Whether an increase in urine specific gravity is dangerous depends largely on the cause of the increase. If the increase is physiologic, it is usually not dangerous; if it is pathologic, the primary disease is more serious and has not been actively and effectively treated, it may be more dangerous.
1. Physiologic increase: mostly caused by drinking too little water or sweating too much. A simple increase in urine specific gravity is usually not dangerous and is a normal phenomenon.
2. Pathologic increase: common in acute glomerulonephritis, nephrotic syndrome, diabetes mellitus and so on.
(1) Acute glomerulonephritis, nephrotic syndrome: the patient’s urine contains more protein, resulting in increased specific gravity of urine, if the specific gravity of urine continues to increase, the patient may have renal function damage, as well as increased risk of thrombosis, or even renal failure, which is a more dangerous situation.
(2) Diabetes mellitus: Patients may also experience increased urine specific gravity due to the increased concentration of solutes in the urine. If the patient does not carry out rehydration therapy to control blood sugar, it may be life-threatening, which is more dangerous at this time.
If the patient found that the specific gravity of urine increases, it is recommended to go to the regular hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or treatment under the guidance of the doctor.
