What is hyponatremia?

Hyponatremia refers specifically to a condition where there is a low concentration of sodium in the blood. Sodium is a crucial electrolyte that helps regulate fluid balance, blood pressure, and overall cellular function in the body. When sodium levels drop below the normal range, it can lead to a variety of symptoms and complications, including nausea, headache, confusion, and in severe cases, seizures or coma.

Understanding hyponatremia is important, especially in the context of patients undergoing hemodialysis. Fluid shifts and imbalances in electrolytes can occur during the dialysis process, making it essential for healthcare providers to monitor sodium levels and manage them appropriately to prevent adverse effects.

Recognizing the significance of sodium's role in maintaining homeostasis can help in making informed decisions about treatment options and adjustments required for patient care.
