Vaginitis: Causes, Symptoms, Types, and What Actually Helps
Vaginitis is one of the most common reasons women visit a GP or gynaecologist — and one of the most commonly misunderstood. It’s not a single condition with a single fix. It’s an umbrella term for vaginal inflammation, and the cause behind it matters enormously when it comes to treatment.
This article covers everything you need to know: what vaginitis actually is, how to recognise it, why it keeps coming back for so many women, and what a genuinely supportive approach looks like.
What Is Vaginitis?
Vaginitis means inflammation of the vaginal tissues. That inflammation can be triggered by an infection, a hormonal shift, a chemical irritant, or an imbalance in the microbial communities that normally keep the vagina healthy.
It is not the same as a yeast infection, though yeast overgrowth is one cause. It is not the same as bacterial vaginosis (BV), though BV is another cause. Understanding what’s driving the inflammation is what determines whether a treatment will actually work — or why it might not.
Symptoms of Vaginitis
The symptoms may vary depending on the cause, but the most common include:
- Itching or irritation inside the vagina or around the vulva
- Burning, particularly during urination or after intimacy
- Unusual discharge — changes in colour, texture, volume, or smell
- Redness or swelling of the vaginal tissues
- Discomfort or pain during sex
- Dryness, particularly in women experiencing hormonal changes
Symptoms can appear suddenly or build gradually. They can also be intermittent, which is part of why vaginitis is so frustrating — it can seem to clear up, then return without obvious reason.
One important note: the same symptoms can point to very different causes. Thick white discharge with intense itching suggests yeast overgrowth. A fishy odour with thin, greyish discharge is more associated with bacterial vaginosis. Dryness and irritation without discharge may signal hormonal changes. Getting the cause right before treating is essential.
Types of Vaginitis
1. Yeast Vaginitis (Candida)
Caused by overgrowth of Candida species — most often Candida albicans — yeast vaginitis is among the most well-known types. Symptoms typically include intense itching, a thick cottage cheese-like discharge, and a burning sensation, particularly during urination.
Triggers include antibiotic use (which disrupts protective bacteria), high sugar intake, hormonal fluctuations, pregnancy, immune suppression, and chronic stress. Many women experience it once and never again; others deal with it repeatedly.
The recurring pattern is key: recurrent yeast infections (defined as four or more per year) are often a sign that the underlying environment hasn’t been addressed — only the individual flare-up has been treated.

2. Bacterial Vaginosis (BV)
BV is the most common cause of vaginitis in women of reproductive age, though it’s frequently misdiagnosed or left untreated because some women have no symptoms at all.
It occurs when the balance of bacteria in the vagina shifts — specifically, when Lactobacillus species decline and other bacteria (like Gardnerella or Prevotella) overgrow. This shift raises vaginal pH from its naturally acidic state, making the environment less protective.
Typical signs include a fishy odour (often more noticeable after sex), thin discharge that may appear grey or white, and mild irritation. BV is not a sexually transmitted infection, but sexual activity — particularly with new or multiple partners — can influence vaginal pH and microbiome balance.
BV responds to antibiotics in the short term, but recurrence rates are high. This is because antibiotics treat the overgrowth without necessarily restoring the Lactobacillus populations that keep BV from returning.
3. Hormonal (Atrophic) Vaginitis
When oestrogen levels drop — during perimenopause, menopause, postpartum recovery, or while breastfeeding — vaginal tissues can thin, dry out, and become more vulnerable to irritation and infection.
This is called atrophic vaginitis or, more recently, genitourinary syndrome of menopause (GSM). Symptoms include persistent dryness, soreness, pain during sex, and increased susceptibility to infections. There is usually no abnormal discharge.
Because this type isn’t caused by a pathogen, antifungals and antibiotics won’t help. Hormonal or non-hormonal moisturisers, lubricants, and in some cases local oestrogen therapy are more appropriate approaches.
4. Irritant or Contact Vaginitis
Not all vaginitis has an infectious or hormonal cause. Chemical irritants are a surprisingly common culprit — and one that’s easy to overlook.
Soaps, bubble baths, scented pads or tampons, douches, fabric softeners, synthetic underwear, and even some lubricants can disrupt the vaginal environment and cause inflammation. This type of vaginitis tends to resolve once the irritant is removed, but continued exposure can make symptoms persistent.
5. Mixed Vaginitis
Some women have more than one type occurring simultaneously — for example, a yeast infection alongside BV, or BV alongside hormonal dryness. This complicates both diagnosis and treatment, as addressing only one cause may leave symptoms partially unresolved. Mixed vaginitis is more common than many people realise, and it’s worth raising with a healthcare provider if treatments repeatedly seem to only partially work.
Why Does Vaginitis Keep Coming Back?
Recurrent vaginitis is one of the most common — and most demoralising — women’s health experiences. If you’ve been treated and treated again and still find yourself back at square one, you’re not imagining it, and it’s not because you’re doing something wrong.
Recurrence happens for several interconnected reasons:
Treating the symptom, not the cause. Antifungals clear a yeast overgrowth but don’t address what allowed the yeast to overgrow in the first place. Antibiotics reduce BV bacteria but can simultaneously wipe out the Lactobacillus species the vagina needs to stay balanced — making a future episode more likely, not less.
Biofilm. Some species of Candida and Gardnerella can form biofilms — protective structures that make them significantly more resistant to treatment. Standard courses of medication may not fully penetrate a biofilm, leaving a reservoir of organisms that can re-establish once treatment stops.
Microbiome depletion. A vaginal environment rich in Lactobacillus species — particularly L. crispatus — is naturally resistant to yeast overgrowth and bacterial imbalance. When those populations are chronically low, the vagina is more vulnerable to repeated episodes.
Ongoing triggers. If the factors that contributed to the first episode (diet, antibiotic use, stress, irritants, hormonal changes) remain unchanged, recurrence is almost inevitable.
Misdiagnosis. If vaginitis keeps coming back despite treatment, it’s worth considering whether the original diagnosis was correct. Mixed vaginitis, in particular, is often partially treated — one component is addressed while another remains.

