This means an inadequate level of oxygen being carried around the body in the haemoglobin (red pigment) in the blood, therefore supply low oxygen to the bodies tissues.
Classic symptoms are:
Other symptoms may also be present.
The most common cause for anemia is low iron levels. Iron is essential for the formation of haemoglobin. Heavy bleeding, blood loss and pregnancy can cause low iron levels.
Vitamin B12 and folic acid are also essential for the formation of haemoglobin so a deficiency of these can also lead to anemia. These tend to be more chronic cases as we can store up to 2 years of B12 in the body so by the time we are deficient the body has lost a great amount of this vitamin. B12 is commonly found in meats so vegetarians can be more at risk along with those with Crohn’s disease and Coeliac disease due to absorption difficulties.
