Infection — Candida trachomatis is a common cause of infection. In addition, the bacteria that normally inhabit the vagina can multiply for unknown reasons and cause a strong-smelling vaginal discharge. This is known as non-specific vaginitis.

What are the causes of vaginitis ?

Vaginitis has various causes. It may result from bacterial infections, fungal infection, protozoan infection, contact dermatitis or even an allergic reaction. The main causes of vaginitis are irritation of the vagina by external factors, like cuts, abrasions in this region, constant wearing of tight-fitting clothes and wearing unclean clothes, using dirty or infected water and lack of hygiene.

Certain medications and treatments can increase susceptibility to infection. These include the use of antibiotics, hormones and excessive douching. Susceptibility is greater in cases of pregnancy, diabetes, and certain psychological conditions as well as during the latter half of the menstrual cycle. Irritation from contraceptive devices can also lead to this condition.

What causes bacterial vaginosis?

Bacterial vaginosis occurs when the natural balance of organisms in the vagina is changed. The healthy vagina normally contains a variety of bacteria. One type of “good” bacteria, Lactobacillus , is particularly important because it keeps the vagina slightly acidic to reduce the growth of potentially harmful organisms. When these bacteria are replaced with different kinds of “bad” bacteria, called anaerobic bacteria, an unpleasant vaginal odor develops and an infection (vaginitis) occurs.
