Last Updated: 13/09/2022

Clear discharge and vagina (clear leucorrhoea) is a watery or mucous colorless discharge from the genital tract, often without any unpleasant odor. Sometimes accompanied by itching in the perineum, discomfort during intercourse. The symptom occurs due to natural hormonal changes, it is also provoked by stress, allergic reactions, and helminthiases. To establish the cause that caused the transparent discharge, a gynecological examination, colposcopy, and laboratory tests are performed. Medications are used in the presence of diseases of the reproductive system.

Causes of clear vaginal discharge

Physiological hormonal changes

Normally, the amount of vaginal secretion increases as you approach ovulation, which is due to the action of the hormone estrogen. The leucorrhea is odorless, the consistency is rather thick, mucous, in appearance they resemble "viscous snot" or egg white. For several days after ovulation, watery, clear vaginal discharge may disturb. The secret is insignificant in volume, more often patients notice stains on their underwear or a small amount of mucus on a daily pad. The symptom is not accompanied by itching, the general state of health remains good.

At puberty, the appearance of a transparent, odorless vaginal discharge is caused by sharp jumps in estrogen during the formation of the menstrual cycle, the effect of other hormones and active substances on the secretion of the cervical glands. Adolescent girls may complain of abundant clear leucorrhoea (“like water”) observed on different days of the cycle. With cloudy mucous secretions with a sour smell, itching in the vulva, discomfort in the lower abdomen, you should consult a specialist.

stressful situations

A common cause of odorless watery discharge is chronic stress, overwork at work, and a sudden change in climate. All these situations have an adverse effect on the hormonal background, which leads to a violation of the secretory function of the glands of the vestibule of the vagina and cervix. The disorder is typical for young emotional girls. Often, transparent vaginal discharge is combined with a decrease in sexual desire, general weakness and deterioration in performance. If the symptom persists for a long time, you should visit the office of an obstetrician-gynecologist.

allergic inflammation

With this type of inflammatory reaction, the vaginal discharge is very liquid, transparent. In the acute phase of allergy, the discharge is abundant, accompanied by intense itching in the vagina and perineum. Many women note the connection of the symptom with the use of intimate hygiene products, wearing synthetic underwear. These factors provoke allergic colpitis (vaginitis). If a clear, odorless discharge is observed after intercourse, this may be due to an allergy to latex or polyurethane in barrier contraceptives.

 

Viral sexual infections

Transparent watery discharge from the genital tract may be accompanied by infections of viral origin, transmitted through sexual contact. The most common infections are the herpes simplex virus and human papillomavirus. In this case, women can be affected by the perineum and vulva, urethra, rectum, vagina, cervical canal, and with advanced herpes, the bladder, uterus and fallopian tubes.

  • Genital herpes. In the initial period, bubble rashes are filled with transparent exudate. Their appearance is accompanied by unbearable painful itching and a burning sensation in the affected area. When the vesicles open, fluid flows out, which causes a feeling of constant moisture in the intimate area. Gradually, the serous contents of the vesicles change to cloudy, purulent or hemorrhagic, so the nature of the discharge also changes. Among the general symptoms, weakness, muscle pain, a temperature jump, and an increase in lymph nodes in the groin are noted.
  • Genital warts. They are single nodules or multiple growths in the form of a “cockscomb” or “cauliflower” of a pale pink or grayish color. Accompanied by itching and paresthesia, clear watery discharge from the vagina, weeping of the skin and mucous membranes. Condylomas of the anogenital region are prone to injury during scratching, sexual intercourse, so some women note bloody discharge from the vagina.

Helminthiases

Parasitic invasions are more typical for young girls, which is facilitated by non-compliance with hygiene standards and an alkaline environment in the vagina, which facilitates the attachment and reproduction of helminths. With helminthiases, thickish mucous secretions (like egg white) are noted, usually odorless. Girls complain of itching of the perineum and anal area, white worm larvae are found on the underwear fabric. With prolonged vaginal helminthiasis, transparent mucous discharge with a rotten odor is possible, blood streaks are sometimes noticeable in the mucus.

Rare Causes

  • Endocrine diseases : hypothyroidism, insufficiency of the adrenal cortex.
  • Avitaminosis A and E.
  • Decreased immunity : with prolonged viral or bacterial infections, chronic diseases.

