Vaginal discharge is the clear, white, or off-white fluid released from the vagina. It carries away dead cells and bacteria, helping to keep the reproductive system clean. It is a natural process and an essential aspect of a woman’s reproductive health. It helps maintain the vagina’s cleanliness and protects it against infections.
It may vary in colour, consistency, and odour, indicating underlying health conditions. But which colour, consistency, and odour is normal and which is alarming can be a question of concern. A normal vaginal discharge does not cause itching, redness, and swelling and is generally odour free. If your discharge is showing unusual symptoms and odour, it can indicate any underlying infection, health condition, or an unhealthy lifestyle.
Is it Normal to have vaginal discharge?
Vaginal discharge is a natural process, and it is absolutely normal to have it. White vaginal discharge without a foul smell is commonly experienced during pregnancy or sexual arousal due to hormonal changes. During arousal and intercourse, increased blood flow and hormonal changes can influence the amount and consistency of vaginal secretions. Additionally, certain contraceptives, such as hormonal birth control methods, may alter the vaginal environment, affecting the normal vaginal discharge.
This discharge helps protect the reproductive organs and prevent infections. Vaginal discharge throughout the menstrual cycle is also normal. The consistency, colour, and quantity of discharge can change due to hormonal imbalance or specific health conditions.
The other common conditions where vaginal discharge is expected include:
- Use of Tampons: A tampon stuck between the cervix and vagina can also cause vaginal discharge.
- Atrophic vaginitis: It is a post-menopausal condition that causes the vagina to be dry and thin than usual.
- Cervical ectropion: It is a common gynaecological condition that causes the vaginal discharge.
- Vulval dermatitis: it is the condition when the vulva, the soft folds of skin around the opening of the vagina, becomes inflamed and itchy.
- Allergic reaction: Any allergic reaction from non-medicated soaps, detergents, genital sprays, ointments, contraceptive jellies, foams, or creams.
What are the different types of vaginal discharge?
There are 2 types of vaginal discharge:
1. Normal discharge
The vaginal discharge is normal when it is clear or milky with slight or no odour. It is thick and has sticky consistency that keeps the vagina bacteria-free. The black vaginal discharge after periods is also expected. When blood is in the uterus after the menstrual cycle for an extended period, it undergoes oxidation, resulting in a brownish to dark brown or black hue.
2. Abnormal discharge
The vaginal discharge is abnormal when it is dark yellow, grey, or green with a thick consistency and a foul smell. It may be an alarming sign of a bacterial infection or an underlying disease. It may cause itchiness, soreness around the vagina, and painful urination. The pink or red discharge before periods is also considered abnormal. It can be indicative of cervical bleeding, vaginal irritation, or implantation bleeding.
Colour of Vaginal Discharge and Its Causes
The color of vaginal discharge can vary and often indicates different health conditions. Clear or white discharge is normal, while yellow, green, or gray discharge may signal infections. Brown or bloody discharge can occur around menstruation or signal other issues. Identifying these colors helps in understanding potential causes. The following table describes different vaginal discharge and their causes.
| Colour of vaginal discharge | Cause of vaginal discharge |
| Clear or white | Normal or healthy discharge |
| Curdy white | Vulvovaginal candidiasis (Fungal or yeast infection) |
| Greyish white | Bacterial vaginosis (Bacterial infection) |
| Yellow or green | Neisseria gonorrhoeae (STI) |
| Yellowish green | Trichomonas vaginalis (STI) |
| Pink | Cervical bleeding, vaginal irritation, or implantation bleeding |
| Red | Menstruation, cervical cancer, or uterine cancer |
| Brown | Old blood or an irregular menstrual cycle |
Which infections cause vaginal discharge?
Abnormal vaginal discharge can occur due to various infections as well. These include:
Non-Sexually Transmitted Infections
- Bacterial vaginosis: The abnormal vaginal discharge due to bacterial infection can cause fish-smelling discharge. It is usually without itch or soreness. The discharge consistency is thin and is of either grey or white colour.
- Vulvovaginal candidiasis: The abnormal vaginal discharge due to fungal or yeast infection. It is usually with itch, soreness, and causes curdy white vaginal discharge, which does not usually smell.
Sexually Transmitted Infections
- Chlamydia trachomatis: It is a bacteria that can transmit through vaginal, oral and anal sex. In postpubertal women, it infects the endocervix instead of the vagina. It leads to cervical discharge, which seems as if it is a vaginal discharge with pelvic pain or vaginal bleeding.
- Neisseria gonorrhoeae: It is a sexually transmitted disease marked by an abnormal yellow or green vaginal discharge that may be thin or watery, purulent (containing pus), and with mild odour.
- Trichomonas vaginalis: It is a parasitic infection that causes the abnormal vaginal discharge. It may be thick, thin, or frothy and yellowish-green in colour. This infection may produce more discharge than usual, which may also have an unpleasant fishy odour. You can also experience soreness, swelling, and itching around the vagina and inner thighs.
- Herpes simplex virus (HSV): It is a sexually transmitted virus that causes genital herpes. It also causes abnormal vaginal discharge having a fishy odour with painful blisters and ulcers around the genitals.
In some cases, cancer of the vagina, cervix, uterus, or fallopian tubes can also be the cause of abnormal vaginal discharge. Therefore timely diagnosis of any abnormality in vaginal discharge is recommended.

What is the difference in vaginal discharge before and after periods?
Vaginal discharge can vary throughout the menstrual cycle due to hormonal changes. The vaginal discharge before periods is of more stretchable consistency and transparency. This results from increased estrogen levels, preparing the body for pregnancy. During periods, it is blood red during the first five days. After periods, the discharge may become thicker and cloudier. The post-menstrual discharge is a combination of cervical mucus and vaginal secretions. These variations are entirely normal and occur due to the body’s natural hormonal changes during different menstrual cycle phases. Any unusual changes or abnormalities in discharge before or after periods should be brought to a doctor’s notice for further evaluation.
When to seek treatment for vaginal discharge?
You must seek medical treatment if there is excessive vaginal discharge accompanied by a foul odour or unusual colour, predominantly dark yellow, grey, or green. Also, you should report to a doctor if your symptoms get worse or persist over a week. Additionally, you should be cautious if there is persistent itching, soreness, swelling, pain during urination, or discomfort during sex. If you experience fever or pain in your pelvis or belly area along with the symptoms mentioned above, it is advisable to see a doctor. Prompt medical attention ensures timely diagnosis and appropriate treatment for any underlying infections.
