UTI vs STD: How to Tell the Difference

Key Differences at a Glance

While both can cause discomfort in your genital area, UTIs and STDs affect different parts of your body:

• UTIs affect the urinary tract (bladder, urethra, kidneys)
• STDs affect the reproductive system and genitals
• UTIs cause urinary symptoms (burning while peeing, frequency, urgency)
• STDs often cause discharge, sores, or systemic symptoms

Classic UTI Symptoms

UTI symptoms are primarily focused on urination:

• Burning or pain when you urinate
• Urgent, frequent need to pee (even when your bladder is empty)
• Cloudy or strong-smelling urine
• Pelvic pressure or lower abdominal discomfort
• Blood in urine (sometimes)
• No unusual vaginal discharge

STD Symptoms to Watch For

Different STDs cause different symptoms, but common signs include:

• Unusual vaginal discharge (yellow, green, or gray)
• Genital sores, bumps, or blisters
• Burning that persists outside of urination
• Itching in the genital area
• Pain during sex
• Bleeding between periods
• Flu-like symptoms (fever, body aches, swollen lymph nodes)

Which STDs Mimic UTI Symptoms?

Some STDs can cause burning urination similar to a UTI:

• Chlamydia — May cause burning urination and discharge; often has no symptoms
• Gonorrhea — Can cause painful urination and unusual discharge
• Trichomoniasis — May cause burning urination along with itching and discharge
• Herpes — Can cause painful urination if sores are present near the urethra
• Mycoplasma genitalium — Often causes UTI-like symptoms

When It Might Be an STD

Consider STD testing if:

• You have a new sexual partner or multiple partners
• You notice unusual discharge (color, consistency, odor)
• You have genital sores or blisters
• Your partner has been diagnosed with an STD
• UTI treatment doesn't resolve your symptoms
• You have burning that occurs outside of urination

When It's Likely a UTI

It's probably a UTI if:

• Burning occurs specifically during urination
• You have urgent/frequent need to pee
• No unusual vaginal discharge
• No genital sores or visible changes
• Symptoms came on suddenly (not gradually)

Can You Have Both?

Yes, it's possible to have both a UTI and an STD at the same time. If you have risk factors for STDs and aren't sure what's causing your symptoms, getting tested for both is wise. Treatment for one won't cure the other.

Getting the Right Diagnosis

For classic UTI symptoms without STD risk factors, online treatment through a licensed clinician is often appropriate. If you suspect an STD or have unclear symptoms, you may need laboratory testing for accurate diagnosis. Either way, don't ignore symptoms hoping they'll resolve.
