Overactive bladder is a bladder dysfunction disorder that is not life-threatening, but may lead to urinary incontinence and pain, seriously affecting patients’ quality of life. The specific cause of overactive bladder is still unclear, and is currently considered to be related to factors such as instability of the detrusor muscle, over-sensitivity of the voiding center, and abnormal transmission of bladder sensory nerves, etc. Patients often suffer from symptoms such as frequent urination, urinary urgency, increased nocturia, and urge incontinence, and in severe cases, there are symptoms of urge incontinence and pain, which are not life-threatening and may affect the quality of life of patients. When the symptoms are mild, they can be improved by bladder training, pelvic floor muscle training, and drinking less water. When symptoms are severe, they can be treated with medications such as tolterodine or solifenacin as directed by a doctor. Surgery such as bladder enlargement, cystectomy, and urinary diversion may be an option for patients for whom other treatment options are not effective. All the above medications need to be aware of the side effects and adverse reactions of the medications, please use the above medications under the supervision of your doctor. Surgery carries certain risks or may not meet psychological expectations, and should be chosen carefully with full knowledge of the pros and cons of surgery. If you have overactive bladder, please seek active treatment in a regular hospital.
