Abnormally low levels of sodium in the blood. This may be due to excessive salt loss in sweat, overtreatment with DIURETICS, ADDISON'S DISEASE, chronic diarrhoea, or to heart, liver or kidney diseases featuring severe OEDEMA. There is low blood pressure, a fast pulse, a reduction in blood volume, reduced secretion of urine (OLIGURIA), muscle cramps and cold, pale skin.

decreased sodium concentration in the blood (<135 mmol.L-1). In otherwise healthy people, causes include vomiting, diarrhoea and excessive sweating.
