Vulvovaginitis: Types, Symptoms and Treatment for Indian Women

• Vulvovaginitis is an umbrella term, not one disease — the common causes are bacterial vaginosis (BV), vulvovaginal candidiasis (yeast), trichomoniasis, irritant or allergic reactions, and atrophic vaginitis after menopause.
• Symptoms overlap heavily, so self-treating from a single symptom often fails. Discharge character and vaginal pH are the two most useful clues a clinician uses to tell them apart.
• BV (thin grey discharge, fishy smell, pH above 4.5) and yeast (thick white discharge, intense itching, normal pH) are the two most common — and they need completely different medicines.
• Douching and harsh intimate washes make most cases worse, not better. The vagina is self-cleaning; you only ever wash the external vulva.
• Fever, severe pelvic pain, abnormal bleeding, symptoms in pregnancy, sores or ulcers, or four-plus episodes a year are red flags that need prompt medical review rather than another tube of OTC cream.

Vulvovaginitis is the medical term for inflammation of the vulva (the external genitals) and the vagina (the internal canal) at the same time. It is best understood as an umbrella term rather than a single disease. The inflammation can be infectious (a bacterial, yeast or parasitic overgrowth), non-infectious (an irritant or allergic reaction to a product), or hormone-related (the thinning of vaginal tissue after menopause).

What makes vulvovaginitis confusing is that the symptoms overlap heavily across causes. Itching, burning, abnormal discharge, redness and painful sex can all appear with BV, yeast, trichomoniasis or an irritant reaction. That is exactly why a single-symptom self-diagnosis from an internet search or a relative's advice is unreliable, and why using the wrong treatment — a yeast cream when the real problem is BV, say — usually does not help and can disturb the vaginal balance further.

The good news is that vulvovaginitis is generally diagnosable in one OPD visit, treatable with inexpensive evidence-based medicines available across India, and preventable in most recurrent cases with a few specific changes. Vaginal symptoms are a common medical complaint with well-established care pathways — not something to feel ashamed of or to silently endure. If you are unsure whether your discharge is even abnormal, our guide on normal versus abnormal vaginal discharge is a calmer place to start than panic-Googling a symptom.

Bacterial vaginosis (BV) is the single most common cause of abnormal discharge in reproductive-age women. It is not a classic infection but a shift in the vaginal microbiome — the protective lactobacilli that normally dominate are crowded out by anaerobic bacteria such as Gardnerella vaginalis, the pH rises above 4.5, and a thin discharge with a fishy odour develops. Vulvovaginal candidiasis (a yeast infection) is the second most common cause, driven by overgrowth of Candida albicans, often after antibiotics, during pregnancy, in poorly controlled diabetes, or with a weakened immune system.

Trichomoniasis is a sexually transmitted parasitic infection caused by Trichomonas vaginalis. It is less common but important because the partner must be treated too. Irritant or allergic vulvovaginitis is a non-infectious inflammation triggered by scented soaps, perfumed sanitary pads, douches, intimate washes, tight synthetic underwear or detergent residue — and it is often missed because both women and clinicians tend to assume an infection. Atrophic vaginitis affects women after menopause; it is driven by falling oestrogen thinning the vaginal tissue, and shows up as dryness, burning and painful sex rather than infection.

Less common causes include aerobic vaginitis (overgrowth of aerobic bacteria such as E. coli or group B streptococcus), foreign-body vaginitis (a retained tampon or condom fragment), and desquamative inflammatory vaginitis. In young, prepubertal girls, vulvovaginitis is usually irritant or hygiene-related rather than infectious.

The core symptoms of vulvovaginitis are itching, burning, abnormal discharge, redness, swelling, pain during sex (dyspareunia) and stinging when urine touches inflamed vulval skin. Not every woman has every symptom, and the pattern varies by cause. Itching dominates in yeast and irritant vulvovaginitis, often badly enough to disturb sleep. Burning is more typical of BV, trichomoniasis and atrophic vaginitis. Abnormal discharge is the cardinal sign of BV and trichomoniasis but is often minimal in irritant or atrophic cases.

Discharge character is the single most useful clue for narrowing down the cause:

BV has a distinct fingerprint when the symptoms are read carefully. The discharge is thin and watery rather than thick, grey-white, and clings to the vaginal walls in a film rather than coming out in clumps. The defining feature is the strong fishy or amine odour, which classically worsens after unprotected sex (semen is alkaline and releases the volatile amines) and during menstruation (menstrual blood is also alkaline). Itching is usually mild or absent — if itching is your dominant symptom, yeast is more likely than BV.

