One is by increase production by eroding the bones and the other is by dedcresed excretion in the kidneys. Now, action/reaction ...you keep Ca but you lose K. Hence, (wow what a big word!) you get hypokalemia. I try to remember they are inversely proportional (Ca and K) Also, like in the this case...Mg and K are always hand-in-hand. So if Mg goes down, so does K. In the very rare cases where Mg is th primary cause...K will be affected too. OR IS IT PHOSPHATE?! HOW THE HECK WILL MY PTS SURVIVE ME?!!!!!
WE have a problem here! I regret to inform that this post may be incorrect and I need your hellp to prove my hypothesis null. Iseem to have maded a mistake and I thank drsap for inquireing on hypokalemia in hyperparathyroidism. This patient had hypokalemia and that was the clue for suspecting hypomagnesemia as the cause for his pseudogout. It's complicated, I hope I don't get lost or lose you. Although hyperparathyroidism is the most common cause of pseudogout, it WILL NOT produce hypokalemia (unless I'm wrong here and please someone correct me!). So the answer to this Q was originally hypomagnesemia; because he is under 50, and you should think of the 4 Hs (mentioned above). I'm sorry for the inconvenience. I hope all this trrouble only helps to create more memory!
