If an elderly woman has frequent urination at night, it is recommended to go to the hospital for further examination to clarify the cause and then treat the symptoms. Possible causes are as follows: 1. Chronic urinary tract infections, when patients often have a feeling of incomplete urination and symptoms such as frequent and urgent urination. Ultrasound of the urinary system and tests such as routine urine and urine culture are needed. If the infection is clearly present, anti-infection treatment is recommended. The medication can be based on the results of the urine culture drug sensitivity test to select a sensitive antibiotic for treatment. You can also take levofloxacin hydrochloride capsules orally, 1 capsule once, 3 times a day for 3-5 days, and observe whether the symptoms improve; 2. Decreased bladder function, the elderly may be accompanied by bladder prolapse or weak contraction of the bladder forcing muscle. This leads to more residual urine in the patient, and therefore produces frequent urination movements. Ultrasound is recommended to determine the residual urine. If the residual urine is greater than 50 ml or more, it is recommended to take oral flavone permethrin tablets, one tablet once, three times a day, and to give an indwelling catheter if necessary. If there is severe bladder prolapse, surgery is needed if necessary. 3. If the elderly have diabetes mellitus or coronary heart disease, etc., frequent nighttime urination may occur, which is not caused by the urinary system, and further examination of heart function and blood sugar level is needed. If there is an associated medical pathology, a physician will need to be consulted for collaborative management.
