Why Your Uti Test May Be Negative Even When You Have Symptoms
How about a study that looked at bacterial DNA in the urine of women with UTI-like symptoms who also had a negative culture test?
To summarize, the researchers looked at urine samples of women without symptoms and a group with UTI-like symptoms. They performed two tests: a culture test and a DNA-sequencing test that allows identifying if there is any bacterial DNA in the urine.
According to the study, 90.5% of symptomatic women with a negative urine culture tested positive for Escherichia coli bacteria with molecular methods compared to about 5.3% of women without symptoms.
This allowed the researchers to conclude that culture tests might not be sufficiently accurate and if a patient complains of urinary tract infection symptoms, she might as well be treated for an acute UTI.
The findings are gaining traction among chronic UTI sufferers who feel that the study finally gives more credibility to their complaints.
However, argues Dr. Hawes the significance of finding bacterial DNA may be different than the significance of finding live growing bacteria. Does the DNA stay around after an infection? If so, for how long? How do you determine antibiotic sensitivity based on DNA findings rather than live growth?.
As Dr. Hawes concludes, We dont yet understand the clinical significance of this data. In other words, do not dismiss the results of your culture test because of this study.
What About Cranberry Juice For Uti
Its a long-held belief that consuming cranberry juice may help prevent and treat urinary tract infections. While its true that cranberries contain an active ingredient that can prevent adherence of bacteria to the urinary tract, there is still no evidence that cranberry products can treat a UTI.
One of the reasons: Products like cranberry juice or cranberry capsules are not explicitly formulated with the same amount of PACs that have shown potential in lab studies. Moreover, a 2019 report in the Journal of Urology noted that the availability of such products to the public is a severe limitation to the use of cranberries for UTI prophylaxis outside the research setting.
In all, theres actually very little high-quality research on the topic of prevention. For instance, a 2016 study in The Journal of the American Medical Association, found that among female nursing home residents, daily consumption of cranberry capsules resulted in no significant prevention of UTIs.
While consuming cranberry juice or supplements is not considered a first-line treatment of urinary tract infections, in most cases, it cant hurt. After all, drinking plenty of liquids does dilute your urine and help spur more frequent urination, which flushes bacteria from the urinary tract. The exception: Those who are taking blood-thinning medication, such as warfarin, should not consume cranberry juice. And those with diabetes should be mindful of the high-sugar content of fruit juices.
Signs That Uti Is Not Responding To Antibiotics
What if you feel lower back pain? Is this a sure sign that infection is progressing to the kidneys and antibiotics are not working?
While lower back pain could be an important sign of kidney infection, in many cases low back pain alone is not a sure sign that bacteria ascended to the kidneys, it could be just pain radiating from the bladder due to UTI, clarifies Dr. Hawes. However, if you are experiencing fever and/or nausea, these are very serious symptoms and you should seek immediate medical attention.
This is when the chances are higher to get sick with an infection caused by antibiotic-resistant bacteria:
- You underwent multiple UTI treatments in your lifetime
- If you have been using the same antibiotic for previous infections
- Stopped taking antibiotics and didnt finish all the pills that your doctor prescribed you
- If you are guilty of keeping a stash of antibiotics and self-treating UTIs, cold, travel diarrhea, etc.
- Youve been recently hospitalized
- If you are immunosuppressed or have any serious chronic health issues, for example, uncontrolled diabetes.
Dr. Hawes highlights that it is important to request a urine culture test before deciding on a type of antibiotic. If you are taking multiple antibiotics without checking bacterial drug sensitivity, its a guessing game that only increases your chances to develop resistant bacteria.

