Neurologist Ekaterina Demianovskaya has told news outlet RIAMO that urinating in the shower does not lead to incontinence or bladder disease.
Addressing common concerns about urinary health, Demianovskaya explained that there is no convincing scientific evidence showing that emptying the bladder while taking a shower damages the urinary tract or weakens muscle control.
In healthy human anatomy, urination is a complex reflex mechanism governed by the central nervous system, the bladder, and pelvic floor muscles. The pelvic floor supports the pelvic organs, while nerve signals coordinate muscle contractions to release or retain urine.
Psychological habits and urinary urges
According to Demianovskaya, while regular shower urination poses no physical danger to the bladder, the practice can establish a psychological habit. Repeatedly relieving oneself during a shower can train the nervous system to pair the sound of running water with the urge to urinate.
Demianovskaya cautioned against visiting the bathroom as a precaution when no urge is present. She explained that habitual preemptive urination reduces the working capacity of the bladder, causing the body to send urge signals at lower fluid volumes.
She added that individuals should also avoid delaying bathroom visits until experiencing severe physical discomfort, as extreme holding can place unnecessary strain on the urinary system.
Demianovskaya shared her clinical assessment with RIAMO, a Russian regional news agency based in the Moscow region that regularly reports on public health matters.
Incontinence and underlying health conditions
The discussion around incontinence follows earlier observations by urologist Jason Carter and colorectal surgeon Ketan Tanki, who identified fecal incontinence as an underreported symptom of bowel cancer.
Bowel cancer, also known as colorectal cancer, affects the large intestine and is among the most frequently diagnosed cancers worldwide. Medical specialists note that changes in bowel control warrant clinical evaluation, though patients often avoid reporting them due to social stigma.
Carter and Tanki emphasized that loss of bowel control is a critical sign of bowel disease that is rarely discussed by either patients or doctors during health consultations.
