What are the dangers of iron deficiency anemia? Introduction to the dangers of iron deficiency anemia

Iron deficiency anemia is a common symptom of anemia, because the prevalence is relatively high, so patients always do not pay too much attention to their own symptoms, such as sometimes dizziness, sometimes shortness of breath, etc., these are always ignored, but iron deficiency anemia is very harmful to the body.So, what are the dangers of iron deficiency anemia?

1. Decreased immunity

Decreased immune function, particularly in cellular immunity and leukocyte phagocytosis. Therefore, adolescents with moderate iron deficiency anemia are generally less resistant to diseases, especially respiratory diseases.

2. Decreased physical strength

Iron deficiency decreases the concentration of respiratory enzymes, mitochondrial oxidase and myoglobin in bone and skeletal muscles, resulting in insufficient oxygen supply to muscles, decreased aerobic metabolism, and accumulation of lactic acid in the blood. Therefore, patients with mild iron deficiency anemia may feel fatigue and wheezing during physical exertion.

In addition, adolescents with iron deficiency anemia will have a significant decrease in muscle explosiveness, isotonic muscle strength, and more importantly, the persistence of endurance activities will also be reduced.

3. On the cardiovascular

Anemia weakens the oxygen-carrying capacity of the blood, which can endanger the function of various systems and organs in the body. It is affected to varying degrees depending on the severity and duration of anemia, the age of the patient, and the presence or absence of underlying diseases (especially heart, cerebrovascular, and lung). Among them, palpitation and shortness of breath after activity are the most common, and some patients with severe anemia can also have angina pectoris and heart failure, and there may be mild sluggishness during examination, edema of the lower limbs, and changes in electrocardiogram.

4. Intellectual development

Iron deficiency anemia can affect the development of brain cells and cause mental retardation, and this change is irreversible, that is, brain cell dystrophy in infancy and early childhood causes mental retardation, and even if you provide good nutrition when you grow up, you can't make up for the backwardness caused by this stage.

5. Harm to pregnant women

Maternal iron deficiency anemia can lead to fetal growth retardation in the mother's body, and babies can have congenital anemia after birth; Maternal iron deficiency anemia, low iron content of breast milk, insufficient nutritional iron absorption, and weak constitution, slow recovery of qi and blood.

6. Iron supplements

1. Pork liver

When it comes to iron-supplementing foods, the first choice is pork liver, which not only contains a lot of iron, but also contains a lot of protein, vitamins and folic acid. The mineral iron is the basic raw material for the human body to make hemoglobin; Vitamins B1 and B2 are good medicines for pernicious anemia; Liver glucose and vitamin A can improve the physiological regulation of the hematopoietic system in patients with anemia. Therefore, the nutrition of pork liver is very comprehensive, but it should be noted that pork liver also contains a lot of cholesterol, so it should not be eaten excessively.

2. Beef

In addition to pork liver, beef is also the best choice for iron supplementation, each 100 grams of beef contains 3.2 mg of iron, but also contains 20.1 mg of protein, people with stomach problems often eat beef in addition to iron, but also has the effect of strengthening the spleen and stomach. It should be noted that if you are giving iron to your baby, you must cook the beef thoroughly, so that the crude fiber in the beef can be completely digested and absorbed by the baby.

3. Pig kidney

Studies have found that there are 5.6 mg of iron per 100 grams of pig kidney, and the protein content is even higher, with up to 16.8 mg of protein per 100 grams of pig kidney.Of course, the nutritional value of pork kidney is not only these, but also the content of zinc, iron, copper, phosphorus, B vitamins, and vitamin C is also a lot, but you must pay attention to cleaning it before eating.

4. Pork

Pork is the most common meat on the table, and pork is particularly rich in iron, every 100 grams of pork contains 3.4 mg of iron, and pork also has a good effect of moistening the intestines and stomach, especially suitable for babies to supplement iron. It should be noted that since lard contains a lot of fat and oil, it is best to pick lean meat to eat.

5. Soybeans

Iron is not only found in meat foods, but also in vegetarian foods that contain iron, such as soy. The study found that soybeans contain 9.4 mg of iron per 100 grams, but although soybeans contain higher iron, they are slightly less absorbed than animal sources.

6. Copper-contained

People with iron deficiency anemia, especially the elderly, are often accompanied by copper deficiency in the body, copper can promote the absorption and utilization of iron, and is also an essential trace element for the human body, copper can participate in the synthesis of human blood red, and has a good hematopoietic effect.Therefore, in addition to the intake of iron-containing foods in the diet of the elderly, they should also pay attention to the intake of copper-containing foods. Foods rich in copper include liver, kidneys, hearts, oysters, fish, lean meats, beans, sesame seeds, Chinese cabbage, radish seedlings, seafood, egg yolks, raisins, tomatoes and nuts.

7. Iron supplement

The body's ability to absorb nutrients from food varies from individual to gastrointestinal. If the anemia is more severe, or the appetite is not good, and the amount of food is insufficient, it is difficult to make up for it with diet alone, and it can be supplemented with a certain amount of iron to achieve the effect of iron and blood supplementation. Oral iron should be preferred for iron supplementation, which is safe, simple, and reliable. Ordinary iron supplements can irritate the stomach and produce various side effects, and it is difficult to guarantee the safety and effect of iron supplementation. For the selection of iron supplements, the effect is good, and the taste should be easy to accept, so as not to cause nausea, vomiting and other adverse reactions.
