Vaginal yeast infections are one of the most common vaginal conditions affecting women in Singapore. While they are not life-threatening, they can cause significant discomfort and distress. Many women may also feel embarrassed to seek medical help.
In Singapore, the warm and humid climate increases the likelihood of yeast infections. Understanding the causes, symptoms, diagnosis, and treatment options can help you recognise when to seek care and how to reduce recurrence.

What Is Vaginal Yeast Infection?
A vaginal yeast infection, also known as vaginal thrush or vulvovaginal candidiasis, is caused by an overgrowth of Candida species, most often Candida albicans.
Candida organisms normally exist in the vagina without causing harm. When the balance of bacteria and yeast is disrupted, Candida can multiply and lead to infection.
Quick facts:
- About 75% of women will experience at least one episode in their lifetime.
Yeast infections are not classified as sexually transmitted infections (STIs), though sexual activity may trigger symptoms.
Causes and Risk Factors
A vaginal yeast infection develops when the balance of bacteria and yeast in the vagina is disrupted, allowing Candida to overgrow. Several factors can increase this risk:
Antibiotics
May reduce healthy vaginal bacteria, allowing yeast to multiply.
Sexual Activity
Can alter vaginal pH and sometimes trigger symptoms.
Hormonal Changes
Pregnancy, use of hormonal contraceptives, or menopause can alter vaginal flora and increase susceptibility.
Dietary factors
High sugar intake may play a role in recurrent infections for some women.
Diabetes
Poorly controlled blood sugar may weaken the immune response and promote yeast overgrowth. Recurrent thrush may sometimes be an early sign of undiagnosed diabetes.
Weakened immune system
Conditions such as HIV, or medications like steroids or chemotherapy, can reduce the body’s ability to control yeast growth.
Vaginal Washes and Douching
These can upset the natural pH balance and irritate the skin, contributing to infection.
Tight or non-breathable clothing
Warm, humid conditions, especially in Singapore’s climate, create an environment where yeast can thrive.
Symptoms of a Vaginal Yeast Infection
A yeast infection can cause a range of discomforts that vary from mild to severe. The most common symptoms include:
- Itching or burning in the vaginal or vulvar area
- Abnormal vaginal discharge – thick, white, often compared to “cottage cheese”
- Redness and swelling of the vulva
- Pain or discomfort during sexual intercourse
- Burning sensation during urination
- Cracks or dryness of the skin in severe or recurrent cases

Normal vs Yeast Infection Discharge
| Feature | Normal vaginal discharge | Yeast infection discharge |
|---|---|---|
| Colour | Clear to white | Whitish, yellowish or greenish |
| Consistency | Thin, slippery (varies with cycle) | Thick, “cottage cheese-like” |
| Odour | Mild or none | Usually none |
| Associated symptoms | None or mild | Itching, burning, redness, soreness |
| Vaginal pH | ≤ 4.5 (physiological) | ≤ 4.5 (unchanged) |

How Yeast Infections Differ from Other Vaginal Infections
Many vaginal infections cause similar symptoms, such as itching, discharge, and irritation — making it difficult to tell them apart based on symptoms alone.
- Yeast infection (Candida): Thick, white discharge without odour, with itching or burning.
- Bacterial vaginosis (BV): Thin, grey or white discharge with a noticeable “fishy” smell.
- Trichomoniasis: Frothy, yellow-green discharge, sometimes with a strong odour.
📌 Because the symptoms often overlap, a medical examination and tests are needed for an accurate diagnosis.
Vaginal Yeast Infection Diagnosis in Singapore
Accurate diagnosis is important because the symptoms of a yeast infection can resemble those of bacterial vaginosis (BV), trichomoniasis, or some sexually transmitted infections.
In Singapore, diagnosis usually involves:
- Clinical examination – A doctor checks for redness, swelling, and discharge.
- Vaginal swab test – A sample of discharge is taken and examined under a microscope to look for yeast cells.
- Culture or PCR testing – Sometimes recommended for recurrent or resistant infections to confirm the Candida species and guide treatment.
Why it matters: Over-the-counter antifungal creams may temporarily relieve symptoms but can delay correct treatment if the condition is actually BV, trichomoniasis, or an STI. A medical consultation ensures the right diagnosis and care.

