Vaginitis is the term doctors use when the vagina becomes inflamed or infected. This irritation can cause discomfort, itching, burning, unusual vaginal discharge or pain. In many cases the inflammation also spreads to the vulva, the outer area of the female genitals. That's why the condition is sometimes also called vulvovaginitis.

The vagina naturally has a balance of bacteria and yeast. Good bacteria (lactobacilli) keep the vaginal environment slightly acidic, which helps prevent infections. When this balance is disturbed due to infection, hormonal changes or external irritants, vaginitis develops.

Vaginitis can happen at any age:

• Vaginitis in children: Usually caused by poor hygiene, pinworms or irritation from soaps.
• Reproductive-age women: Most common often linked to bacterial vaginosis, yeast infections or sexually transmitted infections.
• Vaginitis during pregnancy: Hormonal changes and increased vaginal discharge raise the risk of infections.
• Vaginitis after menopause: Lower estrogen levels can cause vaginal dryness and lead to atrophic vaginitis.

In simple terms, vaginitis is not one single disease but a group of conditions that affect the vagina and vulva in similar ways. Each type has its own causes and requires different treatment.

Vaginitis Types

Vaginitis can occur for different reasons and doctors usually classify it into several main types. Each type has its own causes, symptoms and management approach:

Bacterial Vaginosis (BV)

This is the most common type of vaginitis, especially in women of reproductive age. It happens when the healthy bacteria in the vagina are outnumbered by harmful bacteria. Women with BV often notice a thin, greyish-white discharge and a strong fishy odor, particularly after sex. Doctors usually treat BV with prescribed antibiotics such as metronidazole or clindamycin.

Vaginal Yeast Infection (Candidiasis)

A yeast infection occurs when the natural fungus Candida grows excessively. It often develops after antibiotic use, during pregnancy or in women with diabetes.

Common signs include intense vaginal itching, redness, burning and a thick white discharge that looks like cottage cheese. Antifungal medicines, available as oral tablets or vaginal creams, are commonly used to treat it.

Trichomoniasis

Trichomoniasis is a sexually transmitted infection caused by a tiny parasite. Some women may not have symptoms but others develop frothy yellow-green discharge, a strong odor, vaginal burning or pain during sex.

This infection requires prescription medicine and both partners usually need treatment to prevent reinfection.

Atrophic Vaginitis (Vaginal Atrophy)

Atrophic vaginitis usually affects women after menopause when estrogen levels drop. Lower estrogen makes the vaginal tissues thinner, drier and less elastic. This can cause irritation, burning, and pain during sex.

Doctors may recommend vaginal moisturizers, lubricants or hormone-based medicines to improve comfort.

Irritant or Allergic Vaginitis

Sometimes vaginitis is not due to infection but rather a reaction to soaps, scented products, douches or latex condoms. This type leads to burning, redness and watery discharge. Avoiding the irritant usually helps and a doctor may suggest soothing creams if symptoms persist.

Each type of vaginitis may look similar, but the cause and treatment are different. This is why it's important to get the right diagnosis instead of self-treating based only on symptoms.

Vaginitis Symptoms

The symptoms of vaginitis can vary depending on the cause but many women notice similar changes. Some women may only have mild discomfort, while others experience more intense irritation.

Here are the most common vaginitis symptoms:

Vaginal Itching

One of the earliest and most bothersome signs of vaginitis is constant itching in or around the vagina. This can become worse at night or after urination.

Vaginal Burning

A burning sensation is another frequent complaint. Many women feel this while urinating or during sexual intercourse which can interfere with daily life and intimacy.

Vaginal Discharge

Changes in discharge are very common. It may:

• Become thicker or clumpy, like cottage cheese, which is typical of a yeast infection.
• Turn thin and greyish with a strong fishy odor common in bacterial vaginosis.
• Look frothy, greenish or yellow with a foul smell seen in trichomoniasis.

Unpleasant Odor

Some women notice a strong or fishy smell, especially after sex. This is a classic sign of bacterial vaginosis.

Redness and Swelling

The vagina and vulva may look red, swollen and inflamed, making it uncomfortable to sit, walk, or exercise.

Pain or Discomfort During Sex

This is especially common in atrophic vaginitis, where thinning and dryness of vaginal tissues cause painful intercourse.

Spotting or Light Bleeding

In some cases, women may notice light bleeding between periods, especially with atrophic vaginitis.

These symptoms can overlap between different types of vaginitis, which makes self-diagnosis tricky.

Vaginitis Causes

Vaginitis develops when the natural balance of the vagina is disturbed. Normally, the vagina has a mix of bacteria and yeast that keep it healthy and slightly acidic. When something upsets this balance, harmful organisms can grow and cause irritation, discharge and discomfort.

Here are the main causes of vaginitis:

Bacterial Imbalance

The main cause of vaginitis is bacterial vaginosis (BV). It happens when the healthy bacteria (lactobacilli) decrease and harmful bacteria grow in large numbers. This imbalance leads to thin discharge and a fishy odor.

Yeast Overgrowth

A vaginal yeast infection occurs when the fungus Candida multiplies more than usual. Antibiotic use, high blood sugar, pregnancy or a weak immune system can increase the risk of yeast overgrowth.

Sexually Transmitted Infections (STIs)

Trichomoniasis is an infection caused by a tiny parasite that spreads through unprotected sex. It may cause a yellow-green discharge, itching and a burning sensation.

