Magnesium deficiency

Symptoms of magnesium deficiency are irritability, personality changes, anorexia, body weakness, fatigue, dizziness, vertigo, insomnia, allergies, anxiety, convulsions (muscle spasms), the appearance of nervousness, tremor, twitching and messing tongue, involuntary eye movements, unsteady gait, abnormal heartbeat, low blood sugar levels and the occurrence of muscle contraction. In the absence of higher amounts of magnesium it also comes to hair loss, swollen gums and damage to the arteries that resemble atherosclerosis.

Magnesium deficiency is not rare and affects all body tissues. If the food has a lot of calcium, proteins and phosphate it will decrease the absorption of magnesium from the gut. To reduced absorption of magnesium may occur in cases of chronic diarrhea of any cause, poor diet in terms of protein and calories as well as in cases of severe inflammation in the body, difficult operations, disorders in the absorption of magnesium, hormonal disorders, cancer, pregnancy and in cases where the organism is under physical conditions. If someone suddenly stop hunger by providing proteins and carbohydrates without cofactors such as thiamine and Mg 2+ it may result in metabolic and neurological disorders. In chronic renal failure, the need for magnesium is reduced, while in cases of renal acidosis and diabetes mellitus large losses of magnesium are caused. There are increased level of magnesium needed in women who are breastfeeding.

Intake of large amounts of phosphate, calcium, vitamin D, and saturated fatty acids also leads to a magnesium deficiency.

Magnesium deficiency is most common in people who eat canned food in large quantities, alcoholics and people who have problems with absorption. Also, this problem occurs in the elderly.

Inadequate magnesium intake leads to the following disorders:

  • Cardiovascular disease including atherosclerosis, myocardial infarction, angina, ischemic heart disease, cardiac arrhythmias, and hypertension.
  • Diabetes. Magnesium deficiency leads to reduced insulin secretion and reduced tissue sensitivity to insulin. In diabetic women during pregnancy magnesium deficiency can significantly increase the risk of miscarriage or difficulties in childbirth.
  • Osteoporosis. Magnesium is important for the normal functioning of the bones. In addition, its role is in the functioning of the parathyroid glands, the metabolism of vitamin D and adequate sensitivity of bones to parathyroid hormone and vitamin D.
  • Migraines. Magnesium deficiency affects neurotransmitters, blood vessels and muscles of the head and neck.
  • Premenstrual syndrome. Changes the balance of calcium and magnesium due to hormonal fluctuations. It affects the levels of neurotransmitters and leads to premenstrual symptoms.
  • Asthma. Insufficient levels of magnesium in the body is associated with reduced lung function, bronchial hyperactivity and difficulty breathing.
  • Kidney stones.
  • HIV / AIDS. Magnesium deficiency has been observed in the initial stages of the appearance of HIV infection and leads to the appearance of fatigue, lethargy and mental weakness.
  • Lack of energy. People with magnesium deficiency during heavy physical exertion consume more energy than people who do not have a deficiency of this mineral.
  • Gastric tumor.


If renal function is normal there will not be poisoning with magnesium as the body ejects any excess of it. In patients with kidney failure magnesium overdose co be an important medical problem. In the hypermagnesiemia the toxicity is manifested in depressive effects of magnesium on the nervous system. Other symptoms include: diarrhea, flushing of the skin, thirst, low blood pressure, loss of reflexes, lethargy, weakness of the body, hold your fluids in the body, nausea, vomiting, shallow breathing.
