If you have a medical condition that increases your risk of hyponatremia or you take diuretic medications, be aware of the signs and symptoms of low blood sodium.
Why does my body lose sodium?
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.
What causes sodium to be lowered?
Heart, kidney and liver problems. 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. Syndrome of inappropriate anti-diuretic hormone (SIADH).
Does low sodium cause hyponatremia?
A number of studies have associated low serum sodium levels with increased mortality in various patient populations, such as hospitalized patients and patients with various comorbid conditions; recent studies have shown that individuals with chronic kidney disease also are afflicted by hyponatremia.
Is hyponatremia a chronic disease?

Why is hyponatremia important?
Hyponatremia is a frequently encountered problem in clinical practice and is an important cause of morbidity and mortality. Establishment of etiology and appropriate treatment improves outcome. A knowledge of recent guidelines of treatment and the appropriate use of vaptans is essential for all clinicians for proper diagnosis and management.
What is the normal response to hyponatremia?
The normal response to hyponatremia is marked suppression of ADH secretion, resulting in the excretion of a maximally dilute urine with an osmolality below 100 mosmol/kg and a specific gravity ≤1.003. Values above this level indicate an inability to normally excrete free water, most commonly because of persistent secretion of ADH.
Why do marathon runners have hyponatremia?
Marathon runners may develop severe hyponatremia due to excessive water intake associated with persistent ADH secretion in some. [ 24, 25]
How much NaCl is needed for hyponatremia?
Patients need administration of sodium chloride to correct the volume deficit, 3% normal saline is not indicated. K may be added if required. 0.9%NaCl corrects the hyponatremia by two mechanisms: It slowly raises the serum sodium by approximately 1 meq/L for every liter of fluid infused since 0.9%NaCl has a higher sodium concentration (154meq/L) than the hyponatremic plasma and by correcting the hypovolemia, it removes the stimulus to ADH release
What is considered a chronic hyponatremia?
Chronic hyponatremia- Hyponatremia developing over > 48 h should be considered “chronic.” Most patients have chronic hyponatremia. The serum sodium concentration is usually above 120meq/L. Brain adapts itself to hyponatremia by generation of idiogenic osmoles. This is a protective mechanism that reduces the degree of cerebral edema; it begins on the first day and is complete within several days. Hence in chronic hyponatremia patients may appear asymptomatic. Mild hyponatremia is characterized by gastrointestinal tract symptoms nausea, vomiting, loss of appetite. Sometimes, subtle neurologic abnormalities may be present when the serum sodium is between 120 and 130 meq/L. Hyponatremia in the elderly may manifest with frequent falls and gait disturbances. [ 3]
What is the onset of symptoms of hyponatremia?
Acute hyponatremia is characterized by onset of symptoms <48h. Patients with acute hyponatremia develop neurologic symptoms resulting from cerebral edema induced by water movement into the brain. These may include seizures, impaired mental status or coma and death.
What causes hypovolemic hyponatremia?
Mineralocorticoid deficiency is another important cause of hypovolemic hyponatremia and may be associated with hyperkalemia.
Why is hypernatremia rare?
Hypernatremia is rare. It occurs when a person doesn’t get enough water, either because of limited access to water or an impaired thirst mechanism. It’s caused less commonly by diabetes insipidus. It occurs when your serum sodium level exceeds 145 mEq/L.
What happens if your sodium levels drop?
If they drop very quickly, your symptoms may be more severe. Losing sodium quickly is a medical emergency. It can cause loss of consciousness, seizures, and coma. Common symptoms of low blood sodium include: weakness. fatigue or low energy.
What does it mean when your sodium is low?
The results of this test will help your doctor determine the cause of your low blood sodium: If your blood sodium levels are low but your urine sodium levels are high, your body is losing too much sodium. Low sodium levels in both your blood and your urine mean your body isn’t taking in enough sodium. There may also be too much water in your body.
What is the sodium level in your blood?
In other words, there’s either too much water or not enough sodium in your blood. Normally, your sodium level should be between 135 and 145 milliequivalents per liter.
How to prevent low sodium levels?
Prevention of low blood sodium. Keeping your water and electrolyte levels in balance can help prevent low blood sodium. If you’re an athlete, it’s important to drink the right amount of water during exercise. You should also consider drinking rehydration beverages like Gatorade or Powerade.
Why is sodium important?
Sodium is an essential electrolyte that helps maintain the balance of water in and around your cells. It’s important for proper muscle and nerve function. It also helps maintain stable blood pressure levels. Insufficient sodium in your blood is also known as hyponatremia. It occurs when water and sodium are out of balance.
