Polyuria

 

increased formation of urine—in adults, more than 1,800 to 2,000 milliliters in 24 hours. Polyuria is caused by decreased reabsorption of water in the kidney tubules. The specific gravity of the urine is generally sharply decreased. Polyuria may be a symptom of kidney disease or disease of the endocrine glands and may result from treatment with diuretics. Temporary polyuria may be observed upon ingestion of a large quantity of beer or other liquids or may be a symptom of certain paroxysmal diseases, such as paroxysmal tachycardia and hypertensive and diencephalic crises.
