Osmotic Diuresis Overview
What is an osmotic diuresis?
A person with osmotic diuresis makes more urine than usual. Osmotic diuresis is caused by the presence of large molecules that enter the kidneys from the bloodstream. The molecules draw water from the bloodstream, and into the urine. Common causes of osmotic diuresis include hyperglycemia and drug side effects. Dehydration is the most common complication of osmotic diuresis.
What are the symptoms of an osmotic diuresis?
Osmotic diuresis does not cause symptoms unless dehydration occurs. Symptoms of dehydration include faintness, dizziness, rapid pulse, and dry mouth.
How does the doctor treat an osmotic diuresis?
Treatment of an osmotic diuresis depends on the underlying cause. In most cases, an osmotic diuresis does not require treatment. Oral fluids or intravenous fluids may be necessary if dehydration occurs.
