UTI or Vaginal Infection? How to Tell the Difference
Burning can mean different things — here's how to tell them apart
Quick answer: A UTI usually causes burning when urinating, frequent urges to pee and lower belly pain, while a vaginal infection more often causes itching, irritation and changes in discharge or odor. Because symptoms overlap, a urine test and vaginal swab at a clinic give the right diagnosis and treatment.
A burning feeling "down there" can come from a urinary tract infection (UTI) or a vaginal infection — and they need different treatments. Here's how to tell the difference and when to see a doctor.
Signs Pointing to a UTI
- Burning or pain when urinating
- Needing to urinate frequently or urgently
- Passing only small amounts of urine
- Cloudy, strong-smelling or bloody urine
- Lower abdominal pressure
Signs Pointing to a Vaginal Infection
- Itching, irritation or soreness of the vulva or vagina
- Changes in discharge — thick and white (yeast), thin and gray with a fishy smell (BV) or yellow-green and frothy (trichomoniasis)
- Burning when urine touches irritated skin
- Pain during sex
Why the Difference Matters
UTIs are treated with antibiotics targeting the urinary tract. Yeast infections need antifungal medicine, and BV or trichomoniasis need specific antibiotics. Taking the wrong treatment can delay relief.
How Doctors Tell Them Apart
- Urine test: checks for signs of infection in the urinary tract; a culture may identify the bacteria.
- Vaginal swab: checks for yeast, BV and STIs.
Sometimes both are present at the same time.
When to Seek Care Quickly
- Fever, chills or back or side pain — possible kidney infection
- Blood in the urine
- Symptoms during pregnancy
- Symptoms that return frequently
Simple Prevention Tips
- Drink enough water
- Urinate after sex
- Avoid douching and scented products
- Wear breathable underwear
Getting Tested
An OB-GYN can test for both UTIs and vaginal infections in one visit and prescribe the right treatment.
