Cystitis
"Cystitis is a common but treatable condition. Early detection and appropriate treatment are essential to prevent complications and improve our patients' quality of life".

What cystitis is
Cystitis is an infection or inflammation of the urinary bladder that causes discomfort when urinating, a frequent need to go to the bathroom, and pain in the lower abdomen. In most cases, it is caused by the bacterium Escherichia coli and affects women much more often than men.
Although it usually resolves with simple treatment, it is advisable to consult a specialist when the symptoms are severe, recur over time, or are accompanied by fever or blood in the urine, as these may indicate a complication or a more serious infection.

Symptoms of cystitis
The most common symptoms of cystitis are:
Burning or pain during urination
Many people experience a stinging sensation or discomfort during urination.
Urinary frequency
The need to urinate frequently, but in small amounts. This symptom, known as pollakiuria, is one of the most common.
Constant feeling of wanting to urinate
Even after emptying the bladder, the feeling of urgency to urinate may persist.
Bloody urine
In some cases, the infection may cause blood to appear in the urine, which is seen as a change in the colour of the urine.
No fever
Unlike other urinary tract infections, cystitis usually occurs without fever.
Do you have any of these symptoms?
If you suspect that you have any of the above symptoms,
you should consult a medical specialist for a diagnosis.
Types of cystitis
- Acute cystitis is the most common form, characterised by sudden onset and intense symptoms.
- Recurrent cystitis, on the other hand, occurs in repeated episodes, often due to persistent predisposing factors or an underlying infection that has not completely resolved.
Causes of cystitis
The usual germs come from faeces (enterobacteria). The most common is Escherichia coli (E. coli). This bacterium is responsible for 85% of uncomplicated infections in sexually active women, 70% of uncomplicated adult infections and 50% of hospital infections.
After E. coli, the most common germs are: Proteus, Klebsiella, Enterobacter, Citrobacter, Pseudomona, Serratia, Staphylococcus streptococcus faecalis and especially Staphylococcus saprophyticus.
What are the risk factors for cystitis?
Socio-economic conditions: Poverty or limited access to medical services may increase the risk.
Hospital settings - prolonged hospital stays or the use of devices such as urinary catheters increase the likelihood of infection.
Abnormalities in the urinary tract - malformations or structural alterations may predispose to infection.
Kidney stones (lithiasis). Especially struvite stones, which promote infection and require specific treatment.
Use of barrier contraceptives, methods such as diaphragms increase the risk of infection up to four times.
Urinary obstruction - the most important risk factor, as it makes it difficult to expel bacteria and can damage the kidneys.
Diabetes. Increased glucose in the urine promotes bacterial growth.
Immunosuppression. A weakened immune system, whether due to illness or treatment, increases vulnerability.
Pregnancy: During pregnancy, women are more likely to develop urinary tract infections due to changes in the body that make it easier for bacteria to accumulate.
Sexual activity: In sexually active women, the risk can be up to 40 times higher.
How is cystitis diagnosed?
To be considered as cystitis, bacterial growth in urine culture must demonstrate significant bacteriuria.
Next, it is necessary to identify the anatomical location of the infection, using clinical symptoms and, if necessary, complementary examinations.
Finally, it is necessary to indicate whether it is a:
- Primoinfection or isolated infection
- Unresolved infection
- Recurrent infection
Treatment of cystitis depends on the underlying cause and severity of the infection, and can range from antibiotics to self-care measures and lifestyle changes.
Treatment for cystitis

Antibioticis treatment of cystitis
The standard treatment for bacterial cystitis is the administration of antibiotics. Physicians select the type of antibiotic based on the type of bacteria responsible for the infection and local bacterial resistance. Among the most commonly prescribed antibiotics are:
- Trimethoprim/Sulfamethoxazole: This is one of the most commonly used antibiotics to treat uncomplicated cystitis.
- Nitrofurantoin: Effective for the treatment of lower urinary tract infections, including cystitis.
- Fosfomycin: Often used in a single dose, which facilitates adherence to treatment.
- Fluoroquinolones: Reserved for more severe or complicated cases due to their resistance profile.
The duration of antibiotic treatment can vary from three to seven days in uncomplicated cases, and can be extended in more complex situations.
Self-care measures
In addition to medical treatment, there are several self-care measures that can help relieve the symptoms of cystitis and prevent recurrence:
- Adequate fluid intake: Drinking enough water can help flush bacteria from the urinary system.
- Personal hygiene: Maintaining good genital hygiene can prevent bacteria from entering the urethra.
- Frequent urination: Not holding urine for prolonged periods can reduce the risk of infection
- Proper clothing: Wearing cotton underwear and avoiding tight-fitting clothing can help keep the genital area dry and reduce the risk of infection.
