Prevention of vaginal discharge depends on the cause. Candida infections can be prevented by avoiding a humid environment around the genital area. This can be done by wearing loose-fitting and absorbent clothing. Women should practice good hygiene methods, such as bathing, showering, wiping front to back after urinating, and frequent handwashing. Practicing safer sex and having fewer sexual partners should reduce the chances of spreading STDs. Hormone replacement therapy can prevent atrophic vaginitis caused by low levels of estrogen.
Normal vaginal discharge does not need treatment. Feminine hygiene products and douching should not be used. These products can mask the symptoms of an sexually transmitted disease as well as force the bacteria higher into the pelvic organs. These products may cause a contact dermatitis to the vulva and vaginal tissues.
With proper treatment, there are usually no long-term effects. However, certain causes may not be completely curable. Some of these include herpes, human papillomavirus (HPV), and HIV. If a severe long-standing STD has spread to the pelvic organs, pelvic adhesions may occur. This can lead to long-term pain and infertility.
Normal vaginal discharge poses no risk to others. If there is an underlying infection, such as a sexually transmitted disease, the infection may be highly contagious through sexual contact.
