What causes increased vaginal discharge at 37 weeks of pregnancy?

Generally speaking, increased vaginal discharge at 37 weeks of pregnancy is mainly caused by hormonal changes, cervical ripening, elevated estrogen levels, amniotic fluid leakage, or vulvovaginal candidiasis. If you experience any discomfort, please seek medical attention promptly. Detailed explanations are as follows:

1. Hormonal Changes

During pregnancy, especially near term, elevated estrogen levels stimulate increased mucus secretion in the vagina and cervix, leading to increased vaginal discharge. No specific treatment is required. Maintain good personal hygiene, change underwear and sanitary pads regularly, and keep the vulva clean and dry.

2. Cervical Ripening

As pregnancy progresses, the cervix gradually softens and dilates, which can lead to increased vaginal discharge. No specific treatment is needed, but regular prenatal checkups are important to monitor cervical changes.

3. Elevated Estrogen Levels

During pregnancy, estrogen levels rise, which can increase secretions from the vagina and cervix, resulting in increased vaginal discharge. No specific treatment is necessary; maintaining cleanliness of the vulva is sufficient.

4. Amniotic Fluid Leakage

In late pregnancy, small amounts of amniotic fluid may leak due to gaps between the fetal membranes and cervix or minor membrane ruptures, presenting as increased vaginal discharge, although the volume is usually minimal. If the leakage is minimal and the fetal condition is stable, continued observation is acceptable. If the situation is severe, seek immediate medical attention. Change underwear daily and expose it to sunlight for disinfection purposes.

5. Vulvovaginal Candidiasis

This condition is commonly caused by Candida species. Immune function declines during pregnancy, making women more susceptible to infection. Symptoms include increased vaginal discharge that is thick in consistency, possibly with a yellowish color and accompanied by itching. Patients can use medications such as fluconazole capsules, itraconazole capsules, or metronidazole-clotrimazole suppositories under the guidance of a qualified physician.

It is recommended to enhance nutrition by consuming more fruits and vegetables while limiting spicy and irritating foods, which not only helps prevent increased vaginal discharge but also benefits the baby's health.
