Sodium is an essential mineral that helps the body maintain fluid balance and supports normal nerve and muscle function. A low level of sodium in the blood is called hyponatremia. It can occur for several reasons, including certain medications, kidney, heart or liver problems, hormonal disorders, vomiting, diarrhoea and excessive fluid intake. The severity of symptoms depends on how low the sodium level falls and how quickly it changes.
Common symptoms include nausea, headache, tiredness, weakness, dizziness, muscle aches, reduced concentration, confusion and excessive drowsiness. Severe hyponatremia can affect the brain and may cause worsening confusion, coordination problems, muscle twitching, seizures or loss of consciousness. In serious cases, brain swelling can become life-threatening. People experiencing severe symptoms should seek emergency medical attention. A blood test is generally needed to confirm low sodium levels, and treatment depends on the underlying cause and severity. Sodium levels should not be corrected suddenly without medical supervision.
Note: Low sodium can have several underlying causes, and the symptoms can overlap with other health conditions. Do not increase salt intake or take medicines on your own. Seek medical advice for proper testing and treatment.
