The labia are located on the vulva, which is the exterior part of a woman’s genitals. They protect the clitoris, vagina, and urethra from infection and damage. A variety of conditions can cause swollen labia, including infections and cysts.
The labia are sometimes called the vaginal lips. There are two pairs of labia — the labia majora, located on the outside of the vagina, and labia minora, which are the inner folds of skin that lead to the vagina.
Read on to learn more about swollen labia and what can be done to prevent or treat this issue.
In addition to the swollen labia, the following symptoms may suggest an infection or another underlying medical problem:
- a feeling of hotness around the genital area
- bump on the labia
- strong or foul odor from the vagina
- unusual vaginal discharge
Common causes of swollen labia include:
The majority of women — almost 75 percent — will experience a yeast infection at least once in their lives.
Symptoms of a yeast infection include:
- white discharge that may be thick and lumpy
Conditions that increase the risk of a yeast infection include pregnancy, uncontrolled diabetes, and having a weakened immune system.

Having a history of STIs or multiple sexual partners increases the risk of getting trichomoniasis.
Allergies or irritation
If no infection is present, swollen labia may have been caused by contact with an irritating product or allergen.
Substances that may trigger swelling include:
- chemicals in fabrics
- fragrances in detergents and soaps
- latex in condoms
Bartholin’s glands are located on either side of the vaginal opening. These glands can become blocked and cause swelling in and around the vagina.
While this swelling does not usually cause other symptoms, it may lead to an infection and cause pain and a buildup of pus.
Sexual intercourse without adequate lubrication — either from the vagina itself or a lubricating product — can cause friction.
This friction can damage the vaginal area and labia, leading to swelling and discomfort.
One or more of the following may be used to diagnose the cause of swollen labia:
- medical and sexual history
- complete list of symptoms
- physical examination
- vaginal or vulvar swab
- tissue sample
- urine analysis
Further tests may be used depending on the individual’s symptoms and initial test results.
Women with swollen labia should see a doctor if the swelling worsens over time or is accompanied by any of the following:
- a lump or bump on the labia
- pain that persists or is severe
- a strong smell from the vagina
- unusual vaginal discharge
The treatment for swollen labia will depend on the underlying cause. Treatment options include:
Medication and surgical intervention
Steroid creams may be beneficial for those with swelling caused by allergies or sexual intercourse.
Women with a yeast infection may need to take an over-the-counter or prescription antifungal medication, which may be applied topically or taken orally.
Swollen labia caused by bacterial infections such as bacterial vaginosis or trichomoniasis can be treated with antibiotics.
Bartholin’s cysts do not always require treatment. However, some will require antibiotics, surgical drainage, or even surgical removal.
Home remedies for swollen labia include:
- Cool compresses: Applying a cool compress to the labia can reduce swelling. This can be repeated several times a day. Cool compresses are available to purchase online.

- Apple cider vinegar: Drinking 1 to 2 tablespoons of apple cider vinegar in a glass of water up to three times daily is a popular home remedy for yeast infections. Apple cider vinegar is available to buy in supermarkets, health stores, and online.
- Garlic: A natural antifungal, garlic is often touted as a remedy for vaginal infections. Although more research is needed to determine if it is effective,
one studydid find that a vaginal cream made with garlic and thyme was as effective for yeast infections as an antifungal medication.
- Reducing sugar intake: High-sugar diets are thought to play a role in some recurrent yeast infections. Therefore, it may be helpful to avoid sugar, processed foods, and fruit juices when experiencing a yeast infection.
