Zinc is an important nutrient element, which stands onsecond only to iron in importance to the human body and is involved in all processes that provide its vital functions.

For better absorption of zinc by the body needs vitamins A and B6.In turn hinder the process elements such as copper, manganese, tin, iron, lead, cadmium, large doses of calcium and folic acid.

cause of zinc deficiency may be an increased intake of phosphates, phytates, taking anabolic steroids, oral contraceptives, immunosuppressants, diuretics, and frequent use of alcohol.At the same time stimulates the absorption of zinc and vitamin E deficiency may cause vitamin A, copper, and iron.

The adult body contains on average from 1.5 to 3 g zinc.It is mainly accumulated in the skin, bone, hair and semen.In normal doses, it is vital for the human body, because actually provides a lot of critical processes.

Thus, zinc in normal am

ounts:

  • regulates the nervous system (together with group B vitamins improves attention, memory, mood, and normalizes the function of the cerebellum);
  • has a beneficial effect on the immune system by increasing the protective activity of neutrophils and macrophages, ensures the production of antibodies, and also helps to remove carbon dioxide);
  • affect the course of pregnancy the process, because it reduces the risk of miscarriage and fetal growth retardation, as well as regulates the estrogen-dependent processes in a woman's body;
  • regulates the sexual glands, increasing the production of sex hormones and increasing the activity of sperm;
  • extremely important for normal development, growth and sexual maturation of an organism;
  • conjunction with vitamin A is responsible for the sense of smell, visual acuity, taste perception;
  • speeding up fat oxidation, normalizes fat metabolism in the body, and normalizes blood sugar levels;
  • is very important for normal growth of hair and nails, as well as in wound healing;
  • by synthesis of a number of digestive enzymes, normalizes digestion;
  • required for the synthesis of nucleic acids;
  • has antioxidant properties, as well as enhances the action of other antioxidants;
  • participates in hematopoiesis processes.

Zinc oxide is a drug substance which is used as an antiseptic and anti-inflammatory agent.A zinc salt used in dermatology.

difficult to overestimate the role of zinc for proper functioning of the human body, so its deficiency, as well as the excess, a very negative impact on health.According to scientific data of the daily body's need for zinc is 8 to 25 mg per day.In turn, prolonged ingestion of high doses of zinc can cause a number of adverse effects.For example, the toxicity threshold for this trace element is 600 mg / day, and a lethal dose - 1 g

Causes of excess zinc in the body

As pointed out by experts, even completely unbalanced diet can provoke a significant excess of zinc.Often excess of the normal concentration caused by taking drugs, and dietary supplements that contain zinc in their composition.It has been established that the signs of apparent excess of zinc observed in patients who took more than 150 mg of trace elements in the day.

In some cases, the danger may be the packaging of certain beverages and foods, which promotes the formation of highly toxic zinc compounds, such as sulfates, chlorides and oxides.Thus, the recorded cases of zinc poisoning resulting from eating food that has been stored in a zinc or galvanized containers.Often zinc poisoning and its compounds may occur in the workplace.Sulfate, oxide and zinc chloride are used for glass, in the manufacture of ceramics, matches, in the manufacture of artificial fibers, zinc paints, dental cement, soldering in the pulp and paper industry, and so on. G. Typically, excess zinc in the form of dust andsolid state relatively not dangerous.They are extremely dangerous compounds of the trace elements, which cause acute poisoning or chronic excess of zinc in turn.

Symptoms of excess zinc

mainly acute intoxication provoked by taking fairly large doses of trace elements.In this case, the symptoms of excess zinc in humans appear quite quickly.As a result, there are such manifestations:

  • nausea and vomiting;
  • thirst, sweet taste in the mouth;
  • asphyxia, respiratory failure;
  • decrease in immune system function;
  • gastric mucosal erosion;
  • oppressive chest pain, dry cough;
  • chills, drowsiness;
  • copper deficiency, iron, cadmium and manganese;
  • men - decreased ability to fertilize.

In case of inhalation of zinc vapor occurs fume fever, which has symptoms such as:

  • metallic taste in the mouth;
  • burns gastrointestinal mucosa;
  • abdominal pain, nausea;
  • vomiting and diarrhea;
  • drop in blood pressure;
  • occurrence of cramps in the calf muscles;
  • phenomena pharyngitis or bronchitis;
  • enlargement and tenderness of the liver;
  • conjunctival hyperemia and face;
  • chills and fever up to 39-40 ° C

In addition, dangerous symptom of excess zinc in the body is a fibrous degeneration of the pancreas.Also, quite often higher than in blood glucose.

Chronic toxicity data trace element can cause a deterioration of the condition of the skin, nails, hair loss, weakening of the functions of the prostate and pancreas and liver.Also, when zinc toxicity affected the immune system, which becomes the cause of autoimmune diseases (systemic lupus erythematosus, rheumatoid arthritis, thyroiditis, and so on. D.).

Chronic excess zinc uptake from food such minerals is significantly reduced as copper, manganese and iron, so there is a shortage of secondary.As a result, reduction of mineralization in people with excess zinc in the body there is a slowdown in the growth of bones, weakening of the tendon reflexes, and progressive weakness.In addition, to date there is evidence of a carcinogenic effect of zinc and its compounds on the human body.

Treatment In case of acute and chronic excess of zinc is important to have a person to medical care.Treatment is mainly aimed at addressing the symptoms of excess zinc.It is advisable to carry out the treatment in a hospital.

As an antidote used unitiol.Also, your doctor may prescribe sodium thiosulfate, acetylsalicylic acid, expectorants, bronchodilators, penicillamine.It is also recommended to stop taking the drugs and the use of zinc-containing zinc utensils.

When a metallic taste in the mouth, as well as a sharp increase in body temperature after exposure to zinc vapor is necessary to call emergency medical care.

As for the chronic excess of zinc, an important role is given to prevention.
