ADH Deficiency: Causes, Symptoms, Diagnosis & Treatment

When dealing with ADH deficiency, a condition where the body lacks adequate antidiuretic hormone, leading to excessive urination and thirst. Also known as central diabetes insipidus, it disrupts normal water balance. The hormone involved, antidiuretic hormone (ADH), regulates water reabsorption in the kidneys, and its synthetic replacement desmopressin, mimics ADH to reduce urine output, are key players. Understanding ADH deficiency helps you see why water balance goes off‑track and why hormone therapy matters.

Key Aspects of ADH Deficiency

ADH deficiency encompasses the broader syndrome of central diabetes insipidus, which means the pituitary gland isn’t releasing enough vasopressin. Common causes include pituitary tumors, head trauma, genetic mutations, or postoperative damage. Each cause represents an attribute of the condition: *Cause* – pituitary tumor, trauma, surgery; *Effect* – reduced ADH release; *Result* – polyuria (large volumes of dilute urine) and polydipsia (excessive thirst). Diagnosis often relies on a water‑deprivation test that measures how urine concentration changes when fluid intake is limited. If the kidneys can’t concentrate urine, the test points to ADH deficiency rather than a renal problem. Treatment usually requires desmopressin, taken as a nasal spray, tablet, or injection, which directly replaces the missing hormone and restores normal urine output. Lifestyle tweaks like monitoring fluid intake, using a low‑salt diet, and tracking weight also support therapy.

Beyond medication, patients benefit from education about electrolyte balance. Since ADH helps the body retain water, its absence can lead to low sodium levels (hyponatremia) if fluids are over‑consumed. Regular blood tests guide adjustments in desmopressin dose and dietary recommendations. Some cases respond to thiazide diuretics, which paradoxically reduce urine volume by promoting mild dehydration that triggers whatever residual ADH is present. Pediatric patients need special attention because growth and development can be impacted by chronic dehydration. Early diagnosis and consistent hormone replacement are crucial for preserving kidney function and preventing long‑term complications.
