Low Urine Specific Gravity In Urinalysis: What Does It Mean?

The normal range for urine specific gravity is between 1.005 and 1.030. Occasionally, drinking large amounts of water can cause the urine specific gravity to drop below 1.005. If the low specific gravity is simply due to increased fluid intake, it is considered normal and does not require any treatment.

However, certain medical conditions can also lead to consistently low urine specific gravity. For example, kidney failure or a decline in the kidneys' ability to concentrate urine may result in persistently low readings. In such cases, medical attention and treatment are necessary. Additionally, endocrine disorders like diabetes insipidus can cause low specific gravity due to a deficiency in antidiuretic hormone (ADH).

Accurate diagnosis requires a comprehensive evaluation, including urinalysis and imaging tests such as a urinary system ultrasound. These diagnostic tools help identify the underlying cause so that appropriate treatment can be determined based on the individual patient's condition. If low urine specific gravity is observed repeatedly, it is important to consult with a healthcare provider to rule out any serious health issues.
