How can increased sodium consumption cause pulmonary edema?

Fluid retention. The body has several mechanisms to keep the concentration of salt in the body relatively constant. Excess salt intake may cause the body to activate mechanisms leading to fluid retention in response. The added fluid burden increases the work load on the heart, and if the pumping function is impaired can lead to fluid accumulation in the lungs.

The same goes if you take too much salt and have abnormal heart or kidney function. Read more...
