Urinary frequency refers to the frequent passing of urine, more than what is the norm for a person. Most of us pass urine anywhere between 3 to 6 times a day, sometimes more frequently. A sudden increase in the number of times you pass urine, especially if you have to wake up at night to urinate is known as urinary frequency. It is a sign of some underlying problem that needs to be treated in order for your urinating habits to return to normal.
