Water intoxication

A condition that is caused by excessive water retention in the brain. The principal symptoms are headaches, dizziness, nausea, confusion, and, in severe cases, seizures and unconsciousness. Various disorders can disrupt the water balance in the body, leading to accumulation of water in the tissues. Examples include kidney failure, liver cirrhosis, severe heart failure, diseases of the adrenal glands, and certain lung or ovarian tumours producing a substance similar to ADH (antidiuretic hormone). Water intoxication is also seen in association with the use of Ecstasy (MDMA), during which excessive amounts of water are drunk. There is also a risk of water intoxication after surgery, caused by increased ADH production.
