How Long Does Salt Stay in Your Body?

Key Takeaways

The salt you consume generally stays in your system for a day or more before being eliminated through urination.

Elimination can take longer for people who eat a lot of salt, have kidney disease or a potassium deficiency, or are dehydrated.

Drinking more water, increasing physical activity, eating potassium-rich foods, and cutting back on salt may improve excretion and potentially improve blood pressure.

Generally, salt (sodium chloride) stays in your body anywhere from 24 hours to three days as it is gradually excreted in urine. Different factors can influence how fast or slowly elimination occurs, including the amount of salt you consume, the amount of water you drink, your level of physical activity, and any underlying medical conditions you may have.
