Question

Iron-deficiency anemia frequently results from any of the following EXCEPT?

1) Inadequate dietary intake of iron
2) Chronic blood loss
3) Excessive iron absorption
4) Impaired iron absorption

Answer 1

Iron-deficiency anemia results from inadequate dietary intake, chronic blood loss, or impaired absorption, but not from excessive iron absorption. It's especially common in certain populations such as women of childbearing age, vegetarians, and individuals with gastrointestinal issues impacting iron uptake. The correct option is 3.

Step-by-step explanation:

Iron-deficiency anemia frequently results from a variety of causes, but not from excessive iron absorption. Instead, it is associated with conditions such as inadequate dietary intake of iron, chronic blood loss, or impaired iron absorption.

A lack of dietary iron is particularly common among teens, children, vegans, and vegetarians, and malabsorption from the gastrointestinal tract can also contribute to the iron deficit.

For example, during menstruation, women can lose iron, and therefore, older men and postmenopausal women usually have a negligible dietary requirement unless they have a deficiency. Overall, it is essential to ingest the recommended daily amounts of iron and to ensure efficient absorption to prevent iron-deficiency anemia.
