Urine specific gravity value of 1.030 may be due to low water intake, glomerulonephritis, diabetes mellitus and other reasons. Urine specific gravity between 1.010~1.025 is the normal range. If it is greater than 1.025, you need to find out the reason, you can drink more water in daily life, or follow the doctor’s prescription for appropriate medication. 1. Low water intake: patients with low water intake, due to low intake of water leading to a decrease in glomerular filtration rate, urine concentration, there will be a specific gravity of urine increased to 1.030 phenomenon. You can drink more water to dilute the urine, which can relieve the phenomenon. 2. Glomerulonephritis: when the patient suffers from glomerulonephritis disease will also be due to the lack of blood flow in the kidneys, resulting in increased urinary protein in the urine, triggered by increased specific gravity of urine, can be prescribed by the use of diuretics, such as furosemide tablets, or the use of anti-inflammatory drugs such as ciprofloxacin tablets. 3. Diabetes mellitus: Due to the elevated level of glucose in the urine, the specific gravity of urine will be increased to 1.030. Patients should follow the doctor’s instructions to give hypoglycemic drugs for oral treatment, such as metformin or insulin injections to lower sugar, can relieve the symptoms. Urine specific gravity of 1.030 patients can also be seen in other reasons, need to strictly comply with the doctor’s instructions for examination and standardized treatment, so as to avoid delaying the condition.
