URINE
Low specific gravity of urine may be merely a temporary condition, the result of drinking large quantities of water or other liquids shortly before voiding the sample of urine submitted for examination. when more water is taken than the system requires, the excess is promptly excreted by the kidneys. the habit of drinking water freely may be beneficial for some persons, but it is not advisable as a steady practice. It throws extra work upon the heart and kidneys.the chemical and microscopic examination of urine of low specific gravity is not a fair test of condition of the kidneys.. Therefore, if you have been notified that a sample you submitted for laboratory examination had low specific gravity, an additional specimen should be taken. by restriction of liquids or water for several hours before voiding, your urine will become more concentrated and usually show a higher specific gravity.Persistent low specific gravity of the urine, not due to excessive water drinking, is not a normal condition and usually indicates a chronic form of kidney trouble or hardening of the arteries which occurs usually in very old people. such a condition should be investigated by your physician in order to determine the exact cause.
