Sodium (+) Sodium plays a critical role in helping your cells maintain the right balance of fluid. The following section includes the major elements, marked as positive (+) or negative (-), and what happens when there’s too much or too little of that element. These include staying hydrated, reducing your salt intake and exercising. The normal range for blood sodium levels is 135 to 145 milliequivalents per liter (mEq/L). There are several key elements that your body needs to maintain normal electrolyte levels. There are a number of ways to reduce sodium levels in your blood. Symptoms of high sodium levels in the blood can include: A rare condition called diabetes insipidus, which affects the body’s ability to process water.Dehydration, from diarrhoea and vomiting or diuretics (usually water tablets given for high blood pressure) A normal level of sodium in your blood is between 135 and 145 milliequivalents per liter (mEQ/L), which measures how much sodium is available to interact with other molecules in your blood, allowing it to effectively regulate your water levels.Hypernatremia is defined as a serum sodium level above 146 mmol/L. Hypernatremia Symptoms and causes of hypernatremia In more extreme cases a saline (salt) solution may be administered intravenously to gradually raise sodium levels to a safe level. Sodium Sample type: Serum Test name: Sodium Condition / Indication: Electrolytes Special precautions & notes: Part of electrolyte profile Reference range. Treatment for hyponatremia will depend on the underlying cause and may be as simple as adjusting your diet, drinking less water or stopping taking certain medications until sodium levels are restored. In really serious instances, low sodium levels can cause the brain to swell leading to confusion, fits, comas and sometimes death, though this is rare. This usually happens if you drink too much water in a short time. Low sodium levels in the blood causes hyponatremia. But higher levels of sodium in the blood that don’t come down, do need further investigation. If you’re otherwise feeling well, it’s quite possible the test result was due to poor sample collection or a reflection of your sodium level on that day, and the next reading may be normal. 146 mmol/L or above (hypernatremia) is much less common. A high level of sodium in the blood, i.e. Some people naturally have slightly high sodium levels, usually around 146-148 mmol/L.Ī low level of sodium in the blood (also known as hyponatremia) is relatively common. The normal concentration of sodium in the blood plasma is 136-145 mM. The normal range for sodium levels in the blood is 135-145 millimoles per litre (mmol/L). Hypernatremia is defined as a serum sodium level over 145 mM. Your body carefully balances the sodium levels in the blood.
