Cystitis is the medical term used to describe inflammation of the bladder. Inflammation occurs when a part of your body becomes swollen, heated, and often painful, indicating that the body is responding to irritation or infection.
In the majority of cases, cystitis is triggered by a bacterial infection, leading to what’s commonly known as a urinary tract infection (UTI). A bladder infection can be incredibly uncomfortable and disruptive to daily life. Furthermore, it’s crucial to address cystitis promptly as the infection can escalate and spread to the kidneys, potentially causing more severe health issues.
However, bacterial infections aren’t the only cause of cystitis. This condition can also arise as a reaction to certain medications, radiation therapy, or irritants like specific hygiene products, spermicides, or prolonged use of urinary catheters. In some instances, cystitis can even develop as a secondary complication of another underlying illness.
Fortunately, bacterial cystitis is typically treated effectively with antibiotics. For other forms of cystitis, the treatment approach will depend on identifying and addressing the root cause of the inflammation.
Recognizing the Symptoms of Cystitis
The signs and symptoms of cystitis can vary from person to person, but commonly include:
- Persistent and Intense Urge to Urinate: A feeling that you constantly need to urinate, even immediately after emptying your bladder.
- Pain or Burning Sensation During Urination (Dysuria): Discomfort or a stinging feeling as urine passes through the urethra.
- Frequent Urination of Small Amounts (Frequency): Needing to urinate much more often than usual, but only passing a small volume of urine each time.
- Hematuria (Blood in the Urine): Urine may appear pink, red, or brownish due to the presence of blood.
- Cloudy or Strong-Smelling Urine: Urine may look murky or have an unusually pungent odor.
- Pelvic Discomfort: A general feeling of ache, pressure, or pain in the pelvic region.
- Lower Abdominal Pressure: A sensation of fullness or pressure in the area just below the belly button.
- Low-Grade Fever: A slightly elevated body temperature may sometimes accompany cystitis.
In young children, a sudden onset of daytime wetting accidents, when they are typically toilet-trained, can be an indicator of a UTI and potentially cystitis. It’s important to note that nighttime bed-wetting alone is less likely to be a symptom of a UTI.
When to Seek Medical Attention for Cystitis Symptoms
It’s essential to seek prompt medical attention if you experience symptoms that could suggest a kidney infection, as this is a more serious condition. These symptoms include:
- Pain in the Back or Side (Flank Pain): Pain felt in your back or along your side, below the ribs.
- Fever and Chills: A high temperature accompanied by shivering.
- Nausea and Vomiting: Feeling sick to your stomach and throwing up.
If you develop persistent and bothersome urinary symptoms such as urgency, frequency, or pain lasting for several hours, or if you notice blood in your urine, it’s crucial to contact your healthcare provider. If you have a history of UTIs and your current symptoms are similar to previous infections, reaching out to your provider is also recommended.
Furthermore, if cystitis symptoms return after completing a course of antibiotics, it’s important to consult your healthcare provider again. You may require a different type of medication to effectively treat the infection.
For children experiencing new daytime wetting accidents, a consultation with their pediatrician is advised.
Cystitis is uncommon in otherwise healthy men. Therefore, any urinary symptoms in men should be evaluated by a healthcare professional to determine the underlying cause.
Understanding the Causes of Cystitis
To understand cystitis, it’s helpful to know about the urinary system. This system, responsible for removing waste from the body through urine, comprises the kidneys, ureters, bladder, and urethra.
The kidneys, bean-shaped organs located in the upper abdomen towards your back, filter waste and excess fluid from the blood to produce urine. This urine then travels from the kidneys to the bladder through narrow tubes called ureters. The bladder serves as a storage sac for urine until you are ready to urinate, at which point the urine exits the body through another small tube called the urethra.
Bacterial Cystitis: The Most Common Cause
Urinary tract infections (UTIs), and consequently bacterial cystitis, typically occur when bacteria from outside the body enter the urinary tract through the urethra and begin to multiply within the bladder. The most frequent culprit behind bacterial cystitis is Escherichia coli (E. coli), a type of bacteria commonly found in the gastrointestinal tract. However, other types of bacteria can also cause bladder infections.
In women, bacterial bladder infections can sometimes be associated with sexual activity, as intercourse can introduce bacteria into the urethra. However, UTIs can occur in women who are not sexually active as well. This is because the female genital area can naturally harbor bacteria that can ascend into the urinary tract and trigger cystitis.
Non-Infectious Cystitis: Other Contributing Factors
While bacterial infections are the predominant cause of cystitis, several non-infectious factors can also lead to bladder inflammation. These include:
- Interstitial Cystitis (Painful Bladder Syndrome): This chronic condition involves bladder inflammation, and its exact cause remains unclear. It is more prevalent in women and can be challenging to diagnose and manage effectively.
- Drug-Induced Cystitis: Certain medications, particularly some chemotherapy drugs used in cancer treatment, can cause bladder inflammation as the body processes and eliminates drug byproducts.
- Radiation Cystitis: Radiation therapy directed at the pelvic area can induce inflammatory changes in bladder tissues as a side effect.
