Likoria (also spelled leukorrhea or leucorrhoea) is the medical term for vaginal discharge. It refers to the white or clear fluid that naturally flows from the vagina as part of the body’s self-cleaning process. Most of the time, likoria is completely normal and healthy. It becomes a concern only when the discharge changes in color, smell, or texture, which can signal an infection or other underlying condition.
What Normal Discharge Looks Like
Normal vaginal discharge is a mixture of fluids produced by the vaginal walls, glands in the cervix, and shed skin cells from inside the vagina. It’s typically clear to white, has no strong odor, and doesn’t cause itching or irritation. When examined clinically, healthy discharge has an acidic pH below 4.5, which helps keep harmful bacteria in check.
The amount and thickness of this discharge changes throughout the month because it’s driven by estrogen levels. In the days leading up to ovulation (roughly mid-cycle), estrogen peaks and the body produces thinner, more slippery mucus to help sperm travel more easily. After ovulation, the discharge often becomes thicker and stickier. Right before a period, you may notice a slight increase again. These shifts are normal and don’t require any treatment.
Why It Increases During Puberty and Pregnancy
Many girls first notice vaginal discharge around puberty, when rising estrogen levels trigger changes throughout the reproductive system. This is one of the earliest signs that the body is maturing, and it often begins a year or two before the first menstrual period.
During pregnancy, discharge increases significantly. The body produces more estrogen (particularly a form called estriol), which boosts blood flow to the vaginal area and stimulates more fluid production. Normal pregnancy discharge is thin, clear or milky white, mild in odor, and tends to increase gradually as the pregnancy progresses. Research published in the Pakistan Journal of Medical Sciences found that normal pregnancy discharge was consistently watery, left only a slight stain on clothing, and had no smell. This is the body’s way of keeping the birth canal clean and protected from infection. If the discharge becomes yellowish-green, foul-smelling, or heavy enough to soak through clothing, it could indicate an infection that needs attention, since pathological discharge during pregnancy has been linked to higher rates of premature contractions and early membrane rupture.
When Discharge Signals a Problem
Abnormal likoria differs from the healthy kind in noticeable ways. Watch for these changes:
- Color: Yellow, green, or gray discharge often points to infection. A cottage cheese-like white texture suggests a yeast infection.
- Odor: A strong, fishy, or foul smell is a hallmark of bacterial vaginosis or other infections. Normal discharge has little to no odor.
- Texture: Frothy or chunky discharge is not typical. Frothy, greenish-yellow discharge is a classic sign of trichomoniasis, a sexually transmitted infection caused by a parasite.
- Accompanying symptoms: Itching, burning during urination, pelvic pain, bleeding between periods, or pain during intercourse all suggest something beyond normal discharge.
The three most common infections behind abnormal discharge are bacterial vaginosis (an overgrowth of certain bacteria that naturally live in the vagina), yeast infections (caused by a fungus called Candida), and trichomoniasis. Cervical infections from gonorrhea or chlamydia can also cause unusual discharge, though these are less common.
Non-infectious causes exist too. A forgotten tampon or other foreign body, allergic reactions to soaps or detergents, and hormonal changes after menopause (which thin the vaginal walls) can all produce abnormal discharge.
How Infections Are Treated
Treatment depends entirely on the cause. Yeast infections are the most straightforward to manage. Uncomplicated cases respond well to over-the-counter antifungal creams or suppositories, typically used for one to seven days. A single-dose oral antifungal pill is also widely prescribed. For recurring yeast infections (four or more episodes per year), a longer initial course of treatment followed by weekly oral medication for up to six months may be needed to keep the infection from returning.
Bacterial vaginosis and trichomoniasis require prescription antibiotics, usually taken orally. These infections won’t clear up on their own, and leaving them untreated raises the risk of more serious complications.
What Happens if You Ignore It
Left untreated, certain infections that cause abnormal discharge can spread from the vagina and cervix upward into the uterus and fallopian tubes, leading to pelvic inflammatory disease (PID). PID causes scar tissue and pockets of infection in the reproductive tract. The consequences can be severe: chronic pelvic pain, difficulty getting pregnant, and increased risk of ectopic pregnancy, where a fertilized egg implants in the fallopian tube instead of the uterus. Ectopic pregnancies can cause life-threatening bleeding. The risk of infertility increases with each episode of PID, and delaying treatment makes the damage worse.
This is why persistent changes in discharge, especially when paired with fever, lower abdominal pain, or pain during a pelvic exam, need prompt evaluation.
Daily Habits That Support Vaginal Health
The vagina is self-cleaning, so internal washing (douching) does more harm than good by disrupting the natural balance of protective bacteria. International gynecological guidelines recommend gentle daily cleansing of the external vulva only, using a mild, hypoallergenic wash or plain water. This removes the normal buildup of sweat, discharge, and bacteria without interfering with the vagina’s internal environment.
A few other practical steps help maintain healthy discharge levels. Wearing breathable cotton underwear reduces moisture buildup that encourages yeast growth. Changing out of wet swimsuits or sweaty workout clothes promptly matters for the same reason. Avoiding scented pads, tampons, sprays, and soaps in the genital area reduces the chance of irritation and allergic reactions that mimic infection symptoms. If you’re on antibiotics for another condition, be aware that they can disrupt vaginal bacteria and temporarily increase your risk of a yeast infection.
Normal likoria is a sign that the reproductive system is functioning as it should. Paying attention to what’s typical for your body makes it much easier to spot when something has genuinely changed.
