Although anemia is uncommon in men but it can still occur and since it has many causes,it should be probed properly.
There are broadly three types of anemia like
1... Anemia due to blood loss like hemorrhoids,ulcers,gastritis,Cancers and use of pain killers
2... Anemia due to faulty red cell production like Iron deficiency
or VIT B 12 deficiency,stem cell or bone marrow fault like aplastic anemia
or due to chronic kidney condition,cancer,hypothyroidism
3... Anemia due to red cell destruction like haemolytic anemias.
There is no problem in advising various iron supplements
or diets like green leafy vegetables,fruits like apple,guava a,banana etc,dry fruits like almond and walnuts but the fact is you should consult a doctor and get to the cause of your anemia,since such a low anemia is rare in men.
