The physician has put him on a fluid restriction, a potassium restriction, and a phosphorus restriction.

Chronic kidney disease can cause a decrease in kidney function, leading to a decrease in the production of active Vitamin D. This in turn causes a decrease in calcium absorption in the gut, resulting in low calcium levels in the blood. In response, the body releases hormones that stimulate bone resorption (breakdown of bones) to release more calcium into the bloodstream. During this process, there is a release of phosphorus from the bones, leading to high levels of phosphorus in the blood. Therefore, the low calcium levels in Mr. M's initial chemistry panel could be a contributing factor to his high phosphorus levels.
