What is the most common cause of hypernatremia?

(See ‘The importance of thirst’ below.) Although hypernatremia is most often due to water loss, it can also be caused by the intake of salt without water or the administration of hypertonic sodium solutions [2]. (See ‘Sodium overload’ below.) Hypernatremia due to water depletion is called dehydration.

What causes increased sodium levels?

Specific causes of hypernatremia include: Dehydration or a loss of body fluids from prolonged vomiting, diarrhea, sweating or high fevers. Dehydration from not drinking enough water. Drugs such as steroids, licorice, and certain blood pressure lowering medicines.

What are the risk factors of Hypernatremia?

Risk factors for hypernatremia include the following:

Advanced age.
Mental or physical impairment.
Uncontrolled diabetes (solute diuresis)
Underlying polyuria disorders.
Diuretic therapy.
Residency in nursing home, inadequate nursing care.
Hospitalization. [22, 32]

How does hyperlipidemia and Hyperproteinemia cause Pseudohyponatremia?

In states of hyperproteinemia or hyperlipidemia, there is an increased mass of the nonaqueous components of serum and a concomitant decrease in the proportion of serum composed of water. Thus, pseudohyponatremia results because the flame photometry method measures sodium concentration in whole plasma.

Why do lipids cause Pseudohyponatremia?

As summarized in Figure 2, pseudohyponatremia can be caused by elevated total protein, triglycerides, or very rarely by extremely elevated cholesterol. In cholestasis, Lp-X lipid particles carry most of the cholesterol in plasma and cause pseudohyponatremia.

What are the effects of high sodium levels?

But too much sodium in the diet can lead to high blood pressure, heart disease, and stroke. It can also cause calcium losses, some of which may be pulled from bone.
