The vaginal area should be washed with water. Perfumed soaps, shower gels, and vaginal deodorants should be avoided. Douching is not recommended. The practice upsets the normal balance of yeast in the vagina and does more harm than good.Prevention of bacterial vaginosis includes healthy diets and behaviors as well as minimizing stress as all these factors can affect the pH balance of the vagina.Prevention of trichomoniasis revolves around avoiding other peoples wet towels and hot tubs, and safe-sex procedures, such as condom use.Some women consume good bacteria in food with live culture, such as yogurt, sauerkraut and kimchi, or in probiotic supplements either to try to prevent candidiasis, or to reduce the likelihood of developing bacterial vaginitis following antibiotic treatment. There is no firm evidence to suggest that eating live yogurt or taking probiotic supplements will prevent candidiasis.Studies have suggested a possible clinical role for the use of standardized oral or vaginal probiotics in the treatment of bacterial vaginosis, either in addition to or in place of the typical antibiotic regimens. However, recent articles question their efficacy in preventing recurrence compared with other means, or conclude that there is insufficient evidence for or against recommending probiotics for the treatment of bacterial vaginosis. Treatment
The cause of the infection determines the appropriate treatment. It may include oral or topical antibiotics and/or antifungal creams, antibacterial creams, or similar medications. A cream containing cortisone may also be used to relieve some of the irritation. If an allergic reaction is involved, an antihistamine may also be prescribed.
"Further, there are complications which lead to daily discomfort such as:

persistent discomfort
superficial skin infection (from scratching)
complications of the causative condition (such as gonorrhea and candida infection)

Causes
Infection
Vaginitis is often caused by an infection or the disruption of the healthy vaginal flora. The vaginal flora consists of those organisms which generally do not cause symptoms and is dominated mainly by Lactobacillus species. Disruption of the normal flora can cause a vaginal yeast infection. Vaginal yeast infection can affect women of all ages and is very common. The yeast Candida albicans is the most common cause of vaginitis. Specific forms of vaginal inflammation include the following types:
Infectious vaginitis accounts for 90% of all cases in reproductive age women:

Candidiasis: vaginitis caused by proliferation of Candida albicans, Candida tropicalis, Candida krusei
Bacterial vaginosis: vaginitis caused by increased growth of Gardnerella (a bacterium). Aerobic vaginitisOther less common infections are caused by gonorrhea, chlamydia, Mycoplasma, herpes, Campylobacter, improper hygiene, and some parasites, notably Trichomonas vaginalis. Rare cases of amebic vaginitis have been reported, primarily in tropical, developing countries. Women who have diabetes develop infectious vaginitis more often than women who do not.Further, either a change in pH balance or introduction of foreign bacteria in the vagina can lead to infectious vaginitis. Physical factors that have been claimed to contribute to the development of infections include the following: constantly wet vulva due to tight clothing, chemicals coming in contact with the vagina via scented tampons, antibiotics, birth control pills, or a diet favoring refined sugar and yeast.
