Frequent urination of small amounts of urine associated with pain and discomfort, are symptoms of urinary tract infection.
Frequent needs to urinate, urinating large amounts of urine with excessive thirst, may indicate uncontrolled diabetes.
If the frequent urination is accompanied with sudden urge to pass urine and experiencing an involuntary loss of urine immediately following the urgent need to urinate, you may have an overactive bladder.
Finally, frequent urination can be a normal reaction of drinking excessive amounts of liquids.
