Excessive sodium intake: The best way to discharge sodium when sodium intake is excessive is to drink a lot of water, so that the sodium in the body is discharged with sweat and urine. 2. Obstructed sodium excretion: When sodium excretion is obstructed, diuretics and other medications (such as furosemide, etc.) should be applied to make sodium excretion, and attention should be paid to drinking water so as not to cause dehydration. 3.
