Healthy adults typically urinate four to seven times each day, according to Healthgrades. Certain health conditions may cause people to urinate 10 to 30 times daily. Someone who goes eight times or more a day or two to three times at night should see a doctor.
Causes of excessive urination range from minor to more significant conditions. Interstitial cystitis and overactive bladder are among the more common and treatable conditions, reports Healthgrades. An enlarged prostate, urinary tract infections and anxiety may also cause frequent urination. Pregnant women and people taking diuretics also tend to urinate more often than normal. In some cases, excessive urination is a habit.
