7 Signs To Not Ignore If You’ve Had A UTI Before

Unfortunately, women are so good at powering through discomfort that they often miss subtle signs that shouldn’t be ignored. Once you've had a UTI, you start to develop a mental checklist of what it should feel like, and that can actually work against you.

Subtle early signs like slightly cloudy urine or a faint change in smell often get dismissed or attributed to something else entirely. “What concerns me most is when women assume that because symptoms don't feel as bad as their last UTI, it must not be a UTI,” explains Carly Ross, OB/GYN and medical advisor to Winx Health. “This is exactly when infections are left undiagnosed and untreated, and have the opportunity to become much more serious.”

And she's not wrong. A UTI that goes unchecked can escalate quickly, sometimes spreading to the kidneys or, in more serious cases, the bloodstream. The tricky part is that the signs that indicate that it's getting worse don't always look like what you'd expect.

Below, we've asked multiple experts for their insights on seven signs to not ignore if you've had a UTI before — because left untreated, what starts as a minor infection can turn into something that lands you in the ER.

1. Waking Up More Frequently At Night

If you’re waking up to pee a lot more frequently throughout the night, it might be a sign of another UTI. But it’s not just a one-off extra trip — this looks more like suddenly jolting awake two, three, even four times, with a persistent urge that feels hard to ignore, even if only a small amount of urine comes out. You might find yourself lying back down only to feel that same pressure creep back minutes later. “Many assume it's just aging or hydration-related, rather than a potential sign of infection,” explains Ross.

2. Pelvic Pain Or Pressure

Women with UTIs often get used to low-grade symptoms, such as suprapubic pain, which is a dull discomfort in the lower abdomen or bladder that is frequently mistaken for bloating. “We don’t normally feel the bladder unless we need to urinate, but feeling a fullness, pressure or discomfort between urinations can be a symptom, indicating a very early bladder infection,” explains Dr. Prudence Hall, a gynecologist and pioneer in regenerative medicine.

3. Unpleasant Odor In Urine

Another indicator is an unpleasant odor in the urine, which may reflect bacterial overgrowth, particularly in those with urinary stasis. It’s often described as noticeably stronger than usual — sharp, sour, or even slightly sweet — and tends to linger rather than dissipate quickly. You might catch a whiff before you even flush or notice that the smell seems “off” despite being well-hydrated. Because it can be subtle at first, it’s easy to brush off as something dietary or temporary, but a consistent change in odor is worth paying attention to.

4. Mistaking Symptoms For A Yeast Infection

According to Ross, it’s important to note that both UTIs and yeast infections can cause overlapping symptoms, including discomfort, frequent urination, and pelvic pain, which is why so many people wait, unsure of what they're actually dealing with. “That uncertainty is exactly why testing matters,” she explains. “The treatments are completely different, and guessing wrong only delays real relief.”

5. Mental Fog Or Fatigue

Mental fog or fatigue in elderly or diabetic patients can be an early warning sign of something more serious, like urosepsis. “In some cases, a subtle change in mentation or increased fatigue may be the only presenting symptom of urosepsis,” says Dr. Peter Balazs, a board-certified gynecologist.

6. Loss Of Glycemic Control

A loss of glycemic control or unexplained hyperglycemia in a previously well-controlled diabetic patient can signal an underlying infection beyond a UTI, according to Balazs. In practical terms, this might look like blood sugar readings that are suddenly higher than usual for no clear reason, numbers that stay elevated despite sticking to your normal routine, or needing more insulin than expected to bring levels down. For some, it’s the first clue that the body is under stress — well before more obvious infection symptoms appear.

7. Blood In Your Urine

UTIs generally follow a similar set of symptoms with each person, such as frequency of urination and burning pain. “But if symptoms feel different, I suggest getting a urinary culture to rule out a bladder infection and seeing your PMD or urologist to make sure other urinary problems are not present,” says Hall. “Especially if blood is in the urine, medical advice is advised.”

Why People Wait Too Long To Seek Treatment

Unfortunately, having had a UTI before can actually work against you. Sometimes, when you’re familiar with the infection, it can often create a false sense of certainty — if you've felt it before, you assume you know what it is and how to handle it. That might mean waiting it out, reaching for cranberry juice, or even taking leftover antibiotics from a previous prescription instead of seeing a doctor.

And the more UTIs you've had, the easier it is to normalize the discomfort and treat it as an annoying inconvenience rather than a medical issue that needs attention. But that complacency can be dangerous because symptoms can vary from infection to infection, and what feels like a familiar UTI could be something that needs more urgent care than you'd expect.

According to Ross, there are many household products marketed as UTI solutions that people believe they're treating the infection, when they're only masking symptoms. “Cranberry juice is the most common example of this — while it might ease discomfort, it doesn’t eliminate the bacteria that are causing the infection,” she explains. “Historically, getting a proper diagnosis also meant an urgent care visit and time in a waiting room, which is a barrier for anyone with a busy life.”

The good news is that awareness around UTIs and the importance of proper care has continued to grow, making it easier for people to recognize symptoms early and seek the support they need before symptoms worsen.
