Why does iron deficiency lead to anemia

summary

According to the current situation of economic development, according to the research, in developing countries and underdeveloped areas, infants and women of childbearing age are generally more likely to suffer from iron deficiency anemia than those in developed countries. The reason for this difference is mainly due to the lack of diet and related knowledge of people in underdeveloped areas and countries. Iron deficiency anemia is mainly associated with insufficient supplementary food for infants, partial food for adolescents, excessive menstruation / multiple pregnancies / lactation and some pathological factors. Now I will introduce in detail why you get iron deficiency anemia.

Why does iron deficiency lead to anemia

Reason 1: for infants, teenagers, pregnant and lactating women. Infants and young children need more iron because of their physical growth. If they don't supplement supplementary food with high iron content in time, it will lead to iron deficiency; if they are partial to food, they will also suffer from iron deficiency; if women have more menstruation, pregnancy or lactation, their iron demand will increase. If they don't supplement high iron food, they will also suffer from iron deficiency, and iron deficiency will eventually lead to iron deficiency anemia.

Reason 2: iron absorption disorder or malabsorption can also lead to iron deficiency anemia. In patients with gastric ulcer, due to the disorder of gastrointestinal function, the food quickly entering the body bypasses the main absorption site of iron (duodenum), which reduces iron absorption. The absorption of iron deficiency or disorder will eventually lead to iron deficiency anemia.

Reason 3: excessive blood loss can also lead to iron deficiency anemia: especially chronic blood loss is the most common and the most important reason for iron deficiency anemia. For example, excessive menstrual bleeding in women, if not timely supplement iron content, it will lead to iron deficiency anemia. In addition, chronic bleeding caused by hemorrhoids can also cause anemia.

matters needing attention

The main cause of iron deficiency anemia is that we don't pay attention to supplement the food containing iron in our daily life. For people with balanced iron content, it may not cause iron deficiency anemia, but for some growing infants, teenagers and menstrual women, supplement of iron is essential.
