Ectopic ADH secretion - Symptom

Alternative Names

SIADH; Syndrome of inappropriate antidiuretic hormone secretion

Symptoms:

The abnormal release of ADH makes it harder for the body to remove water. Fluid builds up in the body. Low blood sodium levels (hyponatremia) can occur.

Often, there are no symptoms from low sodium levels. However, changes in mental status and even seizures may occur.
