What is a Yeast Infection?
A yeast infection is a common fungal overgrowth, typically caused by Candida albicans. It often affects the vaginal area, but can also occur in the mouth, skin folds, or under the nails. It is not considered a sexually transmitted infection, but sexual activity can trigger symptoms in some people.
Quick Facts

What Causes a Yeast Infection?
- Overgrowth of Candida yeast, most commonly Candida albicans
- Disruption of normal vaginal or skin flora, which normally keeps yeast in balance
- Recent antibiotic use, which can reduce protective bacteria
- Hormonal changes, such as pregnancy or hormonal contraceptive use
- High blood sugar levels, including in people with diabetes
- Weakened immune response, due to illness, stress, or certain medications
- Warm, moist environments, which promote yeast growth
- Irritation or changes in the local environment, such as scented products or tight clothing
Risk Factors
- Age
- Pregnancy
- Chronic conditions (e.g., diabetes)
- Medications
- Lifestyle or occupational factors
Treatment Options for a Yeast Infection
Self-Care / OTC Options (when appropriate)
- Over-the-counter antifungal creams or suppositories (e.g., miconazole, clotrimazole) for uncomplicated symptoms
- Supportive care: keep the area clean/dry, avoid tight/irritating clothing, avoid scented products that can worsen irritation
Prescription Treatment
- Prescription antifungal medication may be recommended based on symptoms, history, pregnancy status, or recurrence
- Some cases may require a longer course or different regimen, depending on the clinical situation
Recurrent or Complicated Symptoms
Medical evaluation is especially important if:
- Symptoms return frequently (recurrent episodes)
- Symptoms don’t improve after OTC treatment
- You are pregnant, immunocompromised, or have diabetes
- There is pelvic pain, fever, or unusual discharge (signals possible alternate diagnoses)
In these cases, a clinician may consider testing to confirm the cause and rule out other conditions (e.g., bacterial vaginosis or STIs).