How to treat low sodium?
It may include: cutting back on fluid intake. adjusting the dosage of diuretics. taking medications for symptoms such as headaches, nausea, and seizures. treating underlying conditions.
What happens if your sodium is low?
When blood sodium is very low, it may result in coma or extended unconsciousness. Other symptoms that may be associated with low blood sodium include tiredness, loss of appetite, nausea, vomiting, headaches, muscle weakness and cramps. Advertisement.
How does sodium affect the body?
The concentration of sodium in the blood changes depending on the conditions affecting the body. When blood sodium is low, aldosterone -- a steriod hormone produced by the adrenal glands -- is released to act in the kidneys; in the kidneys, aldosterone increases sodium reabsorption, which results in the elevation of blood sodium. The intake of dietary sodium also helps restore normal sodium levels. When sodium is increased in the blood, blood volume and pressure also increase; as a result, more blood is filtered and more urine produced.
Why is urine more concentrated?
The urine may also be analyzed for its composition; the urine is more concentrated when kidney function is reduced. Since increased sodium excretion by the kidneys can result in low blood sodium, examination of the urine for sodium concentration may be helpful as well. Advertisement.
Why is sodium important in the body?
In the body, more sodium is outside the cells than inside, because the cell membranes are not freely permeable. Low levels of blood sodium can result in decreased kidney function, and larger losses of sodium can result in kidney failure.
Why is blood flow important in the kidneys?
Oxygen is transported via the blood; therefore, blood flow must be maintained to ensure adequate oxygen supply to the kidneys. The pumping of the heart results in blood flow, but without adequate blood volume, the effectiveness of the heart will be compromised.
Does sodium increase blood pressure?
The intake of dietary sodium also helps restore normal sodium levels. When sodium is increased in the blood, blood volume and pressure also increase; as a result, more blood is filtered and more urine produced. Advertisement.
What is true hyponatremia?
Box 1. “True” hyponatremia occurs when the serum osmolality or tonicity is decreased. For this defect to occur, there has to be some inability of the body to excrete free water through the kidneys despite continued water intake. This can occur in the following 3 settings (Table 1). Table 1.
What is the sodium level of hyponatremia?
Hyponatremia is typically defined as a serum sodium concentration of less than 134 mmol/L. In the past, hyponatremia was often diagnosed erroneously when the patient had high levels of serum lipids or plasma proteins.
What hormone is released when ECF is enlarged?
With ECF volume contraction from any cause (diarrhea, vomiting, excessive sweating, diuretic use), the release of antidiuretic hormone ( ADH) is stimulated to defend ECF volume; this makes the kidney's distal tubules more permeable to water reabsorption.
How to treat hyponatremia in patients with hypervolemia?
The management of hyponatremia in patients with hypervolemia can be difficult. Water restriction to less than 1.25 L/d is essential . Sodium restriction to 70 mmol/d (with the aid of a dietitian) will help with edema. A loop diuretic should be used to promote sodium and water excretion by the kidneys. In both congestive heart failure and cirrhosis, the addition of a potassium-sparing diuretic is useful to prevent hypokalemia and lessen edema (and ascites). Referral to a cardiologist or hepatologist may be necessary in cases of refractory heart failure or cirrhotic ascites. Patients with nephrotic syndrome should be referred to a nephrologist, as specific therapies (e.g., with corticosteroids and immunosuppressive drugs) may be directed at the cause of their disease and reduce proteinuria.
What causes SIADH in box 2?
The many causes of SIADH (Box 2) include almost any pulmonary or neurologic problem. Some lung cancers can produce ectopic ADH, which signals inappropriately to the kidney. Numerous medications can have an ADH-like effect on the renal tubules or potentiate the effect of endogenous ADH: some of the more common agents are presented in Box 3. Other stimuli include pain and excessive nausea and vomiting.11,12,13,14
How to manage hyponatremia?
The key to effective management of hyponatremia is establishing the type and its cause, so that the cause can be removed, if possible, and the management will be appropriate. Paramount is clarifying whether the hyponatremia has developed quickly (over a few days) and is acute or whether it has developed over days to weeks and is chronic. The rapidity of correction of the serum sodium concentration should be closely linked to the suspected time over which the hyponatremia has developed.
Why do you need potassium in a diuretic?
In both congestive heart failure and cirrhosis, the addition of a potassium-sparing diuretic is useful to prevent hypokalemia and lessen edema (and ascites). Referral to a cardiologist or hepatologist may be necessary in cases of refractory heart failure or cirrhotic ascites.
