Disease description:

I’m generally a carefree person and have always enjoyed good health. Recently, however, I’ve constantly felt weak and fatigued, and I’ve been sweating excessively. I went to the hospital for a check-up, and the results showed that my urine specific gravity was elevated. What could cause an increased urine specific gravity?

In healthy individuals, an elevated urine specific gravity can be classified as either physiological or pathological. It indicates concentrated urine and may fluctuate significantly due to factors such as insufficient fluid intake, excessive sweating or urination, high fever, cardiac insufficiency, or diabetes mellitus. It is recommended that you promptly visit the nephrology department of a reputable hospital for evaluation and consultation. A specialist will perform appropriate diagnostic tests to establish a definitive diagnosis and initiate targeted treatment. In daily life, ensure adequate rest and maintain a light, bland diet.
