More than half of all women will have at least one urinary tract infection in their lifetime. In fact, the lifetime risk of UTIs among women is over 60%, and UTIs result in approximately 10.5 million office visits and 3 million emergency department encounters in the US every year. For something so common, UTIs can still be confusing — especially when symptoms overlap with other infections, or when it's hard to tell how serious things are getting.
We’ll cover exactly what UTI symptoms feel like, what they mean, when to act fast, and how to get treated quickly without leaving home.
A urinary tract infection happens when bacteria enter and multiply somewhere in your urinary system — your bladder, urethra, ureters, or kidneys.
Most UTIs start when bacteria, typically E. coli from the digestive tract, travel into the urethra and make their way to the bladder. Once bacteria take hold and multiply, the lining of your bladder becomes inflamed, which is what causes the characteristic burning and urgency you may recognize.
UTIs occur at least four times more frequently in females than males. Anatomy plays a big role: a shorter urethra means bacteria have a shorter distance to travel to reach the bladder. The proximity of the urethra to the vagina and rectum also makes it easier for bacteria to migrate. Hormonal shifts, pregnancy, and sexual activity all add to the picture.
Most UTIs are bladder infections (cystitis) — uncomfortable but typically not dangerous when treated promptly. When an infection travels up to the kidneys, it becomes pyelonephritis, which is more serious and requires immediate care. Knowing the difference between the two matters, and we'll walk through both below.
These are the signs most commonly associated with a bladder infection. If several of these sound familiar at once, a UTI is a likely explanation.
If a UTI is left untreated, bacteria can travel from the bladder up to the kidneys. A kidney infection is a more serious condition that often requires stronger antibiotics and, in some cases, hospitalization.
Pain in your mid-to-upper back or sides (the "flank" area), especially if it's accompanied by fever and chills, suggests the infection has reached your kidneys. This is distinct from the lower abdominal discomfort of a bladder infection. There are an estimated 250,000 cases of pyelonephritis (kidney infection) annually in the US, and 7% of cases require hospital admission.
Feeling nauseous or vomiting alongside UTI symptoms is another signal that the infection may have moved to the kidneys. These symptoms show that the body is mounting a more significant response to the infection.
Seek emergency care if you have a high fever (above 103°F), severe back pain, vomiting, confusion, or if you are pregnant. Untreated kidney infections can lead to a serious bloodstream infection (urosepsis), which is life-threatening. Don't wait to see if things improve on their own at this point.
Several common vaginal and urinary conditions share overlapping symptoms, which is why it's easy to misidentify what's going on.
All three — UTIs, yeast infections, and bacterial vaginosis (BV) — can cause discomfort in the genital area, but they each have distinct features:
Because these conditions respond to different treatments, getting an accurate diagnosis matters. If you're not sure which one you're dealing with, that's completely normal — these conditions genuinely overlap.
A quick consultation with a Twentyeight Health provider can give you a clear answer and the right treatment, without a waiting room. Check if your insurance is accepted here.
Yes. Taking antibiotics for a UTI can sometimes trigger a yeast infection, since antibiotics disrupt the natural bacterial balance in the vaginal area. If you've been treated for a UTI and start noticing itching and unusual discharge, it's worth checking in with your provider.
Pregnancy changes a lot about how your body functions, including how your urinary tract works — and UTIs during pregnancy carry added risk.
During pregnancy, hormonal and physical changes make it easier for bacteria to travel to the kidneys. An untreated UTI during pregnancy can increase the risk of preterm labor and low birth weight. For this reason, providers routinely screen for UTIs at prenatal visits, even without symptoms.
Frequent urination is already a normal part of pregnancy, which means one of the most common UTI symptoms can go unnoticed. These are the other signs that tend to fly under the radar:
If any of these sound familiar, a simple urine test can confirm or rule out an infection quickly. Twentyeight Health serves people across all 50 states and accepts 100+ insurance plans, making it easy to get care when you need it.
Diagnosing a UTI is usually quick and straightforward. A urine test is the standard first step — here's what providers are actually looking for when they run one.
A standard urinalysis checks for white blood cells (a sign of infection), red blood cells, bacteria, and nitrites (a byproduct of bacterial activity). A urine culture may also be ordered to identify the specific bacteria and confirm which antibiotic will work best.
Over-the-counter UTI test strips can detect nitrites and leukocyte esterase in urine, and they're a reasonable first step if you want quick information. They're not as accurate as a lab test, though — they can produce false negatives, especially early in an infection or with certain bacteria. A negative at-home test doesn't definitively rule out a UTI if you're still having symptoms.
You don't need to schedule an in-person appointment to get a UTI diagnosis and prescription. Telehealth providers can evaluate your symptoms, review your history, and send a prescription to your local pharmacy — often within hours. Twentyeight Health offers same-day UTI consultations and connects you with licensed providers entirely online.
Once a UTI is confirmed, treatment is typically simple and fast-acting. The type of antibiotic prescribed can vary depending on your health history, so it's worth understanding your options.
Antibiotics are the standard treatment for UTIs, and they work well when prescribed correctly. The most commonly prescribed options include:
Your provider will choose based on your health history, any allergies, and local antibiotic resistance patterns. Most uncomplicated bladder infections clear up within a few days of starting treatment.
Sometimes. Many uncomplicated UTIs resolve spontaneously without treatment, but people often seek therapy for symptom relief NCBI, and untreated UTIs carry the real risk of spreading to the kidneys. Waiting it out is not generally recommended, especially if symptoms are worsening or you've had kidney infections before.
Products like AZO contain phenazopyridine, which can numb the lining of the urinary tract and reduce the burning sensation. They don't treat the infection itself, but they can take the edge off while you wait for antibiotics to work. Other supportive measures worth trying in the meantime:
Think of all of the above as comfort care — helpful, but not a substitute for antibiotics.
