When kidneys detect an overabundance of salt in your bloodstream, they work overtime and diligently to filter the same. This excessive salt is eliminated via the urine.
Whenever you consume a large amount of salt with insufficient water to adequately filter it out of your system, you ultimately end up losing more water than you ingested. Consequentially, leaving a hazardous quantity of salt in your system.
Dehydration will ultimately set in as your kidneys continue to form excess urine to dilute the salt intake.

Kidneys are trained to maintain a precise sodium-to-water ratio in your body. When you have more salt in your system than required, the kidneys will retain extra water to compensate for the excessive salt in the body.
Swelling, particularly in the hands and feet, can also be seen due to increased water retention. You may weigh more than usual as well if bloated!