The Role of Gut Health
Vaginal and gut health are more closely connected than most people expect. The gut microbiome influences immune regulation, systemic inflammation, oestrogen metabolism, and the populations of bacteria that colonise other mucosal surfaces — including the vagina.
When gut bacteria are out of balance — a state called dysbiosis — this can create conditions that favour yeast overgrowth and reduce the body’s ability to maintain a healthy vaginal microbiome. Women with chronic gut issues often notice correlations with recurrent vaginal symptoms, and this isn’t coincidence.
Supporting the gut microbiome through diet, reducing processed sugars, managing stress, and using targeted probiotics can therefore have a meaningful impact on vaginal health over time — not just gut comfort.

Natural Support Strategies
Medical treatment is sometimes necessary and appropriate — particularly for confirmed BV or severe yeast infections. But treatment alone often isn’t enough to prevent recurrence. A broader, more supportive approach tends to produce more lasting results.
Probiotics. Lactobacillus-dominant probiotics — particularly strains such as L. rhamnosus, L. reuteri, and L. crispatus — have been studied for their role in supporting vaginal microbiome health. Supporting the gut with a multi-strain broad-spectrum probiotic can also have downstream effects on vaginal balance.

Dietary changes. High sugar intake feeds Candida and disrupts the gut microbiome. Reducing refined sugars and processed foods — particularly during a flare — may help reduce the frequency of yeast-related episodes.

Eliminating irritants. Switch to unscented, pH-balanced products. Avoid douching. Wear breathable, natural-fibre underwear. These changes don’t replace treatment but they remove factors that can perpetuate inflammation.
Supporting immune function. Chronic stress, poor sleep, and nutrient deficiencies all compromise the immune system’s ability to maintain microbial balance. Addressing these foundational factors matters.
When to See a Healthcare Practitioner
Natural support strategies are valuable, but some situations require professional assessment:
- Symptoms that are severe, sudden, or accompanied by fever or pelvic pain
- Unusual bleeding alongside vaginal symptoms
- Symptoms that don’t improve with treatment, or return within weeks
- Pregnancy, or suspected pregnancy
- First-time symptoms (don’t assume — get a confirmed diagnosis)
A confirmed diagnosis via swab testing is important because different types of vaginitis require different treatment. Self-treating without knowing the cause can delay appropriate care and, in some cases, make recurrence more likely.
The Bottom Line
Vaginitis is inflammation of the vagina, and it can have many causes — yeast, bacteria, hormones, irritants, or a combination. Because symptoms overlap, misdiagnosis is common, and treating the wrong cause is one of the main reasons vaginitis keeps coming back.
A lasting approach addresses not just the current episode but the underlying environment: the gut microbiome, the vaginal microbiome, dietary factors, irritant exposure, and immune health. That’s more work than a single course of medication, but it’s what makes a real difference for women dealing with recurrent symptoms.
Frequently Asked Questions: Vaginitis Causes, Symptoms & Types
Vaginitis is inflammation of the vaginal tissues. It’s an umbrella term, not a single condition — it can be caused by yeast overgrowth, bacterial imbalance, hormonal changes, or chemical irritants. Because the causes overlap in symptoms, it’s commonly misdiagnosed.
The most common symptoms include vaginal itching or irritation, burning during urination, unusual discharge (changes in colour, smell, or texture), redness or swelling, and discomfort during sex. Symptoms can appear suddenly or gradually and may come and go.
The main types are yeast vaginitis (caused by Candida overgrowth), bacterial vaginosis (BV), hormonal or atrophic vaginitis (linked to low oestrogen), irritant or contact vaginitis (caused by soaps, scented products, or synthetic fabrics), and mixed vaginitis where more than one cause is present at once.
Recurrent vaginitis usually happens because only the symptoms were treated, not the underlying cause. Other factors include biofilm-protected bacteria or yeast that resist treatment, depleted Lactobacillus populations in the vagina, ongoing dietary or lifestyle triggers, and occasionally misdiagnosis.
Yes. The gut microbiome influences immune function, oestrogen metabolism, and the bacterial populations that colonise the vagina. An imbalanced gut can contribute to recurrent yeast overgrowth and bacterial shifts, making gut support an important part of managing vaginitis long term.
