The most common causes of vaginitis are from an infection:
- Vaginal yeast - caused by the overgrowth of yeast normally found in the vagina
- Bacterial vaginosis - caused by the overgrowth of bacteria normally found in the vagina
- Trichomoniasis - caused by a protozoathat is passed between sexual partners
Another type of vaginitis is atrophic vaginitis. This is an irritation of the vagina caused by thinning tissues and less moisture in the vaginal walls. This often occurs in menopause because of lower amounts of the hormone estrogen.
Other causes of vaginitis may include:
- scented panty liners, spermicide, soaps, and other perfumed products
- allergens including topical antifungal agents, semen, and latex
Symptoms may include:
- Irritation or itching of the vagina and/or genital areas
- Redness, pain, and swelling of genital area
- A change in vaginal discharge
- A change in vaginal odour
- Pain with sexual intercourse
- Discomfort while urinating (peeing)
Tests and Diagnosis
Your health care provider will do an exam and will take samples of the vaginal discharge. The samples will be sent to the lab.
Vaginal infections are common and often easily treated. It is best to see a health care provider to find out the cause of symptoms and the best treatment options. Yeast is treated with over-the-counter vaginal creams or medication that is available from a pharmacy. Bacterial vaginosis and trichomoniasis are treated with prescription antibiotics. Atrophic vaginitis is treated with prescription estrogen cream, rings or pills.
There are things you can do to prevent vaginitis:
- Avoid over use of antibiotics
- Avoid douching, feminine deodorant sprays and scented sanitary products
- Use unscented soaps or no soap on the genitals
- Avoid harsh laundry detergents and use a double rinse cycle
- Wear loose clothing and cotton underwear
- Use a condom during sex
- Use an unscented, glycerin-free lube
