hi,, your vaginal discharge is grey or develops a strong fishy smell, particularly after sexual intercourse, you could have bacterial vaginosis (BV). BV is an imbalance in the normal bacteria found in your vagina. It does not usually cause itching or irritation. Like thrush, BV is very common and is not sexually transmitted. It is easily treated with antibiotics. See your doctor. In diagnosing bacterial vaginosis, it is important to exclude other serious infections, such as gonorrhea and Chlamydia. At present, it seems to be that a combination of multiple bacteria must be present together for the problem to develop. Bacterial vaginosis typically features a reduction in the number of the normal hydrogen peroxide-producing lactobacilli in the vagina. Simultaneously, there is an increase in concentration of other types of bacteria, especially anaerobic bacteria (bacteria that grow in the absence of oxygen). As a result, the diagnosis and treatment are not as simple as identifying and eradicating a single type of bacteria. Why the bacteria combine to cause the infection is unknown both the partners will require treatment. . byeeeeeeeeee
