Hyponatremia or hyponatraemia is a low concentration of sodium in the blood. [4] It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L), with severe hyponatremia being below 120 mEq/L. [3] [8] Symptoms can be absent, mild or severe.
Doing so lessens the chance of increaseing the serum sodium level too rapidly as blood volume rises and ADH levels fall. [citation needed] In people who are volume depleted (e.g., their blood volume is too low), ADH secretion is increased since volume depletion is a potent stimulus for ADH secretion.
“Zero dietary sodium intake may lead to clinically significant low blood sodium levels, which can cause severe muscle cramps, weakness, nausea and vomiting, seizures and coma, shock or even ...
Low sodium intake level was a mean of <115 mmol (2645 mg), usual sodium intake was 115-215 mmol (2645–4945 mg), and a high sodium intake was >215 mmol (4945 mg), concluding: "Both low sodium intakes and high sodium intakes are associated with increased mortality, consistent with a U-shaped association between sodium intake and health outcomes".
Hyponatremia, or low sodium, is the most commonly seen type of electrolyte imbalance. [12] [13] Treatment of electrolyte imbalance depends on the specific electrolyte involved and whether the levels are too high or too low. [3] The level of aggressiveness of treatment and choice of treatment may change depending on the severity of the ...
All three patients were unable to prevent urinary sodium loss despite low serum sodium levels and no evidence of extrarenal sodium loss. Their hyponatremia responded to salt therapy. They postulated that this provided evidence of an extra-pituitary cerebral structure mediating normal sodium metabolism but were unsure of its location or ...
Hypoaldosteronism causes low sodium (hyponatremia), high potassium (hyperkalemia), and metabolic acidosis, a condition in which the body produces excess acid.These conditions are responsible for the symptoms of hypoaldosteronism, which include muscle weakness, nausea, palpitations, irregular heartbeat, and abnormal blood pressure.
One of the most common side effects of spironolactone is frequent urination. Other general side effects include dehydration, hyponatremia (low sodium levels), mild hypotension (low blood pressure), [86] ataxia (muscle incoordination), drowsiness, dizziness, [86] dry skin, and rashes.
