Introduction

In general, itching in the genital area accompanied by yellowish-green discharge during the late stages of pregnancy may be caused by various factors such as hormonal changes, local irritation, bacterial vaginosis, trichomoniasis, or cervicitis. During pregnancy, hormonal fluctuations can lead to increased vaginal discharge and changes in vaginal pH, which may result in itching and abnormal discharge color.

In general, itching in the lower genital area accompanied by yellowish-green discharge during late pregnancy may be caused by various factors such as hormonal changes, local irritation, bacterial vaginosis, trichomoniasis, or cervicitis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified healthcare provider. The specific analysis is as follows:

1. Hormonal Changes

During pregnancy, fluctuations in hormone levels can lead to increased vaginal discharge, altering the vaginal environment and making it more conducive to bacterial growth, which may result in itching and abnormal discharge color. Maintain cleanliness and dryness of the external genital area and wear cotton, breathable underwear.

2. Local Irritation

In late pregnancy, the enlarged uterus may compress the bladder and rectum, increasing local irritation to the vulva and causing itching. Choose loose, comfortable underwear and avoid tight pants or synthetic fiber materials.

3. Bacterial Vaginosis

Bacterial vaginosis results from an imbalance of the normal vaginal flora. Pathogenic bacteria produce excessive discharge during proliferation, which mixes with shed vaginal cells and white blood cells to form yellowish-green discharge. This is often accompanied by itching, a fishy odor, redness, and swelling at the vaginal opening. Treatment may include medications such as clindamycin hydrochloride gel, ampicillin capsules, or azithromycin tablets, as prescribed by a doctor.

4. Trichomoniasis (Trichomonas Vaginitis)

Trichomoniasis is caused by infection with Trichomonas vaginalis. After damage to the vaginal mucosa, large amounts of exudate are secreted, mixing with epithelial cells, white blood cells, the parasites themselves, and their metabolic products, resulting in yellowish-green discharge and itching. Symptoms may also include pain during intercourse and urethral discomfort. Medications such as metronidazole tablets, tinidazole tablets, or clarithromycin capsules should be used under the supervision of a healthcare professional.

5. Cervicitis

Cervicitis is primarily caused by pathogen infection. Under inflammatory effects, cervical mucosa becomes congested and edematous, leading to increased exudate that mixes with mucus secreted by cervical glands, resulting in yellowish-green discharge and itching. Other symptoms may include pelvic pressure, postcoital bleeding, and discomfort. Symptom relief may involve medications such as moxifloxacin hydrochloride tablets, cefixime tablets, or Gynecological Qianjin tablets, used under medical guidance.

In daily life, maintain a regular routine, avoid excessive fatigue, and consume plenty of fruits and vegetables.
