Recurring Vaginal Infections: Why They Keep Coming Back and When to Seek Help
Experiencing repeated vaginal itching, unusual discharge or irritation? Understand possible causes, treatment options and when specialist gynaecological assessment may help.
Vaginal itching, unusual discharge, irritation or an unpleasant odour can be uncomfortable, especially when symptoms return after treatment.
Many women experience vaginal infections during their lives. However, when symptoms repeatedly return, it is important to understand whether the problem is an infection, a hormonal change or another condition with similar symptoms.
At Gynaeaesthetics London, Consultant Gynaecologist Mr Mohammad Masood provides personalised assessment for women's health concerns.
What Are Recurring Vaginal Infections?
Recurring vaginal infections refer to repeated episodes of infections affecting the vagina. Two common causes of vaginal symptoms are vulvovaginal candidiasis, also called thrush, and bacterial vaginosis (BV).
Although symptoms can overlap, these conditions are different and require different approaches to treatment.
Recurring symptoms do not always mean the same infection has returned. Skin conditions, hormonal changes, sexually transmitted infections and irritation from personal-care products can sometimes produce similar symptoms.
1. Recurring Vaginal Thrush
Vaginal thrush is usually caused by an overgrowth of Candida yeast.
Common symptoms include:
- Itching around the vagina or vulva
- Redness, irritation or soreness
- Thick, white vaginal discharge
- Burning during urination
- Discomfort during sexual intercourse
Recurrent vulvovaginal candidiasis is commonly defined as three or more symptomatic episodes within one year, although definitions vary between medical guidelines.
Contributing factors may include antibiotic use, diabetes, pregnancy, immune-system conditions and hormonal changes.
If thrush keeps returning, a clinician may recommend laboratory testing to confirm the diagnosis and identify the Candida species.
2. Bacterial Vaginosis (BV)
Bacterial vaginosis develops when the normal balance of vaginal bacteria changes. Unlike thrush, BV is not caused by yeast.
Symptoms may include:
- Thin, greyish-white discharge
- A noticeable fishy odour
- Mild vaginal irritation
- Occasional burning or discomfort
Some women with BV experience no symptoms. BV can recur after treatment.
Changes in the vaginal microbiome, sexual activity and vaginal douching may contribute to recurrence.
3. Why Do Vaginal Symptoms Keep Returning?
Antibiotic Use
Antibiotics can affect the normal vaginal bacterial environment, sometimes allowing yeast to multiply.
Hormonal Changes
Pregnancy, breastfeeding and menopause can influence vaginal tissue and the vaginal microbiome.
During menopause, declining oestrogen may cause dryness, irritation and discomfort that can resemble infection.

Diabetes and Blood Sugar Levels
Poorly controlled diabetes may increase susceptibility to certain yeast infections.
Irritating Personal-Care Products
Scented washes, vaginal deodorants and douching can irritate sensitive tissue or disrupt the vaginal environment.
Incorrect or Incomplete Diagnosis
Repeated itching or discharge is not always caused by thrush or BV.
Conditions such as contact dermatitis, vulval skin disorders and sexually transmitted infections may require different treatments.
4. Can Vaginal Infections Cause Pain During Sex?
Yes. Vaginal infections and inflammation can make sexual intercourse uncomfortable or painful.
However, persistent pain during sex may also be associated with pelvic floor dysfunction, vaginismus, hormonal changes or other gynaecological conditions.
If discomfort continues after infection treatment, further assessment may help.

5. How Are Recurring Vaginal Infections Diagnosed?
A gynaecological assessment may involve reviewing symptoms, previous treatments, menstrual history and possible contributing factors.
Investigations may include:
- Clinical examination with consent
- Vaginal swabs
- Microscopy or laboratory testing
- Sexually transmitted infection testing
- Blood glucose testing when appropriate
Not every patient requires every investigation. The goal is to identify the underlying cause and develop an appropriate treatment plan.
6. Treatment Options for Recurring Vaginal Infections
Treatment depends on the confirmed diagnosis.
Treatment for Recurring Thrush
A clinician may recommend a longer initial antifungal treatment course followed by maintenance treatment in selected cases.
Treatment for Recurrent BV
Antibiotic treatment or a suppressive regimen may be considered based on clinical guidance and individual circumstances.
Avoid repeatedly using over-the-counter antifungal medication without confirming the diagnosis. Pregnant women should seek medical advice before using treatments, as some medications are unsuitable during pregnancy.
Probiotics are sometimes promoted for vaginal health, but evidence is insufficient to recommend them as a reliable replacement for established treatment.
7. How Can You Support Vaginal Health?
Simple daily habits may help reduce irritation and support comfort.
- Avoid vaginal douching
- Use gentle, unscented products externally
- Avoid unnecessary scented intimate sprays
- Change out of damp clothing after exercise
- Follow prescribed treatment instructions
- Seek testing when symptoms repeatedly return
The vagina is naturally self-cleaning. Internal washing is not necessary.
8. When Should You See a Gynaecologist?
Arrange medical assessment if:
- Symptoms return after treatment
- You experience persistent itching or burning
- Unusual discharge continues
- You develop pain during intercourse
- You experience unexplained vaginal bleeding
- Symptoms appear after new sexual contact
- Treatment does not improve your symptoms
Seek prompt assessment if symptoms occur with fever, significant pelvic pain or pregnancy-related concerns.
For persistent pelvic discomfort, learn about specialist pelvic pain care.

Frequently Asked Questions
Why does thrush keep coming back after treatment?
Recurring thrush may be associated with antibiotic use, diabetes or particular Candida species. Testing can help confirm whether symptoms are caused by thrush or another condition.
Is bacterial vaginosis a sexually transmitted infection?
BV is not classified as a conventional sexually transmitted infection, although sexual activity can influence the vaginal microbiome and recurrence risk.
Can menopause cause symptoms similar to a vaginal infection?
Yes. Menopause-related vaginal dryness and inflammation may cause burning, irritation and discomfort. A specialist can help distinguish these symptoms from an infection.
Can I treat recurring vaginal infections at home?
Some uncomplicated infections can be managed with appropriate pharmacy treatment. However, repeated or persistent symptoms should be medically assessed.
Can vaginal infections affect fertility?
Most uncomplicated vaginal thrush infections do not affect fertility. However, certain sexually transmitted infections can lead to pelvic inflammatory disease, which may affect fertility if untreated.
Should my partner also receive treatment?
Partner treatment depends on the diagnosis. It is not routinely recommended for uncomplicated vaginal thrush, while guidance for BV and sexually transmitted infections differs. Discuss individual circumstances with your clinician.
