The normal range for blood sodium levels is 135 to 145 milliequivalents per liter (meq/l). Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples.

• Drugs that make you urinate more (diuretics
• Some types of antidepressants
• Carbamazepine, an anti-seizure medication
• Underactive thyroid or adrenal glands

• Certain cancers, including lung cancer

Hyponatremia treatments may include changing a medication that affects your sodium level, treating the underlying disease, changing the amount of water you drink or changing the amount of salt in your diet.

Low blood sodium is common in older adults, especially those who are hospitalized or living in long-term care facilities. Signs and symptoms of hyponatremia can include altered personality, lethargy and confusion. Severe hyponatremia can cause seizures, coma and even death.

Hyponatremia is the most common electrolyte abnormality in hospitalized patients, and it increases the likelihood of a hospital death (1–5). Inpatient mortality rates as high as 50% or more have been reported for patients with serum sodium concentrations (sna) <120 meq/l (6–9.

Many diseases and medications can cause hyponatremia. Most people recover fully with their healthcare provider's help. Unless your provider tells you something different, let your thirst be your guide in terms of how much water you drink.

Severe hyponatremia (serum/plasma sodium <115 mmol/l), particularly of rapid onset, is associated with marked confusion, seizures and coma, without emergent treatment, severe hyponatremia can be fatal.

Congestive heart failure and certain diseases affecting the kidneys or liver can cause fluids to accumulate in your body, which dilutes the sodium in your body, lowering the overall level.

Chronic, severe vomiting or diarrhea and other causes of dehydration. This causes your body to lose electrolytes, such as sodium, and also increases adh levels. Drinking too much water. Drinking excessive amounts of water can cause low sodium by overwhelming the kidneys' ability to excrete water.

In acute hyponatremia, sodium levels drop rapidly — resulting in potentially dangerous effects, such as rapid brain swelling, which can result in a coma and death.

Drinking too much water. Drinking excessive amounts of water can cause low sodium by overwhelming the kidneys' ability to excrete water. Because you lose sodium through sweat, drinking too much water during endurance activities, such as marathons and triathlons, can also dilute the sodium content of your blood.

• Intravenous fluids. Your doctor may recommend IV sodium solution to slowly raise the sodium levels in your blood
• Medications. You may take medications to manage the signs and symptoms of hyponatremia, such as headaches, nausea and seizures

Any value below 135 meq/l is considered to be a low , a condition medically referred to as hyponatremia. As sodium levels drop to 125 meq/l, the situation becomes more serious. And when the sodium level drops to 115 meq/l or below, the situation is critical and requires immediate treatment.

Your doctor may recommend iv sodium solution to slowly raise the sodium levels in your blood. This requires a stay in the hospital for frequent monitoring of sodium levels as too rapid of a correction is dangerous.
