Urinary tract infections (UTIs) and yeast infections are both common—and uncomfortable—conditions, but they have different causes, symptoms, and treatments. Understanding the differences can help you get the right care faster and avoid unnecessary complications.
Urinary Tract Infections (UTIs)
A urinary tract infection (UTI) is an infection that can occur in any part of the urinary system, including the kidneys, ureters, bladder, and urethra [1]. Most UTIs affect the lower urinary tract—particularly the bladder and urethra—and can cause uncomfortable symptoms like pain and frequent urination [1]. While many UTIs are mild, untreated infections can spread to the kidneys and lead to more serious complications [2].
Causes of UTIs
UTIs are usually caused by bacteria—most commonly E. coli—entering the urinary tract through the urethra and reaching the bladder [2].
You may be at higher risk if you:
- Have had UTIs before
- Are sexually active
- Use diaphragms or spermicide
- Are menopausal
- Have urinary tract abnormalities
- Have a weakened immune system
- Use a catheter
- Recently had urogenital surgery
UTI Symptoms
Symptoms of a urinary tract infection (UTI) can vary depending on which part of the urinary system is affected, but many people experience a consistent set of warning signs [2].
Common UTI symptoms include:
- A burning sensation when urinating
- A strong, persistent urge to urinate
- Frequent urination, often passing small amounts
- Urine that appears red, pink, or cola-colored (a sign of blood)
- Pelvic pain or pressure, especially in the lower abdomen
When the infection spreads beyond the bladder, symptoms may become more severe.
Signs of a more serious (kidney) infection include:
- Back or side pain
- High fever, chills, or shaking
- Nausea or vomiting
If you notice any of these symptoms—especially signs of a more severe infection—it’s important to seek care promptly to prevent complications.

Yeast Infections
Yeast infections occur when there is an overgrowth of yeast in the vaginal area. Up to three out of four women will experience one at some point in their lives [3].
While yeast is normally present in the body, disruptions—such as antibiotic use—can cause it to grow out of balance.
What Causes Yeast Infections?
Yeast infections develop when a naturally occurring fungus called Candida grows out of balance in the body [3]. Normally, healthy bacteria help keep this fungus in check—but certain factors can disrupt that balance, allowing yeast to multiply and cause an infection [3].
Common causes and contributing factors include:
- Antibiotic use, which can reduce beneficial bacteria
- Hormonal changes, such as pregnancy, birth control use, or menstrual cycles
- A weakened immune system
- Uncontrolled diabetes, which can promote yeast growth
- Lifestyle factors like tight clothing, prolonged moisture, or use of scented products [3]
Yeast Infection Symptoms
Symptoms of a yeast infection can vary from mild to more uncomfortable, but they typically affect the vaginal and vulvar area [3].
Common symptoms include:
- Itching or burning in and around the vagina
- Redness and swelling of the vulva
- Thick, white vaginal discharge that may resemble cottage cheese
- Burning during urination
- Pain or discomfort during sex
- Small cracks or irritation in the skin around the vagina [3]
Because these symptoms can overlap with other vaginal conditions, it’s important to consult a healthcare provider for an accurate diagnosis and appropriate treatment.
Comparing UTIs and Yeast Infections
| Feature | Urinary Tract Infection (UTI) | Yeast Infection |
|---|---|---|
| Cause | Bacterial infection (commonly E. coli) | Fungal overgrowth (usually Candida) |
| Where it occurs | Urinary tract (bladder, urethra, kidneys) | Vagina and surrounding tissue |
| Common symptoms |
|
|
| Discharge | Typically none | Common (thick, white, odorless) |
| Odor | Urine may smell strong or foul | Usually minimal or “yeasty” odor |
| Itching | Rare | Common |
| Pain location | Lower abdomen, pelvis, or back | External vaginal area (vulva) |
| Typical treatment | Antibiotics | Antifungal medications |
| Can resolve on its own? | Unlikely—treatment recommended | Sometimes, but treatment is usually needed |
| Risk factors | Sexual activity, anatomy, menopause, catheter use | Antibiotics, hormones, diabetes, weakened immune system |
Treatment Options and Outlook
Both yeast infections and UTIs are common—and the good news is that they’re typically treatable with the right medications. Yeast infections are usually managed with antifungal treatments, such as creams, suppositories, or oral medications, with many mild cases resolving within a few days [3]. UTIs, on the other hand, are most often treated with antibiotics, and symptoms often begin to improve within a few days of starting treatment, though it’s important to complete the full course as prescribed.
If your symptoms are severe, don’t improve, or keep coming back, it’s important to follow up with a healthcare provider for further evaluation and a tailored treatment plan.
