1 Urinary tract infection Bladder has metabolic function, which can excrete water and waste stored in bladder in time. Because there are many bacteria in urine, the concentration of bacteria in urine will increase, thus reducing the immune function of bladder and allowing a large number of bacteria to invade and cause urinary tract infection.

2 nerve damage Habitual urination can cause abdominal pain, urinary incontinence and frequent urination. Because excessive compression of the bladder will make the micturition nerve in an excited state, urine will suddenly be discharged after micturition, and the nervous system will also be in an excited state. It makes people feel like they can't finish urinating.

3 renal failure The kidney is a fragile organ of the human body and can excrete urine. If you urinate frequently and can't excrete urine in time, your heart will always be excited and damage your internal organs. In addition, urine stays in the kidneys and urethra for a long time, which will cause bacterial infection and cause diseases such as pyelonephritis or renal failure.

4 Prostatitis urine stays in the bladder for too long, and the urine is pressed to the surface of the bladder wall, and bacteria are easy to invade, leading to cystitis. Urine stays in the prostate tube, and the prostate will cause infection of toxic substances, which will lead to prostatitis.