How Long Does A Complicated Uti Last
Complicated UTIs can last a couple of weeks. According to theAmerican Urological Association, a number of different factors can determine if a UTI is complicated, including:
- whether you’re pregnant or post-menopausal
- if it’s caused by bacteria that’s resistant to multiple drugs
- something abnormal in your urinary tract
- if you have a catheter, stent, nephrostomy tubes, or other medical devices
- if you have a chronic condition, like diabetes or a compromised immune system
If you’ve got a complicated UTI, you’ll need treatment with a longer course of oral antibiotics, and potentially intravenous antibiotics, as well, per the AUA. But while treatment will last 14 days, you’ll probably feel better much sooner. “As your body starts to fight infection, that burning with urination will improve,” says Dr. Moore.
How Long Do Utis Last In Men
UTIs can last up to 14 days in men, says AUA. It’s less common for men to get UTIs, but when they do get this type of infection, it’s considered complicated and treated on the same timeline as complicated UTIs in women.
The AUA recommends that men take antibiotics for seven to 14 days if they have a bladder infection. As for kidney infections, men should get care right away to avoid a more serious condition and will probably need to take antibiotics for 14 days. The first couple days might involve IV antibiotics in the hospital, and assuming that goes well, the doctor will switch you over to oral antibiotics for the rest of the treatment.

What To Expect At Home
UTIs can lead to infection. Most often the infection occurs in the bladder itself. At times, the infection can spread to the kidneys.
Common symptoms include:
- Pain or burning when you urinate
- Needing to urinate more often
- Hard to empty your bladder all the way
- Strong need to empty your bladder
These symptoms should improve soon after you begin taking antibiotics.
If you are feeling ill, have a low-grade fever, or some pain in your lower back, these symptoms will take 1 to 2 days to improve, and up to 1 week to go away completely.

UTI is less common among men when compared to women since they have the longer bladder that makes it hard to spread out.Urinary tract infection may be caused by a sexually transmitted disease. Sometimes a kidney stone in the urinary tract blocks the flow of urine and causes an infection. In older men, an enlarged prostate can cause a urinary tract infection by keeping urine from draining out of the bladder completely.Infection might also be caused by the use of a catheter used to drain the bladder or by urethral stricture, which is a narrowing of the urethra by scar tissue from previous infections or surgical procedures.After treatment of the infection in men, it only takes 24hours for the symptoms to disappear. If it is not treated, the infection can permanently damage the bladder and kidneys, or it may spread to the blood. If the infection spreads to the blood, it can be fatal.

Cephalexin Could Promote Yeast Infection
Beneficial bacteria Lactobacilli are present in healthy vaginas and help to maintain an acidic pH that deters pathogens and yeast.
Like any other antibiotic, taking full dose Cephalexin regularly can deplete your good bacteria and yeast infection may be a side effect.
Unfortunately, once your good bacteria are depleted, you are not only more likely to get a yeast infection but also more vulnerable to infection from your own E. coli. This, in turn, could lead to recurrent UTIs.
How Do You Know When A Uti Becomes A Kidney Infection
When you do not see a doctor, a urinary tract infection can swiftly turn into a kidney infection, which can be very serious to your long-term health.
Urinary tract infections are one of the most common types of infection, second only to respiratory infections. They account for over 8.3 million visits to hospitals and health care providers each year. An untreated UTI may lead to a kidney infection, this is a potentially life-threatening condition.

When Do Uti Symptoms Disappear
As previously mentioned, antibiotics should help dissipate your UTI symptoms within one to two days. Your doctor might prescribe a treatment plan lasting anywhere from 3 to 14 days.
If youve been battling more severe UTI symptoms, such as low-grade fever or lower back pain, the process could take slightly longer. While mild improvements should be spotted in the first couple of days, your infection will likely need up to one week to completely go away.
When To See A Healthcare Professional
You should only take antibiotics under the direction of a healthcare professional. If your symptoms worsen or aren’t resolved after your full course of antibiotics, talk to your healthcare provider about additional treatment options.
You should also alert your healthcare provider to any side effects you experience while taking antibiotics, even if they are minor. Go the emergency room or seek immediate medical care if you experience symptoms of an allergic reaction while taking antibiotics.