Treatment Options for Vaginal Yeast Infections
Treatment depends on the severity of symptoms, whether the infection is recurrent, and if you are pregnant or have other medical conditions.
Simple Infections
Most first-time or mild yeast infections respond well to antifungal medications. These may be prescribed as:
- Topical antifungals – applied directly to the affected area as creams, ointments, or vaginal pessaries
- Oral antifungals – tablets that may be prescribed depending on the severity of symptoms or recurrence.
Treatment courses usually last between 1 and 14 days, depending on the medication and severity.
Severe or Recurrent Infections
Infections that are prolonged, severe, or recur frequently may require a more tailored approach:
- Extended courses of antifungals – weeks to months rather than days
- Culture testing – to identify the specific yeast strain involved
- Maintenance therapy – sometimes prescribed to reduce recurrence
- Monitoring – blood tests may be needed for long-term oral antifungal use
Why it matters: Severe or recurrent infections may not resolve with standard short-term treatment and need closer medical supervision.
When Treatment Fails
Occasionally, symptoms persist or return despite treatment. This may indicate misdiagnosis, resistant yeast strains, or underlying health issues.
| Scenario | Likely issue | Next step |
|---|---|---|
| Symptoms persist after treatment | Misdiagnosis or mixed infection | Re-examination, pH test, microscopy; rule out BV, trichomoniasis, or STIs |
| Recurs ≥4 times per year | Recurrent vulvovaginal candidiasis | Culture/speciation; consider maintenance regimen |
| Poor response to azole antifungals | Non-albicans Candida (e.g. C. glabrata) | Culture-guided therapy; alternative antifungals |
| Pregnancy with persistent symptoms | Limited medication options | Topical-only approach; obstetric review |
Recurrent or Complicated Vaginal Yeast Infections
A yeast infection is considered recurrent if it happens four or more times in a year. Risk factors include:
- Underlying conditions – diabetes, HIV, or frequent antibiotic use
- Resistant Candida species – some are harder to treat with standard antifungals
- Immune suppression – due to illness or medications
Long-term or maintenance antifungal therapy may be recommended to reduce frequency and severity of episodes.
Doctor’s Insight:
Dr. Chia has personally successfully treated several women with recurrent vaginal or yeast infection issues. It is key to first understand and identify the root cause of the problem with the proper test and diagnosis to ensure the right treatment plan is administered. Many times, other kinds of infection are mistakenly presumed to be yeast infections and hence incorrectly treated. So it is important to consult an experienced women’s health doctor for proper guidance on the right treatment for this condition.
Prevention of Yeast Infection and Lifestyle Tips
Recurrent yeast infections are common. They often occur when habits or environmental factors disturb the natural balance of vaginal bacteria and pH, leading to overgrowth of Candida.
Yeast infections are not caused by poor hygiene or dirty toilet bowls, a common misconception.
Hygiene Tips
- Avoid soaps, vaginal washes, or douching — rinse with water only.
- Do not use deodorants or perfumed products around the vaginal area.
- Change sanitary pads or tampons regularly.
- Avoid wearing pantyliners when not on your period.
Clothing and Moisture Management
- Wear breathable cotton underwear instead of synthetic fabrics.
- Avoid tight clothing that traps heat and moisture, especially in Singapore’s humid climate.
- Change out of damp clothes (after exercise or swimming) promptly.
Sexual Health
- Wash yourself before and after sexual intercourse.
- Use condoms to reduce irritation and protect against other infections.
- Limit multiple partners, as frequent exposure may disrupt vaginal balance.
Lifestyle and General Health
- Maintain good blood sugar control if you have diabetes.
Reduce high-sugar foods, which may worsen recurrence in some women. - Support your immune system with adequate sleep, stress management, and balanced nutrition.
Complications if Left Untreated
While vaginal yeast infections are not usually dangerous, untreated cases may:
- Cause persistent itching and soreness
- Lead to skin cracks and irritation
- Delay treatment of BV, STIs, or UTIs due to misdiagnosis
- Cause pregnancy-related discomfort or risk of complications
When to See a Doctor in Singapore
Seek medical advice if:
- Symptoms persist despite over-the-counter medication
- Infections recur frequently
- You are pregnant, diabetic, or immune-compromised
- You develop severe pain or unusual discharge

Prevention of Yeast Infection and Lifestyle Tips
Recurrence is an extremely common problem that is troubling for many, and oftentimes it is because of their feminine hygiene habits that contribute to this.
It is important to understand that it is caused by the disruption of the balance and natural pH of the vaginal flora (good bacteria), which leads to the overgrowth of candida.
This is caused by factors such as – over washing the vagina with soaps, vaginal douching, moist environment with tight clothing, sexual intercourse which causes irritation to the vagina.
They are in fact, not caused by poor hygiene or by the use of a dirty toilet bowl.
Here are some important tips for prevention:
- Avoid soaps around the vagina, wash with water only
- Avoid vaginal douches and wash
- Avoid deodorants or perfumed products around the vagina
- Avoid tight clothing or underwear
- Change your pad or tampon regularly
- Avoid wearing pantyliners when not on your period
- Wash yourself before and after sexual intercourse
- Stick to a regular partner and have protected sexual intercourse with a condom
