Vaginal discharge can be defined as the fluid or mucus that is released naturally from the vagina and it performs several physiologically important functions in the body. It is produced by glands that are scattered and distributed in and around the vagina and cervix. Thus this fluid is functionally contributing to the maintenance of health and hygiene in the area. Vaginal discharge lubricates the vagina thereby avoiding dryness that causes discomfort or irritation. It also helps to flush out non-living cells and other debris from the vaginal walls to promote a healthy clean environment. The main functions of vaginal discharge include preventing infection by washing away pathogenic bacteria and maintaining a balanced environment within the vagina. The discharge also contains antimicrobial agents that protect the body from infection upon penetration. Apart from cleaning, this secretion makes the pH level of the vagina slightly acidic and helps prevent unwanted growth of bad bacteria or yeast.
The nature of vaginal discharge depends on various factors such as one's hormones, their age, the stage of their menstrual cycle, pregnancy, sexual activity and overall health. In the majority of cases, vaginal discharge is either clear or white with a slight odor or none at all. Generally, it ranges from watery to quite thick and more viscous. The texture varies according to the menstrual cycle. In the early and late stages, the discharge may be more "watery" and "abundant", while in the middle of the cycle - mostly after ovulation - it becomes "thick and creamy". At the time of ovulation, cervical mucus should be clear, slippery and slightly stretchy, similar to the texture of raw egg whites. This change in consistency is the body's signal that pregnancy is indeed likely to occur.
While it is usually harmless, sometimes a change in the characteristics of vaginal discharge, such as color, consistency or odor, can indicate that something is wrong with a person's health. Yellow or green discharge, especially if it has an unpleasant odor associated with it, may be a sign of an infection such as bacterial vaginosis or a sexually transmitted disease that may include gonorrhea or chlamydia. "Also thick, white and sticky discharge may be an indicator of a yeast infection caused by an overgrowth of a fungus called Candida." Brown or blood-tinged discharge, especially occurring outside of the menstrual cycle, may indicate an underlying condition in the uterus, such as polyps, fibroids, or even some malignancies.
Physical factors govern vaginal discharge, the menstrual cycle being perhaps the most important. The female body is hormonal during the phases it goes through in the cycle, and under known conditions, the consistency and amount of vaginal discharge changes. Immediately after bleeding, it is often scanty and clear, before becoming abundant and bicolored as ovulation draws closer. At the time of ovulation, the consistency of the discharge is considered fertile, which indicates that it resembles raw egg whites, creating a favorable environment for sperm to travel through the cervix for fertilization. After ovulation, the discharge thickens, and as the body prepares for menstruation, it may appear creamy.
Pregnancy is also associated with changes in vaginal discharge. Pregnant women usually experience more discharge due to hormone changes, which are also accompanied by increased blood flow to the pelvic region. Mostly thick, white and without any foul odor, such discharge is known as leucorrhoea, and its purpose is to protect pregnancy by preventing infection in the vagina and cervix. Similarly, one of the effects of contraceptive methods, such as hormonal birth control, causes changes in vaginal discharge, either increasing or decreasing its amount depending on the contraceptive used.
Certain health problems such as sexually transmitted infections (STIs), yeast infections, or bacterial vaginosis can result in abnormal changes in vaginal discharge. For example, if a woman notices a significant difference in the color, consistency, or odor of her discharge, she needs to see a healthcare provider regarding that change, whether it is due to an infection or a health concern. An example of a condition that can cause discharge with varying colors (most often green or brown) and often an unpleasant odor is bacterial vaginosis or trichomoniasis. Predictably, yeast infections are characterized by thick discharge that is white and sticky and usually comes with itching and discomfort.
It is important to say that there are other contributing factors besides infection: stress, diet, hydration, and lifestyle affect individual vaginal discharge. In a person’s life, the level of stress can affect the hormonal balance in such a way that it alters the quality of the discharge. Diet and hydration largely affect the state of the body’s secretions; For example, dehydration can cause the secretions to thicken and reduce in volume. A balanced diet rich in vitamins and minerals will do wonders and also include water intake to maintain healthy secretions.
Many times changes in vaginal discharge symbolize an environmental response; for example, it is changing weather, different personal care products, or sexual activity behavior. As an example, after sexual activity in healthy women, discharge typically increases and may also change in texture and consistency. Also, hormonal contraceptive methods such as the oral contraceptive pill may cause changes in vaginal discharge with increased or decreased production. Knowing one's normal discharge pattern is also important to understand when there is a change that causes a medical health concern.
There may be variations in vaginal discharge that are harmless which may possibly be part of the normal functioning of the body, but any factors affecting discharge such as color, consistency, and odor may indicate a serious condition, especially if associated with symptoms such as pain, itching, or burning. Changes that continue or changes that are a bit strange may indicate an infection or some other health issue that will need attention. Various tests, including a pelvic exam, pap smear, or culture test, may be performed by a healthcare provider to determine the cause of abnormal discharge and provide necessary treatment if needed.
Vaginal discharge is normal and important for many functions, such as lubricating the vagina, cleaning the vagina, preventing infection, and aiding in fertility. It is typically clear, white, and odorless and can change between different physical and environmental conditions during the menstrual cycle. If any abnormalities occur in vaginal discharge or additional worrisome symptoms appear, a health care provider should examine the patient to rule out possible infection or other health conditions. Gaining personal knowledge of what is normal vaginal discharge and what is typical for one's body can help understand when to take action for vaginal health and seek medical care if necessary.
