When the body’s demand and supply of iron are out of balance, the iron storage in the body is depleted, followed by a lack of iron in the red blood cells, which eventually leads to iron-deficiency anemia. IDA is the final stage of iron deficiency, manifesting as microcytic hypochromic anemia and other abnormalities caused by iron deficiency.What are the main causes of iron deficiency anemia?
Causes of iron deficiency anemia?
1. Increased iron requirements and insufficient iron intake:
more common in infants, adolescents, pregnant and lactating women. Infants and young children need more iron. If they do not supplement foods with high iron content such as eggs and meat, it is easy to cause iron deficiency. Adolescents are prone to iron deficiency. Women with increased menstruation, pregnancy or breastfeeding increase their iron requirements. If high-iron foods are not supplemented, IDA is likely to occur.
2. Iron absorption disorder:
Commonly seen after subtotal gastrectomy, gastric acid secretion is insufficient and food quickly enters the jejunum, bypassing the main absorption site of iron (duodenum), reducing iron absorption. In addition, gastrointestinal dysfunction caused by a variety of reasons, such as long-term unexplained diarrhea, chronic enteritis, Crohn’s disease, etc., can cause IDA due to iron absorption disorders.
3. Excessive iron loss:
Chronic long-term iron loss without correction results in IDA. Such as: chronic gastrointestinal blood loss (including hemorrhoids, gastroduodenal ulcers, hiatal hernia, gastrointestinal polyps, gastrointestinal tumors, parasitic infections, rupture of esophageal/gastric varices, etc.), menorrhagia ( Intrauterine placement, uterine fibroids, menstrual disorders and other gynecological diseases),
hemoptysis and alveolar hemorrhage (pulmonary hemosiderosis, pulmonary hemorrhage-nephritic syndrome, tuberculosis, bronchiectasis, lung cancer, etc.), hemoglobinuria (array nocturnal hemoglobinuria, cold antibody autoimmune hemolysis, cardiac prosthetic valve, marching hemoglobinuria, etc.) and others (hereditary hemorrhagic telangiectasia, chronic renal failure, hemodialysis, multiple blood donations, etc.) .
Iron deficiency anemia contraindications
1. Because the polyphenols in coffee easily form salts that are difficult to decompose with iron, which inhibits the absorption of iron, the tannic acid in tea will combine with iron to form insoluble iron tannate, which is normally absorbed by the Zuoan Metro , For patients with iron deficiency anemia, coffee and strong tea are not suitable for drinking.
2. Eating too much fat will inhibit the body’s hematopoietic function, and at the same time, too much fat will also affect the digestion and absorption ability of patients with iron-deficiency anemia. The daily intake of fat should not exceed 70 grams. About 50 grams is appropriate, it is best to choose edible vegetable oil esters.
3. It is not advisable to drink milk when taking iron-supplementing drugs, because calcium and phosphorus in milk are easily combined with iron to form insoluble iron-containing compounds, which will significantly reduce the absorption rate of iron. The supplement absorption rate of the tablet is relatively high and will not be affected by dietary factors.
4. Garlic is spicy and warm in nature. Eating too much is easy to cause liver blood deficiency, affecting the absorption of vitamin N, the absorption and utilization rate of iron will be significantly reduced, and the excretion rate of iron will be significantly increased. The volatile component of garlic, allicin, It will reduce the red blood cells and hemoglobin in the blood, and eating garlic for a long time will lead to anemia.
5. The human body is an environment of acid-base balance. If the body presents an alkaline environment, it is not conducive to the reduction and absorption of iron. The lack of gastric acid will directly affect the free and transformation of iron in food. There are as few patients with iron deficiency anemia as possible. Eat alkaline foods.
What to eat for iron deficiency anemia
1. Eat beef
As we all know, beef is high in nutrients, including iron content is good, and it is also rich in protein. If you eat beef regularly, you can not only supplement iron, but also strengthen the spleen and stomach. Therefore, for women with iron deficiency anemia, it is very good to eat more beef.
2. Eat pork liver
What to eat to make up for iron deficiency anemia fast? Pig liver is also a very good food for iron supplement. It is not only high in iron, but also contains phosphorus and protein.
3. Eat black fungus
In fact, there are many foods that can improve iron-deficiency anemia. Among them, black fungus is also a very good recommendation, because it is a natural iron-replenishing food with high iron content. King” title.
4. Eat raisins
Raisins are high in iron and calcium, so it is a good tonic for children, women and those with anemia. medicine also believes that raisins have the effect of nourishing blood and qi and warming the kidneys, and eating them regularly can improve the symptoms of anemia.
5. Eat longan
Longan is rich in glucose, sucrose and protein, etc., and the iron content is relatively high. It can not only increase heat energy and supplement nutrition, but also promote the regeneration of hemoglobin, so as to achieve the effect of replenishing blood.What are the main causes of iron deficiency anemia?
