Hyponatremia treatment in Álvaro Obregón

Hyponatremia is a lower-than-normal level of sodium in the blood. Sodium helps regulate the body's water, so a drop in it can affect the function of several organs, especially the brain.

When to see a doctor? Care is advisable with headache, nausea, confusion, weakness or, in severe cases, marked drowsiness or seizures.

Common causes: It may be related to excess fluids, losses from vomiting or diarrhea, certain medications, or heart, kidney or hormonal conditions.

Which specialist treats it? The internist and the nephrologist study the balance of fluids and salts, the pediatric nephrologist cares for children, and an acute case may require emergency care. If a test shows low sodium or these symptoms appear, it's sensible for a professional to assess the cause.
