[1] [7] Hypernatremia affects 0.3–1% of people in hospital. [2] It most often occurs in babies, those with impaired mental status, and the elderly. [2] Hypernatremia is associated with an increased risk of death, but it is unclear if it is the cause. [2]
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.
This is what causes the hypokalemia, hypertension, and hypernatremia associated with the syndrome. Patients often present with severe hypertension and end-organ changes associated with it like left ventricular hypertrophy, retinal, renal and neurological vascular changes along with growth retardation and failure to thrive.
In health care, diagnosis codes are used as a tool to group and identify diseases, disorders, symptoms, poisonings, adverse effects of drugs and chemicals, injuries and other reasons for patient encounters. Diagnostic coding is the translation of written descriptions of diseases, illnesses and injuries into codes from a particular classification.
The most common causes of high anion gap metabolic acidosis are: ketoacidosis, lactic acidosis, kidney failure, and toxic ingestions. [3]Ketoacidosis can occur as a complication of diabetes mellitus (diabetic ketoacidosis), but can occur due to other disorders, such as chronic alcoholism and malnutrition.
Hypernatremia is not common in individuals with no other health concerns. [3] Most individuals with this disorder have either experienced loss of water from diarrhea, altered sense of thirst, inability to consume water, inability of kidneys to make concentrated urine, or increased salt intake.
Diagnosis is typically based on urine testing and sometimes a kidney biopsy. [1] It differs from nephritic syndrome in that there are no red blood cells in the urine. [2] Treatment is directed at the underlying cause. Other efforts include managing high blood pressure, high blood cholesterol, and infection risk.
In patients with hypertension, diagnostic clues pointing to pseudohyperaldosteronism can be found on routine labwork. These include low serum potassium (hypokalemia), elevated serum sodium (hypernatremia), and elevated serum bicarbonate (metabolic alkalosis). [1] Urine studies may show elevated urine potassium .
