The bladder is located in your pelvis. It is a muscular organ that functions to store and expel urine. Urine drains from the kidneys via the ureters into the bladder. It is then stored until it reaches a point where it signals you that you need to urinate. The bladder then contracts and passes the urine out via the urethra. The urethra and bladder are therefore part of the lower urinary tract while the ureters and kidneys are part of the upper urinary tract. Bladder infections is also known as cystitis.
Most bladder infections are due to bacteria, but it can also be due to yeast or viral infections and sometimes chemical irritation. Bladder infection can either be complicated (due to factors such as stones, urethral strictures, prostate enlargement, and more that increases the risk of infection and lowers the effectiveness of antibiotic therapy) or uncomplicated (infection in a normal urinary tract, both structurally and functionally).
Symptom #1: Dysuria
Dysuria refers to pain during urination, a burning sensation, or discomfort that occurs most commonly due to a bladder infection caused by bacteria. It is usually accompanied by other symptoms of urinary tract infection such as blood in the urine. It can occur in women after intercourse when infection is present.
There are other causes of dysuria such as pyelonephritis (kidney infection), prostatitis (infection of the prostate), or due to sexually transmitted diseases. If you are experiencing prolonged dysuria, it is best to seek medical attention as the infection could spread upwards to the kidneys and cause more severe symptoms.
