Iron deficiency anemia can develop gradually and is often caused by insufficient dietary iron intake, poor absorption of iron, or blood loss. It is particularly prevalent in women of childbearing age, children, and pregnant women, as these groups have higher iron needs. However, anyone can be affected by this condition.
The causes of iron deficiency anemia vary. Inadequate iron intake is the most common cause, which can result from diets that are low in iron-rich foods such as red meat, poultry, seafood, and fortified cereals. Additionally, certain health conditions can impair the body’s ability to absorb iron, such as celiac disease, Crohn’s disease, or gastrointestinal surgery. Blood loss, whether due to heavy menstrual periods, gastrointestinal bleeding, or trauma, is another significant cause of iron deficiency anemia.
