Or that you should urinate on a jellyfish sting? Or that in case of a seizure you should put a spoon into the victim’s mouth? These common first-aid myths, though well-intentioned, can be more harmful than helpful. And they come up each time I teach a first-aid course!</p> Fri, 12 May 2023 10:00:00 +0000 Cat Wang, B.Sc. 9507 at /oss /oss/article/health/magnesium <p> </p> <p><u>Causes</u></p> <p>There are basically two ways to develop low magnesium levels. Like potassium, magnesium is excreted in the urine, so diuretics, which often cause hypokalemia (low potassium), also generally cause hypomagnesemia (low magnesium). In fact hypokalemia and hypomagnesemia often go together. Patients who abuse alcohol are often hypomagnesemic as well because alcohol can cause a temporary dysfunction in the renal tubules causing magnesium to be excreted in the urine.</p> Thu, 11 Apr 2019 15:26:48 +0000 Christopher Labos MD, MSc 7716 at /oss