Hormonal Changes

Pregnancy brings hormonal changes that can increase the risk of infections. After menopause, lower estrogen levels can lead to dryness, burning and irritation in the vaginal area.

Irritants and Allergens

Certain products can irritate the vaginal area and trigger inflammation. These include:

• Scented soaps, sprays, or bubble baths
• Douches and feminine hygiene products
• Laundry detergents or fabric softeners
• Latex in condoms or spermicides

Poor Hygiene or External Factors

Not changing damp clothing quickly, wearing tight non-breathable underwear or wiping from back to front after using the toilet can allow bacteria to spread and increase the risk of infection.

Vaginitis causes can range from infections and hormonal changes to everyday habits and irritants. Identifying the exact reason is the first step toward proper vaginitis treatment.

When to See a Doctor for Vaginitis?

Many women experience occasional vaginal discomfort, but not all cases of itching or discharge mean vaginitis. However, certain warning signs mean it's best to seek professional medical help.

You should see a doctor if you have:

• Symptoms are severe or interfere with daily activities.
• Vaginal itching, burning, or unusual discharge persists.
• There is a strong, unpleasant odor.
• Pain occurs during urination or sex.
• Vaginitis occurs during pregnancy.
• Infections keep recurring or do not improve.
• There is unexpected bleeding, pelvic pain, or fever.

If your symptoms are new, severe, recurring or happening during pregnancy, it's best to see a healthcare professional rather than rely on self-treatment.

Diagnosis of Vaginitis

Correct diagnosis is crucial because the treatment for vaginitis depends on its cause. Since different types of vaginitis can have similar symptoms, doctors use a combination of history, examination and tests to determine the exact cause.

Medical History

Your doctor will ask questions about:

• Symptoms: Itching, burning, discharge, odor, pain.
• Sexual history: New or multiple partners, condom use.
• Recent antibiotic use or other medications.
• Hormonal changes: Pregnancy, menopause or contraceptive use.

This helps the doctor narrow down possible causes before tests.

Physical Examination

A gynecological exam allows the doctor to check for:

• Redness, swelling or irritation in the vagina and vulva
• The color, texture and amount of vaginal discharge
• Signs of irritation or injury

Laboratory Tests

Sometimes, a swab of the vaginal discharge is taken for analysis. Tests may include:

• Microscopic examination (wet mount): Detects bacteria, yeast or parasites.
• pH testing: Measures vaginal acidity abnormal pH can indicate bacterial vaginosis or trichomoniasis.
• Culture tests: Grow organisms in a lab to identify the exact cause if the infection is persistent.

These tests help distinguish between bacterial vaginosis, yeast infections, trichomoniasis and other conditions.

Additional Tests

In some cases, your doctor may order:

• STI screening like chlamydia, gonorrhea, HIV if sexual transmission is suspected
• Hormone tests if atrophic vaginitis is suspected due to menopause

Accurate diagnosis ensures that you receive the right vaginitis treatment, rather than guessing with over-the-counter remedies. This reduces the risk of persistent infection and recurrence.

Vaginitis Treatment

Treatment for vaginitis depends on the type of infection or cause. Understanding the type helps doctors choose the right medicine and plan.

Treatment for Bacterial Vaginosis (BV)

BV is usually treated with prescription antibiotics such as metronidazole or clindamycin, either as a pill or vaginal gel. Completing the full course is essential even if symptoms improve quickly. Doctors may also recommend avoiding douching or scented products during treatment to prevent recurrence.

Treatment for Vaginal Yeast Infection (Candidiasis)

Yeast infections are treated with antifungal medicines such as:

• Vaginal creams or suppositories
• Oral antifungal tablets
• These treatments reduce vaginal itching, burning and thick white discharge. Non-prescription creams can be used for mild infections but recurrent infections may require a doctor's prescription.

Trichomoniasis Treatment

This sexually transmitted infection requires oral antibiotic treatment, usually metronidazole or tinidazole. Both sexual partners need treatment to prevent reinfection. Symptoms often improve quickly after completing the course.

Atrophic Vaginitis (Vaginal Atrophy) Treatment

Common after menopause, atrophic vaginitis is treated with vaginal moisturizers, lubricants or estrogen-based medicines. These help reduce dryness, burning and painful intercourse. Low-dose local estrogen therapy is often recommended under medical supervision.

Treatments for Irritant or Allergic Vaginitis

This type is caused by chemical or product irritation. Treatment involves:

• Avoiding the irritants like soaps, scented products, douches and latex condoms.
• Using soothing creams if needed
• Maintaining proper hygiene and wearing breathable cotton underwear

Home Remedies and Lifestyle Measures for Vaginitis Problems

Certain practices can relieve symptoms and prevent recurrence:

• Avoid scented soaps, douches and feminine sprays
• Keep the genital area clean with plain water
• Wear breathable cotton underwear and change damp clothing promptly
• Maintain healthy blood sugar if diabetic
• While helpful, these measures do not replace medical treatment for infections.

Vaginitis Treatment During Pregnancy

Pregnant women need special care. Some medicines safe for non-pregnant women may not be safe during pregnancy. Always consult an OB-GYN before using any vaginitis cream or medicine. Treating infections immediately during pregnancy is important to reduce the risk of complications.
