Diabetes Insipidus vs. SIADH: Know the Difference
By Shumaila Saeed || Published on February 19, 2024
Diabetes Insipidus is a condition causing excessive urination and thirst due to hormone imbalance, whereas SIADH (Syndrome of Inappropriate Antidiuretic Hormone) involves excessive retention of water caused by abnormal hormone secretion.
Key Differences
Diabetes Insipidus results from a deficiency of the antidiuretic hormone (ADH) or its response, leading to excessive urine production. In contrast, SIADH involves excessive release or action of ADH, leading to water retention and dilution of blood.

Major symptoms of Diabetes Insipidus include intense thirst and large volumes of urine. SIADH presents with fluid retention, leading to weight gain, swelling, and in severe cases, brain swelling. Diagnosis of both conditions involves blood and urine tests, focusing on electrolyte levels and urine concentration.

Diabetes Insipidus can be caused by genetic factors, kidney issues, or damage to the pituitary gland. SIADH is often associated with lung disorders, brain injuries, or certain medications, reflecting a different set of underlying causes.

Treatment of Diabetes Insipidus may involve hormone replacement or medications to reduce urine output. SIADH treatment focuses on restricting fluid intake, correcting electrolyte imbalances, and addressing the underlying cause.
