erm think u guys might have got the definition of IDA wrongly
IDA basically means anemia (low hemoglobin (low blood cells)) secondary to iron deficiency
Anemia may occur due to many causes such as B12 deficiency,folate deficiency etc.not only due to iron deficiency

When u have iron deficiency,u may have a huge array of symptoms which includes easy tiredness,inactivity,etc.severe forms may include shortness of breath,dizziness,chest pains,palpitations etc.

Iron deficiency may be caused by
decreased iron absorption e.g decreased iron intake,hookworm infestations etc.
Increased iron loss/iron usage e.g. Pregnancy,internal bleed,severe forms of periods (menorrhagia),per rectal bleed,etc.

Treatment may range from from regular iron supplementation e.g Ferrous sulphate,ferrous fumarate,iron Imferon injections to blood transfusions if the hb drops below 8g/dl.

Its not anemia caused by standing up after siting down for a long time.
