UTI vs vaginal infection: what's the difference?

Bottom lineA UTI affects the urinary system, causing burning when you urinate, urgency, and cloudy urine without vaginal discharge, and needs antibiotics; a vaginal infection affects the vagina, causing itching and abnormal discharge (yeast) or a fishy odor (BV). The quick rule: burning when you pee points to a UTI, while itching, discharge, or odor points to a vaginal infection; see a doctor for UTI symptoms promptly or if you're unsure, since you can have both.

UTIs and vaginal infections are easy to confuse because both affect the same area, but they involve different parts of the body and need different treatment.

Urinary tract infection (UTI)

A UTI affects the urinary system (bladder and urethra), not the vagina.

• Main symptoms: burning when you urinate, needing to pee often and urgently, cloudy or strong-smelling urine, lower-belly or back discomfort
• No vaginal discharge as a primary symptom
• Treatment: antibiotics

Vaginal infection (yeast or BV)

These affect the vagina itself.

• Yeast: thick white discharge and intense itching, no strong odor
• BV: thin gray discharge with a fishy odor, little itching
• Treatment: antifungal (yeast) or prescription antibiotics (BV)

The quick distinction

• Burning when you pee, frequent urge = think UTI
• Itching, abnormal discharge, or odor = think vaginal infection

There is overlap: vaginal infections can sometimes cause burning, and you can have both at once, which is why testing helps when you're unsure.

When to see a doctor

• UTI symptoms - get treated promptly; untreated UTIs can spread to the kidneys
• Blood in urine, fever, or back pain - more urgent
• Recurrent UTIs or vaginal infections
• Symptoms during pregnancy

If you're not sure which you have, a clinician can test quickly. For vaginal infections specifically, see our complete vaginal health guide.

Track urinary and vaginal symptoms separately in Femora so you can describe them accurately to a clinician.
