What a high Magnesium can mean
- Renal failure — magnesium accumulates without normal renal excretion.
- Magnesium-containing antacids and laxatives in patients with reduced renal function.
- Iatrogenic — eclampsia/pre-eclampsia treatment with magnesium sulfate.
When to discuss with a doctor
Symptoms of magnesium deficiency — muscle cramps, tremor, palpitations, refractory hypokalaemia — combined with a borderline-low serum level warrant a primary-care work-up. Patients on long-term PPI, diuretic or alcohol use benefit from periodic magnesium screening. Severe hypomagnesaemia with neurological symptoms is treated with IV replacement.
How to bring a high Magnesium down
A raised Magnesium is not brought down by diet or habits. It reflects something else going on, so what actually helps is finding that cause with a doctor - the value follows once the cause is addressed.
