What causes anemia? Causes of anemia

1. Iron is an important trace element for the human body and an indispensable factor in the hematopoietic process. Lack of iron intake in the diet is a common cause of anemia. When the human body lacks vitamin B12, it can also cause anemia. Especially among people with severe picky eaters and partial eclipses, their bodies lack iron, protein, vitamin B12 and other elements needed for hematopoiesis.

2. Some patients do not lack iron in their diet, but their body’s poor absorption and serious loss of iron can easily lead to anemia. For example, poor gastrointestinal absorption, ulcers, hemorrhoids, heavy menstrual flow, and functional uterine bleeding in women can all lead to anemia.

3. Massive blood loss in the human body can also cause anemia. Surgery, trauma and other factors are also likely to cause anemia in the body.
