hyponatremia

Hyponatremia is a medical condition characterized by an abnormally low level of sodium in the blood. This deficiency can disrupt the balance of ions and water in body fluids and tissues. Symptoms may include nausea, vomiting, headache, confusion, fatigue, and muscle cramps. In severe cases, hyponatremia can lead to seizures, coma, and can be life-threatening if untreated.12

Factors that can increase the risk of hyponatremia include the use of certain pain relievers like aspirin and ibuprofen, as well as excessive hydration, particularly during prolonged physical activity such as marathons. Sodium is crucial for maintaining tissue-water and acid-base balance, and its deficiency can impair normal activity patterns.12
