Hypermagnesaemia Or High Magnesium Levels

Hypermagnesaemia is a rare disease which in most cases is related to kidney problems, but can also have other causes.

Hypermagnesaemia or high levels of magnesium

As hypermagnesemia refers to a too high concentration of magnesium in the blood. The normal value of this element in an adult is 1.5-2.5 mg / dl. If this value is exceeded in laboratory tests, one speaks of hypermagnesaemia .

The appearance of hypermagnesaemia suggests an electrolyte disorder in the body. Magnesium is one of the organism’s electrolytes. This means that it carries an electrical charge when it is dissolved in the body fluids. However, most of the magnesium in the body has no electrical charge.

In any case , hypermagnesaemia is a rare disease and in most cases it is related to kidney problems. Usually it only occurs in people who have kidney failure.

The magnesium in the body


Magnesium is a fundamental element for all living things. It is a mineral nutrient that is essential to life. Magnesium is present in the cells and plays a crucial role in their balance and proper functioning.

There are more than 300 enzymes that require magnesium to perform some of its most important functions. In principle , the cells themselves regulate the flow of magnesium. From there, this element activates and controls various biochemical reactions in the body.

Maintaining normal magnesium levels is vital to good health. A deficiency or excess of this element can lead to heart problems and nervous system disorders. Therefore, hypermagnesaemia is a delicate condition that can have very serious consequences.

Causes of Hypermagnesaemia

The kidneys are the organs that are responsible for excreting magnesium. Therefore, any abnormal condition or damage to these organs can lead to hypermagnesaemia. The main reasons for this are as follows:

  • Kidney failure: this is the most common cause of hypermagnesaemia. Kidney failure prevents the normal excretion of magnesium.
  • Excessive magnesium intake: Diet or excessive use of some substances, such as laxatives, antacids, or some dietary supplements, can cause this problem.
  • Chemotherapy: Some chemotherapy treatments lead to the development of tumor lysis syndrome. This in turn causes the magnesium level to rise.
  • Extensive burns.
  • Other chronic diseases: for example, hypothyroidism and Addison’s disease

    Symptoms and Diagnosis

    Hypermagnesaemia is rare

    The diagnosis of hypermagnesaemia is made by a blood test. Normally , if the magnesium level is only slightly elevated, there are no noticeable symptoms. If your magnesium levels continue to rise, you are likely to experience the following symptoms:

    • Muscle weakness
    • Vomiting and nausea
    • a headache
    • Irregular or slow heartbeat
    • Warmth and redness on the face
    • Drowsiness
    • Dizziness, fainting, and slow reflexes
    • Slow breathing
    • Muscle paralysis

    If a person has hypermagnesaemia and falls asleep without being able to wake them up, or if they have great difficulty moving their arms and legs, they must be taken to the hospital immediately.

    It is also advisable to consult a doctor as soon as possible in the event of slow breathing and heart rate, as well as drowsiness and muscle weakness.

    Treatment of hypermagnesaemia

    Treatment for increased levels of magnesium in the blood depends entirely on the cause. Those with kidney failure, who are the hardest hit group, must follow strict medical controls while taking their medication and their general health.

    Dialysis is often used in these cases.

    Kidney dialysis is a treatment that helps the kidneys remove some chemicals and wastes from the blood when the kidneys can no longer perform this function on their own.

    Sometimes dialysis is not necessary; treatment with medication is sufficient to improve the situation.

    Usually calcium gluconate or diuretics are prescribed. The drugs must be used rigorously. In general, laxatives or antacids that contain magnesium should be avoided.

    If someone is prone to constipation, it is best to regulate it with a balanced, high-fiber diet.

    It is always best to ask the doctor what medications to take, even if they are over the counter. It is also necessary to take magnesium supplements only after consulting a doctor. In addition, they should be kept out of the reach of children.
