The factors that can affect the amount of urine excreted everyday include the following:
1. Blood glucose level. Also known as hyperglycemia, high levels of sugar in the blood will trigger frequent urination.
2. Blood pressure. The kidneys act to regulate blood pressure in the body by increasing or decreasing the amount of urine produced.
3. Salt. A high salt diet causes fluid retention and subsequently increased urination.
4. Alcohol. Alcohol consumption reduces production of the hormone vasopressin responsible for re-absorption of water back into the blood stream. When this hormone is not being produced as normal, fluids freely fill up the bladder leading to frequent urination.
5. Exercise (sweating)
6. Temperature of the environment
7. Level of fluid intake.