Your doctor is a resource to help you understand what type of UTI you have, how severe it is, and the best course of action for treatment. The good news is that your discomfort can be over in a matter of days if you take steps now to address it.
Cephalexin Could Increase The Risk Of Repeated Utis
Cephalexin belongs to a category of antibiotics called cephalosporins.
I recently came across a study that demonstrated that another drug from the cephalosporin group promotes vaginal colonization with Escherichia coli , the number one bacteria causing UTIs.
The study looked at monkeys and the antibiotic was placed directly into the vagina . While another study shows that low dose daily cephalexin does not affect the vaginal flora, it is definitely possible that if you take full dose Cephalexin regularly, this e may have a detrimental effect on the vaginal microbiome.
Unfortunately, if your vagina is colonized with E. coli, you are almost guaranteed to have repeated UTIs after sex.
Healthy vaginas normally have the ability to deter E. coli bacteria and therefore play a key role in preventing UTIs. If your vaginal health is compromised, your risk of chronic UTIs is higher.

Is It Safe To Take Antibiotics Long
While there are some common side effects and risk for creating antibiotic-resistant bacteria, it is safe to take antibiotics preventively under the guidance of your physician.
If you have recurring UTIs , you may benefit from a low-dose prophylactic antibiotic, Dr. Sussman said. Some may require intermittent treatment at the sign of symptoms, while others may require a single dose after sexual intercourse or when symptoms occur. However, its important you discuss the underlying causes with your doctor before being prescribed antibiotics prophylactically.
Creating Stronger Strains Of Bacteria
Over time, some species of bacteria have become resistant to traditional antibiotics. According to some research , several species of E. coli, the primary cause of UTIs, are showing increasing drug resistance.
The more a person uses an antibiotic, the greater the risk of the bacteria developing resistance. This is even more likely when people do not follow a doctors instructions to complete the full prescribed course of treatment.
It is essential to continue a course of antibiotics until the end date that the doctor provides. People should also never share antibiotics with others.

Personally, I have taken Cephalexin to treat my UTIs twice sat other times I was prescribed Macrobid and Cipro. To be frank, I tolerate antibiotics very well, but this doesnt mean that I like them. Unfortunately, antibiotics are sometimes a necessary evil.
Here are some of my tips for successfully taking antibiotics for your UTI.
First of all, make surethat antibiotics are the right choice for you. If you only have bladder pain and it burns during or after urination but your urine is clear, antibiotics might not be the best solution. In fact, if you keep having UTIs, you might need to dig a little deeper to address the root cause of your UTIs, rather than simply repeating the cycle of antibiotic treatment.
If you see blood in your urine, its cloudy or has a strange smell, it may be time for antibiotics. Also, if you have fever or chills, pain in your flank and are not able to keep anything down, its really time to see your doctor.

Common Questions About Trimethoprim
Trimethoprim kills bacteria by stopping them making a substance called folic acid, which they need to survive.
This is why trimethoprim can sometimes cause low folic acid levels in your blood over time.
You should feel better within a few days.
It’s important that you keep taking trimethoprim until your course is finished.
Do this even if you feel better. It will help stop the infection coming back.
Tell your doctor if you do not start feeling better after taking trimethoprim for 3 days, or if you start to feel worse at any time.
Some people get a fungal infection called thrush after taking a course of antibiotics like trimethoprim.
It happens because antibiotics kill the normal harmless bacteria that help to protect you against thrush.
Ask your pharmacist or doctor for advice if this happens to you.
Yes. Trimethoprim should not affect you being able to drive or cycle.
There’s no evidence to suggest that taking trimethoprim reduces fertility in either men or women.
But if you’re trying to get pregnant and you are taking trimethoprim every day, talk to your doctor, as this medicine is not usually recommended in early pregnancy. They may recommend changing to another antibiotic, or they may also prescribe high dose folic acid .
How Long Does Treatment Last
Treatment for complicated UTIs tends to take longer compared with simple UTIs, and may take between 7 and 14 days. While a course of antibiotics may treat a typical UTI at home, complicated cases may require broad-spectrum, intravenous antibiotics as well as hospitalization.
The exact treatment timeline depends on how soon your body responds to broad-spectrum antibiotics, as well as whether any complications develop.
Complicated UTIs are most common in people predisposed to risks from infections. The following may increase your risk for complicated UTI:
- age, older adults and young children
