Vaginitis is the term used to describe inflammatory conditions affecting the female vagina. It is sometimes called vaginalmucositis. Vaginitis may be associated with vulval conditions.
Vaginitis may result in vaginal soreness, itching, discharge, malodour, fissuring and bleeding. It may hurt to pass urine (dysuria). It may prevent sexual intercourse (apareunia) or result in painful or uncomfortable sexual intercourse (dyspareunia).
What are the causes of vaginitis?
Although most often due to infection, vaginitis may be due to one or more causes. These include:
Injury to the vagina, including after childbirth, intercourse, sexual assault, trauma or surgery
Infection, tumour or injury resulting in a fistula from the bladder draining urine or from the rectum leaking faeces
A foreign body within the vagina, for example, a retained tampon
Contact irritant reaction, for example, to douching with water and soap or bubble bath, or contact with semen, saliva, lubricant, fragrance or topical medicament (see contact irritant dermatitis)
Menstrual bleeding usually occurs for a few days at regular monthly intervals. Intermenstrual spotting can be quite normal. However, vaginal bleeding after established menopause may be serious and requires investigation as it may be an important sign of early cervical or endometrial cancer.
Vaginal dryness
Vaginal dryness is a common problem that significantly reduces women's enjoyment of sex. It is due to reduced vaginal natural lubrication, and it can also be a sign of vaginitis.
Normal vaginal discharge is produced by mucousglands in the cervix and vagina, which mix with desquamating cells from the lining of the vagina. During arousal (orgasm), additional musk-smelling fluid is produced by the Bartholin glands at the entrance to vagina to reduce friction caused by penetration of a penis.
Lack of oestrogen due to menopause or infancy reduces vaginal mucus production. This may cause atrophic vaginitis, resulting in postmenopausal dryness, burning and lack of sexual desire (decreased libido).
Vaginal dryness in premenopausal women may be caused by menstrual cycle hormonal fluctuations, pregnancy or Sjögren syndrome. Certain medications may dry up normal vaginal fluids, such as some oral contraceptive pills, depot progesterone injections, sedatives, heart pills, cold or allergy medicines.
Investigations for vaginitis
Vaginitis is evaluated by speculum examination of the vagina and cervix, as well as an examination of the abdomen, groin and vulva. In some cases, examination under anaesthetic (EUA) is necessary, including hysteroscopy (examination of the inside of the womb). Other investigations may include:
Evaluation of vaginal pH
Wet mount and high vaginal swabs for microscopy, culture and sensitivity.
Microscopy of a wet smear evaluates epithelial cells and patterns of micro-organisms. The results may be difficult to interpret, as bacteria and yeasts may be found in the normal vaginal flora.
In general, the vagina does not need to be washed (douched), as it regularly cleans itself. Gently cleanse the outside skin with water. A non-soap cleanser may be used.
Water-based vaginal lubricant before and during sex, or a vaginal moisturiser inserted several times each week, can make intercourse easier and less uncomfortable.
