Management of Hyponatremia This increase in total body water isgreater than the total body sodium level,resulting in edema. The three main causes ofhypervolemic hyponatremia are congestiveheart failure, liver cirrhosis, and renal dis-eases such as renal failure and nephrotic syn-drome.

Management of Hyponatremia High urinary sodium concentration in thepresence of low plasma osmolality can be caused by renal disorders, endocrine deficiencies,reset osmostat syndrome, SIADH, and medications. Low urinary sodium concentration iscaused by severe burns, gastrointestinal losses, and acute water overload.

Hyponatremia and Hypernatremia Summary. 1  Hyponatremia and hypernatremia result mainly from disorders of water metabolism. 2  Water metabolism is tightly regulated by hypothalamic osmoreceptors, ADH release, and an adequate renal response to ADH. 3  Most disorders of water metabolism are caused by dysfunctional release or renal response to ADH.

Overview 1 Medical conditions that may increase your risk of hyponatremia include kidney disease, syndrome of inappropriate anti-diuretic hormone (SIADH) and heart failure, among others.

Review of carbamazepine-induced hyponatremia Numerous drugs can cause hyponatremia by increasing the release of ADH from the posterior pituitary, by enhancing ADH action on the kidney or by acting directly on the kidney [3]. The syndrome of inappropriate ADH secretion (SIADH) results from persistent ADH release.

Hyponatremia Definition and Etiology Hyponatremia is defined as a serum sodium concentration lower than 136 mmol/L. 2 It can result from a particular laboratory technique or from improper blood collection, excessively high water intake, or, most commonly, an inability of the kidneys to excrete free water (see later, “Pathophysiology and Natural History”). 3

Overview Many possible conditions and lifestyle factors can lead to hyponatremia, including: 1  Certain medications. Some medications, such as some water pills (diuretics), antidepressants and pain medications, can cause you to urinate or perspire more than normal. 2  Heart, kidney and liver problems.

Hyponatremia 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).

Electrolytes 1 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. 2  A decreased concentration of sodium (hyponatremia) occurs whenever there is a relative increase in the amount of body water relative to sodium.

Overview 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: Certain medications. Some medications, such as some water pills (diuretics), antidepressants and pain medications, can cause you to urinate or perspire more than normal.

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

Hyponatremia Low volume hyponatremia can occur from diarrhea, vomiting, diuretics, and sweating. Normal volume hyponatremia is divided into cases with dilute urine and concentrated urine. Cases in which the urine is dilute include adrenal insufficiency, hypothyroidism, and drinking too much water or too much beer.

What Causes Low Sodium in the Body? Quick Answer. Low sodium in the body, also known as hyponatremia, is caused by hormonal changes; dehydration; heart, kidney and liver problems; or chronic, severe diarrhea or vomiting, according to Mayo Clinic. Some medications, such as antidepressants, pain relievers and water pills may also cause low sodium levels. Keep Learning.
