Do I have Iron deficiency/Anaemia?
You should never take iron supplements unless you are instructed to do so by a doctor. The best thing for you to do is make an appointment and get your hemoglobin and ferritin levels tested. It is not actually that common for vegetarians to be iron deficient, and the cause should be investigated (some more serious but not as common causes are certain illnesses and internal bleeding). Iron overload (called hemochromatosis) can be hereditary, so you really need to know if you are iron deficient or not before you take any more iron. Some of the early symptoms of hemochromatosis are the same as iron deficiency anemia, so you need a doctor to figure it out. Iron overload is very dangerous and can cause damage to internal organs.
