A low specific gravity of urine indicates that there may be a decrease in water reabsorption by the glomerulus and tubules, resulting in an increase in urine, so that the specific gravity of urine will be significantly reduced, and it is seen in the polyuric phase of renal failure. It may also be due to the amount of urine formed as a result of drinking too much water in general, which can lead to low specific gravity of urine. Low urine specific gravity must be evaluated together with the presence of other symptoms in the body, and you cannot determine what the disease is simply by low urine specific gravity. The most common diseases are uremia and polyuria in renal failure, which are also very easy to diagnose. In the case of renal failure, it has oliguria and only through treatment does it have polyuria. It is recommended that for all diseases, the specific problem must be analyzed.
