Hyponatremia High volume hyponatremia can occur from heart failure, liver failure, and kidney failure. Conditions that can lead to falsely low sodium measurements include high protein levels such as in multiple myeloma, high blood fat levels, and high blood sugar. Treatment is based on the underlying cause.

What Happens If You Don't Consume Enough Sodium Sodium Deficiency. You lose a little sodium every day when you sweat, but your diet provides enough sodium to replace the amount lost. It's possible to become deficient in sodium if you sweat too much, like when you over-exert yourself on a sweltering day. You can prevent sodium loss by drinking sports drinks that contain electrolytes.

Acute Kidney Injury 1 Chronic renal failure: A permanent partial loss of kidney function. 2  Diabetes and high blood pressure are the most common causes. 3  End stage renal disease (ESRD): Complete loss of kidney function, usually due to progressive chronic kidney disease.

- This can lead to high blood pressure, which can cause other problems. Too much sodium in the blood is a condition called hypernatremia. Too little sodium in the blood is a condition called hyponatremia. Hypernatremia can occur when you lose too many fluids, often from sweating too much, vomiting, or diarrhea.

- Hyponatremia occurs when the body contains too little sodium for the amount of fluid it contains. The body may have too much, too little, or a normal amount of fluid. In all cases, however, sodium is diluted. For example, people with severe vomiting or diarrhea lose sodium.

Overview Chronic, severe vomiting or diarrhea. This causes your body to lose fluids and electrolytes, such as sodium. Drinking too much water. Because you lose sodium through sweat, drinking too much water during endurance activities, such as marathons and triathlons, can dilute the sodium content of your blood.

Low Blood Sodium (Hyponatremia) Many factors can cause low blood sodium. Sodium levels may get too low if your body is losing too much water and electrolytes. It may also be a symptom of certain medical conditions. Causes of low sodium include:

Health Risks and Disease Related to Salt and Sodium In most people, the kidneys have trouble keeping up with the excess sodium in the bloodstream. As sodium accumulates, the body holds onto water to dilute the sodium. This increases both the amount of fluid surrounding cells and the volume of blood in the bloodstream. Increased blood volume means more work for the heart and more pressure on blood vessels.

Low Blood Sodium (Hyponatremia) If blood sodium levels are low but urine levels are high, your body is losing too much sodium. Low sodium levels in both blood and urine mean your body is not taking in enough sodium. There may also be too much water in your body.

Common Lab Values And Test Result Meaning A low level of blood sodium (hyponatremia) may be due to: Losing too much sodium, most commonly from conditions such as diarrhea, vomiting, excessive sweating, use of diuretics, kidney disease or low levels of cortisol, aldosterone and sex hormones (Addison disease)

Low Blood Sodium (Hyponatremia) Causes of Low Sodium in Blood. Many factors can cause low blood sodium. Sodium levels may get too low if your body is losing too much water and electrolytes. It may also be a symptom of certain medical conditions. Causes of low sodium include:

Sodium: How to tame your salt habit Such diseases as congestive heart failure, cirrhosis and chronic kidney disease can make it hard for your kidneys to keep sodium levels balanced. Some people's bodies are more sensitive to the effects of sodium than are others. If you're sodium sensitive, you retain sodium more easily, leading to fluid retention and increased blood pressure.

Hyponatremia NOTE: This is the Professional Version. Hyponatremia is decrease in serum sodium concentration < 136 mEq/L caused by an excess of water relative to solute. Common causes include diuretic use, diarrhea, heart failure, liver disease, renal disease, and the syndrome of inappropriate ADH secretion (SIADH).

Medical Dictionary Hyponatremia (Low Sodium) Topic Guide. Hyponatremia (Low Sodium): Low levels of sodium in the blood is referred to as hyponatremia. Causes of hyponatremia include: pneumonia, lung cancer, brain tumors, kidney or heart failure, liver disease, and dehydration. Some of the symptoms of hyponatremia include: headache, nausea and vomiting, confusion, and lethargy. In acute hyponatremia seizures, coma, and even death may occur. Treatment of hyponatremia is generally to balance the electrolytes and raise the sodium levels in the blood.

Overview 1 Drinking too much water. 2  Because you lose sodium through sweat, drinking too much water during endurance activities, such as marathons and triathlons, can dilute the sodium content of your blood. 3  Drinking too much water at other times can also cause low sodium.

Electrolytes Increased sodium (hypernatremia) in the blood occurs whenever there is excess sodium in relation to water. There are numerous causes of hypernatremia; these may include kidney disease, too little water intake, and loss of water due to diarrhea and/or vomiting.

Hypernatremia (High Sodium) Certain conditions may cause an excess of sodium in the blood. Dehydration or a loss of body fluids from prolonged vomiting, diarrhea, sweating or high fevers. Dehydration from not drinking enough water. Drugs such as steroids, licorice, and certain blood pressure lowering medicines.

Electrolytes A decreased concentration of sodium (hyponatremia) occurs whenever there is a relative increase in the amount of body water relative to sodium. This happens with some diseases of the liver and kidney, in patients with congestive heart failure, in burn victims, and in numerous other conditions.

Common Lab Values And Test Result Meaning A low level of blood sodium is usually due to loss of too much sodium, too much water intake or retention, or to excess fluid accumulation in the body (edema). If the sodium level falls quickly, the person may feel weak and fatigued; in severe cases, he may experience confusion or even fall into a coma.

- Water is lost from the body in a variety of ways, including perspiration, imperceptible losses from breathing, and in the feces and urine. If the amount of water ingested consistently falls below the amount of water lost, the plasma sodium level will begin to rise, leading to hypernatremia.

- There are several common causes of sodium loss leading to low sodium levels, including diarrhea, excessive sweating, and vomiting. Medications that are prescribed to treat high blood pressure or fluid retention, called diuretics, can lead to low sodium levels.

Overview Causes. Sodium plays a key role in your body. It helps maintain normal blood pressure, supports the work of your nerves and muscles, and regulates your body's fluid balance. A normal sodium level is between 135 and 145 milliequivalents per liter (mEq/L) of sodium.Hyponatremia occurs when the sodium in your blood falls below 135 mEq/L. Many possible conditions and lifestyle factors can lead to hyponatremia, including: 1  Certain medications. Chronic, severe vomiting or diarrhea. 2  This causes your body to lose fluids and electrolytes, such as sodium. 3  Drinking too much water. 4  Because you lose sodium through sweat, drinking too much water during endurance activities, such as marathons and triathlons, can dilute the sodium content of your blood.
