1, immune decline
Decline in immune function, especially in cellular immunity and leukocyte phagocytosis. Therefore, more than moderate iron deficiency anemia adolescents, on the disease, especially respiratory diseases, resistance is generally lower.
2, physical decline
Iron deficiency makes the respiratory enzymes, mitochondrial oxidase and myoglobin concentration in the osteoskeletal muscles are decreased, resulting in insufficient muscle oxygen supply, aerobic metabolism, lactic acid buildup in the blood. Therefore, mild iron deficiency anemia patients with physical labor will feel weak, shortness of breath.
In addition, iron deficiency anemia teenager will muscle explosive force, isotonic muscle force, etc. significantly reduced, more importantly, the endurance of endurance activities also decreased.
3, on the cardiovascular
Anemia when the blood oxygen-carrying capacity is weakened, can make the whole body system organ function is jeopardized. According to the degree of anemia and the duration of time, the patient's age and the presence of underlying diseases (especially heart, cerebrovascular, lung) and have different degrees of influence. Among them, panic after activity, shortness of breath is the most common, some patients with severe anemia can also be angina pectoris, heart failure, examination can have a mild scary sound, lower limb edema, electrocardiogram changes.
4, intellectual development
Iron deficiency anemia can affect the development of brain cells caused by intellectual backwardness, and this change is irreversible, that is, infants and young children with brain cell malnutrition caused by intellectual backwardness, grow up, even if the provision of even better nutrition can not make up for the backwardness caused by this stage.
5, pregnant women harm
Maternal iron deficiency anemia can lead to fetal development in the mother's body is delayed, after the birth of the baby can have congenital anemia; maternal iron deficiency anemia, breast milk iron content is low in iron absorption of the baby nutritional iron deficiency, their own physical weakness, the recovery of qi and blood slower.
6, iron food
1, pig liver
Talking about iron food, the first choice is pig liver, pig liver not only contains a lot of iron, but also contains a lot of protein, vitamins and folic acid and other substances. The mineral iron is the basic raw material for the human body to manufacture hemoglobin; vitamin B1, B2 is a good medicine for the treatment of pernicious anemia; hepatic sugar and vitamin A can improve the physiological regulation of hematopoietic system in patients with anemia. Therefore, the nutrition of pig liver is very comprehensive, but it should be noted that pig liver also contains a lot of cholesterol, so you can not eat too much.
2, beef
In addition to pig liver, beef is also the best choice for iron, every hundred grams of beef contains 3.2 mg of iron, but also contains 20.1 mg of protein, people with gastric problems often eat beef in addition to iron, there is also the effect of strengthening the spleen and stomach. It should be noted that, if it is for small children to supplement iron, be sure to cook the beef thoroughly boiled, so that the crude fiber in the beef is completely digested and absorbed by the baby.
3, pig kidney
Research has found that in every 100 grams of pig kidney contains 5.6 mg of iron, and protein content is higher, every 100 grams of pig kidney has up to 16.8 mg of protein. Of course, the nutritional value of pig kidney is not only these, zinc, iron, copper, phosphorus, b vitamins, vitamin C content is also quite a lot, but before eating must pay attention to clean.
4, pork
Pork is the most common meat on the table, and pork is particularly rich in iron, every hundred grams of pork contains 3.4 mg of iron, and pork is also very good laxative stomach effect, especially suitable for babies to eat iron. It should be noted that, because the lard contains a lot of fat and grease, so it is best to pick lean meat to eat.
5, soybeans
Iron is not only only in the meat food, in the vegetarian diet also has the existence of iron-containing food, such as soybeans. Studies have found that every 100 grams of soybeans contain 9.4 milligrams of iron, but while soybeans contain a higher level of iron, the absorption rate of iron from animal sources is slightly worse.
6, copper
People with iron deficiency anemia, especially the elderly body iron deficiency is often accompanied by a lack of copper, copper can promote the absorption and utilization of iron, but also the body's essential trace elements, copper can participate in the synthesis of human blood red, have a good hematopoietic effect. Therefore, in addition to the intake of iron-containing foods in the diet of the elderly also pay attention to the intake of copper-containing foods. Copper-rich foods include animal liver, kidney, heart, oysters, fish, lean meat, beans, sesame seeds, cabbage, radish seedlings, seafood, egg yolk, raisins, tomatoes and nuts.
7, iron
The body's ability to absorb nutrients from food varies depending on the individual's intestines. If the anemia is more serious, or poor appetite, insufficient meals, diet alone is difficult to make up, can be supplemented with taking a certain amount of iron to achieve the effect of iron and blood. Iron supplementation should be preferred to oral iron, safe, easy to implement and reliable efficacy. Ordinary iron will stimulate the stomach and intestines to produce a variety of side effects, safety and iron effect is difficult to guarantee. For the choice of iron supplements, the effect is a prerequisite, the taste is also easy to accept, so as not to cause nausea, vomiting and other adverse reactions.
