Why does it feel like bubbles are coming out from the vagina during pregnancy, and what should I do about it?

　　A bubbling sensation during pregnancy may be caused by increased vaginal discharge, pelvic floor muscle relaxation, bacterial vaginosis, fungal vaginitis (yeast infection), or trichomoniasis. Symptoms can be improved through proper hygiene, exercises, or medical treatment. Seek prompt medical attention if accompanied by itching, unusual odor, or abnormal discharge.

　　1. Increased vaginal discharge: Hormonal changes during pregnancy can lead to more vaginal discharge. The movement of this discharge may create a bubbling sensation, usually without odor. It is recommended to wash the external genital area daily with warm water, change cotton underwear frequently, and keep the genital area dry and clean.

　　2. Pelvic floor muscle relaxation: As the uterus enlarges during pregnancy, it puts pressure on the pelvic floor muscles, causing them to loosen. This allows air to enter the vagina, which may produce a bubbling sensation when released. It is advised to perform Kegel exercises under medical guidance to strengthen the pelvic floor muscles, and avoid prolonged standing or squatting.

　　3. Bacterial vaginosis: An imbalance in vaginal flora leads to overgrowth of harmful bacteria, causing inflammation. This results in increased foamy discharge with a fishy odor. Treatment may include medications such as metronidazole vaginal suppositories, clindamycin cream, or nitrofurantoin-nystatin vaginal soft capsules, used under a doctor’s guidance.

　　4. Fungal vaginitis (yeast infection): Reduced immunity during pregnancy allows Candida (a type of fungus) to overgrow, leading to inflammation. Discharge appears curd-like, sometimes accompanied by frothiness and itching. Treatments may include clotrimazole suppositories, miconazole nitrate suppositories, or nystatin suppositories, used as directed by a healthcare provider.

　　5. Trichomoniasis: Infection caused by the parasite *Trichomonas vaginalis* leads to inflammation, producing yellow-green foamy discharge along with itching and odor. Follow medical advice to use medications such as metronidazole vaginal effervescent tablets, tinidazole suppositories, or oral metronidazole tablets to relieve symptoms.

　　For daily care, choose loose-fitting, breathable cotton underwear, change and wash them regularly, clean the external genital area with warm water, avoid overusing feminine washes, attend regular prenatal checkups, and monitor both maternal and fetal health.
