Hypernatremia is the American English spelling of hypernatraemia, which has the same meaning in British English. It is a health condition where a person has too much sodium in the blood.
Hemolysis itself does not directly cause hypernatremia, which is an elevated sodium concentration in the blood. However, hemolysis can lead to the release of intracellular potassium and other substances into the bloodstream, potentially affecting electrolyte balance. If hemolysis occurs alongside dehydration or other conditions that lead to reduced fluid volume, hypernatremia may develop as a secondary effect. Therefore, while hemolysis is not a primary cause of hypernatremia, it can be associated with conditions that contribute to it.
