Passing larger amounts of urine than usual.

Self-care includes keeping a daily record of fluid intake, how much urination and how often, and weight.

See a healthcare professional if:

• Passing a lot of urine that's not linked with drinking a lot of fluid or taking medicines that cause your body to make more urine, such as water pills.
• Passing more than 3 quarts (3 liters) of urine a day.
