What are the causes of anemia?
Causes of anemia
First, erythropoietic anemia
Why do hemolytic organs, namely bone marrow, produce fewer cells? If bone marrow is compared to a hematopoietic factory, it is easy to understand and analyze.
The first possibility is the lack of hematopoietic raw materials, mainly including iron, vitamin B 12, folic acid, vitamin B6 and protein. The second possibility is that the hematopoietic factory itself is paralyzed and stopped production, such as bone marrow being infected, poisoned, destroyed by radiation, or occupied by other cells such as tumor cells; The third possibility is the lack of "lubricant" to make the factory machines run, that is, the lack of factors to regulate erythropoiesis, such as the decrease of erythropoietin.
The common types of anemia are: iron deficiency anemia, vitamin B 12 or folic acid deficiency megaloblastic anemia, aplastic anemia, infectious anemia, lead poisoning anemia and anemia caused by tumor. But there is a special kind of anemia called "infant physiological anemia", which is a transient anemia caused by a normal physiological change 2-3 months after the baby is born. See "Infant Physiological Anemia" for details, so it is called physiological anemia.
Second, hemolytic anemia.
Under normal circumstances, the life span of red blood cells is 120 days. Every day, about 65438 0% of aged red blood cells are removed from the blood, and at the same time, a corresponding number of newborn red blood cells are released from the bone marrow into the blood to maintain a constant number of red blood cells. When the life span of red blood cells is shortened and the damage is increased, although bone marrow hematopoiesis is enhanced at this time, it is not enough to make up for the loss of red blood cells. The resulting anemia is called hemolytic anemia. Common types are: G-6-PD enzyme deficiency such as silkworm bean disease, immune hemolysis, hereditary spherocytosis, β -thalassemia and so on.
Third, hemorrhagic anemia.
As the name implies, this is anemia caused by excessive blood loss, which can be divided into acute and chronic types. Acute blood loss in children is rare, mostly long-term chronic occult blood. Hemorrhagic anemia can occur such as gastrointestinal allergy to milk, intestinal malformation, intestinal hookworm disease, birth injury such as skull hematoma and menorrhagia.
Why are women anaemic?
1, excessive slimming
"Slimming" has always been the hottest topic discussed by girls. In order to keep slim, many women go on a diet at will and take a lot of diet pills. Long-term nutritional imbalance will cause iron deficiency in the body, which is prone to iron deficiency and lead to anemia.
2, menorrhagia
Women come to menstruation once a month, and a certain amount of iron will be lost every time they have menstrual cramps. Under normal circumstances, women lose about 30 ~ 50ml of blood and about15 ~ 25mg of iron in each menstrual cycle. And if a lot of bleeding, can not maintain the balance of iron in the body, it is easy to take away a lot of iron, over time, anemia occurred.
3, often use inferior cosmetics
Frequent use of inferior cosmetics is also one of the causes of anemia in women. Through research, it is found that the lead content in inferior beauty products is high, which is easy to invade the human body, hinder the production of hemoglobin and lead to anemia over time.
4. Iron supply is insufficient during pregnancy
Pregnant women's demand for iron is nearly four times higher than that before pregnancy. Pregnant women often eat foods with low or no iron content because of nausea, vomiting, partial eclipse and anorexia. Coupled with weakened gastrointestinal peristalsis during pregnancy and lack of gastric acid, it will also affect the absorption of iron. Long-term insufficient iron intake reduces free iron and iron reserves in pregnant women.
5, iron deficiency, improper diet
First of all, anemia has a lot to do with diet. Due to climate change, such as rainy weather and physiological conditions, some people will have poor appetite or prefer some foods that suit their appetite.
Although the diet structure of China people is becoming more and more westernized, it is still dominated by plant foods, and some substances such as polyphenols will strongly inhibit the biological absorption and utilization of iron. In the long run, it will inevitably lead to iron deficiency due to too little animal food intake.
6, do not eat staple food and meat and eggs.
The consequences of not eating staple food and meat and eggs are terrible. If you don't eat meat and eggs, your body will easily lack trace elements such as protein, vitamin B 12, calcium, iron and zinc.
7. Drink tea and coffee regularly.
Coffee contains certain nutrients, and tea is also a good health care product, but you should drink it in moderation, otherwise it will go too far. Coffee contains a compound called carbolic acid, which will hinder the body's absorption of iron. Iron deficiency anemia is especially unsuitable for drinking tea. Tannic acid combined with iron in strong tea can also form insoluble matter, so that iron can be discharged with feces. Women should avoid drinking coffee and tea during menstruation.
8, fruits and vegetables, yogurt as a dinner.
Nowadays, more and more women are eating fruits, vegetables and yogurt. The oxalic acid, phytic acid, phosphoric acid and a large amount of dietary fiber contained in plants will also affect the absorption of iron, and the absorption rate is only one tenth of that of meat.
What about anemia?
Coagulated pig blood (used as food)
To improve anemia from diet, you can eat more pig blood at ordinary times. The composition of pig blood is basically the same as that of human blood, and it contains a lot of iron, which can supplement the iron that human body lacks, thus providing raw materials for human body to synthesize hemoglobin and improving the content of hemoglobin. Improve the symptoms of human hypoxia.
spinach
To improve anemia from diet, eat more spinach at ordinary times. Spinach is also rich in iron, which can provide us with the iron we need, thus promoting the synthesis of hemoglobin and improving the symptoms of hypoxia. In addition, spinach also contains some vitamins and trace elements, which is very beneficial to human health.
(edible) auricularia auricula
To improve anemia from the diet, usually eat more auricularia auricula, which is also rich in iron, which can promote the synthesis of hemoglobin and improve the symptoms of hypoxia. Auricularia auricula is a kind of fungus food, which is not only delicious, but also contains many vitamins and trace elements needed by human body, which is inseparable from our healthy diet.
Fruits and vegetables
In addition, you should eat more fruits and vegetables rich in vitamin C, such as kiwi fruit, jujube, strawberry, apple, orange, amaranth, pepper, bamboo leaf green, cauliflower and so on. These foods are rich in vitamin C, which can promote the absorption of iron, promote the synthesis of hemoglobin and improve the symptoms of hypoxia.
iron wok
When we usually cook, we'd better use an iron pot, which contains iron. If we often cook in an iron pan, iron will unconsciously enter our bodies, silently promote the synthesis of hemoglobin in our bodies, improve the ischemic symptoms of our bodies, and play an escort role for our health.
