URINE

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.

FREQUENT URINATION

Experience has taught us that human machine requires three meals per day to do its work properly, and nature has provided for the elimination of the waste product at periodic intervals. The amount of urine which an ordinary bladder holds when the desire to urinate is first felt is about eight ounces. A normal person will void his urine during the day about every four or five hours, and as a rule a person can sleep at night for eight hours without voiding.

The frequency of voiding the urine depends upon:

1. the amount of urine excreted by the kidneys.
2. the capacity of the bladder.
3. the sensitiveness of the bladder.

KIDNEYS AND THE HUMAN BODIES

Each human being is made up of billions of cells working 24 hours a day., producing toxic wastes which circualte through the blood. Causing it to become somewhat polluted. It would take very little time for the accumulation of these wastes to intoxicate the human body and death by poisoning could result. Fortunately, the kidneys are there to filter the blood-they remove toxins from the blood, eliminating them from the body in the form of urine. withoutkidneys, one would not survive the inevitable "blood pollution"

when kidneys stop functioning:

Various diseases can attact our kidneys, reduce their effectiveness and renal insufficiency would result. As the kidneys lose their filtering ability, the toxic waste accumilate in the blood and eventually when their lavel becomes sufficiently elevated, symptomps such as fatigue, lost of appetite and nausea appear. Ultimately, uremia, which is the accumulation of one of these wastes in the blood (urea), could kill.

• Preventing kidney failure
  It might take a while for symptomps to appear, that is when ore than 75% of the kidneys have ceased functioning. with the help of blood and urine test, kidneys failure may be detected before the appearance of symptomps. It is therefore possible to find the cause of renal insufficiency, perhaps correct it and threby save the kidneys. However, even if a cure i not possible, treatment can always be undertaken to minimize the progression of renal insufficiency. Diabetes and hypertension are the two major causes of renalinsufficiency which can be prevented by controlling these two problems with a proper diet and when neede, the appropriate medication.
• Treating Kidney failure
  Medical research has resulted in the discovery of techniques which can cleanse the blood of these toxins when the kidneys have completely ceased functioning, dialysis under the form of hemodialysis or peritonal dialysis. Thanks to this techniques, iremia does not kill anymore. However, the most satisfying solution still remains kidney transplants. unfortunately, the number of donors is not by any means sufficient to meet the even increasing need for kidneys.
  

KIDNEYS ROLES TO OUR BODIES

Kidneys play many important roles:

• they control the production of red blood cells through the bone marrow, they help maintain a normal blood pressure,they control the quantity of water in the human body along with the adequate absorption of calcium and they are also necessary to build strong bones.without kidneys, anemia would result and our bones would break very easily. Moreover, kidneys act as the chemists of the body by maintaining the precise chemical composition of the blood.
• Once again, medical research has discovered means of replacing the kidneys in all their functions should they fail.For this reason, kidney patients require a lot of medication along with dialysis treatments. from the avobe, one can fully realize the importance of healthy kidneys as well as medical research; it allows for a better quality of life for those who have lost the use of their kidneys.
