Signs And Symptoms Of Bladder And Kidney Infection

The infection of the bladder is also called cystitis. These infections usually affect the urethra, the thin tube that carries urine. The symptoms of cystitis are; more frequent and painful urination, urination at night(nocturia), foul smell of urine, and sometimes blood in the urine. In some cases, mild fever can also occur.

Bladder infections occur more commonly in women. It is because of their anatomy. Due to shorter urethra compared to males, females are more likely to get bladder infections. Escherichia coli or other bacteria entering the bladder through the urethra usually cause bladder infections. Bladder infections are less complicated than kidney infections. However, that does not mean they are not serious.

An untreated bladder infection can lead to a kidney infection. It is more complicated than a bladder infection as it involves all the symptoms seen in bladder infection along with more of its own, like acute or chronic abdominal or lower back pain, high-grade fever, chills, nausea, and upset stomach. The patient might be having more frequent urination or less urination. Kidney infection, if left untreated, can lead to sepsis. Therefore, it is necessary to get timely treatment.

Treatment For Kidney And Bladder Infections

Treatment for kidney and bladder infections typically involves antibiotics. For mild bladder infections, your doctor may recommend an over-the-counter antibiotic or a single dose of it. For severe bladder infections, a longer course of antibiotics may be prescribed.

Kidney infections are more severe and may require hospitalization and intravenous antibiotics. In some cases, surgery may be necessary to get rid of the infection, and any scarring that has occurred. It is necessary to seek medical attention for any of these infections as soon as possible to reduce the risk of complications.

Diagnosis Of Kidney Infection And Bladder Infection

The diagnosis of kidney and bladder infections typically involves a physical exam and a urine sample to check for bacteria and other signs of infection. Blood tests may also be ordered to check for an elevated white blood cell count and other signs of infection.

An ultrasound or CT scan may also be used to check for any structural abnormalities or blockages in the urinary tract. These processes may be slightly different for kidney infections compared to bladder infections depending on the severity of the infection.
