Hyponatremia

Hyponatremia occurs when the sodium level in your blood drops too low. Sodium is an essential electrolyte that helps regulate water balance in your body and supports nerve and muscle function. When sodium is decreased, water can move into cells, causing them to swell. This can lead to symptoms like headache, confusion, nausea, and in severe cases, seizures or coma. Common causes include drinking too much water, certain medications, or health conditions like heart or kidney problems. Prompt diagnosis and treatment are important to restore normal sodium levels and prevent complications.
