High urine specific gravity means that the urine specific gravity is greater than 1.030. High urine specific gravity indicates a significant increase in metabolites in the urine, and you should pay attention to whether there is an increase in red blood cells and white blood cells, an increase in urine sugar, an increase in urine bilirubin and urinary bilirubin, and an increase in the content of organic and inorganic salts in the urine, etc. You should make a comprehensive assessment and then decide how to deal with it. The most common cause of increased urine specific gravity may be a lack of water intake and concentration of urine, or it may be a urinary tract infection that causes an increase in urine specific gravity, which will certainly increase when there are a large number of red blood cells and white blood cells in the urine after a urinary tract infection. At the same time, pay attention to the possibility of urinary tract tuberculosis, urinary tract tumor, it is recommended to do ultrasound examination of the kidney, ureter and bladder, which can clarify further diagnosis and treatment.
