What condition is indicated by hypernatremia?

Hypernatremia refers to an elevated level of sodium in the blood. This condition occurs when there is an imbalance in the body's sodium and water levels, often due to insufficient water intake or excessive water loss. High sodium levels can lead to various complications, including dehydration of cells, increased blood pressure, and strain on the cardiovascular system. Recognizing hypernatremia is crucial for managing electrolyte balance, particularly in patients undergoing hemodialysis, as it can influence fluid and sodium management strategies in their treatment plans.
