Iron deficiency (ID) in pregnant women can cause iron deficiency anaemia (IDA). ID is de-fined by low iron stores, measured by a low level of s-ferritin. Iron is essential for the synthesis of haemoglobin (Hb). Anaemia is defined by a low Hb level (<11.0 g/dL in 1st trimester, <10.5 g/dL in 2nd, and <10.5 - 11.0 g/dL in 3rd trimesters).
