The role of magnesium in the body is the norm in the blood decrease and its symptoms how to

A person with magnesium deficiency is nervous, constantly tired, with poor memory and concentration. Often it is scattered on a large number of cases, not bringing them to the end. Consultation with a psychologist does not render any benefit in this case. And the reason is just a lack of magnesium. Magnesium deficiency also affects the condition of the skin, hair and nails.

The list of symptoms of magnesium deficiency can be quite extensive, but the most common symptoms are listed below.

1. Irregular heart rhythm, which can be expressed in premature atrial contractions (extra strokes), ventricular extrasystole (missed heartbeats), atrial fibrillation (irregular heart rhythm), and tachycardia (heart rate).

2. Coronary spasms, ie, temporary, sudden narrowing of the coronary artery as a result of slowing or stopping blood flow.

3. Tingling and numbness of the extremities due to the effects of magnesium deficiency on the peripheral nervous system.

4. Muscle cramps (more severe than in the early stages of deficiency).

5. Personality changes, such as irritability, tantrums, panic attacks, depression.

6. Chronic insomnia and other sleep disorders.

8. Impaired renal function.

If you suspect that you may have magnesium deficiency, you can take a special medical test. A blood serum test is the most common test, but by no means the most accurate. Instead, you can ask your doctor to prescribe a Magnesium RBC test, which can measure the amount of magnesium directly in the cells.

If the magnesium content in the blood to the norm is not enough, then various symptoms and conditions may develop:

  • Redness, discomfort, and scabies.
  • Partial or complete numbness of the arms and legs.
  • Convulsive condition.
  • Short temper.
  • Complete indifference to what is happening.
  • Fast fatiguability.
  • Neurasthenia.
  • Loss of appetite.
  • Insomnia.
  • Unreasonable mood swings.
  • High pressure.
  • Hard bowel movement.
  • Impaired adrenal glands.
  • The appearance of urolithiasis or gallstone diseases.
  • Diabetes.
  • Weakness of the immune system.
  • Precancerous condition.

Above is a complete list of abnormalities that may occur as a result of magnesium deficiency in the body. Symptoms in women appear in the same way as in men, but against the background of the menstrual cycle or menopause, all changes can be much more intense, which creates an additional threat to the woman’s health.

It should be noted that a lack of magnesium in a pregnant woman threatens the development of toxicosis in the late stages, early childbirth or miscarriage. That is why you should react very seriously to any ailments. Also, the lack of this element can lead to heart ailments, nervous breakdowns and gastrointestinal diseases, which will adversely affect the process of gestation.

For children

As we see from the list above, it is impossible to overestimate the role of magnesium in the human body. It is especially important to monitor the norm of this indicator in young children. Their body is still very weak and needs its basic building material. If the parent observes any discomfort in the child, it is important to undergo a full examination with doctors to identify the root causes.

In children, the norm is completely different.

No need to be afraid and postpone the trip to the hospital. It is easy to deal with deviations from the norm, the main thing is to detect this problem at the very beginning. Do not resort to self-medication and listen to the advice of strangers, as well as those who claim to know better than a doctor. Especially beware of those who allegedly had such a problem and will gladly help you solve it.

Very often they operate with complex terms – paresthesia and tetany, which are very scary for people not related to medicine. In fact, there is nothing terrible in these terms. The first means a violation of sensitivity, which is manifested by tingling, itching, goosebumps, numbness, coolness. We talked about all these symptoms above.

You can replenish the reserves of this important element by adjusting your diet. It should be rich in those foods that contain a lot of magnesium.

Where to get magnesium

In addition to consuming more foods rich in magnesium – greens, cabbage, broccoli, nuts, legumes, and limiting the diet or completely avoiding refined sugar, non-alcoholic caffeinated drinks and alcohol, animal proteins and fats, you can also take drugs and dietary supplements with magnesium.

Since magnesium must be in the form of salt in order to be absorbed by the body, on the packaging of the drugs you will see names such as magnesium citrate, magnesium asparaginate, magnesium glycinate and others. An effective combination of magnesium preparations with B vitamins, especially B6, since it facilitates the penetration of magnesium ions into cells.

