You can have medications to be applied into the vagina, that contain lactobacilli and thus help in creating an acidic pH in the vagina. Use of estrogen
creams also helps if thinned out epithelium is another cause. If you are menstruating normally, this helps to maintain an acidic atmosphere. If you have attained menopause
or are nearing it, you may consider hormone replacement
. Please ask your consultant to prescribe medication to improve the acidic content of the vagina. Please see if your partner also needs treatment. Maintain proper genital hygiene. Hope this helps.
