Common Causes of Abnormal White Discharge
When discharge changes in texture, smell, or is accompanied by discomfort, the underlying white discharge causes fall into a few key categories.
Yeast Infection (Candidiasis)
Vaginal yeast infections are not usually considered sexually transmitted infections, and routine treatment of sexual partners is not recommended for uncomplicated cases. However, sexual activity may sometimes contribute to irritation or trigger symptoms in some women.
Bacterial Vaginosis (BV)
Symptomatic bacterial vaginosis is treated with antibiotics prescribed by a healthcare professional. Recommended treatments include medicines such as metronidazole or clindamycin, depending on the individual's circumstances.
Sexually Transmitted Infections (STIs)
Chlamydia, gonorrhoea, and trichomoniasis can all produce abnormal discharge, sometimes white or yellow-green, often with burning during urination or pelvic discomfort. STIs require specific testing and treatment; they do not resolve on their own.
Hormonal Shifts and Other Triggers
Stress, significant weight change, starting or stopping hormonal contraception, and perimenopause can all alter discharge patterns. Stress does not directly cause infection, but it can suppress immunity and indirectly allow yeast or bacterial overgrowth.
Pregnancy
However, itching, burning, unusual colour, or other changes in vaginal discharge during pregnancy should be assessed by a healthcare professional, as some vaginal infections and sexually transmitted infections can cause pregnancy complications or be transmitted to the baby if left untreated.
