Sodium management strategies -

Studies show that when people follow a lower-sodium diet, they start to prefer it, and that the foods they once enjoyed taste too salty. Try it and see for yourself!

There are several salt substitutes on the market that replace some or all of the sodium with potassium. Potassium salt tastes similar to sodium chloride, except when heated it can have a bitter aftertaste.

Talk with your health care professional about whether a salt substitute is right for you. Written by American Heart Association editorial staff and reviewed by science and medicine advisors. See our editorial policies and staff.

Home Healthy Living Healthy Eating Eat Smart Sodium How to Reduce Sodium in Your Diet. Most people should cut back on sodium to improve their health. When shopping for food: Choose packaged and prepared foods carefully. Compare labels and choose the product with the lowest amount of sodium per serving you can find.

Different brands of the same food can have lower or higher sodium levels. Compare this with the same serving of prepared rotisserie chicken pre-seasoned with sodium, which can have mg of sodium a serving!

Select condiments with care. For example, soy sauce, bottled salad dressings, dips, ketchup, jarred salsas, capers, mustard, pickles, olives and relish can be loaded with sodium. Look for reduced-sodium or lower-sodium versions.

The Heart-Check mark designates foods that can be part of an overall healthy dietary pattern. When preparing food: Use flavorful ingredients.

In these patients, the main causes of hyponatremia are renal disorders, endocrine deficiencies, reset osmostat syndrome, syndrome of inappropriate antidiuretic hormone secretion SIADH , and drugs or medications. Because of their prevalence and importance, SIADH and drugs deserve special mention, and the author will elaborate on these causes later in the article.

Renal disorders that cause hyponatremia include sodium-losing nephropathy from chronic renal disease e. Endocrine disorders are uncommon causes of hyponatremia. Diagnosing hypothyroidism or mineralocorticoid deficiency i. In either case, the serum levels of thyroid-stimulating hormone TSH , cortisol, and adrenocorticotropic hormone ACTH should be measured, because hypothyroidism and hypoadrenalism can coexist as a polyendocrine deficiency disorder i.

The reset osmostat syndrome occurs when the threshold for antidiuretic hormone secretion is reset downward. Patients with this condition have normal water-load excretion and intact urine-diluting ability after an oral water-loading test.

The condition is chronic—but stable—hyponatremia. Patients with extra-renal sodium loss have a low urinary sodium concentration less than 30 mmol per L as the body attempts to conserve sodium.

Causes include severe burns and gastrointestinal losses from vomiting or diarrhea. Diuretic therapy, on the other hand, can cause either a low or a high urinary-sodium concentration, depending on the timing of the last diuretic dose administered, but the presence of concomitant hypokalemia is an important clue to the use of a diuretic.

Medications and drugs that cause hyponatremia are listed in Table 1. Diuretics cause a hypovolemic hyponatremia. Fortunately, in most cases, stopping the offending agent is sufficient to cause spontaneous resolution of the electrolyte imbalance.

Antidiuretic hormone causes water retention, so hyponatremia then occurs as a result of inappropriately increased water retention in the presence of sodium loss. The diagnostic criteria for SIADH are listed in Table 2. SIADH is a diagnosis of exclusion and should be suspected when hyponatremia is accompanied by urine that is hyperosmolar compared with the plasma.

This situation implies the presence of a low plasma osmolality with an inappropriately high urine osmolality, although the urine osmolality does not necessarily have to exceed the normal range.

Another suggestive feature is the presence of hypouricemia caused by increased fractional excretion of urate. Any cerebral insult, from tumors to infections, can cause SIADH. Less common causes include acute intermittent porphyria, multiple sclerosis, and Guillain-Barré syndrome.

The treatment of hyponatremia can be divided into two steps. First, the physician must decide whether immediate treatment is required. This decision is based on the presence of symptoms, the degree of hyponatremia, whether the condition is acute arbitrarily defined as a duration of less than 48 hours or chronic, and the presence of any degree of hypotension.

The second step is to determine the most appropriate method of correcting the hyponatremia. Shock resulting from volume depletion should be treated with intravenous isotonic saline. Acute severe hyponatremia i. In patients with chronic hyponatremia, overzealous and rapid correction should be avoided because it can lead to central pontine myelinolysis.

In patients who have difficulty adhering to fluid restriction or who have persistent severe hyponatremia despite the above measures, demeclocycline Declomycin in a dosage of to 1, mg daily can be used to induce a negative free-water balance by causing nephrogenic diabetes insipidus.

Loop diuretics can be used in severe cases. Newer agents such as the arginine vasopressin receptor antagonists have shown promising results 39 and may be useful in patients with chronic hyponatremia. In all patients with hyponatremia, the cause should be identified and treated.

Some causes, such as congestive heart failure or use of diuretics, are obvious. Other causes, such as SIADH and endocrine deficiencies, usually require further evaluation before identification and appropriate treatment. DeVita MV, Gardenswartz MH, Konecky A, Zabetakis PM.

Acute or symptomatic hyponatremia can lead to significant rates of morbidity strqtegies mortality. Sodium management strategies manaement, a major determinant of total body water homeostasis, is measured by the number of solute particles present in 1 kg of plasma. It is calculated in mmol per L by using this formula:. Total body sodium is primarily extracellular, and any increase results in increased tonicity, which stimulates the thirst center and arginine vasopressin secretion. Arginine vasopressin then acts on the V2 receptors in the renal tubules, causing increased water reabsorption. The opposite occurs with decreased extracellular sodium: a decrease inhibits the thirst center and arginine vasopressin secretion, resulting in diuresis.

Sodum presence suggests a worse prognosis in patients with liver cirrhosis, pulmonary hypertension, managemet infarction, chronic kidney disease, hip fractures, and pulmonary embolism. The most common classification system for hyponatremia is based on volume status: hypovolemic decreased total body water with greater decrease in sodium leveleuvolemic increased total body water with normal sodium leveland hypervolemic increased total body water compared with sodium. Plasma osmolality has a role in the pathophysiology of hyponatremia. Osmolality refers to the total concentration of solutes in water. Effective osmolality is the osmotic gradient created by solutes that do not cross the cell membrane.
