Slow and weak urination in women may be caused by cystitis, or neurological damage, bladder prolapse and other factors. 1. Cystitis: a kind of urinary tract infection, if the condition is serious, it may cause weakness of the urethra muscle, which will easily lead to weak urination, thin urine flow, and slow urination. 2. Nervous system damage: when the nervous system is damaged, it may directly inhibit the contraction nerve of the bladder, thus causing weak bladder contraction, which will eventually cause urinary weakness. 3. Prolapsed bladder: It usually occurs in women, and mostly belongs to postpartum injury. When the degree of bladder prolapse is aggravated, it may affect the normal contraction of the bladder muscle, resulting in bladder weakness, so there will be urinary weakness and slow urination and other symptoms when urinating. Women who find slow and weak urine when urinating may also be caused by vaginitis, cervicitis and other factors. It is recommended to consult a doctor in time for treatment.
