Urinary tract infection is a common infection causing pain and a burning sensation while urinating. It refers to an infection in any part of the urinary system caused by microorganisms.
Most UTIs are caused by bacteria, but even fungi and viruses are responsible for the infection. Urinary tract infections can affect both men and women, but women are more prone to develop UTIs than men.
When the infection involves the urethra, it is called urethritis. When it affects the kidneys, it is called pyelonephritis, which is called cystitis when infecting the bladder.
Most of the time, UTIs will affect only the urethra and the bladder and become more painful and annoying if they are confined to the bladder. But when it spreads to the kidneys, the problem may become more severe.
Antibiotics may help treat urinary tract infections, but it is also necessary to follow prevention steps to help lower the chance of getting a UTI.
Causes of Urinary Tract Infections
- Bacteria: UTIs are most commonly caused by bacteria, particularly Escherichia coli (E. coli), which is found in the gut.
- Sexual activity: Due to the close proximity of the urethra to the anus and the introduction of bacteria during sexual activity, there is an increased risk of UTIs, especially in women.
- Pregnancy: Changes in hormones and the physical pressure of the growing uterus on the bladder and urinary tract can increase the likelihood of UTIs during pregnancy.
- Urinary catheterization: The use of urinary catheters to drain the bladder may increase the risk of UTIs, as they provide a direct pathway for bacteria to enter the urinary tract.
- Immune system issues: Diabetes and HIV/AIDS are two immune-system-affecting disease disorders that can make UTIs more likely.
- Personal hygiene: Poor hygiene habits, such as wiping from back to front after using the loo, might raise the risk of UTIs by introducing bacteria into the urinary system.
Below mentioned are some of the most common reasons that lead to the increased development of UTIs:
- Difficulty in emptying the bladder
- Diabetes
- If you used a catheter recently
- If diagnosed previously with UTI
- Being sexually active
- Blockage in the urinary tract due to kidney stones or other conditions
- Having vesicoureteral reflux, a condition that causes a backward flow of urine from the bladder and up toward the kidneys
- Poor hygiene habits
The following bacteria are mainly responsible for causing UTIs:
- Escherichia Coli or E-coli
- Proteus Mirabilis
- Enterococcus Faecalis
- Staphylococcus saprophyticus
- Klebsiella Pneumoniae
Who Are Affected By Urinary Tract Infections?
UTIs may affect people irrespective of age and sex, but some people have higher chances of developing the problems than others.
- Males, pregnant people, people with lower immunity levels, older people, people using catheters, and those with radiotherapy treatment are at higher risk of developing UTIs.
- Women can face this problem more than once in their lifetime. This is due to the female urethra's shorter length and closer proximity to the anus, which is where E. coli bacteria are frequently found.
- Older adults are at an increased risk of getting UTIs (mainly cystitis). This condition in older adults is prevalent due to the incomplete emptying of the bladder.
- Babies and young children are also at a higher risk of getting UTIs.
Symptoms Of Urinary Tract Infection
Redness and irritation in the lining of the urinary tract are general symptoms of urinary tract infections. The symptoms include:
- Pain in the abdomen, pelvic region, or flanks
- Pressure in the lower pelvis
- Frequent urination, the urge to urinate, and incontinence or urine leakage
- Painful urination or burning sensation while urination (dysuria) or bleeding during urination (haematuria)
- Need for peeing more often at night than usual (nocturia)
- Cloudy or darker urine with a strong smell
- A high temperature, or feeling extremely hot and also shivering
- A low temperature below 36 degrees Centigrade
Other symptoms associated with UTIs are:
- Fatigue
- Pain in the flank (side portion of the body)
- Pain in the lower back
- Fever and chills
- Vomiting
- Changes in mood or confusion
In children, the symptoms are as follows:
- High temperature - a child may feel hotter than usual, particularly when touched near their neck, back, or tummy areas
- Feels generally not well - babies and young children think irritable and don’t want to eat and be fed well
- Bedwetting and wetting themselves
- Feels sick
In older people or people with urinary catheters, the UTI symptoms may be as follows:
- Changes in their behaviour, like acting distressed or confused (delirium)
- Wetting themselves (incontinence) than usual
- Shivering and shaking
Diagnosis Of Urinary Tract Infections (UTI):
The following tests may be conducted to diagnose urinary tract infections:
- Urinalysis examines the urine for red blood cells, white blood cells, and bacteria. The number of RBCs and WBCs found in the urine will determine the infection of the urinary tract
- Urine culture helps detect the bacteria present in the urine, which helps determine the proper treatment for UTIs. If the treatment does not cure the infection and recurs over time, the following tests are needed to examine the urinary tract for underlying disease or injury.
- Ultrasounds produce images of the internal organs created by sound waves. The test is done on the skin.
- Cystoscopy is a special instrument fitted with a lens and a light source that is used to see inside the bladder from the urethra.
- A CT Scan is a kind of X-ray that takes cross-sections of the body and is much more accurate than general X-rays.
Treatment of Urinary Tract Infections
General physicians would suggest antibiotics to treat UTIs.
It is essential to follow the tips provided by the healthcare providers and not stop the antibiotics in between if the symptoms are reduced.
Prevention Of Urinary Tract Infections
- Maintaining Good Hygiene: UTIs can be prevented by practising good personal hygiene. It is significant for women, as the urethra is smaller than men, and E.coli bacteria can move from the rectum and back to the body. Women must develop good hygiene habits during the menstrual cycle to avoid infections.
- Drinking Plenty Of Fluids: Drinking lots of fluids, especially water, can help remove bacteria from the urinary tract. Having 6 to 8 glasses of water per day is generally recommended.
- Changing Urination Habits: As urination plays a vital role in flushing bacteria from the body, urinating frequently will help reduce the risk of UTIs. Fluids and foods that irritate the bladder have to be avoided. Cleaning the genitals with warm water before intercourse and urinating after intercourse is a good practice to prevent infections.
- Changing Birth Control Methods: The use of a diaphragm by women for birth control may increase the risk of UTIs in them. So, it is better to change to other options for birth control.
- Changing Outfits: It is better to avoid tight-fitting dresses. This helps prevent the growth of bacteria in the urinary tract. The other ways to stop recurrent UTIs are:
- Wash hands thoroughly before and after touching the genitals
- Avoiding spermicides
- Wiping from front to back
- Use vaginal estrogens
Conclusion
UTIs will occur due to the bacteria that infect the urinary system and can be cured using antibiotics. Drinking fluids and maintaining good hygiene habits will help reduce urinary tract infections.
Don’t ignore the symptoms, as they can be quite painful and hamper your lifestyle. Contact our Urinary tract infection(uti) doctors at Max Hospital and fix your appointment immediately.
