A urine specific gravity of 1.025 is considered normal. Urine specific gravity is generally the ratio of the weight between the same volume of urine and the same volume of pure water. Normal human urine specific gravity is 1.003~1.035, and urine specific gravity 1.025 is within the range, so urine specific gravity 1.025 belongs to normal urine specific gravity. Urine specific gravity reflects the concentration function of the renal tubules, if the tubular concentration function is good, the urine specific gravity will be relatively high. If the renal tubular function is impaired, such as acute interstitial nephritis, chronic interstitial nephritis, the urine specific gravity will be reduced. In addition, protein, sugar, minerals, contrast media, etc., may increase the specific gravity of urine; and patients who drink too much water, or the application of diuretic drugs, may make the specific gravity of urine low. In conclusion, urine specific gravity of 1.025 belongs to the normal range, generally do not need to worry too much, if there are uncomfortable symptoms, it is recommended to consult a doctor in time.
