Common symptoms of an enlarged bladder include slow urine flow, always feeling like the bladder is full and difficulty urinating, notes MedlinePlus. People with this condition may also experience abdominal pain. In some cases, people with enlarged bladders may become incontinent, notes Sharecare. This occurs when urine builds up enough that the bladder cannot hold it all and it leaks out.
If the enlarged bladder is severe enough, the kidneys can fail, according to MedlinePlus. People whose condition gets to this point may begin to experience nausea and fatigue, as well as general fluid retention. Enlarged bladders can also cause pain during urination, and the person may have to use the bathroom frequently without producing much urine each time. Patients may also develop urinary tract infections.
An enlarged bladder is itself often a symptom of another condition, according to MedlinePlus. It is commonly caused by a blockage in the urinary tract which prevents the bladder from emptying normally. This is usually treated by using a catheter to remove the blockage and drain the bladder. Enlarged prostates in men can cause these symptoms, and in women it can be caused by the bladder dropping into the vagina, or cystocele. It can also be caused by bladder tumors and other cancer in the area.
