Sodium (Na) regulates the water and acid-base balance and affects the excitability of nerve cells and muscle contractility. Find out when your blood sodium level biochemical test is ordered and what could be the reason why your sodium levels are too high or too low.

Sodiumis the predominant component of the extracellular fluid. A constantsodium levelis maintained through the action of kidney hormones and the regulation of sodium and water excretion from the body. A biochemical test to assess the level of sodium in the body is performed when there is a risk of dehydration or fluid overload. In addition, it allows you to determine whether the disturbances in sodium metabolism are not the cause of diseases or disorders of the brain, heart, liver, kidneys, thyroid gland or adrenal glands.

Sodium: Lab Standard

Sodium norm - 135-145 mmol / l

Increase in sodium concentration: causes

Increased sodium levels can be caused by dehydration, excessive kidney water loss, excessive skin water loss through sweating, and gastrointestinal water loss through diarrhea. Failure and nephrotic syndrome, right heart failure, hyperthyroidism and deficiency of vasopressin - a hormone that regulates the level of body hydration also contribute to the increase in sodium concentration.

Sodium drop: causes

A decrease in sodium concentration may be caused by the excessive excretion of sodium through the kidneys, skin (burns or sweating) and through the digestive system as a result of vomiting and diarrhea. Hyperhydration may also contribute to the decrease in sodium concentration - increased parenteral fluid intake in the body (i.e. a large amount of fluid in the body not related to watering, but resulting from pathogenic or pathogenic factors), reduced water excretion, deficiency of cortisol - the adrenal cortical hormone .
