Low sodium levels, or hyponatremia, is a condition in which the levels of sodium, or salt, in your blood stream are too low. Uncorrected low blood sodium can cause fatigue, headache, confusion, hallucinations, muscle weakness, nausea and coma. After the cause of hyponatremia is assessed and treated, you can raise the sodium levels in the blood.
Reduce your intake of water to raise your sodium levels in your blood. Water that you drink is absorbed in your blood and reduces the overall concentration of sodium and other electrolytes in your bloodstream. Therefore, drinking less water will prevent dilution and raise the concentration of sodium in your blood stream.
Drink a sports drink that contains sodium. Sports beverages contain sodium in addition to other electrolytes and may be necessary if your sodium levels are low. Particularly, a sports drink could be beneficial when you lose a lot of sweat running or performing other exercises.
Add additional salt to the foods you eat to increase the sodium levels in your blood stream. Additional sodium that you add to your foods will be absorbed in your digestive tract and absorbed by your blood stream. Eat low calorie foods to prevent weight gain. Sprinkle salt on salads, sandwiches, vegetables or fruit to increase sodium intake.
