Clinical history, presentation, and findings include fatigue, pallor, dyspnoea on exertion, and pica.
Microcytic, hypochromic anaemia; low reticulocyte count.
Characteristics include low serum iron, increased total iron-binding capacity (TIBC), less than 16% transferrin saturation, and low serum ferritin.
The diagnosis of iron deficiency anaemia necessitates investigation of the underlying cause.
Initial treatment includes oral iron.
The WHO defines anaemia as haemoglobin <130 g/L (13 g/dL) in men older than age 15 years, <120 g/L (12 g/dL) in non-pregnant women older than age 15 years, and <110 g/L (11 g/dL) in pregnant women. Iron deficiency is a lack of iron in the body resulting from inadequate iron intake, increased iron loss, or excessive iron requirements of which iron deficiency anaemia (IDA) is the end-stage result.
