Different Types of Anemia

A few readers wrote to us recently to ask about anemia. One reader, in particular, wondered why his doctor diagnosed him with anemia when his iron level fell within the normal range. I would like to take this opportunity to address different types of diet-related anemia.

Despite the fact that different forms of anemia have different causes, they all share similar symptoms. Common signs and symptoms of anemia include:

* feeling tired or weak
* difficulty in breathing
* feeling dizzy
* inability to concentrate


Different Types of Anemia - Iron Deficiency Anemia

Iron Deficiency Anemia is the most common form of anemia, particularly among pregnant women. There are many causes for this type of anemia such as increased iron needs during pregnancy, chronic blood loss and low iron intake from diet.

The recommended iron intake for men and post-menopausal women is 8 milligrams. The recommended intake for pre-menopausal women is 18 mg, and the recommendation increases to 27 mg for pregnant women. If you are a vegetarian, the requirement for iron increases because of the low absorption level of non-heme iron present in vegetable source. According to the Dietary Reference Intake report, it is suggested that iron requirement for vegetarians is two times greater than non-vegetarians.

Folate Deficiency Anemia

Folate, or folic acid, is a type of B vitamin that is important in the formation of healthy blood cells. This type of anemia is common in older adults, heavy drinkers, pregnant women and people suffering from certain medical conditions such as sickle cell anemia.

Folate is found in dark green leafy vegetables, enriched breakfast cereals, beans and lentils.

Vitamin B12 Deficiency Anemia

Vitamin B12 is only found in meat products. Except for vegetarians, most cases of Vitamin B12 Deficiency Anemia are not due to low intake of B12. Instead, it is usually due to the lack of intrinsic factor resulting in poor Vitamin B12 absorption. Found in the stomach, intrinsic factor helps the body absorb Vitamin B12. This type of anemia is usually present in people with gastric bypass surgery or other chronic gastrointestinal diseases such as Crohn's disease. For most cases, Vitamin B12 shots are prescribed.
