Magnesium contributes to nerve, muscle and heart function. A low blood level may produce no symptoms or may accompany other electrolyte disturbances.

What does this result or symptom mean?

Poor intake, persistent diarrhea, certain kidney problems, diuretics and some acid-suppressing medicines may affect levels. Potassium and calcium can be low at the same time, and serum magnesium does not perfectly reflect total body stores.

Practical steps and preparation

Record diarrhea, diet and medications. People with kidney disease should not use magnesium supplements without medical advice.

When should you seek prompt care?

Seizures, significant palpitations, fainting or severe muscle spasms need urgent care.

Frequently asked question

Does every muscle cramp mean magnesium deficiency?

No. Cramps have many possible explanations.

Checklist before a clinical consultation

To make your appointment more useful, consider the following:

  • Write down when the problem began and how it has changed.
  • Bring a list of medicines, supplements and relevant previous test results.
  • Prepare the questions you want to discuss.
