What is iron deficiency anemia:

Anemia includes many types, such as giant red blood cell anemia, regenerative disorder anemia, hemalded anemia, and iron deficiency anemia, and iron deficiency anemia; therefore, iron deficiency anemia is determined by the World Health Organization (WHO) as the worldOne of the lack of sexual nutrition.

Iron deficiency anemia, as the name suggests, is caused by the lack of trace element iron, and the reduction of red blood cells in the blood in the blood is a kind of nutritional deficiency.

Causes of iron deficiency anemia:

3. Gastrointestinal diseases, such as atrophic gastritis, gastric ulcers, and lack of gastric acid, such as the absorption of iron, which will also cause iron deficiency.

4. In order to treat acid -resistant drugs for gastric disease, gastric acid is neutralized and affects the digestive function, resulting in reduced iron absorption.

5. Patients with gastric resection, diarrhea, enteritis and other diseases increase the consumption of iron. Excessive bleeding from trauma will increase the symptoms of iron deficiency anemia.

The role of iron: iron and protein constitute hemoglobin (red blood cells), and hemoglobin is responsible for transporting oxygen and carbon dioxide in the body.

Symptoms of iron deficiency anemia:

1. The symptoms of anemia are directly related to the severity of anemia. In the early stage, fatigue, panic, shortness of breath, dizziness, and even motion sickness, slower blood flow becomes cold, and the severe complexion is pale, pale and liter of the liver and spleenSymptoms such as swelling.The most serious anemia heart disease is prone to left heart failure.

You can choose foods with rich vitamin C content, such as jujube, citrus, kiwi, fresh dates, pepper, tomato, carrot, etc.

4. Tyrum -divided heme iron and non -heme iron in food. Animal food contains mainly hemoglobin iron, with high absorption and utilization rate.Multuteic acid and acid -implyry acid affect the absorption of iron. It is relatively low in absorption or utilization. Like the red dates, spinach, wolfberry, etc. we often mention, it does not play a role in iron supplementation.

The most abundant iron containing foods in foods are animal blood and animal liver, followed by lean meat, egg yolk, animal kidneys, etc.; Plant -based iron containing soybean, black fungus, sesame sauce, dried fruit, etc.
