Vaginal discharge is a fluid that comes out of your vagina, which can vary in colour, including clear, off-white, white, green, yellow, and brown. The uterus, cervix and vagina produce vaginal discharge, which is usually made of cells and bacteria. It helps in cleaning your vagina, and in preventing harmful bacteria. The discharge from your vagina is a normal and natural process, but any change in its colour and smell can be a warning sign of infection or disease.

Normal and regular vaginal discharge is a sign of a healthy reproductive system. The vaginal discharge contains a lot of materials including, vaginal fluid, cervical mucus, dead cells, and bacteria. Listed below are seven possible causes of vaginal discharge: 

1. Hormonal imbalances

Hormonal imbalances caused due to stress, poor diet, or any other underlying health conditions can lead to more vaginal discharge. Polycystic ovary syndrome (PCOS) symptoms are caused by hormonal imbalances, and can also result in vaginal discharge.

2. Arousal

Another possible cause of vaginal discharge is sexual arousal as it can trigger many physical responses in a woman's body. Arousal leads to an increase in the blood flow in your genitals.

Arousal fluid is mostly clear and watery and has a slippery texture, and also helps in lubricating the vagina while having sex.

Vaginitis is a condition which causes inflammation of the vagina, which develops due to an infection or factors like douches, lubricants, and poorly fitted clothing. Vaginitis can result in thick vaginal discharge, which may be white, grey, yellow, or green.  Some other symptoms of vaginitis are foul vaginal odour, an itching or painful burning in the genital area, and redness, inflammation in the vagina.

Vaginal yeast infections can cause vaginal discharge and these happen if a particular fungus, called candida grows out of control in your vagina. It can result in a thick and white vaginal discharge. Your vagina may also swell and get itchy, and can cause painful sex. Yeast infections are treatable with antifungal medications.

5. Bacterial vaginosis

Bacterial vaginosis is a condition which is caused by a bacteria overgrowth in the vagina. The infection is usually seen in women of the age group 15-44 years.
