it seems my anemia has been caused by very heavy period.

I am very anemic (iron deficiency anemia),hemoglobin is only 7.2 (in May,2008  it was even lower, only 5.0).

I have no other problems,it seems my anemia has been caused by very heavy period. I was even admitted to hospital to get checked on the day blood test taken Here very often it needs months to be admitted into hospital---I thought I was regarded as very emergency ,and also asked to have blood  transfusion (I refused) . The medical people ruled out other problems,they only could reckon  my anemia has been caused by very heavy period.
