High Blood Pressure
Potassium also plays a role in blood pressure. That is why low potassium levels are often associated with heightened blood pressure. Without enough potassium, the blood vessels cannot relax, and this may cause constrictions that elevate pressure. Add increased sodium intake, and you might have a problem.
In fact, people who take in too much sodium will feel the effects much more if they are not balancing their salt consumption with potassium. The body becomes extremely sensitive to sodium when hypokalemic. Additional symptoms associated with high blood pressure include feeling faint, lightheaded, and losing consciousness (passing out). You might also feel dizzy when sitting down or standing up too fast.
