Frequent urination

Frequent urination may happen when there's a problem with part of the urinary tract. The urinary tract is made up of the kidneys; the tubes that connect the kidneys to the bladder, which are called the ureters; the bladder; and the tube where urine exits the body, called the urethra.

You may pass urine more often than usual because of:

1. Infection, disease, injury or irritation of the bladder.
2. A condition that causes your body to make more urine.
3. Changes in muscles, nerves or other tissues that affect how the bladder works.
4. Certain cancer treatments.
5. Things you drink or medicines you take that cause your body to make more urine.

Frequent urination often happens along with other urinary signs and symptoms, such as:

1. Feeling pain or discomfort when you pass urine.
2. Having a strong urge to pass urine.
3. Having trouble passing urine.
4. Leaking urine.
5. Passing urine that's an unusual color.
