Many patients will be confused after being told that they are anemic, so why are they anemic? Now, Director Huang from Beijing Chaoyang Hospital affiliated to Capital Medical University will explain it to you.

There are many causes of anemia. We classify anemia according to its cause and pathogenesis. First, the patient has insufficient hematopoietic raw materials. The hematopoietic raw materials produced by our red blood cells are mainly iron, folic acid, and B12. Our bone marrow is a hematopoietic organ. If the hematopoietic function of the bone marrow is normal, anemia will occur if there is insufficient hematopoietic raw materials. For example, patients who have undergone partial gastrectomy, children in the vigorous growth period, pregnant women, and lactating women. Second, there is a problem with the hematopoietic machine, such as aplastic anemia. That is to say, if the bone marrow itself becomes diseased and the hematopoietic function decreases, aplastic anemia will also occur. In addition, the hematopoietic machine is normal and the hematopoietic raw materials are also normal, but due to some reasons the body is hemolyzed and the red blood cells are dissolved. At this time, the patient will also develop anemia. Third, tumor-related anemia. Everyone is very familiar with anemia. It is a very common symptom. Many people think that anemia only occurs in women, but in fact it is not. Anemia also occurs in many men. People with anemia generally experience symptoms such as drowsiness, fatigue, dizziness, and pale complexion. Many factors can cause anemia symptoms in the human body.

Anemia is a common symptom in which the volume of red blood cells in the peripheral blood of the human body is reduced and is lower than the normal value. Patients with anemia generally experience symptoms such as fatigue, headache, insomnia, and memory loss. There are many causes of anemia. The treatment of anemia needs to determine the cause before prescribing the right medicine.

1. Disease

Reduced red blood cell production is the main cause of anemia. The reduction of red blood cells will lead to the weakening of the hematopoietic function of the bone marrow, thus causing anemia.

2. Chronic blood loss

If a woman has heavy menstruation during her menstrual period, it may lead to iron deficiency and anemia. Generally speaking, a woman’s menstrual cycle is about one month and lasts for 5 months. ~7 days, the volume of menstrual blood is about 30 ml. From a medical point of view, if the menstrual blood volume is higher than 80 ml and lasts for more than 7 days, it can be determined as menorrhagia. Menorrhagia is likely to cause chronic blood loss. Chronic blood loss is the main cause of anemia. .

3. Iron deficiency during pregnancy

During pregnancy, the body needs much more iron than usual. This is mainly because the gastrointestinal motility of pregnant women will slow down during pregnancy, resulting in a lack of gastric acid. Iron absorption is poor, and long-term insufficient iron intake can lead to anemia, and in severe cases, fetal health may be threatened.

4. Long-term strenuous exercise

Sweat contains a lot of iron. When you sweat a lot during long-term strenuous exercise, it will lead to excessive iron loss. And after strenuous exercise, red blood cells will be damaged, and muscles will also be damaged to a certain extent, which will cause the loss of iron, leading to anemia.

5. Irregular life

When the human body is under great mental and work pressure, excessive physical exertion, decreased sleep quality, etc. will occur. The health of the body is threatened, and the human body's response to Decreased iron absorption can also cause anemia.

6. Diet

If you have a partial or picky eating habit in your life, or do not like to eat meat, iron absorption will be affected, and iron deficiency will occur in the long run. This in turn causes anemia.

To sum up, everyone already has a certain understanding of the causes of anemia. In order to avoid anemia, friends can pay attention to the above six points in life and nip it in the bud. Friends who have been diagnosed with anemia can eat as many blood-rich foods as possible. At the same time, during special circumstances such as menstruation and pregnancy, they should pay more attention to diet and rest. If the situation is serious, they should be treated in time to avoid aggravation of the condition.
