There are many reasons for high specific gravity of urine, which can be seen in infection or diabetes, concentrated urine or dehydration in the body, and other phenomena, which need to be further combined with their own symptoms to decide whether treatment is needed: 1. If you drink less water, sweat more, and have insufficient fluid volume replenishment, you are often seen with an increased specific gravity of urine, especially in the hot summer months. At this time, there is usually no stinging pain in urination or increased frequency of urination, back pain, fever and other symptoms, and only proper hydration is required, resulting in a decrease in the specific gravity of urine. 2. When a urinary tract infection occurs, it will also manifest as an increase in the specific gravity of urine due to the presence of more bacterial components in the urine. If there is a high number of white blood cells and bacteria, accompanied by urinary frequency, urinary urgency, urinary tract irritation symptoms, it is recommended to carry out anti-infection treatment, after the infection heals, the urine specific gravity can be restored to normal. 3, if there are endocrine system diseases, such as diabetes, tuberculosis, etc. can cause the specific gravity of urine to rise, you need to actively control internal diseases, such as stabilization of blood sugar or treatment of tuberculosis and other primary diseases. 4. Patients with kidney disease, which contain more protein in the urine, can also cause the specific gravity of urine to increase; accompanied by a series of complications such as hyperuricemia and hypoalbuminemia. It is necessary to actively treat the primary diseases of the kidney, and the specific gravity of urine can return to normal after the kidney function gradually improves.
