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.
These electrolytes must be replaced to keep the electrolyte concentrations of the body fluids constant. 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]
Diagnosis is based on clinical and laboratory findings of low serum osmolality and low serum sodium. [13] Urinalysis reveals a highly concentrated urine with a high fractional excretion of sodium (high sodium urine content compared to the serum sodium). [14] A suspected diagnosis is based on a serum sodium under 138.
Hypoosmolar hyponatremia is a condition where hyponatremia is associated with a low plasma osmolality. [1] The term "hypotonic hyponatremia" is also sometimes used.[2]When the plasma osmolarity is low, the extracellular fluid volume status may be in one of three states: low volume, normal volume, or high volume.
As a diagnosis of exclusion, a diagnosis of primary polydipsia may be the result of elimination of the possibility of diseases causing similar signs and symptoms, such as diabetes insipidus. [ 12 ] Diagnosis may be complicated by the fact that chronic and extreme compulsive drinking may impair the response of the kidneys to vasopressin , thus ...
Tea and toast syndrome is a form of malnutrition commonly experienced by elderly people who cannot prepare meals and tend to themselves. The term is not intrinsic to tea or bread products only; rather, it describes limited dietary patterns that lead to reduced calories resulting in a deficiency of vitamins and other nutrients.
Other authors associated hyponatremia in subarachnoid hemorrhage with increased levels of natriuretic peptides, negative sodium balance, and low central venous pressure. [30] [31] [32] A valid diagnosis of "salt wasting" requires evidence of inappropriate urinary salt losses and a reduced "effective arterial blood volume".
Exercise-associated hyponatremia (EAH) is a fluid-electrolyte disorder caused by a decrease in sodium levels (hyponatremia) during or up to 24 hours after prolonged physical activity. [1] This disorder can develop when marathon runners or endurance event athletes drink more fluid, usually water or sports drinks, than their kidneys can excrete ...
