Urinary tract infections are a prevalent form of infection in the urinary system. It can affect any area of the urinary system. Bacteria, specifically E. coli, are the most common cause of UTIs. Symptoms include the desire to pee frequently, pain while peeing, and pain in your side or lower back. Antibiotics can treat the majority of urinary tract infections.
Overview
What is a UTI (Urinary Tract Infection)?
A urinary tract infection (UTI) is an infection that affects your urine system. This form of illness may affect your:
Urethral (urethritis).
Kidneys (pyelonephritis).
Bladder (cystitis).
Urine (pee) is a byproduct of the blood-filtering system that your kidneys manage. Your kidneys produce urine as they eliminate waste and extra water from your blood. Pee generally passes through your urinary system without being contaminated. However, bacteria can enter your urinary system and cause UTIs.
What is the urinary tract?
The urinary system produces and stores urine. This includes your:
Kidneys are little, bean-shaped organs located at the back of your body, above your hips. Most people possess two kidneys. They remove water and waste items from your blood, resulting in urine. Common wastes include urea and creatinine.
Ureters. Your ureters are narrow tubes that transport urine from the kidneys to the bladder.
Bladder. Your bladder is a balloon-like organ that holds urine before it exits your body.
Urethra. The urethra is a tube that transports urine from the bladder to the exterior of the body.
How prevalent are urinary tract infections?
UTIs are extremely frequent, especially in women. Approximately half of all girls will have a UTI at some point in their lives. UTIs can affect both men and children, however only 1% to 2% of youngsters develop them. Every year, healthcare providers treat 8 to 10 million people for urinary tract infections.
What are the symptoms of a urinary tract infection?
A UTI causes inflammation in the lining of the urinary tract. Inflammation may cause the following problems:
Pain in the side, abdomen, pelvis, or lower back.
Lower pelvic pressure.
Pee that is cloudy and smells nasty.
Urinary incontinence.
Urinate frequently.

Additional UTI-related symptoms may include:
Pain in your penis.
Feeling incredibly exhausted.
Fever.

Urinary tract infections are caused by microorganisms, most commonly bacteria. They usually enter through the urethra and can infect your bladder. The infection can also spread from your bladder to your ureters and eventually into your kidneys.
What is the leading cause of a urinary tract infection?
E. coli accounts for more than 90% of bladder infections. E. coli is frequently found in the lower intestine (large intestine).
Who has the highest chance of developing a urinary tract infection?
A urinary tract infection can affect anyone, but those without a penis are more likely to develop one. This is because your urethra is shorter and closer to your anus, where E. coli germs thrive.
Can you catch a UTI via your fingers?
Yes, it is possible to develop a UTI via your fingers. When your hands come into contact with a surface, bacteria and other microbes can be transferred. When you use the restroom or perform sexual behaviors such as masturbation or fingering, you may unknowingly introduce bacteria into your urethra.

