Yeast infections and urinary tract infections (UTIs) are two different conditions that can cause some similar symptoms — discomfort in the genital area, burning and general irritation. But they are completely different, with different causes and treatments. Knowing the difference helps you get the right care.
Here’s how to tell them apart.

Key Differences
| Feature | Yeast Infection | UTI |
|---|---|---|
| What causes it | Yeast overgrowth (Candida) | Bacteria in the urinary tract |
| Where it affects | Vagina and vulva | Bladder and urethra |
| Discharge | Thick, white, clumpy | Usually none |
| Itching | Common — often intense | Rare |
| Burning with urination | Possible, from irritated skin | Common — from inside |
| Need to urinate often | No | Yes |
| Smell | Usually mild or yeasty | Sometimes strong urine smell |
| Treatment | Antifungal | Antibiotic |
Yeast Infection Symptoms
- Thick, white, cottage-cheese-like discharge
- Intense itching around the vulva
- Burning sensation, especially when urinating or during sex
- Redness and swelling of the vulva
- Pain during sex
- No real urinary urgency
UTI Symptoms
- Frequent urge to urinate
- Passing only small amounts of urine
- Burning pain on urination (from inside, not the skin)
- Cloudy or strong-smelling urine
- Lower abdominal pain or pressure
- Blood in urine
- Fever and back pain if kidney involvement
Can You Have Both?
Yes. Having both at the same time is possible and can make diagnosis harder. If symptoms don’t fit neatly into one category, it’s worth getting checked by a clinician.
Treatment
Yeast infection
- Antifungal tablet (fluconazole)
- Antifungal cream or pessary (clotrimazole)
- Available from pharmacies without prescription for mild cases
UTI
- Short course of antibiotics (nitrofurantoin, trimethoprim, or similar)
- Available through GP or Pharmacy First scheme in England
- Plenty of fluids
- Paracetamol for pain
When to See a Doctor
- Your first yeast or UTI diagnosis
- Recurring infections (more than 2-4 per year)
- Blood in urine
- Fever or back pain
- Symptoms during pregnancy
- Symptoms in men (UTIs are less common and need assessment)
- Symptoms that don’t improve with treatment
Prevention Tips
For yeast infections
- Avoid tight, synthetic underwear
- Don’t douche or use scented feminine products
- Wear cotton underwear
- Change out of wet swimwear or gym clothes promptly
For UTIs
- Drink plenty of water
- Urinate soon after sex
- Wipe from front to back
- Don’t hold urine for long periods

Frequently Asked Questions
Can yeast cause urinary symptoms?
Indirectly. Urine passing over irritated vulval skin can burn, mimicking a UTI. True urinary frequency and urgency usually suggest UTI rather than yeast.
Can I treat both at the same time?
If you genuinely have both, yes — antifungal for yeast and antibiotic for UTI. A clinician can confirm with testing.
Can antibiotics cause yeast infections?
Yes. Antibiotics can disrupt the normal vaginal bacteria and allow yeast to overgrow. This is a common side effect.
