Bladder infection

Bladder Infection

A bladder infection, also known as a urinary tract infection (UTI), is a type of infection that affects part of the urinary system. The urinary system includes the kidneys, bladder, ureters, and urethra. Bladder infections are often caused by bacteria that enter the urethra and then the bladder.

Causes

Bladder infections are typically caused by Escherichia coli (E. coli), a type of bacteria commonly found in the gastrointestinal (GI) tract. However, sometimes other bacteria are responsible. Sexual intercourse may lead to bladder infections, but you don't have to be sexually active to develop one. All people, of all ages, can get bladder infections.

Symptoms

Symptoms of a bladder infection can include:

• Pain or a burning sensation during urination
• A frequent urge to urinate
• Cloudy, dark, bloody, or strong-smelling urine
• Lower abdominal pain
• Low-grade fever

Diagnosis

A bladder infection is usually diagnosed by a healthcare provider based on symptoms and a laboratory test of a urine sample. The urine sample can show white blood cells, red blood cells, bacteria, and other substances that can indicate an infection.

Treatment

Treatment for a bladder infection typically involves antibiotics to kill the bacteria causing the infection. It's important to take the full course of antibiotics, even if symptoms improve before the medication is finished. Drinking plenty of water can also help flush bacteria out of the urinary system.

Prevention

Prevention strategies for bladder infections can include drinking plenty of fluids, urinating regularly, and for women, urinating shortly after sexual intercourse.
