Blood Magnesium Test

A magnesium level this high is usually due to kidney disease or to getting a lot of magnesium in medications or from supplements.

 

Some antacids and laxatives contain magnesium. If you take any magnesium containing products, stop them now. If you are not taking antacids or laxative, but are taking some other kind of vitamin, herbal, or dietary supplement, check to see if it contains magnesium.

 

Call your doctor for advice.
