Question

In general, iron deficiency is usually caused by dietary lack or blood loss. What are some examples of conditions that can lead to iron deficiency?

1) Malnutrition
2) Malabsorption
3) Chronic bleeding
4) Other

Answer 1

Iron deficiency can occur due to malnutrition, malabsorption, chronic bleeding, increased demand during growth or pregnancy, and conditions like pernicious anemia. Adequate dietary intake of iron and proper management of underlying conditions are crucial in preventing anemia.

Step-by-step explanation:

Iron deficiency can be caused by various conditions, including:

1. Malnutrition: A diet lacking in adequate iron, particularly prevalent in vegetarians and vegans due to the non-absorbability of plant-based iron.
2. Malabsorption: Conditions such as celiac disease or Crohn's disease impair the absorption of iron in the gastrointestinal tract.
3. Chronic bleeding: Losses from menstrual blood, gastrointestinal bleeding from ulcers or cancers, and chronic aspirin ingestion can lead to significant iron deficiency.
4. Increased demand: Situations like pregnancy or rapid growth during infancy require more iron, potentially leading to deficiency if not matched with adequate intake.

Conditions such as the autoimmune disorder pernicious anemia, which impedes vitamin B12 absorption, can contribute to iron deficiency. Additionally, certain lifestyle factors like excessive alcohol consumption and the use of some medications can exacerbate the problem. Ensuring sufficient iron intake, either through diet or supplements, is essential for preventing anemia.
