Treatment of Overhydration
Restriction of fluid intake Treatment of the cause of overhydration Regardless of the cause of overhydration, fluid intake usually must be restricted (but only as advised by doctors). Restricting drinking to less than a quart of fluids (about 0.9 liters) a day usually results in improvement over several days. If overhydration occurs with excess blood volume because of heart, liver, or kidney disease, restricting the intake of sodium is also helpful because sodium causes the body to retain water. Drugs that tend to cause overhydration are stopped. Sometimes, doctors prescribe diuretics (drugs that increase the excretion of sodium and water in the urine). Other types of drugs also can increase water excretion and are sometimes used to treat overhydration when blood volume is normal. These drugs are generally used when a person is in the hospital and can be carefully monitored.
