What causes sodium levels to drop?

A low sodium level has many causes, including consumption of too many fluids, kidney failure, heart failure, cirrhosis, and use of diuretics. Symptoms result from brain dysfunction.

What are some neurological symptoms of hyponatremia?

Mild hyponatremia (serum sodium 130-135 mmol/L) is usually asymptomatic but severe acute-onset hyponatremia (serum sodium <125 mmoll) causes brain cells to swell due influx of water (cerebral edema) with consequent neurological symptoms such as headache, agitation, confusion impaired mental function.

Although sodium may take longer to normalise within the brain and hence the neuropsychiatric symptoms take longer to resolve but serum levels should be corrected as advised earlier no faster than 10-12 mEq/L in 24 hrs. Levels lower than 105 mEq/L are prone to develop osmotic demyelination if corrected too rapidly.

Can low sodium make you crazy?

Will eating more salt help hyponatremia?

In elderly patients with a diet poor in protein and sodium, hyponatremia may be worsened by their low solute intake. The kidney’s need to excrete solutes aids in water excretion. An increase in dietary protein and salt can help improve water excretion.
