1⒈ loss of appetite and other gastrointestinal symptoms. The patient's diet decline, taste abnormalities, often like to eat dirt, beans, paper and other abnormal symptoms, medically known as "heterophilia".

Peake growth stagnation, short stature, like a dwarf. Zinc deficiency can also cause bone abnormalities, manifested by inflammatory changes in the joints of the lower limbs.

Adolescents and young people with zinc deficiency may have slow sexual development, delayed sexual maturity, and infantile sex organs. Sexual function decreases, sperm decreases, secondary sexual characteristics are underdeveloped, menstruation is not normal or stops, and there is no fertility.

Sung zinc deficiency can lead to anemia, slow wound healing, rough skin, dermatitis of the extremities, and susceptibility to colds. Zinc deficiency in pregnant women can even cause fetal malformation.

Be careful with zinc deficiency, many organs in the human body and blood zinc content has decreased, even the zinc content of the hair also decreased, therefore, the zinc content of the hair can be used as one of the indicators to determine whether the body of zinc deficiency. At present, some hospitals, medical schools, research institutes and other medical units are able to measure and evaluate zinc.

Supplementation of zinc methods:

⒈ adjust the dietary structure, a reasonable combination of food, reasonably cooked food, do not favoritism, less snacking, eat more zinc-rich foods. Generally speaking, animal food physics zinc content than plant food content is high, seafood zinc content is also high. Foods containing zinc from high to low in the following order: seafood, animal foods, legumes and cereals, fruits and vegetables, some of the higher zinc-containing foods are: oysters, malt, yeast, beef, lean pork, pork liver, tea, cheese, kelp, peanut butter, chicken, soybeans, flour and so on. Animal foods are not only high in zinc, but also have a relatively high absorption rate. For example, the absorption rate of zinc in meat is as high as 30% to 40%, while the absorption rate of plant foods is generally only 10% to 20%. Therefore, when evaluating the nutritional value of a food, not only the zinc content but also its absorption rate should be considered. Seafood, seaweeds such as kelp, seaweed, also contains high levels of zinc, a variety of plant foods, beans, nuts contain more zinc, vegetables to cabbage, radish, eggplant in the high content. From the nutritional point of view of zinc, the more fine processing of cereals, zinc and nutrient loss is also higher, it has been determined that the zinc content of refined white flour is only wheat 1/4. In addition, oxalic acid, phytic acid in vegetables will also inhibit the absorption of zinc. Of course, zinc-rich foods to eat often, but also can not eat too much, which not only causes waste, some will also cause zinc poisoning, especially some pregnant women eat a large number of continuous consumption of a variety of animal livers, and cause poisoning. In addition to 1 or more times a large number of zinc preparations can also produce poisoning.

Peake serious zinc deficiency patients should go to the hospital in time. Currently used zinc preparations are zinc sulfate, zinc acetate, zinc oxide, zinc orotate-arginine, zinc glycyrrhizate and zinc gluconate. Zinc gluconate is the most commonly used zinc preparation because it is effective and has fewer side effects. The therapeutic concentration should be physiologic. The therapeutic dose is not standardized, generally do not take more than 120 mg of zinc ions per day orally, and should not be taken for a long time, in order to prevent poisoning.
