Vaginal Discharge

Vaginal discharge is a physiological phenomenon and some form of discharge is considered as absolutely normal. But there are some conditions or disorders of women those are recognized as well as manifested by the change in amount, color, consistency, duration or even smell of the vaginal discharge. Thus, it is of utmost importance to know the difference between a normal and an abnormal vaginal discharge.

What are the different types of vaginal discharges?

1. Normal vaginal discharge (Leucorrhoea):

Almost all women experience some form of vaginal discharges at any point in time. This is usually clear or milky or more like a sticky liquid. These are the secretions from the glands situated in the vagina and cervix. This constant secretion helps in vaginal lubrication, clears out old cells, keeps the vagina clean and safe from outside infections. Usually, it amounts 1 to 4 ml in 24 hours in a normal reproductive-aged woman.


The discharge can be seen within the first few days after birth due to estrogen exposure from mother, within the womb. It looks more like a clear or white mixture with a mucus type of texture.


The secretion is comparatively thinner and has a different bacteria flora.


As the production of estrogen begins at this age, there is an increase in the vaginal discharge along with an increase in glycogen content leading to increased lactobacilli content in the vagina. This, in turn, leads a to more acidic environment inside the vagina which helps to protect the vagina from outer infections.

Menstrual cycle:

In the normal menstrual cycle, there is some form of vaginal discharges which are considered normal. During the mid-cycle, there is an increase in vaginal secretion which is an indicator of ovulation.


During pregnancy, due to an increased level of hormones inside the mother's body, the vaginal secretion is increased but without any itching or foul smell. The secretion is commonly white or mildly grey in color associated with a musty smell.


Vaginal secretions decrease after menopause due to the effect of a decrease in sex hormone production inside the body.

2. Abnormal vaginal discharge:

Various conditions and different types of infections and diseases can be reasons for changed vaginal discharges. The discharge might change in color, amount, consistency, duration and could be associated with offensive smell or itching.
