White Vaginal Discharge: Causes and Treatment

White discharge (leukorrhea) can be entirely normal or a sign of infection. Treatment depends entirely on the underlying cause, so the color alone isn't diagnostic - texture, smell, and associated symptoms (itching, burning, pain) matter more.

1. Physiological (normal) discharge - no treatment needed

A thin, milky-white, odorless discharge that varies with the menstrual cycle (more around ovulation, before periods, in pregnancy, or with hormonal contraceptives) is normal cervical/vaginal secretion. No treatment is required beyond routine hygiene. Douching should be avoided - it disrupts normal vaginal flora and doesn't help prevent or treat vaginitis - Textbook of Family Medicine, 9e.

2. Vulvovaginal candidiasis (yeast infection) - most common cause of "curdy white" discharge

  • Presentation: thick, white, "cottage cheese"-like discharge, intense vulvar itching, burning, vaginal soreness, normal vaginal pH (<4.5).
  • Cause: Candida albicans (85-90% of cases); antibiotic use, pregnancy, diabetes, and immunosuppression predispose to it - Berek & Novak's Gynecology, p.811.
  • Treatment:
    • Uncomplicated: Fluconazole 150 mg orally, single dose, OR clotrimazole vaginal pessary/cream (e.g., 500 mg single dose or a shorter multi-day course).
    • Complicated/recurrent disease (severe symptoms, non-albicans species, immunocompromised, or ≥4 episodes/year): longer courses (e.g., fluconazole 150 mg every 72 hours for 3 doses) and sometimes maintenance therapy - Berek & Novak's Gynecology.

3. Bacterial vaginosis (BV)

  • Presentation: thin, gray-white, adherent discharge with a fishy odor (worse after intercourse), pH >4.5, "clue cells" on wet mount.
  • Cause: overgrowth of anaerobes (Gardnerella vaginalis and others) replacing normal lactobacilli - not a classic STI but linked to sexual activity.
  • Treatment: Metronidazole 500 mg orally twice daily for 7 days, or metronidazole vaginal gel, or oral tinidazole/secnidazole single-dose regimens - Park's Textbook of Preventive and Social Medicine.

4. Trichomoniasis

  • Presentation: yellow-green or white, frothy, malodorous discharge, vulvar erythema, dysuria; sexually transmitted.
  • Treatment: Metronidazole or tinidazole 2 g orally single dose, or metronidazole 500 mg twice daily for 7 days if single-dose fails. Sexual partner must be treated simultaneously, and intercourse avoided until both are asymptomatic. Alcohol should be avoided with these drugs - Textbook of Family Medicine, 9e, p.622.

5. Cervicitis / other STIs (chlamydia, gonorrhea)

Can also present with whitish-mucopurulent discharge, often with intermenstrual bleeding or pelvic pain.
  • Treatment: Cefixime 400 mg orally single dose plus azithromycin 1 g orally single dose (or per current local/CDC STI guidelines) - Park's Textbook of Preventive and Social Medicine.

6. Atrophic vaginitis (postmenopausal)

Thin, sometimes whitish discharge with dryness and pain from low estrogen; treated with topical vaginal estrogen.

General approach

Because syndromic treatment (treating for multiple causes at once without lab confirmation) is common in resource-limited settings, but proper diagnosis (vaginal pH, KOH prep, wet mount, or NAAT testing) gives targeted, more effective treatment and avoids unnecessary antibiotic/antifungal use.
See a doctor if discharge is foul-smelling, colored (yellow/green/gray), accompanied by itching, burning, pelvic pain, fever, or bleeding, or if you are pregnant - self-diagnosis by symptoms alone is unreliable, and a clinician can confirm the cause with a quick exam and microscopy.
A recent systematic review confirms bacterial vaginosis, candidiasis, and STIs (chlamydia/trichomoniasis) remain the leading causes of abnormal vaginal discharge globally, reinforcing that etiology-directed treatment (not empiric guessing) gives the best outcomes (Michalow et al., 2024, PMID: 38768094).
