Sodium is a key element for maintaining fluid balance inside and outside of cells, nerve and muscle function, and blood pressure stability. Patients with low sodium levels can generally take the following measures to replenish sodium:

1. Dietary supplementation: Suitable for patients with chronic or mild hyponatremia. Foods rich in sodium include salted duck eggs, ham, kelp, laver, peanuts, etc. At the same time, it is important to consume fresh fruits and vegetables, as well as legumes and nuts, which, although not high in sodium content, are nutritionally rich and help maintain overall health.

2. Oral supplementation: Oral administration of high-sodium fluids is suitable for patients with mild symptoms. Sodium chloride tablets or oral rehydration solutions can be taken orally; these medications mainly contain sodium chloride and can effectively replenish the body's sodium levels.

3. Intravenous infusion: Suitable for patients with severe symptoms or inadequate oral sodium replacement. Normal saline can be administered intravenously to rapidly replenish sodium levels.

The rate of sodium replacement must be carefully controlled, as rapid correction may cause brain cell damage and lead to more serious health complications. If in doubt, prompt medical attention is recommended.
