What is Hyponatremia?
Hyponatremia occurs when the sodium level in your blood is lower than normal. Sodium is crucial for nerve and muscle function, as well as maintaining fluid balance. This condition arises when water intake exceeds the body's ability to excrete it, diluting the sodium content in the blood. Symptoms range from mild, such as nausea and headache, to severe, such as confusion and seizures.
Causes of Hyponatremia
This condition can result from various factors, including excessive water consumption, certain medications, and underlying health issues like heart failure or kidney disease. In some cases, the syndrome of inappropriate antidiuretic hormone secretion (SIADH) causes the body to retain water, worsening hyponatremia. It's crucial to identify the root cause to tailor the appropriate treatment.

Treatment and Management
Managing hyponatremia involves addressing the underlying cause and regulating water intake. In mild cases, simply reducing water consumption might suffice. In more severe situations, medical intervention is necessary, which may include intravenous sodium solutions or medications to block excess hormone activity. Monitoring and regular check-ups are vital to prevent recurrence.
