What is yeast infection (thrush)?
Thrush is a fungal infection caused by Candida species, commonly affecting the vagina, mouth, or skin folds. It occurs when the natural balance of microorganisms is disrupted, leading to overgrowth of yeast.
Thrush is common in women, but can affect men and children. It is not usually dangerous but can cause discomfort and affect quality of life.
What causes thrush?
- Overgrowth of Candida albicans
- Antibiotic use disrupting normal bacterial flora
- Hormonal changes (pregnancy, contraception)
- Diabetes or immune suppression
- Moist, warm environments
Common triggers:
- Poorly controlled diabetes
- Recent antibiotic or steroid therapy
- Tight, non-breathable clothing
- High sugar diet
What are the common symptoms of thrush?
You may notice:
- Vaginal itching, irritation, or soreness
- Thick, white “cottage cheese” discharge
- Burning during urination or sex
- Redness and swelling of the vulva
- Oral thrush: white patches in the mouth, soreness, or difficulty swallowing
How is thrush diagnosed?
Diagnosis is usually clinical:
- Symptom history and examination
- Swabs may be taken if diagnosis is uncertain or recurrent
Online GP consultations are suitable for symptom assessment and prescription. In-person review may be needed if:
- Infection is recurrent
- Symptoms are severe
- Swab tests are needed to confirm species
How long does thrush last?
- Mild cases: 1–7 days with treatment
- Severe or recurrent cases: may require longer therapy
Is thrush contagious?
Thrush is not typically sexually transmitted but close contact can transmit yeast.
