Vaginal infections are very common. Vaginal infections result in vaginitis (swelling of the vagina).
Signs, Symptoms & Causes
Bacterial Vaginosis (BV)
Most females with clinical signs of BV report no symptoms. When present, symptoms include:
- A thin, gray, or milky white vaginal discharge. This has a fishy odor, which is more noted after intercourse.
- Itching around the outside of the vagina.
- Mild vaginal irritation or burning.
Bacterial vaginosis results when certain bacteria outnumber normal and protective bacteria in the vagina. The exact cause is not known.
Risk factors for BV include douching, using an IUD, and a change or an increase in sexual partners.
Vaginal Yeast Infections
Vaginal yeast infections are also called Monilia, Candida, and fungal infections. Signs and symptoms range from mild to severe. They include:
- Thick, white vaginal discharge that looks like cottage cheese and may smell like yeast.
- Itching, irritation, swelling and redness around the vagina.
- Burning and/or pain when urinating or with sex.
Vaginal yeast infections result from the overgrowth of the fungus Candida. This is normally present in harmless amounts in the vagina, digestive tract, and mouth.
Risk Factors
Vaginal Yeast Infections
- Hormonal changes that come with pregnancy or monthly periods, and taking hormones or birth control pills.
- Antibiotic use, especially “broad spectrum” ones. Corticosteroid medicine use.
- High blood sugar, which can occur when diabetes is not controlled.
- Sex that irritates the vagina a lot.
- Using douches and feminine hygiene sprays.
- Using hot tubs and jacuzzis frequently.
Chronic vaginal yeast infections can be one of the first signs of diabetes, STIs and HIV.
Diagnosis
Different vaginal infections have the same symptoms. This makes it hard to tell one from another. A doctor may need to diagnose the cause. A sample of vaginal fluid is taken and tested. Often, this takes less than 3 minutes.
