If a woman urinates less and more often, it is recommended to go to the hospital for further examination to clarify the possible causes. The reasons for this are as follows: 1. If an infection occurs in the urinary system, the patient will experience significant urinary frequency, an increase in the number of urinations accompanied by a decrease in urine volume, and may experience burning pain in the urethra each time she urinates, and in severe cases, she may even have fever, abdominal pain, and back pain. It is necessary to take urine for routine urine examination and urine culture test to further determine whether there is urinary tract infection.2. If there are stones in the urinary system, such as bladder stones or ureteral stones, there will be obvious symptoms of urinary tract irritation. Symptoms such as frequent and urgent urination, painful urination or pain in the lower back and abdomen appear. The volume of urination is relatively low because of increased bladder sensitivity. Ultrasound examination of the urinary system is recommended to rule out the presence of bladder stones and ureteral stones.
