Hypervolemic Hyponatremia

Hypervolemic hyponatremia is a disorder in which the blood sodium is low while there is at the same time an excess of fluid in the body, which dilutes this essential mineral. Sodium helps maintain fluid balance and the function of nerves and muscles.

Possible manifestations: Swelling, fatigue, confusion, nausea or weakness; in more marked cases it may affect alertness.

When to see a doctor? It's important to seek care with swelling accompanied by confusion, drowsiness or significant weakness, situations that may require prompt evaluation.

Which specialist treats it? The internist evaluates this type of imbalance, with support from the endocrinologist and the general surgeon depending on the context. When these signs appear, seeking a professional evaluation is the most advisable course.
