Magnesium overdose signs and symptoms

Magnesium is a naturally occurring mineral in foods as well as in the human body. It is great for healthy bone formation, blood sugar control and electrical conduction in the heart and nerve function. It is also beneficial in maintaining good heart health and gives you great energy. But, as with all good things, too much of it can be bad!

The medical term for this is hypomagnesemia.

Magnesium overdose, which is usually the result of taking too much of a magnesium supplement or a medication containing magnesium, can lead to many negative reactions, including kidney failure, heart failure and in some cases, death.

Signs and symptoms

The symptoms of a magnesium overdose can be confused with many other conditions, but generally, patients experience nausea, vomiting, diarrhoea, constipation and gastric discomfort and swelling.

Some people have reported feeling very lethargic and experience inexplicable joint pain.

Other signs include low blood pressure, muscle weakness and urine retention.

If you experience adverse symptoms, such as diarrhoea, when you take magnesium supplements or medications containing magnesium, you may be taking too much magnesium in these forms. If this is the case, you may need to speak to your doctor for guidance, Healthline advises.

Severe overdoses of magnesium are rare, though. Visit your doctor immediately to receive a proper diagnosis.

High in Magnesium

When it comes to medication, laxatives have a high magnesium content. Medications used to aid indigestion also have high quantities of magnesium. A tablespoon of Milk of Magnesia contains 500 mg of elemental magnesium. A daily dose for adults is up to 4 tablespoons a day.

Foods high in magnesium are nuts, green leafy vegetables, legumes and seafood.

According to the National Institutes of Health’s Office of Dietary Supplements, healthy adult men should generally consume 400 to 420 milligrams (mg) of magnesium daily. Healthy adult women should consume 310 to 320 mg daily. Pregnant women are advised to consume a higher dose than women who aren’t pregnant.
