Syndrome of inappropriate antidiuretic hormone secretion

Description

A condition in which high levels of a hormone cause the body to retain water.

Overview

In this condition, high levels of the anti-diuretic hormone (ADH) are produced, causing the body to retain water instead of passing it through the urine. ADH is also known as vasopressin hormone. This upsets the body's balance of minerals and electrolytes, especially sodium.

Symptoms

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

Treatments

Treatments include limiting fluid intake and, possibly, medicines to adjust the electrolyte balance. Underlying conditions also need treatment.