The vaginal pH in BV is above 4.5 (a normal vaginal pH is 3.8 to 4.5), and this is one of the simplest, cheapest tests available in Indian OPDs — a pH paper strip touched to the vaginal wall costs roughly Rs 50–100 and gives an answer in seconds. Your doctor may also do a whiff test (a drop of potassium hydroxide on a discharge sample releases the fishy smell) and look for clue cells on wet-mount microscopy to confirm the diagnosis using the Amsel criteria. That fishy or sour smell is a frequent reason women come in; we cover it on its own in vaginal odour: normal versus fishy.

BV is not classically a sexually transmitted infection, but it is more common in women with new or multiple partners, and recurrence is common — around a third of women treated for BV have another episode within three months. If yours keeps returning, our deep-dive on recurrent bacterial vaginosis covers the microbiome, biofilms and longer-term strategies.

A yeast infection has its own recognisable pattern. The discharge is thick, white and clumpy with a cottage-cheese texture, and has little or no odour — that absence of smell is itself useful, because a strong odour points away from yeast and towards BV or trichomoniasis. Intense itching is the dominant symptom, often severe enough to disturb sleep or leave scratch marks. Redness and swelling of the vulva and vaginal opening are common, sometimes with small satellite lesions or fissures.

The vaginal pH in yeast stays normal at below 4.5 (unlike BV, where it is raised), so the same quick pH test that helps confirm BV also helps rule it out. Wet-mount microscopy or, rarely, a fungal culture shows budding yeast and pseudohyphae. Yeast is most often triggered by a recent course of antibiotics (which kill protective lactobacilli), pregnancy (hormones favour yeast), poorly controlled diabetes (high blood sugar feeds yeast), and immune suppression of any kind.

Recurrent yeast — four or more episodes a year — deserves a proper workup, because it can signal undiagnosed type 2 diabetes or a resistant non-albicans species (such as Candida glabrata) that does not respond to standard fluconazole. A blood-sugar check is reasonable in any woman with repeated yeast infections; for a fuller plan see our guide on recurrent yeast infections.

Most vulvovaginitis is uncomfortable but not dangerous, and an OPD appointment within a few days is fine for typical symptoms. Some features, though, should prompt same-day or urgent contact rather than waiting:

Diagnosis is usually straightforward and inexpensive, and the great majority of cases can be settled in a single visit without elaborate testing. The consultation begins with a focused history — onset and pattern of symptoms, discharge character, recent antibiotics, sexual history, contraception, menopausal status, product use and prior episodes — followed by a speculum examination to look at the vulva, vagina and cervix and to rule out a foreign body or cervical problem. If a pelvic exam makes you anxious, our walk-through on what to expect before a pelvic exam explains every step and your right to consent.

A vaginal pH measurement with pH paper (a cheap strip, roughly Rs 50–100 per visit) is the single most useful bedside test: a pH above 4.5 points to BV or trichomoniasis, while a normal pH below 4.5 points to yeast or an irritant cause. The Amsel criteria for BV require three of four features — thin grey-white discharge, pH above 4.5, a positive whiff test, and clue cells on microscopy. Wet-mount microscopy is widely available in Indian OPDs and identifies clue cells (BV), yeast and pseudohyphae (candida), or motile trichomonads (trichomoniasis).

Culture is rarely needed for typical cases but helps in recurrent yeast (to identify resistant species) or refractory cases. STI screening for chlamydia, gonorrhoea, HIV and syphilis is appropriate in anyone diagnosed with Trichomoniasis (Trich) in Indian Women: Symptoms, Tests, Cure or with risk factors — NACO runs free, confidential testing, as covered in our guide to STI screening for Indian women. A urine routine and culture rule out a co-existing UTI when burning urination is prominent.

Because the causes are so different, the treatments are too — which is why an accurate diagnosis matters before you reach for any medicine. The figures below are typical Indian retail prices and may vary by city and brand.

