Syndrome of inappropriate antidiuretic hormone secretion

Overview

In this condition, the body retains water instead of excreting it normally in urine. This process upsets the body's balance of minerals called electrolytes, especially sodium.

Symptoms

Symptoms include nausea and vomiting, headache, confusion, weakness, and fatigue.

Treatments

Treatments include fluid restriction and, possibly, medications to adjust electrolyte balance. Underlying conditions also need treatment.