It is important to note that magnesium oxide is not absorbed by the body and can cause diarrhea. The addition of magnesium to the diet should be balanced by the intake of foods rich in calcium, vitamin K2, and vitamin D must be obtained in the body. All substances must be in a certain balance.

It is useful to conduct a personal “inventory” and assess the likelihood of suffering from a lack of magnesium. Corrective measures are always at hand – in any pharmacy. Dietary adjustment is also a surefire aid in controlling the symptoms of magnesium deficiency.


Another name is hypomagnesemia. This ailment can develop in both women and men for a number of reasons, which we will consider below:

  • Disturbed exchange of magnesium in the blood.
  • Weak resistance to stress.
  • Abuse of diuretic teas that remove the necessary macronutrients.
  • Violations in the production of insulin.
  • Taking antibiotics for a long time without the supervision of a doctor.
  • Intestinal dysbiosis.
  • Any kind of nutrition based on injection into a vein.
  • Macroelement processing dysfunction.


Elevated levels of magnesium in the blood are called hypermagnesemia. This situation is not as dangerous as a deficiency of this macrocell, but you should consult a doctor. It is important to know that according to medical statistics such deviations never end in death.

In a healthy body, as a rule, the normal content of magnesium in the blood is observed. That is why we consider the factors that in one way or another affect the deviations from it:

  • Arthritis.
  • Psoriasis.
  • Failure of magnesium metabolism.
  • The abundance of medicines and foods saturated with magnesium.
  • Hyperfunction of the thyroid gland.
  • Dyslexia.


How to determine before a blood test whether there are signs of oversupply? To do this, you should carefully consider your body, since evidence of hypermagnesemia can be:

  • Increased drowsiness.
  • Apathy.
  • Fatigue.
  • General lethargy.
  • A sharp decrease in performance.
  • Impotence, accompanied by acute headaches and dizziness.

To prevent this situation, it is important to be very attentive to your health and check with your doctors what drugs they prescribe for you. You should never engage in self-medication, because you can develop additional complications, which will be even more difficult to treat.

The role of magnesium in the body of a woman

We found out what the deviation from the norm leads to, and especially the deficiency of magnesium in the body. Symptoms in women are similar to those in the male population, but the importance of magnesium for the fairer sex is much higher. This follows from the fact that magnesium in a woman has an important function – it normalizes the hormonal background, which guarantees a systematic menstrual cycle. This allows ovulation to come on time, and get the opportunity to conceive a child.

The magnesium content in the blood is the most important indicator for a lady preparing to become a mother. A woman, when bearing a fetus, loses many useful substances, therefore, she needs thorough support. Since all the vitamins come to the baby from the mother’s body, the woman needs to nourish the body from external sources. At the moment, magnesium is very popular in tablets. It is absolutely harmless, but without the supervision of a doctor, it should not be taken.

It is important to note that the lack of this trace element in the mother can affect the condition of the baby. That is why the attending physician very often prescribes magnesium to the expectant mothers in tablets. However, all this is done only after a blood test is received. A girl should know that she needs to give up diuretic teas so that she can not contribute to the withdrawal of magnesium.

What to eat

If for some reason you need to consume a significant amount of liquid, you should take care to replenish the Mg supply in a timely manner. This can be done by eating foods in which the magnesium content is high:

The listed products should be consumed 30-60 minutes before a meal in order to get the best effect. You can drink medicines with water. Standard treatment lasts about 2 months. It should also be borne in mind that magnesium in tablets, like other medicines, can cause side effects. Most often, they are manifested by allergies and pathologies of the stomach.

How to prepare for blood donation

As we already know, the role of magnesium is very large. To obtain information, the patient is sent for a blood test for magnesium. The biomaterial is taken on an empty stomach in the morning. Blood is taken from a vein. To get the most reliable results, you should prepare your body. Remember that in the morning you can’t eat. It is better to go to bed before midnight on the day of collecting the biomaterial.

It is also worth the day before completely stop playing sports and not do hard work. Even if you are a heavy smoker, try to live without tobacco for two hours before the procedure. Also, for a week you must completely forbid yourself alcoholic beverages and not take medications, which include magnesium.
