Hyponatremia in elderly subjects is mainly caused by drugs (more frequently thiazides and antidepressants), the syndrome of inappropriate antidiuretic hormone secretion (SIAD) or endocrinopathies; however, hyponatremia is multifactorial in a significant proportion of patients.
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.
Treatment for low blood sodium cutting back on fluid intake. adjusting the dosage of diuretics. taking medications for symptoms such as headaches, nausea, and seizures. treating underlying conditions. infusing an intravenous (IV) sodium solution.
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.
Hyponatremia treatments may include changing a medication that affects your sodium level, treating the underlying disease, changing the amount of water you drink or changing the amount of salt in your diet.
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.
Hyponatremia occurs when sodium levels in the blood are too low . Symptoms include lethargy, confusion, and fatigue. It can result from underlying conditions, such as kidney failure, or other factors, such as drinking too much water or taking certain medications.
Who is most at risk for hyponatremia? Anyone can develop hyponatremia. Hyponatremia is more likely in people living with certain diseases, like kidney failure, congestive heart failure , and diseases affecting the lungs, liver or brain . It often occurs with pain after surgery.
Treatment Intravenous fluids. Your doctor may recommend IV sodium solution to slowly raise the sodium levels in your blood. Medications. You may take medications to manage the signs and symptoms of hyponatremia, such as headaches, nausea and seizures.
How is the sodium blood test done? This test is performed on a blood sample, obtained by venipuncture. A technician will insert a small needle into a vein on your arm or hand. This will be used to fill a test tube with blood.
Chronic caffeine intake increases urinary sodium excretion without affecting plasma sodium concentration .
Patients with hyponatremia had a hospital stay of 7.6 days compared with 5.6 days for those with normonatremia, a significant difference between the groups. Hyponatremia at the time of hospital admission is associated with an increased risk of death and longer in-patient stays, according to a new study.
But hyponatremia among inpatients is usually subacute or chronic and should be corrected gradually to avoid causing osmotic demyelination syndrome, experts emphasized.
The authors of the study report that hyponatremia symptoms can develop if a person drinks 3–4 liters of water in a short period, though they do not give a specific time estimate. According to one case report, soldiers developed symptoms after consuming at least 2 quarts (1.9 liters) of water per hour. 6 дней назад