Bacterial vaginosis (BV) is treated with metronidazole 500 mg orally twice a day for seven days (sold as Flagyl, Metrogyl or Aristogyl, around Rs 50–100 for a full course) — the gold-standard regimen per FOGSI and international guidelines. Alternatives include metronidazole vaginal gel once daily for five days, or clindamycin vaginal cream at bedtime for seven days for women who cannot tolerate oral metronidazole. Avoid alcohol during oral metronidazole and for 48 hours afterwards, because of a disulfiram-like reaction (nausea, vomiting, flushing).

Vulvovaginal candidiasis (yeast) is treated with fluconazole 150 mg orally as a single dose (Forcan, Funzole, Syscan or Zocon, around Rs 50–150 per tablet), which clears uncomplicated cases in two to three days. Alternatives include a clotrimazole vaginal cream or pessary (Candid, Canesten or Candid-V, around Rs 50–150) at bedtime for six to seven nights, or miconazole. Recurrent yeast (four-plus episodes a year) needs a longer suppressive course of weekly fluconazole for up to six months under medical guidance — see how to clear and prevent candida.

Trichomoniasis is treated with metronidazole 2 g orally as a single dose, with the partner treated at the same time — this is essential, as an untreated partner causes immediate reinfection. Irritant or allergic vulvovaginitis is treated by stopping the offending product (the scented wash, douche or perfumed pad) plus, for severe inflammation, a short course of low-potency topical steroid such as 1% hydrocortisone. Atrophic vaginitis is treated with topical vaginal oestrogen (estriol cream or pessaries) and regular moisturisers or lubricants, with steady improvement over four to six weeks; our guide on vaginal dryness and on atrophic vaginitis after menopause covers this in depth.

Recurrence is common — roughly a third of treated BV cases return within three months, and 5–10% of women get recurrent yeast — so a few specific habits make a measurable difference:

Most uncomplicated vulvovaginitis is sorted in one visit, but certain situations need specialist evaluation rather than repeated OTC self-treatment. Recurrent episodes (four or more a year) need a workup for an underlying cause — undiagnosed diabetes, a resistant species, persistent partner reinfection in trichomoniasis, or immune suppression — and a tailored long-term plan rather than the same short course each time.

Pregnancy with any vaginal symptoms deserves early review, because untreated BV and trichomoniasis in pregnancy are linked to preterm labour and low birth weight, and treatment uses specific safe regimens (oral metronidazole is considered safe beyond the first trimester; clotrimazole cream is preferred over fluconazole in the first trimester). Women past menopause with new symptoms — discharge, bleeding or pain — need careful evaluation, because the differential includes atrophic vaginitis but also cervical or uterine pathology that must be ruled out.

A failed response to standard treatment after seven to ten days, severe vulval pain that lingers after the infection clears, visible vulval skin changes (white patches, thickening or ulcers), and symptoms after a new partner all warrant review. If you find these conversations hard to start, our piece on talking to a doctor about vaginal pain can help. Telemedicine through eSanjeevani, Practo or 1mg is a confidential option for an initial discussion, and ASHA workers can provide confidential referral pathways for women who find it difficult to attend a clinic.

Myth: Douching cleans the vagina and prevents infection. Fact: It does the opposite — it washes out protective lactobacilli, raises vaginal pH, and increases the risk of BV, yeast and PID. The vagina is self-cleaning and needs no internal washing. Indian gynaecologists and international guidelines consistently advise against douching of any kind, including with water, salt water or vinegar.

Myth: A yeast infection means I have an STI. Fact: A yeast infection is not classed as an STI — yeast is part of the normal vaginal and gut flora and overgrows when the balance shifts, most often after antibiotics, in pregnancy or with diabetes. You can get yeast without ever being sexually active. Trichomoniasis is the only common vaginal infection that is sexually transmitted.

Myth: Tight jeans or synthetic underwear cause infections. Fact: Tight or synthetic clothing does not cause infection by itself, but it creates a warm, moist environment that favours overgrowth and can contribute to recurrence in women already prone to it. Cotton and breathable clothing are sensible, but the primary causes are microbiome disturbance, hormonal change and irritant exposure.

Myth: Eating or applying yogurt cures a yeast infection. Fact: There is no good evidence that dietary or topical yogurt cures an established yeast infection, and applying it vaginally can introduce other organisms and worsen irritation. The evidence-based treatment is oral fluconazole or clotrimazole cream. Curd, lassi and buttermilk are fine as part of general health, but are not a substitute for proven medicine during an active infection.