How will you know if you have a UTI?
If you have signs of a urinary tract infection, consult a healthcare provider. They will quiz you about your symptoms, evaluate your medical history, and perform a physical examination. They may also request tests to help confirm a diagnosis.
What tests will be performed to diagnose a urinary tract infection?
A healthcare provider may order the following tests to identify a urinary tract infection:
Urinalysis. During this test, you will urinate in a specific cup. The provider will send the sample to a laboratory, where technicians will look for evidence of a UTI using a variety of factors including nitrites, leukocyte esterase, and white blood cells.
Urine culture. You'll urinate in a specific cup, and lab technicians will grow and identify any bacteria present in your sample. Urine cultures are crucial because they assist your provider in determining the best course of treatment.
If your infection does not respond to therapy, your doctor may order the following tests to check your urinary system for disease or injury:
Ultrasound. An ultrasound is an imaging test that allows your doctor to examine your interior organs. Ultrasounds are painless and require no preparation.
A computed tomography (CT) scan. A CT scan is an additional imaging exam. It's a sort of X-ray that uses cross-sectional images of your body, similar to slices, to create 3D views of the inside of your body. A CT scan is more exact than a regular X-ray.
Cystoscopy. A cystoscopy is a procedure that employs a cystoscope to view inside your bladder through your urethra. A cystoscope is a slender tool with a lens and a light on the end.
If you have UTIs on a regular basis, your doctor may order tests to look for other health problems, such as diabetes or an abnormal urinary system, that could be causing your infections.
Management & Treatment
What is the best treatment for a urinary tract infection?
The best way to treat a urinary tract infection is to visit a doctor. To treat a UTI, you'll need antibiotics. Your provider will choose an antibiotic that is most effective against the bacteria causing your infection.
Once you've been prescribed antibiotics, it's critical that you follow the instructions exactly. Even if your symptoms resolve and you begin to feel better, it is critical that you complete the entire antibiotic course. If you do not finish all of your medication, the infection may return and be more difficult to cure.
If you have UTIs frequently, a provider may prescribe that you take antibiotics.
Every day.
Every other day.
After sex.
At the initial appearance of symptoms.
If you have a history of frequent UTIs, consult with a clinician to determine the best treatment option.
What are the specific antibiotics used to treat a urinary tract infection?
Healthcare providers frequently prescribe the following antibiotics to treat UTIs:
Nitrofurantoin.
Sulfonamides (sulfa medicines), including sulfamethoxazole/trimethoprim.
Amoxicillin.
Cephalosporins, including cephalexin.
Doxycycline.
Fosfomycin.
Quinolones, include ciprofloxacin and levofloxacin.
If you have UTIs frequently, your doctor may prescribe low-dose antibiotics for a short period of time to keep the infection from recurring. The provider may advise you to take this cautious approach when treating frequent UTIs since your body can develop antibiotic resistance and you may contract additional infections, such as C. diff colitis. This is a relatively uncommon technique.
Can I develop immunity to the antibiotics used to treat a UTI?
Sort of. When you use antibiotics to treat a UTI, the infection adapts and becomes more difficult to treat (antibiotic resistance). However, the infection becomes resistant to the drugs, not you. Antibiotics may not always be the optimal solution. If you have repeated urinary tract infections, your healthcare provider may advise different therapies. This may include:
Waiting. Your doctor may recommend a "watch and wait" approach to your symptoms. During this period, you should consume plenty of fluids (particularly water) to assist flush your system.
Intravenous (IV) therapy. In some complex situations, a UTI may be resistant to drugs, or the infection may spread to your kidneys. You may require hospital treatment, in which case clinicians will administer medication via a needle inserted into a vein, typically in your arm. When you return home, you may need to take oral antibiotics for a while to fully recover from the infection.
Does cranberry juice help prevent a urinary tract infection?
Store-bought cranberry juice does not prevent a UTI. However, cranberry extract supplements (vitamin tablets) may reduce your risk of developing a UTI.

Minor urinary tract infections can sometimes resolve on their own. However, most UTIs require antibiotics to resolve. If you have a UTI, you definitely need antibiotics, as well as:
A fever.
Chills.
Nausea and vomiting.
How soon will I feel better following the treatment?
Most people feel better within a few days of taking antibiotics to treat a UTI.

What can I expect if I get a UTI?
The outlook for urinary tract infections is positive. Most UTIs respond favorably to therapy. A UTI can be bothersome or uncomfortable before you begin therapy. However, after a healthcare expert has identified the bacteria and prescribed the appropriate antibiotic, your symptoms should recover rapidly.
It is critical that you complete all antibiotics prescribed by your doctor. If you have frequent UTIs or your symptoms do not improve, your doctor may test to discover if your infection is resistant to antibiotics. Antibiotic-resistant illnesses may necessitate intravenous antibiotics or other therapies.

Can I prevent a urinary tract infection?
To help prevent urinary tract infections, make the following lifestyle changes:
Practice good hygiene.
Practicing excellent cleanliness is one of the most effective strategies to prevent UTIs. This is especially crucial if you have a vagina because your urethra is significantly shorter, making it simpler for E. coli to return from your rectum to your body. To avoid this, always wipe from front to back after having a bowel movement.
During your monthly cycle, you should also change your period products, such as pads and tampons, on a regular basis. You should also avoid applying deodorants to your vagina.
Drink lots of fluids.
Drinking plenty of fluids, particularly water, on a daily basis can help wash bacteria out of your urinary system. Healthcare providers advocate drinking six to eight glasses of water every day.
Change your urination habits.
Peeing can help remove bacteria from your body. Your pee is a waste product, and every time you empty your bladder, you help your body eliminate that waste.
Peeing frequently can lower your risk of contracting an infection, especially if you have UTIs frequently.
You should also try to pee just before and after having sex. Sex can introduce bacteria into your urethra, and peeing before and after sex helps wash them out. If you are unable to urinate, bathe the region with warm water.
Change your birth control.
If you use a diaphragm for birth control, you may be more likely to develop a UTI. Consult a healthcare provider about additional birth control methods.
Apply a water-based lubrication during intercourse.
If you use lubricant during sex, it should be water-based. If you have frequent UTIs, you should avoid using spermicides.
Change your clothes.
Tight-fitting garments can produce a wet environment that encourages bacterial growth. To keep moisture away from your urethra, try wearing loose-fitting clothing and cotton underwear.
Medications
If you are postmenopausal, your healthcare physician may recommend an estrogen-containing vaginal cream. These lotions may lower your chance of acquiring a UTI by altering the pH of your vagina. If you are postmenopausal and have a lot of UTIs, speak with your doctor.
Over-the-counter (OTC) supplements like cranberry extract and probiotics may also help prevent UTIs. Consult your doctor before beginning any supplement regimen.
