Vaginal thrush is a common problem, usually diagnosed by its symptoms. However, similar symptoms can be experienced with other conditions, too, and therefore caution with self-care is advisable.
The thrush is usually caused by a fungus known as candida albicans, which exists naturally on the skin, mucous membranes and the gastrointestinal tract. In certain conditions, the amount of candida multiplies excessively, causing an infection. Factors increasing the risk of thrush include, among other things, antibiotics, the Pill, pregnancy, diabetes and other conditions which weaken the immune system. Tight clothing and contact with sanitary pads may also cause thrush.
Vaginal itching is not necessarily a thrush symptom, but may be caused by another gynaecological condition. Sometimes mild itching is caused by cytolysis, bursting of vaginal cells, as a result of loss of vaginal acidity. This is normal, but acidic vaginal discharge may cause symptoms on the vulva.
