Normal morning urine specific gravity is between 1.015 and 1.025. A high urine specific gravity of 1.03 can be caused by physiological factors such as drinking too little water or sweating too much, and can also be caused by pathologic factors such as acute glomerulonephritis and heart failure.
Urine specific gravity usually represents the concentration of urine, which is affected by tubular reabsorption and concentration, and varies with the amount of water, salts and organic matter in the urine, and is also affected by urinary proteins, urinary glucose, and cellular components in pathological conditions. Urine specific gravity can roughly reflect the concentration and dilution function of the kidney.
Increased urine specific gravity can be seen in physiological conditions such as drinking too little water, sweating more, etc., when no special treatment, pay attention to rest, increase fluid intake, regular review can be.
Pathological factors such as acute glomerulonephritis, epidemic hemorrhagic fever oliguria, severe damage to liver function, heart failure and other causes of insufficient renal perfusion, as well as more protein or glucose in the urine can also lead to an increase in the specific gravity of the urine, at this time need to comply with the doctor’s instructions to improve the relevant examinations, a clear diagnosis, targeted treatment.
Therefore, for patients with high specific gravity of urine, it is recommended to consult regular hospitals and standardize treatment under the guidance of physicians.