- Foreign Body Cystitis: Prolonged use of urinary catheters can increase the risk of both bacterial infections and physical irritation of the bladder lining, both of which can lead to inflammation.
- Chemical Cystitis: Some individuals exhibit heightened sensitivity to chemicals found in certain personal care products such as bubble baths, feminine hygiene sprays, or spermicidal jellies. Exposure to these chemicals can trigger an allergic-type reaction within the bladder, resulting in inflammation.
- Cystitis Associated with Other Medical Conditions: In some cases, cystitis can develop as a complication of pre-existing health conditions, such as diabetes, kidney stones, an enlarged prostate gland in men, or spinal cord injuries.
Risk Factors for Developing Cystitis
Certain factors can increase an individual’s susceptibility to developing bladder infections or recurrent UTIs. Women, in particular, are more prone to bladder infections due to anatomical reasons. The female urethra is shorter than the male urethra, meaning bacteria have a shorter distance to travel to reach the bladder and cause infection.
Specific risk factors for bladder infections and recurrent UTIs include:
- Sexual Activity: Sexual intercourse can introduce bacteria into the urethra, increasing the risk of infection.
- Certain Types of Contraception: Diaphragm use is associated with an elevated risk of UTIs. Diaphragms used with spermicidal jelly may further increase this risk.
- Pregnancy: Hormonal shifts during pregnancy can alter the urinary tract and increase the likelihood of bladder infections.
- Menopause: Hormonal changes following menopause often contribute to an increased risk of UTIs in women.
Other factors that can elevate the risk of cystitis include:
- Obstruction of Urine Flow: Conditions that impede the normal flow of urine, such as bladder stones or an enlarged prostate, can increase infection risk.
- Compromised Immune System: Conditions that weaken the immune system, like diabetes, HIV infection, and cancer treatments, can make individuals more susceptible to infections, including cystitis.
- Long-Term Urinary Catheter Use: Individuals requiring long-term urinary catheters, such as those with chronic illnesses or older adults, are at a higher risk of bacterial infections and bladder tissue damage.
As mentioned earlier, cystitis is relatively uncommon in generally healthy men.
Potential Complications of Untreated Cystitis
When promptly and appropriately treated with medication, bladder infections rarely lead to complications. However, if left untreated, cystitis can progress and result in more serious health issues, including:
-
Kidney Infection (Pyelonephritis): An untreated bladder infection can ascend to the kidneys, causing a kidney infection, also known as pyelonephritis. Kidney infections are more severe and can potentially lead to permanent kidney damage.
-
Hematuria (Blood in the Urine): Cystitis can cause blood to appear in the urine. In some cases, this may be microscopic hematuria, where blood cells are only visible under a microscope and typically resolves with treatment. However, persistent microscopic hematuria after treatment may warrant further investigation by a specialist to determine the underlying cause.
Gross hematuria, or visible blood in the urine, is less common with typical bacterial cystitis. However, it may be more frequent in cases of cystitis resulting from chemotherapy or radiation therapy for cancer.
Prevention Strategies for Cystitis
While robust scientific evidence supporting self-care measures to prevent recurrent bladder infections is limited, healthcare providers often recommend the following preventative tips:
- Stay Well-Hydrated: Drink plenty of fluids, especially water, throughout the day. Adequate hydration is particularly important after chemotherapy or radiation therapy, especially on treatment days.
- Urinate Frequently and When the Urge Arises: Avoid holding urine for extended periods. When you feel the need to urinate, use the restroom promptly.
- Practice Proper Wiping Technique: After a bowel movement, always wipe from front to back to prevent bacteria from the anal region from spreading to the vagina and urethra.
- Consider Showers Instead of Baths: If you are prone to infections, showering may be preferable to taking tub baths, as baths can potentially increase exposure to bacteria.
- Gentle Genital Hygiene: Wash the skin around the genitals daily with mild soap and water. Avoid harsh soaps or vigorous scrubbing, as this can irritate the delicate skin in this area.
- Urinate After Sexual Intercourse: Empty your bladder as soon as possible after sex to help flush out any bacteria that may have entered the urethra. Drinking a full glass of water can also aid in this process.
- Avoid Irritating Feminine Products: Refrain from using deodorant sprays, douches, and other potentially irritating hygiene products in the genital area, as these can irritate the urethra and bladder.
The Role of Cranberry in Cystitis Prevention
Cranberry juice and cranberry supplements containing proanthocyanidins are frequently suggested as natural remedies to reduce the risk of recurrent bladder infections. While research in this area is ongoing and sometimes yields mixed results, some evidence suggests that cranberry products may help prevent recurrent UTIs in certain individuals.
Cranberry products are generally considered safe for healthy individuals without underlying medical conditions.
However, as a home remedy, caution is advised with cranberry juice or cranberry products if you are taking the blood-thinning medication warfarin (Coumadin). There is a potential, though debated, interaction between cranberry and warfarin that could increase the risk of bleeding.
It’s important to note that cranberry has not been proven to be an effective treatment for an existing bladder infection. If you suspect you have cystitis, consulting a healthcare professional for appropriate diagnosis and treatment is always recommended.
