid douching, scented soaps, and feminine sprays that alter vaginal pH.
Preventive Strategies
While not every infection can be prevented, the following habits reduce risk:
