Greenish Discharge in Women: Possible Causes

You noticed discharge with a greenish tint on your underwear — and you are probably already looking for an explanation. Let's calmly sort out what is considered normal, what causes green and yellow-green discharge can have, and when a gynecologist consultation is needed.

Which discharge is considered normal and which is not

Vaginal discharge is a mixture of cervical mucus, fluid from the vaginal walls, shed cells, and bacteria. It lubricates and protects the vagina, so its presence is a sign that the body is working normally. Normal discharge is clear, white, or yellowish, thin or thick and sticky, with a faint odor or no odor. On average, a healthy woman of reproductive age has about 1.5 grams of discharge per day, roughly half a teaspoon.

The amount and consistency change throughout the cycle: in the first days after menstruation there is little discharge and it is thick; as ovulation approaches, there is more of it, and it is clearer and more elastic. The volume increases during pregnancy, with sexual activity, and when using contraception. A warning sign is a change in odor, color, or texture, as well as itching and pain.

Green and yellow-green discharge: what they may mean

Green and yellow-green color is considered a sign of abnormal discharge — along with changes in amount, consistency, and the appearance of odor. This shade may be a sign of infection, and the doctor's task is to determine which one. After puberty, the environment in the vagina is acidic, pH approximately 3.5–4.7, and lactobacilli predominate in it — around 10⁸–10⁹ bacteria per milliliter of discharge.

Foamy and greenish discharge: possible causes

Green, yellow, or foamy discharge may be a sign of trichomoniasis. With bacterial vaginosis, discharge is usually gray, with a fishy odor; with a yeast infection, it is thick and white, resembling cottage cheese. If green or yellow discharge occurs together with pelvic pain or bloody discharge, chlamydia and gonorrhea are considered, and if there are blisters or sores — herpes.

There are also non-infectious causes: a forgotten tampon or another foreign body (an unpleasant odor appears), irritation from soap, gels, laundry detergents, scented pads and sprays, contraceptive creams. Less commonly — low estrogen levels after menopause, some skin diseases, and, in rare cases, tumors of the female reproductive system.

Greenish discharge without odor or pain: what this may indicate

The absence of odor, itching, and pain is good news, but not a guarantee of normality. Discharge is considered abnormal when its amount, color, consistency, or odor have changed, and a greenish tint is on this list. Strong odor and itching often accompany infection, but their absence does not rule it out. It is impossible to distinguish normal from infection by appearance; this is assessed by a doctor.

How the doctor determines the cause of discharge

The gynecologist asks about symptoms and medical history, then performs an examination, including a pelvic exam. Further tests may include: culture of discharge from the cervix, microscopic examination of discharge, a Pap smear, and, if necessary, a vulvar skin biopsy. The set of tests depends on what is seen during the examination. A diagnosis is not made from an internet photo.

When to see a gynecologist

Any change in the nature of discharge is a reason to make an appointment, as well as:

• discharge has changed color, odor, or texture;
• there is noticeably more of it than usual;
• itching, irritation, redness, or soreness has appeared;
• there is bloody discharge between periods or after sex;
• there is pain when urinating or pelvic pain.

Seek help without delay — with fever and pelvic or abdominal pain, with blisters and sores on the skin of the vulva and vagina, if symptoms worsen or last longer than a week, and also after suspected contact with a sexually transmitted infection.

Greenish discharge by itself is not a reason to call an ambulance. 103 or 112 — for loss of consciousness, severe bleeding, or another life-threatening condition.
