what cause anemia

Some these factors could cause increased risk of anemia:
1.Poor diet
Man or woman whose diet is consistently low in iron and vitamins, especially folate, is at risk of anemia. Your body needs iron, protein and vitamins to produce sufficient numbers of red blood cells.
2.Intestinal disorders.
Having an intestinal disorder that affects the absorption of nutrients in the small intestine , such as Crohn's disease and celiac disease will puts you at risk of anemia. Surgical removal of or surgery to the parts of the small intestine where nutrients are absorbed can lead to nutrient deficiencies and anemia.
3.Menstruation
Some of women are at greater risk of iron deficiency anemia than are men. That's because women lose blood — and with it, iron — each month during menstruation.Otherwise if they are pregnancy.
4.Pregnancy
The most high risk that according to me is pregnant women,because they because their iron stores have to serve the increased blood volume of the mother as well as be a source of hemoglobin for the growing fetus.It is effect to the baby growth.
5.Chronic conditions
If you have cancer, kidney or liver failure, or another chronic condition, you may be at risk of what's called anemia of chronic disease. These conditions can lead to a shortage of red blood cells. Slow, chronic blood loss from an ulcer or other source within the body can deplete your body's store of iron, leading to iron deficiency anemia.
6.Family history
Check your family medical record, If there is history of an inherited anemia, you also may be at increased risk of the condition.But you may not to worry because it doesn’t always to be happened.
7.Certain infections
Some cases , blood diseases and autoimmune disorders, exposure to toxic chemicals, and the use of some medications can affect red blood cell production and lead to anemia. Other people at risk of anemia are people with diabetes, people who are dependent on alcohol (alcohol interferes with the absorption of folic acid) and people who adhere to a strict vegetarian diet, who may not get enough iron or vitamin B-12 in their diet.
