Understanding the Main Factors Behind Hyponatremia
Learn about the primary causes of hyponatremia, including medication effects, health conditions, excessive water intake, and hormonal imbalances. Understanding these factors helps in early diagnosis and management of this electrolyte disturbance.

Hyponatremia occurs when blood sodium levels drop below 135 mEq/L, with normal levels ranging from 135 to 145 mEq/L. Sodium plays a vital role in regulating blood pressure, supporting nerve and muscle functions, and maintaining overall fluid balance. Several factors can lead to hyponatremia. Here are the key causes:
Medications and Pharmaceuticals
Certain drugs, including diuretics, antidepressants, and painkillers, can increase fluid loss or alter sodium levels, leading to hyponatremia.
Cardiovascular, Liver, and Kidney Conditions
Issues like heart failure, liver diseases, or kidney problems can cause fluid buildup in the body, diluting sodium levels and triggering hyponatremia.
Syndrome of Inappropriate Antidiuretic Hormone (SIADH)
This condition involves excessive production of ADH, leading to water retention and lowered sodium concentration in blood.
Excessive Water Intake
Engaging in intense activities that cause sweating and consuming large quantities of water can wash out sodium, resulting in low levels. Overhydration alone can also decrease sodium in the body.
Recreational Drug Ecstasy
Using ecstasy can cause rapid fluid loss and excessive sweating, dramatically reducing sodium levels. The drug’s amphetamine component raises the risk of severe hyponatremia.
Hormonal Imbalances
Conditions like Addison’s disease impair adrenal hormone production, affecting sodium, potassium, and water balance. Low thyroid hormone levels can also contribute to hyponatremia.
