How Do I Know If I Have a Yeast Infection or Something Else?

It’s uncomfortable, it’s frustrating and it’s more common than you might think. Vaginal itching, unusual discharge, and irritation often lead people to assume they have a yeast infection, but that isn’t always the case.

While a vaginal yeast infection is a frequent culprit, other conditions can cause similar symptoms and require different treatment. Knowing what to look for and when to see your provider can help you find relief quickly and avoid unnecessary treatments.

This guide will explain what causes yeast infections, how to recognize the signs, what other conditions might be responsible, and the best ways to treat and prevent future infections.

What Is a Vaginal Yeast Infection?

A vaginal yeast infection, or vaginal candidiasis, is a common fungal infection caused by an overgrowth of a fungus called Candida albicans.

Typically, the vagina contains a healthy balance of yeast and bacteria. Healthy bacteria keep yeast levels in check. But if this balance is disrupted from antibiotics, hormone changes, or a weakened immune system too much yeast grows, leading to vaginal yeast infection and discomfort.

How Common Are Yeast Infections?

Most vaginal yeast infections are mild and easily treated. According to the Centers for Disease Control, about 75% of women will get a yeast infection at some point. Some people experience recurrent yeast infections, which can be more challenging to manage.

What Are the Symptoms of a Yeast Infection?

Recognizing symptoms of a yeast infection is the first step. Common signs include:

  • Vaginal itching or burning
  • Redness or swelling of the vulva
  • A thick, white, “cottage cheese”-like vaginal discharge
  • Discomfort or pain during sex or urination
  • Soreness or a mild itchy rash

The symptoms of a yeast infection can vary in severity. Mild yeast infections might only cause slight discomfort, while more severe infections can be pretty painful.

What Else Could It Be?

While a yeast infection is common, other conditions cause similar symptoms. Here’s what else your symptoms could mean:

1. Bacterial Vaginosis (BV)

BV is the most common vaginal infection in women of reproductive age. It occurs when the balance of healthy bacteria in the vagina changes. BV typically causes:

  • Thin, grayish vaginal discharge
  • A fishy odor, especially after sex
  • Mild itching or irritation

Unlike a yeast infection, BV does not cause thick discharge or intense itching.

2. Sexually Transmitted Infections (STIs)

Some sexually transmitted infections, such as chlamydia, gonorrhea, or trichomoniasis, can cause unusual discharge, itching, and discomfort. STIs often require prescription antibiotics and should not be self-treated with over-the-counter yeast infection treatments.

3. Allergic Reactions or Irritants

Products like scented soaps, vaginal sprays, or douches can irritate delicate vaginal tissues, causing itching or discharge without infection.

4. Other Vaginal Infections

Less common genital tract infections, skin conditions, or hormonal changes (like menopause) can mimic yeast infection symptoms.

How Is a Yeast Infection Diagnosed?

If you’re unsure whether your symptoms point to a vaginal yeast infection or something else, see your OB/GYN.

Your doctor will:

  • Ask about your symptoms and medical history
  • Perform a pelvic exam to check for redness, discharge, or swelling
  • Take a sample of vaginal discharge to examine under a microscope or send to a lab

This helps confirm whether you have a vaginal yeast infection, BV, an STI, or another condition.

What Are the Risk Factors?

Anyone can get a vaginal yeast infection, but some factors make you more likely to develop one:

  • Recent antibiotic use
  • Pregnancy or hormone changes (hormone therapy)
  • A weak immune system or HIV infection
  • Diabetes with high blood sugar
  • Taking birth control pills or hormone replacement therapy
  • Wearing tight, non-breathable clothing
  • Frequent douching or use of scented vaginal sprays

How Are Vaginal Yeast Infections Treated?

The good news is that most yeast infections are simple to treat. Depending on the severity, your doctor may recommend:

1. Antifungal Medication

For mild to moderate infections, antifungal medicine is the standard treatment. Options include:

  • Over-the-counter vaginal creams, ointments, or suppositories (such as miconazole or clotrimazole)
  • A single-dose oral antifungal medication, such as fluconazole, which requires a prescription

2. Prescription Treatments

If you have a complicated yeast infection, such as severe symptoms, frequent recurrences, or a weakened immune system, you may need a longer course of prescription antifungal medication or multiple doses of oral treatment.

How Long Do Yeast Infections Last?

Treatment length depends on the type and severity:

  • Mild yeast infections often clear up within a few days of starting treatment.
  • Most yeast infections improve within a week.
  • Complicated yeast infections may require up to two weeks of treatment.

If symptoms persist or return, follow up with your provider.

How to Prevent Yeast Infections

Prevention is key, especially if you experience recurrent yeast infections. Here are some tips to reduce your risk:

  • Wear breathable cotton underwear and avoid tight-fitting clothes.
  • Avoid douching and scented vaginal sprays.
  • Change out of wet swimsuits or workout clothes promptly.
  • If you need antibiotics, ask your doctor about ways to prevent yeast overgrowth.
  • Keep blood sugar levels in check if you have diabetes.
  • Maintain a healthy diet and consider probiotics to support healthy bacteria.

When to See a Doctor

See your OB/GYN if:

  • You’re unsure whether you have a yeast infection.
  • It’s your first time experiencing symptoms.
  • Symptoms don’t improve after using over-the-counter treatments.
  • You have recurrent yeast infections (four or more per year).
  • You develop unusual symptoms, like fever, abdominal pain, or sores.

Getting the correct diagnosis ensures you get proper treatment and relief.

Can a Yeast Infection Affect Other Parts of the Body?

While vaginal yeast infections are the most common, Candida can affect other body areas:

  • Oral thrush (mouth yeast infection)
  • Esophageal yeast infections (more common in those with a weak immune system or HIV infection)
  • Skin rashes or diaper rash in babies

In these cases, you’ll need medical treatment and a tailored plan.

Final Thoughts

Figuring out whether you have a vaginal yeast infection or another condition can be tricky. The best way to know for sure is to pay attention to your symptoms and see your OB/GYN for a proper diagnosis. While yeast infections are common and treatable, other vaginal conditions can mimic the same symptoms and require different treatments.
