Many vaginal and genital symptoms can overlap, which can make it difficult to know the exact cause without testing.

Precision Health’s online testing services makes it simple to get fast, confidential results as early as same-day. Learn more about the testing process and order your test online today!

What is a Yeast Infection?

A yeast infection is a common, non-sexually transmitted condition caused by an overgrowth of Candida, a type of fungus that naturally lives in the body. While it’s not considered an STD, sexual activity can sometimes trigger or worsen a yeast infection due to changes in vaginal pH or irritation. Common symptoms of a yeast infection include:
  • Intense itching or irritation in the vagina or vulva
  • Thick, white, odorless discharge
  • Redness or swelling of the vulva
  • Burning during urination or intercourse
Yeast infections are very common and can often be treated with over-the-counter antifungal medications. However, if you’re experiencing symptoms for the first time– or if treatment doesn’t work– it’s important to rule out other causes, including STDs

STD Symptoms That Can Mimic a Yeast Infection

Certain STDs can cause symptoms that look and feel like a yeast infection, especially in the early stages. This includes infections like:
  • Chlamydia
  • Gonorrhea
  • Trichomoniasis
  • Genital herpes
  • Bacteria vaginosis (not an STD but often confused with one)
STD symptoms that overlap with yeast infections include:
  • Unusual vaginal discharge (yellow, green, or frothy in some cases)
  • Itching or irritation
  • Burning during urination
  • Pain during sex
  • Redness, sores, or bumps (especially with herpes)
The key difference? STDs often produce a change in discharge color or smell, additional pelvic pain, or the presence of sores or lesions– all of which are not typical in yeast infections. Unlike yeast infections, STDs may not improve with antifungal treatment.

When To Get Tested

If you’re unsure whether your symptoms are caused by a yeast infection or an STD, it’s best to get tested– especially if you:
  • Recently had unprotected sex
  • Have a new sexual partner
  • Are experiencing unusual or persistent symptoms
  • Aren’t responding to yeast infection treatments
With our convenient online testing service, you can order the right test, drop off your sample at a nearby collection site, and get your results as early as same-day. No waiting rooms, no provider visit– just fast and confidential answers.
