What is Bladder Infection?


Bladder infection, also known as cystitis, is caused by abnormal bacterial growth within the bladder, a balloon-like organ that secures urine. Bladder infections are the most common bacterial infection affecting humans, with one-third of women having at least one infection at some point in their lives.

Bladder infections are considered simple or complicated. Common bladder infections affect only healthy women with a normal urinary system. Bladder infection is rare in men who are otherwise healthy, so the male is included in a complex type that includes members of both sexes who have an unusual urinary system.

  • Simple bladder infection. When bacteria move into the bladder, simple bladder infections occur. Due to the structure of the female urinary system, women are more likely to catch these diseases than men. In women, it is closer to the rectum for the urinary tract (where the urine comes). Therefore, bacteria can migrate from the rectum, where the bacterial count is high, in the area around the vagina and urine. From there, there is a short journey (4 cm, or less than 2 inches) from the urinary tract to the bladder. Sexual intercourse can cause these bacteria to enter the bladder, thus increasing the risk of bladder infection in sexually active women. Cleansing the toilet tissue from the back to the front of the intestine can also move the bacteria into the renal tract. For this reason, women should always try to wipe from front to back.
  • Complicated bladder infections. Bladder infections are classified as complex when they affect people with an abnormal urinary system, which makes the infection difficult to treat. When affecting the male, all bladder infections are considered complex, as long male urinary tract infections should prevent bacteria from entering the bladder. However, if there is a normal flow of urine or if urine in the bladder persists, the bacteria will multiply there, increasing the risk of infection. One of the causes of urinary retention in the bladder is neurological damage, either from an injury, such as a spinal cord injury or by a disease such as diabetes. The most common cause of obstruction of urine flow in men is an enlarged prostate, which is common in men over the age of 50. Patients with urinary catheters (a tube inserted into the urethra for urinary tract) also have a higher rate of bladder infection as the bacteria grow. Along the bladder catheter wall.


Simple bladder infection

An infection of the bladder causes inflammation (inflammation and inflammation) of the bladder and urine. It causes the sudden development of an expected set of symptoms. Many women who have had a bladder infection in the past can easily identify the symptoms when they develop an infection. These symptoms usually include one or more grade:

  • The need to urinate more often than usual, though only a small amount of urine passes each time.
  • The need to urinate suddenly
  • Pain, irritation or other discomforts during urination
  • Need to pee at night
  • Pain in the lower abdomen
  • Blood in the urine
  • The urine, which is cloudy, has a pleasant smell or its aroma is unusual

New bedside episodes may be the only symptom caused by a bladder infection in a young child.

Complex bladder infection

People with complex bladder infections usually have common symptoms like simple infections, however, patients may develop additional symptoms such as fever, cold, nausea, vomiting, acute pain, back pain, or confusion if the bacteria. The urinary tract circulates to the bloodstream or kidney.

Complicated bladder infections require longer treatment than simple infections. Further tests may also be needed to see the structure or function of the urinary system.


Your doctor will ask you for symptoms that are specific to the bladder infection, and will also ask if you have a fever, chills, nausea, vomiting, stroke pain, or other symptoms. Which can suggest a more serious infection? If you have had a bladder infection before, your doctor may diagnose this problem over the phone if you are not pregnant and due to vaginal discharge. If the symptoms are not the same as the infection in the first bladder, you will probably need to go to the office and possibly urinate.

For the first time, women with bladder infections, all men, children and anyone with any potentially complicated bladder infection will need to see a doctor. Your doctor will examine you and request a urine sample. He will analyze urine in the office to find signs of active infection. The urine sample can also be sent to the Culture for Laboratory to identify the correct type of bacteria. Special tests, commonly called sensitivity testing, also determine which antibiotics will effectively fight the infection. Before providing a urine sample, clean your urinary tract with a sterile cleanse. It is important to collect this urine during urine in order to avoid urinary tract bacteria that live in the vicinity of the disease.

Expected duration

Women with a common bladder infection often improve within hours of taking the first dose of antibiotics, and all symptoms should go away within three days. However, people with complex infections, such as men with enlarged prostate glands, can be a long symptom. If patients have catheters in place, it is difficult to clean the bacterial urinary system until the catheter is removed.


Women can help prevent bladder infection by wiping back and forth with toilet tissue and after having sexual intercourse. Some women who have two or more bladder infections each year take antibiotics three times per week, or daily, to prevent infection. Other steps that can help prevent bladder infection include going to the bathroom as soon as you feel urination and drinking plenty of fluids daily. Some women who use a diaphragm for contraception, reduce the bladder repeatedly by switching to different methods to prevent pregnancy. Some studies suggest that drinking cranberry juice may lower your risk of urinary tract infection.


Depending on the nature of the problem, treatment varies:

Simple bladder infection
In women, bladder infections are usually treated with a three-day course of an antibiotic, such as tri methaprim sulfamethoxazole (bacterium, Septra, co-trimoxazole). Women with recurrent bladder infections (more than two every year) may benefit from preventative antibiotics, whether taken as a regular dose or after intercourse.

Complex bladder infection
Complicated bladder infections are more difficult to treat. Depending on the circumstances, the choice of antibiotic, the strength of the drug and the length of treatment vary. Often, antibiotics need to be taken for 10 days or longer. Patients with acute symptoms (fever, confusion, nausea, vomiting, etc.) who suggest that the bacteria have spread to the kidney or blood will usually need to be treated at the hospital.

When to Call a Professional

If you feel pain or discomfort while urinating, if you need to urinate more than usual, or if you find that your urine is stinking or has blood in it, see your doctor. Call the office at Women in the first trimester of pregnancy should undergo urine testing for bacterial development as part of prenatal care even if there is no sign of a bladder infection.

If you have risk factors for a complicated bladder infection (such as a catheter at home or a primary defect in the urinary system), you should be especially careful to look for these signs of infection. If you develop a fever, cold, confusion, nausea, vomiting, or acute pain, you should also seek immediate medical attention, which may suggest that a bladder infection has spread to the kidney or blood.


Treatment with antibiotics usually cures simple bladder infections. In some cases, an untreated bladder infection can spread upstream in the urinary tract to infect the kidneys, resulting in pyelonephritis, which is a kidney inflammation and infection. For complex bladder infections, the outlook depends on the clinical situation. Patients can become seriously ill if the infection spreads from the urinary system to the bloodstream, a condition known as euros. Antibiotic antibiotics are usually effective. Generally, patients diagnosed with Eurosepsis require a longer course of antibiotics, but this can be accomplished at home with antibiotics that are taken by mouth.
