Blood sodium level test. what is the norm?

Testing your blood sodium level is one of the key laboratory tests that help monitor your health. Sodium plays an important role in the proper functioning of the body, so its concentration should be maintained within appropriate limits. In this article, we will discuss what sodium is, its role in the body, how to prepare for a blood sodium level test, and what the norms are for different age groups. In addition, you will learn the causes and symptoms of hyponatremia (too low sodium level) and hypernatremia (too high sodium level) and how to ensure proper sodium concentration in the body.

What is sodium?

Sodium is a chemical element that plays a key role in regulating blood pressure, water and electrolyte balance and the functioning of nerve and muscle cells. It is necessary to maintain the appropriate pH of the body and participates in nerve conduction.

The role of sodium in the proper functioning of the body

Sodium works with potassium to maintain the body’s water and electrolyte balance. It regulates the amount of fluid inside and outside cells, which affects blood volume and blood pressure. Additionally, sodium is involved in the conduction of nerve impulses and muscle contractions, which is necessary for the proper functioning of the heart, muscles and nervous system.

Blood sodium level test. how to prepare for the test?

A blood sodium test is often performed during routine blood tests, but may also be ordered to monitor a patient’s health. There are no special preparation requirements before the test, but it is important to inform your doctor about any medications you take, dietary supplements and any medical conditions you may have. The test result will be available a few days after blood collection.

Sodium – the norm for women, men and children in test results

Blood sodium levels may vary slightly from laboratory to laboratory, but the general rule is that normal sodium levels are between 135 and 145 mmol/L. For children, these standards may be slightly higher. Low or high sodium levels can indicate health problems, so it’s important to monitor them and consult your doctor if you have any concerns.

Hyponatremia – causes and symptoms of low sodium levels in the body

Hyponatremia is a condition in which the level of sodium in the blood is too low. It may be the result of excessive fluid loss, malnutrition, kidney disease or excessive water consumption. Symptoms of hyponatremia may include nausea, vomiting, headache, confusion, seizures and behavioral changes. In severe cases, it may lead to coma.

Hypernatremia – causes and symptoms of too high sodium levels in the body

Hypernatremia is a condition in which the level of sodium in the blood is too high. It may be caused by dehydration, excessive salt consumption, diabetes, hyperthyroidism or abnormal kidney function. Symptoms of hypernatremia may include thirst, dry mouth, increase in blood pressure, confusion, seizures and loss of consciousness.

How to ensure proper sodium concentration?

To maintain the appropriate sodium concentration in the blood, it is important to maintain the body’s water and electrolyte balance. You should avoid excessive salt intake, maintain moderate fluid intake and monitor your health regularly. If symptoms of hyponatremia or hypernatremia occur, immediate medical consultation is necessary.
