A little vaginal discharge is normal and occurs in every woman. As part of normal body function, the daily secretion of secretions may vary from woman to woman and the amount of discharge may change during the cycle. A healthy vaginal flora, including vaginal discharge, prevents the penetration and proliferation of germs and ensures the correct vaginal acidity level. Bacterial infections, fungal infestation and viruses can cause vaginal discharge. Taking antibiotics also disturb the vaginal flora, resulting in an imbalance that provides a better breeding ground for pathogenic germs or fungi. They can cause symptoms such as redness, itching, burning, pain in the vaginal area, extreme dryness or a coloured or foul-smelling discharge.