Diagnostics

If transparent discharge from the vagina is detected, a consultation with a gynecologist is required to exclude the pathological prerequisites for the condition. Diagnostic search involves a comprehensive study of the genital tract mucosa, an assessment of the hormonal background, and the identification of concomitant pathology. Patients are prescribed instrumental and laboratory methods, the most informative of which are:

  • Gynecological examination. During a visual examination of the vagina, cervix in the mirrors, attention is paid to the condition of the mucous membrane, the presence of areas of hyperemia or erosion. Adolescent girls undergo a rectal examination and palpation of the uterus through the anterior abdominal wall. Be sure to take a vaginal smear for microflora.
  • Instrumental inspection . For a detailed study of the epithelium of the cervix, an extended colposcopy is used, which includes testing with acetic acid and Lugol's solution to exclude precancerous conditions. To clarify the cause of mucous secretions with a specific odor, hysteroscopy, hysterosalpingography are additionally used.
  • Laboratory diagnostics . To identify pathogenic microbes and signs of dysbiosis, an analysis is performed on the microflora of the vagina. Microscopy of a vaginal smear can reveal helminth eggs. Transparent discharge without a noticeable odor that occurs at different periods of the menstrual cycle is an indication for determining the levels of estrogen and progesterone. Viral pathogens are detected by PCR methods.

When vaginal discharge is combined with discomfort and pain in the lower abdomen, ultrasound of the pelvic organs is recommended to exclude diseases of the uterus or appendages. To confirm the allergic origin of the discharge from the genitals during the period of exacerbation of the disease, an immunogram is performed, after the relief of symptoms - allergy tests. In case of difficulties in diagnosis, they resort to consultations of other specialists.

Treatment

Help before diagnosis

Clear vaginal discharge that occurs during or before ovulation does not require specific treatment. Women are advised to comply with hygiene standards, use daily pads. It is advisable to reduce the number of cosmetic products used for intimate hygiene so as not to cause irritation of the reproductive organs or allergies. If you change the color or consistency of the discharge, the appearance of an unpleasant odor in the discharge, you should contact a gynecologist to find out the cause of the disorder.

Conservative therapy

If the patient has an inflammatory process in the genital organs or extragenital pathology, the treatment regimen is selected individually. Systemic drug therapy is supplemented by local effects: baths with antiseptics and medicinal herbal decoctions are shown, vaginal suppositories with lactobacilli are used to restore the vaginal microflora. Of the drugs most often used:

  • Anthelmintics . Selectively act on pathogens of helminthic invasions at different stages of the life cycle. Medicines are combined with vaginal antiseptics in the form of suppositories to quickly eliminate the cause of the discharge.
  • Antiviral drugs . It is prescribed for confirmed viral etiology of clear discharge. Drugs with antiviral activity are used, both local (in the form of cream, ointments, vaginal suppositories) and systemic action (tablets, injections). The basic means are acyclovir, interferon. For preventive purposes, women are advised to vaccinate against herpes and HPV before sexual debut.
  • Antihistamines . Effectively relieve itching and discomfort in allergic vaginitis, reduce the amount of discharge. In severe systemic allergies, short-term administration of corticosteroid tablets is indicated.
  • Vitamins . Retinol (vitamin A) improves the condition of the epithelial layer of the genital tract, eliminates irritation and itching. Alpha-tocopherol is prescribed to normalize hormonal levels, increase progesterone levels in the second phase of the cycle.
  • Destruction of warts . Various methods are used to remove genital warts: cryosurgery, laser coagulation, chemical destruction, radio wave surgery, etc. Combined therapy, which involves a combination of a destructive method and antiviral therapy, significantly reduces the percentage of relapses of genital warts.

The key condition for complete recovery in diseases during which transparent leucorrhoea is released is the prescribed treatment under the supervision of a gynecologist until the symptoms disappear completely. Subsequently, a preventive examination by a specialist every six months, sufficient rest, a diet rich in vegetables and fruits or taking vitamin complexes, avoiding contact with allergens, careful observance of intimate hygiene, and the use of barrier contraception are recommended.
