Iron deficiency anemia (IDA) is the most common cause of anemia worldwide…It starts as normocytic anemia (normal MCV) and then shifts into microcytic anemia (low MCV).
Causes include decreased supply (a nutritional deficiency, malabsorption syndrome) or increased demand (pregnancy, lactation, growth), blood loss is also a common cause (menstruation or gastrointestinal bleeding).
Clinical symptoms of iron deficiency anemia include pica, glossitis, achlorhydria (indigestion), fatigue, pallor, exercise intolerance, flow murmurs, and even angina.
Restless leg syndrome is associated with iron deficiency anemia.
Anemia can be classified as microcytic (low MCV; or mean corpuscular volume), normocytic (normal MCV) and macrocytic (High MCV).
The normal MCV level is about 76 to 96 fL.
