Vaginal Discharge - Types, Causes, Symptoms, Treatment, Prevention

Vaginal discharge meaning 

Vaginal discharge is a mixture of fluid comprising bacteria, mucus (liquid) and dead cells secreted by the cervix and vagina to protect the vagina by maintaining the PH, lubricating it, moistening, and keeping it clean.

It is a natural secretion of the female reproductive system, The vagina starts making discharge during the puberty. It is a way for the body to respond to any hormones that are secreted in the body. Thus, it is also a mechanism for protecting the vagina from various diseases or infections.

The amount and consistency of the discharge may vary from one woman to another. Vaginal discharge can change (amount, colour and consistency) during the woman's menstrual cycle and over the years. It may become more apparent at specific times, such as during pregnancy, during sexual arousal, ovulation, luteal phase, puberty, and with estrogen-based therapies such as combined hormonal contraception and hormone-replacement therapies.

Vaginal discharge during pregnancy is completely normal. This helps prevent any infections that travel from the vagina to the uterus. Normal vaginal discharge during pregnancy comes in more significant amounts.

Types of vaginal discharge during pregnancy

These are the following types that a pregnant woman experiences include Leucorrhoea, mucus plug, bloody show, watery discharge, increased mucus.

• Vaginal discharge during early pregnancy (vaginal discharge early pregnancy) is clear, thin, or milky white and smells only mildly. 
• Most pregnant women notice increased (excessive) vaginal discharge in early pregnancy (first trimester) and throughout the pregnancy due to hormonal fluctuations (increased estrogen) and increased blood flow to the pelvic area. This is called leucorrhoea.
• Women experience pinkish mucus or brownish vaginal discharge may occur at the second and third trimester. It indicates that blood is leaving the body with normal discharge in small amounts.
• During incubation (pregnancy), a mucus plug seals the cervix's opening to prevent the infections from entering the womb.
• When the cervix starts dilating in preparation for labour, the plug will come out. This is called a "show" and appears watery, sticky or jelly-like. It might contain blood or appear brown or pink. 
• At the end of pregnancy, the female body produces more vaginal discharge as sticky, jelly-like pink mucus streaks.

Smelly vaginal discharge during pregnancy may occur due to yeast infection, spicy foods and scented soaps. Other causes include vaginitis, bacterial vaginosis, dehydration, etc. Pregnant women can have a higher chance of developing vaginal thrush or bacterial vaginosis (causing unusual vaginal discharge). 

Abnormal vaginal discharge during pregnancy may look like cottage cheese or froth, green, yellow, grey or brown, have a foul smell and is associated with pain or irritation around the vagina.It indicates the abnormality.

Normal vaginal discharge colour is white, creamy or clear, with sometimes a slight yellow tint, and it has no noticeable odour (odourless) or irritation. 

• Vaginal discharge during menstruation: Usually, healthy vaginal discharge changes in odour and consistency during the menstrual cycle. It is bloody or dark brown from the first to the fifth day of menstruation. From the sixth to the 14th day, it becomes clearer and thinner in consistency. 
• Vaginal discharge during ovulation: Usually, during ovulation or nearing the ovulation, colour of normal vaginal discharge becomes egg-white and thicker or slippery in consistency. This is an indication that a woman is ovulating.
• Vaginal discharge before period: After ovulation, the amount of vaginal discharge usually decreases and becomes thicker in consistency. This happens between days 25 to 28, just before the next menstrual cycle. During this time, the discharge may appear a little whitish and have a lumpy or clumpy texture. A vaginal discharge is normal until and unless associated with any itching, pain, or foul smell.
• Vaginal discharge before missed period can differ based on several factors and may not always indicate pregnancy.
• Female vaginal discharge (at Premenopausal stage) usually has around 2 to 5 mL (one-half to one teaspoon) of white or clear, thick, mucus-like and primarily odourless vaginal discharge daily. 
• After menopause, estrogen levels will decrease, usually reducing the amount of normal discharge.

The female vagina contains a lot of good bacteria called lactobacilli that help clean and maintain the vaginal PH (slightly acidic), keeping it healthy. If the balance of good bacteria is disturbed and there is an overgrowth of yeasts or harmful bacteria, it may result in abnormal vaginal discharge. A disturbance in the balance of healthy bacteria can affect the vagina discharge and lead to changes in it. 

Abnormal vaginal bleeding is characterised by changes in odour, colour, volume and consistency with symptoms such as dysuria, pelvic pain, itching, soreness or intermenstrual or post-coital bleeding. Unusual or abnormal vaginal discharge is usually an indication of infection or inflammation.

All types of vaginal discharge that present in females based on multiple factors. However, based on the colour, the following are the different types of vaginal discharge:

Types of vaginal discharge and what they mean

• White vaginal discharge: White or clear discharge usually indicates the normal vaginal discharge. It is common, particularly at the start or end of the menstrual cycle. It will be sticky and thick with no noticeable smell. It helps balance the vaginal health, and if it is thick, clumpy and associated with pain or itching (white vaginal discharge and itching), it could indicate infection or other medical issues. Usually, it indicates the cleaning of the vagina itself to prevent infection.
• Brown vaginal discharge:  Brown or red discharge is commonly seen during menstrual periods. If one has a red-brown tinged discharge, and it is not related to menstruation, it may indicate a problem. Colours might change from cherry red at the beginning of the menstrual period to rusty brown.
• Pink vaginal discharge: Having a pink discharge (a reddish, pink or brown without smell) at the beginning days before the period starts or after it ends in a woman of childbearing age is considered normal.
• Yellow vaginal discharge: Very light-yellow colour discharge is expected. If it is yellow-green appearance is there, then it indicates a sign of infection.
• Green vaginal discharge: It is not normal (abnormal) and needs medical attention. If the vaginal discharge is thick, clumpy, or foul odour, it may indicate infection or other medical conditions.
• Gray vaginal discharge: Gray vaginal discharge is not normal or healthy, and it can be a sign of infections.
• Watery vaginal discharge: It helps to clean the vagina and is free from infections. Healthy bacteria in the vagina help make acidic secretions, which help fight against harmful bacteria and clear out dead cells.
