Overview 1 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. 2  Drinking too much water at other times can also cause low sodium. 3  Dehydration. 4  Taking in too little fluid can also be a problem.

Side Effects of Low Potassium & Low Sodium Causes of Decreased Potassium and Sodium. Low levels of sodium or potassium, referred to as hyponatremia and hypokalemia, respectively, may occur for a variety of reasons. Low potassium levels may occur because of a lack of potassium-rich foods, such as fruits and leafy green vegetables, in a person’s diet. Many individuals have a diet high in sodium due to convenience foods, so the lack of sodium-rich foods is not typically a concern.

- Low sodium levels can cause a number of symptoms. Generally, symptoms include disorientation, tiredness, and headache. Muscle cramps, and nausea are other common signs of low sodium levels. If the condition remains for a prolonged period of time, coma and seizures can occur.

- 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.

Hypernatremia (High Level of Sodium in the Blood) Blood tests are done to measure the sodium level. Usually, fluids are given intravenously to slowly reduce the sodium level in the blood. In hypernatremia, the body contains too little water for the amount of sodium (see Overview of Sodium). The sodium level in the blood becomes abnormally high when water loss exceeds sodium loss, as typically occurs in dehydration. Usually, hypernatremia results from dehydration (see Dehydration).

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.

Sodium A low level of blood sodium is called hyponatraemia, and is usually due to either too much sodium loss, too much water intake or retention, or fluid accumulation in the body (oedema). If sodium falls quickly, you may feel weak and tired; in severe cases, you may experience confusion or even fall into a coma.

Managing low sodium in the summer If your blood volume is normal and your sodium is low, medications may be the culprit (including anti-depressants, anti-seizure medications, or the recreational drug Ecstasy). There is also an important hormone called anti-diuretic hormone which causes the kidney to retain fluid.

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.

Hyponatremia (Low Sodium) 1 This class of drugs can cause excessive loss of sodium in the urine. 2  Hormonal diseases such as Addison's disease or adrenal insufficiency and hypothyroidism may be associated with low sodium levels. 3  Polydipsia, or excessive water intake, may cause water intoxication, diluting sodium levels.

- Low sodium is caused by excess fluid in the body, according to MedicineNet. It may also be due to loss of sodium and body fluid, and it may be caused by kidney failure. Symptoms of low sodium include headache, seizures, confusion or unstable mental state. Continue Reading.

- For lower than normal sodium levels (hyponatremia): 1  Low total body water and sodium levels may be due to dehydration, vomiting, diarrhea, over diuresis, or ketonuria.  Near-normal total body water may indicate SIADH, too much of the hormone vasopressin, hypothyroidism, or Addison's disease.

Hyponatremia (Low Sodium) Sodium levels must be corrected carefully. If your blood test results indicate you have a very low sodium level, your healthcare provider will cautiously correct the levels, to a safe level.. Intravenous (IV) fluids with a high-concentration of sodium, and/or diuretics to raise your blood sodium levels.

WebMD Â® Lupus Community The imbalance between sodium and water in your blood may occur. Hyponatremia occurs when the sodium in your blood falls below 135 mEq/L. Hyponatremia caused by excess water is commonly the result of kidney problems, heart failure or liver failure which dilutes the sodium concentration, causing 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. Hormonal changes. 2  Adrenal gland insufficiency (Addison's disease) affects your adrenal glands' ability to produce hormones that help maintain your body's balance of sodium, potassium and water. 3  Low levels of thyroid hormone also can cause a low blood-sodium level. 4  The recreational drug Ecstasy.

Top 30 Doctor insights on: What Causes Sodium Levels To Drop Okay to drink: It's unlikely under normal circumstances to drop your sodium levels. We see this in folks who are sweating a lot, vomiting, or having diarrhea because they lose sodium this way. We also see this in folks who have diabetes insipidous, in which case they will pee a lot.

Low sodium level Low sodium level. Low sodium level is a condition in which the amount of sodium (salt) in the blood is lower than normal. The medical name of this condition is hyponatremia. Sodium is found mostly in the body fluids outside the cells. It is very important for maintaining blood pressure.

Common Lab Values And Test Result Meaning Low blood sodium is rarely due to decreased sodium intake (deficient dietary intake or deficient sodium in IV fluids). A high blood sodium level (hypernatremia) is almost always caused by losing too much water (dehydration) without drinking enough water.

Managing low sodium in the summer Diuretics can lead to low sodium when the blood volume is low, but treat it when the volume is high. Too little fluids can cause low sodium if you are dehydrated, but treat a low sodium if you aren’t dehydrated. With the summer months coming up, low sodium and hyponatremia are sure to be more of a problem.

The Effects of Low Sodium in the Elderly Nausea and Malaise. Nausea may be a sign of a low sodium level. If you’ve been sick or have had reactions to medications that caused vomiting or diarrhea, you may have lost sodium as a result. Drinking too much water to compensate for your loss of fluids can contribute to low sodium levels.

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:

Normal Serum Sodium Levels For greater than normal sodium levels (hypernatremia): 1  If the amount of fluid in your body is low, you may have fluid loss due to excessive sweating, diarrhea, use of diuretics, or burns. 2  If your total body water is normal, high sodium levels may be due diabetes insipidus (too little of the hormone vasopressin).

Hypernatremia (High Sodium) Certain conditions may cause an excess of sodium in the blood. Specific causes of hypernatremia include: 1  Dehydration or a loss of body fluids from prolonged vomiting, diarrhea, sweating or high fevers. 2  Dehydration from not drinking enough water.ypernatremia is an electrolyte imbalance and is indicated by a high level of sodium in the blood. The normal adult value for sodium is 136-145 mEq/L.
